|

|
| + (.x.1): Don't use neutralize.
|
| + (edit): Don't substitute for ID.
|
| + (Doxyfile): Don't define Id, and thus don't depend on ChangeLog.
|
| +
|
| +2008-07-27 Joel E. Denny <jdenny@ces.clemson.edu>
|
| +
|
| + Fix dependence on computed configure variables.
|
| + * doc/Makefile.am (common_dep): Depend on $(top_srcdir)/configure not
|
| + $(top_srcdir)/configure.ac so that changes to computed variables, such
|
| + as PACKAGE_VERSION, are seen.

|
| + (EXTRA_DIST): Remove GNUmakefile, handled by Gnulib. Add maint.mk,
|
| + .prev-version, and .version.
|
| + * NEWS (2.3b+): Rename to...
|
| + (?.?): ... this because we're dropping the "+" version naming scheme,
|
| + but, in general, we still can't be sure of our next release name.
|
| + * bootstrap: Add a quick hack to remove from .gitignore the
|
| + GNUmakefile entry that gnulib adds. We already have a /GNUmakefile
|
| + entry. This should really be fixed in gnulib instead.
|
| + * bootstrap.conf (gnulib_modules): Add gnumakefile.

| + Fix some .gitignore and .cvsignore problems.
|
| + * bootstrap (insert_sorted_if_absent): Replace all uses with...

|
| + .gitignore entries before passing them to insert_sorted_if_absent.
|
| + * bootstrap.conf (vc_ignore): Set to '.cvsignore .gitignore' so that
|
| + .cvsignore files are maintained even though Bison developers run
|
| + bootstrap while using Git.
|
| + * .cvsignore (*.patch *.log log patches applied): Remove, apparently
|
| + unneeded by Bison.
|
| + (gnulib): Add.
|
| + * .gitignore (/*.patch *.log log patches applied): Remove, broken and
|
| + unneeded. Reported by Eric Blake.
|
| + * lib/.gitignore (/*~): Add.
|
| + * po/.cvsignore, runtime-po/.cvsignore: Sync with .gitignore.
|
| + * examples/calc++/.gitignore (/calc++.exe): Add. Reported by Eric
|
| + Blake.

|
| + (/setenv.m4): Add.
|
| + * src/output.c (output_skeleton): For the m4 invocation, pass -dV as
|
| + the first argument because it may become position-dependent, and unset
|
| + POSIXLY_CORRECT so Bison's skeletons have access to GNU M4 extensions.
|
| + Add comments explaining these issues in more detail.
|
| +
|
| +2008-07-14 Joel E. Denny <jdenny@ces.clemson.edu>

| + Revert prior patch, by working around autoconf regression.
|
| + * tests/output.at (m4_expand): Add workaround for autoconf 2.62.

|
| +
|
| + Work-around an Autoconf 2.62 AT_SETUP bug that was not present in
|
| + 2.61. Reported by Juan Manuel Guerrero at
|
| + <http://lists.gnu.org/archive/html/bug-bison/2008-04/msg00011.html>.
|
| + * tests/output.at ("Output file name: ("): Comment out test case for
|
| + now.
|
| + ("Output file name: )"): Likewise.
|
| +
|
| +2008-04-21 Joel E. Denny <jdenny@ces.clemson.edu>
|
| +
|
| + * GNUmakefile: Update git-version-gen invocation so make dist
|
| + succeeds.
|
| +
|
| +2008-04-21 Joel E. Denny <jdenny@ces.clemson.edu>
|
| +
|
| + Update to the current gnulib CVS repository, and fix trigraph handling
|
| + in Bison.
|
| + * bootstrap: Update gnulib CVS repository URL.
|
| + (symlink_to_dir): Encapsulate the code that guarantees the destination
|
| + directory exists into...
|
| + (check_dst_dir): ... this new function, and...
|
| + (cp_mark_as_generated): ... reuse it here so that bootstrap doesn't
|
| + fail when copying files into lib/uniwidth/.
|
| + * src/output.c (prepare_symbols): When writing yytname muscles, where
|
| + symbol names will be encoded in C-string literals, tell quotearg to
|
| + escape trigraphs. This used to be the default in gnulib.
|
| + * tests/regression.at (Token definitions): Because of the change in
|
| + gnulib's quotearg behavior, string_as_id in parse-gram.y no longer
|
| + escapes trigraphs in symbol names. Thus, yytname no longer has
|
| + trigraphs unnecessarily doubly escaped. Update test case output.
|
| + Extend test case to be sure Bison's own error messages will no longer
|
| + have trigraphs in symbol names unnecessarily escaped once.

| +
|
| + * NEWS (2.3a+): Mention that -g now takes an argument.
|
| + * doc/bison.texinfo (Bison Options): Reword -W entry a little for
|
| + consistency. Update the -g and -x entries now that they take
|
| + arguments. Use brackets to indicate optional arguments.
|
| + * src/getargs.c (usage): Explain the relationship between arguments of
|
| + long and short options more completely. Document --defines and -d
|
| + separately since the former takes an argument but, for POSIX Yacc, the
|
| + latter does not.

| + (short_options): Let -W take an optional argument like --warnings.
|
| + (getargs): Sort cases.

|
| +
|
| + * src/getargs.c (short_options): Split and sort for readability.
|
| + -g and -x take optional arguments, just like their long options.
|
| + * build-aux/cross-options.pl: Use /x to make the regexp easier to
|
| + understand.
|
| + Fix the handling of $opt which resulted in all the argument to be
|
| + considered as optional.
|
| +
|
| +2008-02-22 Joel E. Denny <jdenny@ces.clemson.edu>

|
| +
|
| + Improve C++ namespace support. Discussed starting at
|
| + <http://lists.gnu.org/archive/html/help-bison/2007-09/msg00016.html>.
|
| + * data/c++.m4: (b4_namespace_ref, b4_namespace_open,

| + the above macros.
|
| + * data/lalr1.cc (b4_namespace): Likewise.
|
| + * data/location.cc (b4_namespace): Likewise.
|
| + * doc/bison.texinfo (Decl Summary): Move `%define push_pull' entry
|
| + inside a new table in the general %define entry. Document `%define
|
| + namespace' there as well. Point the %name-prefix entry to it since it
|
| + explains it more completely in the case of C++.
|
| + (C++ Bison Interface): Mention `%define namespace' instead of
|
| + %name-prefix.
|
| + (Table of Symbols): Remove the `%define push_pull' entry. The %define
|
| + entry suffices.
|
| + * tests/c++.at (Relative namespace references): New test case.
|
| + (Absolute namespace references): New test case.
|
| + (Syntactically invalid namespace references): New test case.

| +
|
| +2007-10-07 Joel E. Denny <jdenny@ces.clemson.edu>
|
| +
|
| + Fix some error-reporting macro bugs.
|
| + * data/bison.m4 (b4_cat): New.
|
| + (b4_error, b4_error_at): Use b4_cat to send error directives directly
|
| + to stdout so they don't become arguments to other macros. Update
|
| + comments and add examples.
|
| + (b4_warn, b4_warn_at, b4_complain, b4_complain_at): Update comments and
|
| + add examples.
|
| + (b4_fatal, b4_fatal_at): Likewise, and invoke m4_exit(1) immediately
|
| + after printing the error directive so that M4 doesn't report subsequent
|
| + problems that are induced by this problem.
|
| + * src/scan-skel.l: Recognize @` digraph outside of directive arguments
|
| + instead of just in them. Recognize @\n in both places. Both expand to
|
| + the empty string. Needed by b4_cat.
|
| + * tests/skeletons.at (Complaining during macro argument expansion):
|
| + New test case.
|

|
| + definitions...
|
| + * data/push.c: ... to here and compute them from the value of the
|
| + %define variable push_pull.
|
| + * data/c-skel.m4: Instead of choosing the push.c skeleton for push
|
| + parsing requests here...
|
| + * data/yacc.c: ... hack this to switch to push.c any time
|
| + b4_use_push_pull_flag or the %define variable push_pull is set. This
|
| + will go away when we mv push.c yacc.c.
|
| + * data/c++-skel.m4, data/glr.c, data/java-skel.m4: Don't report that
|
| + push parsing is not supported since unused %define variables are
|
| + reported anyway.
|
| + * src/getargs.c, src/getargs.h (pull_parser, push_parser): Remove.

|
| +2007-09-21 Paul Eggert <eggert@cs.ucla.edu>
|
| +
|
| + * src/gram.c (rule_rhs_print_xml): Now static, since it isn't used
|
| + elsewhere.
|

|

| +
|
| +2007-08-11 Joel E. Denny <jdenny@ces.clemson.edu>
|
| +
|
| + * tests/push.at (Push Parsing: Memory Leak for Early Deletion): Do not

|
| + * tests/torture.at (AT_DATA_STACK_TORTURE): Do not name user variables

|
| +2007-08-03 Joel E. Denny <jdenny@ces.clemson.edu>
|
| +
|
| + * data/yacc.c (yyexhaustedlab): Define it when YYERROR_VERBOSE is
|
| + true since it's then always used regardless of whether yyoverflow is
|
| + defined. Reported by Christian Burger at
|
| + <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00031.html>.
|

|
| + * ChangeLog: For changes in doc/bison.texinfo, consistently reference
|
| + node names: say "Decl Summary" not "Bison Declaration Summary".
|
| +
|
| +2007-07-28 Joel E. Denny <jdenny@ces.clemson.edu>
|
| +
|
| + * src/muscle_tab.c (muscle_percent_define_flag_if): In order to
|
| + determine whether this function has already complained about an invalid
|
| + value for a %define boolean variable, don't check whether Bison has
|
| + ever examined the value. As written, the check was a tautology.
|
| + Instead, record and check for this complaint using a separate muscle.

|

|
| + Fix push parsing memory leak reported by Brandon Lucia at
|
| + <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00032.html>.
|
| + * THANKS: Add Brandon Lucia.
|
| + * data/push.c (yypstate_delete): Free the stack if it was reallocated
|
| + but the parse never completed and thus freed it.
|
| + * tests/Makefile.am (TESTSUITE_AT): Add push.at.
|
| + * tests/testsuite.at: Include push.at.
|
| + * test/push.at: New.

|
| +2007-07-17 Joel E. Denny <jdenny@ces.clemson.edu>
|
| +
|
| + Improve handling of multiple S/R conflicts in the same state and of S/R
|
| + conflicts involving multiple reductions.
|
| + * src/conflicts.c (resolve_sr_conflict): Don't assign the error action
|
| + set for a state here or Bison will abort if it is reassigned on a
|
| + later conflicted reduction in the same state.
|
| + Similarly, don't finalize and assign the solved conflicts report here
|
| + or it will be lost if it is reassigned on a later conflicted reduction
|
| + in the same state.
|
| + (set_conflicts): Instead, assign them both here after all S/R conflicts
|
| + in the state have been fully examined.
|
| + * src/print.c (shift_set): Rename to...
|
| + (no_reduce_set): ... this.
|
| + (print_reductions): Update for rename, and add %nonassoc error action
|
| + tokens to no_reduce_set so that, when printing the first remaining
|
| + reduction on an error action token, the reduction is enclosed in
|
| + brackets.
|
| + (print_results): Update for rename.
|
| + * tests/conflicts.at (Solved conflicts report for multiple reductions
|
| + in a state): New test case.
|
| + (%nonassoc error actions for multiple reductions in a state): New test
|
| + case.
|
| +
|
| + * src/main.c (main): Don't depend on C99 features.
|
| +
|
| +2007-07-16 Joel E. Denny <jdenny@ces.clemson.edu>
|
| +
|
| + * build-aux/.cvsignore: Add compile.
|
| + * lib/.cvsignore: Add charset.alias, ref-add.sed, ref-del.sed, and
|
| + uniwidth.
|
| +
|
| +2007-07-10 Joel E. Denny <jdenny@ces.clemson.edu>
|
| +
|
| + * bootstrap (slurp): Create target directories that don't exist.
|
| + Specifically, we need lib/uniwidth/ because of recent Gnulib changes.
|
| +
|
| +2007-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
|
| +
|
| + * LR0.c (new_itemsets): Fix wording in comments: say item index rather
|
| + than item number.
|
| + * closure.c (closure): Likewise.
|
| + * state.h (reductions): Comment sorting of rules.
|
| + (state): Comment sorting of items.
|
| +
|
| +2007-07-02 Joel E. Denny <jdenny@ces.clemson.edu>
|
| +
|
| + Fix C++ test cases after recent Gnulib changes. Discussed starting at
|
| + <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00000.html>.
|
| + * examples/calc++/Makefile.am (DEFAULT_INCLUDES): Override Automake's
|
| + definition in order to avoid Gnulib headers since we don't use config.h
|
| + here.
|
| + * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): Use AT_DATA_GRAMMAR
|
| + rather than AT_DATA so that config.h is included.
|
| +
|
| +2007-07-01 Joel E. Denny <jdenny@ces.clemson.edu>
|
| +
|
| + * data/glr.c (yy_yypstack, yypstates, yypdumpstack): Use YYFPRINTF
|
| + instead of fprintf. Guard these functions with #if YYDEBUG instead of
|
| + #ifdef YYDEBUG for consistency with all other uses of YYDEBUG in Bison
|
| + and so that YYFPRINTF is guaranteed to be defined here.
|
| +
|
| +2007-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
|
| +
|
| + * src/muscle_tab.c (muscle_percent_define_invalid_value): Replace
|
| + with...
|
| + (muscle_percent_define_check_values): ... this more helpful function.
|
| + Again, it's not used yet, but it will be.
|
| + * src/muscle_tab.h: Likewise.
|
| +
|
| + Improve some comments in parser table construction.
|
| + * src/LR0.c (new_itemsets): Explain sorting of itemset and kernel_base.
|
| + (generate_states): Don't mention ruleset, which is internal to closure.
|
| + * src/closure.c (closure): Explain sorting of core and itemset, which
|
| + is required for this function to behave correctly.
|
| + * src/closure.h (closure): Mention sorting.
|
| +
|
| +2007-05-28 Joel E. Denny <jdenny@ces.clemson.edu>
|
| +
|
| + * src/lalr.c (state_lookahead_tokens_count): For code readability,
|
| + move the check for disabled transitions to an aver since conflict
|
| + resolution hasn't happened yet.
|
| +
|
| + * src/lalr.c (state_lookahead_tokens_count): Remove the check that
|
| + labels a state as inconsistent just because it has error transitions.
|
| + The original form of this check appeared in revision 1.1 of lalr.c,
|
| + which was committed on 1991-12-21. Now (at least), changing the
|
| + consistency label on such a state appears to have no useful effect in
|
| + any of the places it is examined, which I enumerate below. The key
|
| + point to understanding each item in this enumeration is that a state
|
| + with an error transition is labelled consistent in the first place only
|
| + if it has no rules, so the check cannot matter for states that have
|
| + rules. (1) Labelling a state as inconsistent will cause set_conflicts
|
| + to try to identify its conflicts, and a state must have *rules* to have
|
| + conflicts. (2) Labelling a state as inconsistent will affect how
|
| + action_row sets the default *rule* for the state. (3) Labelling a
|
| + state as inconsistent will cause build_relations to add lookback edges
|
| + to *rules* in that state.
|
| + * src/state.h (struct state): Word the comment for member consistent
|
| + more carefully.
|
| +
|
| +2007-05-27 Joel E. Denny <jdenny@ces.clemson.edu>
|
| +
|

|
| + * src/reader.c (check_and_convert_grammar): Fix for-loop.

|
| + (state_remove_unreachable_states): Fix for-loop.
|
| +
|
| + Don't widen struct state with member reachable just to temporarily
|
| + record reachability. Instead, use a local bitset.
|
| + * src/state.h (struct state): Remove member.
|
| + * src/state.c (state_new): Don't initialize it.
|
| + (state_mark_reachable_states): Rename to...
|
| + (state_record_reachable_states): ... this, and use bitset.
|
| + (state_remove_unreachable_states): Use bitset.

|
| +
|

| + the case of pure parsers. Reported by Frans Englich at
|
| + <http://lists.gnu.org/archive/html/help-bison/2007-05/msg00018.html>.

|
| +
|
| + Extend the front-end API for %define variables to more completely

| + <http://lists.gnu.org/archive/html/bug-bison/2007-02/msg00016.html>.
|

|
| +
|
| +2007-02-11 Joel E. Denny <jdenny@ces.clemson.edu>
|
| +
|
| + * data/Makefile.am: Update copyright date.
|
| + * data/push.c (yypull_parse): Report memory exhaustion and return 2 if
|
| + yypstate_new returns NULL.
|
| + (yypstate_new): Return NULL if malloc does.
|
| + * src/reader.c (packgram): Move translation of rule actions from the
|
| + beginning of packgram to...
|
| + (check_and_convert_grammar): ... here right before packgram is invoked
|
| + so it's easier to write more complete comments, and remove redundant
|
| + code.
|
| +
|
| +2007-02-10 Joel E. Denny <jdenny@ces.clemson.edu>
|
| +
|
| + As in semantic actions, make @$ in %initial-action, %destructor, and
|
| + %printer imply %locations.
|
| + * src/scan-code.l (SC_SYMBOL_ACTION): Set locations_flag = true when
|
| + scanning @$.
|
| + * tests/actions.at (AT_CHECK_ACTION_LOCATIONS): New macro supporting...
|
| + (@$ in %initial-action implies %locations,
|
| + @$ in %destructor implies %locations,
|
| + @$ in %printer implies %locations): ... these new test cases.
|
| +
|
| +2007-02-07 Paul Eggert <eggert@cs.ucla.edu>
|
| +
|
| + Undo most of the 2007-02-03 change, switching to the strcase module
|
| + now that gnulib strcase has been fixed.
|
| + * bootstrap.conf (gnulib_modules): Remove c-strcase. Add strcase.
|
| + * lib/.cvsignore: Remove c-ctype.c, c-ctype.h, c-strcase.h,
|
| + c-strcasecomp.c, c-strncasecmp.c. Add strcasecmp.c, strncasecmp.c
|
| + * m4/.cvsignore: Add strcase.m4.
|
| + * src/getargs.c: Revert 2007-02-03 change, as follows.
|
| + Don't include c-strcase.h.
|
| + (language_argmatch): Use strcasecmp rather than c_strcasecmp.
|
| + strcasecmp has "unspecified behavior" outside the POSIX locale,
|
| + but it works fine in practice if at least one argument is ASCII,
|
| + as is the case in Bison.

|
| +2007-02-07 Paolo Bonzini <bonzini@gnu.org>
|
| +
|
| + * tests/java.at: Skip tests if only one of javac/java is present.
|
| + Reported by Joel E. Denny.

| + * tests/atlocal.in: Adjust copyright years.
|
| +
|
| +2007-02-05 Paolo Bonzini <bonzini@gnu.org>
|
| +
|
| + * data/lalr1.java (Stack): Work around old verifiers that disallow
|
| + access to the private fields of an inner class, from the outer class.
|
| + We can make Stack's fields public because user code doesn't have access
|
| + to the instance of Stack used by parse(). Reported by Paul Eggert.
|
| +
|
| +2007-02-03 Paul Eggert <eggert@cs.ucla.edu>
|
| +
|
| + * .cvsignore: Add javacomp.sh, javaexec.sh. Is this really
|
| + the right spot for these files?
|
| + * bootstrap.conf (gnulib_modules): Add c-strcase.
|
| + * lib/.cvsignore: Add c-ctype.c c-ctype.h, c-strcasecomp.c,
|
| + c-strncasecmp.c.
|
| + * src/getargs.c: Include c-strcase.h.
|
| + (language_argmatch): Use c_strcasecmp rather than strcasecmp,
|
| + to avoid unspecified behavior.
|
| +

|
| + * data/bison.m4 (b4_percent_define_flag_if): Don't treat 0 as false.

|
| + * data/Makefile.am: Add new files.

|
| +2007-01-28 Joel E. Denny <jdenny@ces.clemson.edu>
|
| +
|
| + Clean up.
|
| + * src/scan-skel.l (at_directive_perform): Add at_directive_argc and
|
| + at_directive_argv arguments so these no longer have to be global
|
| + variables. Also, update the implementation for the following changes.
|
| + (fail_for_at_directive_too_many_args,
|
| + fail_for_at_directive_too_few_args): Add at_directive_name argument.
|
| + (at_directive_name): Remove as at_directive_argv[0] will be used for
|
| + this now.
|
| + (AT_DIRECTIVE_ARGC_MAX): Increment to make space in at_directive_argv
|
| + for the directive name.
|
| + (at_directive_argc, at_directive_argv): Make these local within
|

|
| +
|
| +2007-01-27 Joel E. Denny <jdenny@ces.clemson.edu>
|
| +
|
| + * ChangeLog: For changes in doc/bison.texinfo, consistently reference
|
| + node names: say "Table of Symbols" not "Bison Symbols", and say "Decl
|
| + Summary" not "Directives".
|
| + * doc/bison.texinfo (Decl Summary, Calc++ Parser): Cross-reference the
|
| + %code entry in "Decl Summary" rather than the one in "Table of Symbols"
|
| + since the former is now the more complete one.
|
| + (Prologue Alternatives): Likewise and do the same for %defines.
|
| + (Table of Symbols): Add summary of %code, add summary of %define, and
|
| + move full %code documentation to...
|
| + (Decl Summary): ... here for consistency with other entries in these
|
| + sections.
|
| + Move %define entry in order to keep this list alphabetized.
|
| + Reword %define entry a little to put less emphasis on the skeleton
|
| + concept, which most users shouldn't have to think about.
|
| +
|
| +2007-01-26 Paul Eggert <eggert@cs.ucla.edu>
|
| +
|
| + Adjust to recent gnulib changes.
|
| + * lib/.cvsignore: Remove stpcpy.h, strndup.h, strnlen.h.
|
| + Add string.h, string_.h, unistd_.h, wchar_.h.
|
| + * m4/.cvsignore: Add gnulib-common.m4, string_h.m4, wchar.m4.
|
| + * src/system.h: Don't include <stpcpy.h>; this is now done by
|
| + <string.h>.
|
| +
|
| +2007-01-23 Paolo Bonzini <bonzini@gnu.org>
|
| +
|
| + Simplify implementation of unqualified %code, implement macros for
|
| + uniform treatment of boolean %define flags. Document %define.
|
| + * data/bison.m4 (b4_percent_define_ifdef, b4_percent_define_flag_if,
|
| + b4_percent_code_ifdef): New.
|
| + (b4_percent_code_get): Map unqualified %code to b4_percent_code().
|
| + * data/c++.m4: Define default value for global_tokens_and_yystype.
|
| + * data/glr.cc: Likewise.

|
| + If the specified skeleton file name contains a `/', don't prepend
|
| + pkgdatadir.
|
| + * src/parse-gram.y (prologue_declaration): If the specified skeleton

|
| + * tests/Makefile.am (TESTSUITE_AT): Add skeletons.at.
|
| + * skeletons.at: New file.

|
| +
|
| + Clean up %define and %code implementation in M4 some. Most
|
| + importantly, rename all related macros to be in the b4_percent_define
|
| + and b4_percent_code namespaces. Also, complete support for `.' in
|
| + %define variable names and %code qualifiers.
|

|

| + Extend documentation with examples.
|
| + For SKELETON-NAMESPACE (as documented for b4_check_user_names), use

| + b4_percent_define_skeleton_variables and
|
| + b4_percent_code_skeleton_qualifiers.
|
| + Expect any value for the %define variable `foo' to be stored in the

|
| + * data/glr.c, data/glr.cc, data/lalr1.cc, data/push.c, data/yacc.c: Add

| + post_prologue_obstack.
|
| + * src/parse-gram.y (prologue_declaration): Use muscle_code_grow rather
|
| + than prologue_augment for prologue parsing so you don't need prologue
|
| + obstacks.
|
| + (grammar_declaration): For %union RHS, use `braceless' instead of
|

|
| +
|
| + Instead of having skeletons declare all valid %define variables and
|
| + %code qualifiers, provide macros that retrieve the associated values
|
| + and build these lists automatically. Thus Bison will now warn when a
|
| + variable or qualifier is not used by the skeleton in the current
|
| + invocation regardless of whether it might sometimes be used by that
|
| + skeleton in other invocations. Also, move all %define value macros to
|
| + the b4_percent_define_ namespace, and remove the %define "NAME" {CODE}
|
| + form, which is replaced by %code.
|
| + * data/bison.m4 (b4_check_for_unrecognized_names): Rename to...
|
| + (b4_check_user_names): ... this, and change the series of valid name
|
| + arguments to a single list argument for names used in the skeleton
|
| + similar to the existing list argument for names used in the grammar.
|
| + Warn instead of complaining.
|
| + (b4_get_percent_define, b4_get_percent_code): New to retrieve %define
|
| + values and %code code, to format %code code properly, and to build
|
| + lists of all %define variables and %code qualifiers used in the
|
| + skeleton: b4_skeleton_percent_define_variables and
|
| + b4_skeleton_percent_code_qualifiers.
|
| + (b4_check_percent_define_variables, b4_check_percent_code_qualifiers):
|
| + Remove, and...
|
| + (m4_wrap): ... m4_wrap b4_check_user_names invocations instead so that
|
| + the skeleton names lists can finish building first. In place of
|
| + b4_used_percent_define_variables and b4_used_percent_code_qualifiers,
|
| + expect the lists b4_user_percent_define_variables and
|
| + b4_user_percent_code_qualifiers.
|
| + * data/c++.m4: Where setting default values for b4_parser_class_name,
|

|
| + b4_percent_define_ namespace.
|

|
| + * data/push.c: Don't use b4_check_percent_define_variables and

|
| + * data/yacc.c: Likewise, and don't call m4_exit in

| + Rename to...
|
| + (muscle_grow_user_name_list): ... this for consistency with the
|
| + terminology used in bison.m4.
|
| + * src/parse-gram.y (prologue_declaration): Prepend "percent_define_" to
|
| + %define variable names, and rename muscle used_percent_define_variables
|
| + to user_percent_define_variables.
|
| + (grammar_declaration): Rename muscle used_percent_code_qualifiers to
|
| + user_percent_code_qualifiers.
|
| + (content): Remove.
|
| + (content.opt): Replace content RHS with STRING RHS so %define "NAME"
|
| + {CODE} form is no longer accepted.
|
| + * tests/input.at (Reject bad %code qualifiers): Rename to...
|
| + (Reject unused %code qualifiers): ... this, and update test output.
|
| + (%define error): Update test output.
|
| +
|
| +2007-01-07 Joel E. Denny <jdenny@ces.clemson.edu>
|
| +
|
| + Check for unrecognized %define variables similar to checking for
|
| + unrecognized %code qualifiers. Check for redefined %define variables.
|
| + * data/bison.m4 (b4_check_for_unrecognized_names): New macro that
|
| + generalizes...
|
| + (b4_check_percent_code_qualifiers): ... this, which now wraps it.
|
| + (b4_check_percent_define_variables): New, also wraps it.
|
| + * data/glr.c: Unless glr.cc is wrapping glr.c, declare no valid %define
|
| + variables using b4_check_percent_define_variables.
|
| + * data/glr.cc, data/lalr1.cc: Declare the valid %define variables as
|
| + all those exercised in the test suite and all those listed in the
|
| + `Default values' section of c++.m4. Are there others?
|
| + * data/push.c, data/yacc.c: Declare no valid %define variables.
|
| + * src/muscle_tab.c, src/muscle_tab.h (muscle_find_const): New function,
|
| + similar to muscle_find, but it works even when the muscle stores a
|
| + const value.
|
| + (muscle_grow_used_name_list): New function for constructing the used
|
| + name list muscles that b4_check_for_unrecognized_names requires.
|
| + * src/parse-gram.y (prologue_declaration): Warn if a variable is
|
| + %define'd more than once. Define the b4_used_percent_define_variables
|
| + muscle with muscle_grow_used_name_list.
|
| + (grammar_declaration): Abbreviate %code code with
|
| + muscle_grow_used_name_list.
|
| + * tests/input.at (%define errors): New.
|
| +
|
| +2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
|
| +
|
| + Provide warn_at, complain_at, and fatal_at function callbacks to the
|
| + skeletons, and use this for %code qualifier complaints.
|
| + * data/bison.m4 (b4_error_at): New, invoked by...
|
| + (b4_warn_at, b4_complain_at, b4_fatal_at): ... these new macros to wrap
|
| + the skeleton scanner's new @warn_at(...@), @complain_at(...@), and
|
| + @fatal_at(...@) directives.
|
| + (b4_check_percent_code_qualifiers): Rewrite to expect locations for
|
| + qualifiers in b4_used_percent_code_qualifiers and to use
|
| + b4_complain_at.
|
| + * src/location.c, src/location.h (boundary_set_from_string): New global
|
| + function.
|
| + * src/muscle_tab.c, src/muscle_tab.h (muscle_boundary_grow): New global
|
| + function.
|
| + * src/parse-gram.y (grammar_declaration): Add locations for qualifiers
|
| + to b4_used_percent_code_qualifiers.
|
| + * src/scan-skel.l (fail_for_at_directive_too_few_args): New static
|
| + function.
|
| + (AT_DIRECTIVE_ARGC_MAX): Increase for boundary arguments.
|
| + (lineno): Rename to...
|
| + (out_lineno): ... this so I don't misunderstand it again.
|
| + (SC_AT_DIRECTIVE_SKIP_WS): Don't increment out_lineno for newlines
|
| + here; these newlines are in the input but not the output file.
|
| + (SC_AT_DIRECTIVE_ARG): Likewise. Extract directive execution to...
|
| + (at_directive_perform): ... this new static function, and add handling
|
| + of new @warn_at(...@), @complain_at(...@), and @fatal_at(...@)
|
| + directives.
|
| + * tests/input.at (Reject bad %code qualifiers): Update test output with
|
| + locations and extend.
|
| +
|
| + * tests/output.at (Output file name: [, Output file name: ]): Remove
|
| + bogus comment about these tests failing.

|
| +2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
|
| +
|
| + Clean up b4_check_percent_code_qualifiers a little.
|
| + * data/bison.m4 (b4_check_percent_code_qualifiers): Expect qualifiers
|
| + in b4_used_percent_code_qualifiers to be double-M4-quoted. Rewrite
|
| + documentation and add examples.
|
| + * src/parse-gram.y (grammar_declaration): Double-M4-quote those
|
| + qualifiers here.
|
| +
|
| +2007-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
|
| +
|
| + Don't use m4_divert since it makes m4_divert_push and m4_divert_pop
|
| + unreliable -- especially when they're hidden inside another macro.
|
| + * data/bison.m4, data/c++-skel.m4, data/c++.m4, data/c-skel.m4,
|
| + data/c.m4: Remove m4_divert(-1).
|
| + * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
|
| + data/push.c, data/yacc.c: Likewise, and replace m4_divert(0) with
|
| + m4_divert_push(0) and m4_divert_pop(0).
|
| + * src/output.c (output_skeleton): Don't add an m4_divert_push(0) and
|
| + an m4_wrap([m4_divert_pop(0)]) to the M4. Diversion -1, which is
|
| + pushed and popped by m4sugar, should be first on the stack.
|
| +
|
| + Provide warn, complain, and fatal function callbacks to the skeletons.
|
| + This provides more flexibility than m4_fatal, improves the error
|
| + message format, and captures messages for translation. Discussed
|
| + starting at
|
| + <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00063.html>.
|
| + * data/bison.m4 (b4_error): New, invoked by...
|
| + (b4_warn, b4_complain, b4_fatal): ... these new macros to wrap the
|
| + skeleton scanner's new @warn(...@), @complain(...@), and @fatal(...@)
|
| + directives. Because these M4 macros might be called when the current
|
| + diversion is -1 or 0, m4_divert_push and m4_divert_pop is used; thus
|
| + the previous removal of uses of m4_divert, which caused trouble.
|
| + (b4_check_percent_code_qualifiers): Use b4_complain instead of
|
| + m4_fatal to report unrecognized %code qualifiers.
|
| + * data/c++-skel.m4: Use b4_complain instead of m4_fatal to report C++
|
| + push parser requests.
|
| + * data/glr.c: Use b4_complain instead of m4_fatal to report
|
| + non-deterministic push parser requests.
|
| + Update @output usage to @output(...@) form.
|
| + * data/glr.cc, data/lalr1.cc: Use b4_fatal instead of m4_fatal to
|
| + report missing %defines. Update @output usage to @output(...@) form.
|
| + * data/location.cc, data/push.c, data/yacc.c: Update @output usage to
|
| + @output(...@) form.
|
| + * src/main.c (main): Invoke skel_scanner_free.
|
| + * src/scan-skel.h (skel_scanner_free): Prototype new function.
|
| + * src/scan-skel.l (FLEX_NO_OBSTACK): Don't define; we now need the
|
| + obstack_for_string from flex-scanner.h.
|
| + (YY_DECL): Use to declare skel_lex static.
|
| + (decode_at_digraphs): Remove; now handled in the new
|
| + SC_AT_DIRECTIVE_ARG start condition.
|
| + (fail_for_at_directive_too_many_args, fail_for_invalid_at): New static
|
| + functions.
|
| + (at_directive_name, AT_DIRECTIVE_ARGC_MAX, at_directive_argc,
|
| + at_directive_argv): New static globals.
|
| + (INITIAL): Use fail_for_invalid_at.
|
| + Don't parse `@output file_name\n' or `@basename(...@)'. Instead,
|
| + recognize the start of a generalized `@directive(...@)' form and
|
| + start...
|
| + (SC_AT_DIRECTIVE_ARG): ... this new start condition to parse the
|
| + directive args (using the new obstack_for_string), to decode the
|
| + contained @ diagraphs, and to perform the directive. It recognizes
|
| + @basename(...@), @warn(...@), @complain(...@), @fatal(...@), and
|
| + @output(...@).
|
| + (SC_AT_DIRECTIVE_SKIP_WS): New start condition started by
|
| + SC_AT_DIRECTIVE_ARG to skip whitespace after the argument delimiter,
|
| + `@,'.
|
| + (scan_skel): Initialize obstack_for_string on the first call.
|
| + (skel_scanner_free): New function to free obstack_for_string.
|
| + * tests/input.at (Reject bad %code qualifiers): Update test output.
|
| +
|
| +2007-01-04 Joel E. Denny <jdenny@ces.clemson.edu>
|
| +
|
| + Consolidate the 4 prologue alternative directives (%code, %requires,
|
| + %provides, and %code-top) into a single %code directive with an
|
| + optional qualifier field. Discussed at
|
| + <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00012.html>.
|
| + * NEWS (2.3a+): Rewrite the existing entry for the prologue
|
| + alternatives.
|
| + * doc/bison.texinfo (Prologue Alternatives): Update.
|
| + (Decl Summary): Update to %code "requires" and %code "provides".
|
| + (Calc++ Parser): Update to %code "requires".
|
| + (Table of Symbols): Remove entries for %requires, %provides, and
|
| + %code-top. Rewrite %code entry, and add a %code "QUALIFIER" entry.
|
| + * data/bison.m4 (b4_user_provides, b4_user_requires): Remove as these
|
| + are replaced by b4_percent_code_provides and b4_percent_code_requires,
|
| + which are skeleton-specific.
|
| + (b4_check_percent_code_qualifiers): New. A skeleton can use this to
|
| + declare what %code qualifiers it supports and to complain if any other
|
| + qualifiers were used in the grammar.
|
| + * data/glr.cc: Update to use b4_user_code([b4_percent_code_requires])
|
| + and b4_user_code([b4_percent_code_provides]) in place of
|
| + b4_user_requires and b4_user_provides.
|
| + * data/glr.c, data/lalr1.cc, data/push.c, data/yacc.c: Likewise.
|
| + Add b4_user_code([b4_percent_code_top]) and
|
| + b4_user_code([b4_percent_code]).
|
| + Invoke b4_check_percent_code_qualifiers.
|
| + * src/parse-gram.y (PERCENT_CODE_TOP, PERCENT_PROVIDES,
|
| + PERCENT_REQUIRES): Remove.
|
| + (grammar_declaration): Remove RHS's for %code-top, %provides, and
|
| + %requires. Rewrite the %code RHS as the unqualified form defining the
|
| + muscle b4_percent_code. Add another RHS for the qualified %code form,
|
| + which defines muscles of the form b4_percent_code_QUALIFIER and the
|
| + b4_used_percent_code_qualifiers muscle.
|
| + * src/scan-gram.l (PERCENT_CODE_TOP, PERCENT_PROVIDES,
|

|
| + * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update to use

|
| +2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
|
| +
|
| + Use the new code_props interface for destructors and printers.
|
| + * src/symtab.h (symbol, semantic_type): Remove destructor_location and
|
| + printer_location members, and change the type of the destructor and
|
| + printer members to code_props.
|
| + (symbol_destructor_set, symbol_destructor_get, symbol_printer_set,

|
| + semantic_type_printer_set, default_tagged_destructor_set,
|
| + default_tagless_destructor_set, default_tagged_printer_set,
|
| + default_tagless_printer_set): Use code_props in arguments and return
|
| + types in place of char const * and location.
|
| + (symbol_destructor_location_get, symbol_printer_location_get): Remove
|
| + since the locations are now contained in the return of
|
| + symbol_destructor_get and symbol_printer_get.
|
| + * src/output.c (symbol_destructors_output, symbol_printers_output):
|
| + Replace with...
|
| + (symbol_code_props_output): ... this to eliminate duplicate code.
|
| + (output_skeleton): Update to use symbol_code_props_output.
|
| + * src/reader.c (symbol_should_be_used): Update use of
|
| + symbol_destructor_get.
|
| + * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
|
| + Update uses of the various _destructor_set and _printer_set functions.
|
| + * src/symtab.c: (default_tagged_destructor_location,
|
| + default_tagless_destructor_location, default_tagged_printer_location,
|
| + default_tagless_printer_location): Remove since we...
|

|
| + default_tagged_printer, default_tagless_printer): ... change the type
|
| + of these to code_props.

| + code_props members.
|
| + (symbol_print): Use SYMBOL_CODE_PRINT.
|
| +
|
| +2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
|
| +
|
| + Use the new code_props interface for rule actions.
|
| + * src/symlist.h (symbol_list): Replace action, action_location, and

|
| + (translate_rule_action): Remove, no longer used.

|
| +
|
| +2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
|
| +
|
| + Use the new code_props interface in parse-gram.y.
|
| + * src/parse-gram.y (prologue_declaration, braceless, epilogue.opt):
|
| + Update all uses of translate_* functions to use the new code_props
|
| + interface and to use gram_scanner_last_string_free and
|
| + code_scanner_last_string_free where possible.
|
| + (grammar_declaration): symbol_list_destructor_set and
|
| + symbol_list_printer_set now perform the translation, so don't do it
|
| + here. Use gram_scanner_last_string_free where possible.
|
| + * src/scan-code.h, src/scan-code.l (translate_symbol_action,
|
| + translate_code): Remove, no longer used.
|
| + * src/symlist.h, src/symlist.c (symbol_list_destructor_set,
|
| + symbol_list_printer_set): Perform code translation here rather than
|
| + depending on the caller to do so.
|
| +
|
| + * src/symlist.h (struct symbol_list): Correct some documentation typos.
|
| + * src/scan-gram.h (gram_last_string): Remove declaration.

|
| +
|
| +2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
|
| +
|
| + Encapsulate code properties and related functionality for the various
|
| + destructors, printers, and actions into a code_props structure and
|
| + interface. This patch merely implements code_props in scan-code.h and
|
| + scan-code.l. Future patches will rewrite other modules to use it.
|
| + Discussed starting at
|
| + <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00020.html>.
|
| + * src/location.h (EMPTY_LOCATION_INIT): Define so that it's easier to
|
| + consistently initialize const structs that have an empty location
|
| + field.
|
| + * src/location.c (empty_location): Initialize with EMPTY_LOCATION_INIT
|
| + to ensure consistency.
|
| + * src/scan-code.h (code_props): New structure.
|
| + (code_props_none_init, CODE_PROPS_NONE_INIT, code_props_none): New
|
| + function, macro, and const global variable for initializing a
|
| + code_props with no code.
|
| + (code_props_plain_init, code_props_symbol_action_init,
|
| + code_props_rule_action_init, code_props_translate_code): The rest of
|
| + the new code_props functional interface. Among other things, the init
|
| + functions set the code_props kind field so that
|
| + code_props_translate_code will know whether to behave like
|
| + translate_symbol_action, translate_rule_action, or translate_code.
|
| + These old translate functions must remain until all other modules are
|
| + updated to use the new code_props interface.
|
| + (code_scanner_last_string_free): New function similar to
|
| + gram_scanner_last_string_free.
|
| + (code_scanner_free): Add documentation.
|
| + * src/scan-code.l: Implement the new interface.
|
| + (code_lex): Make it static, add a code_props* argument, and remove the
|
| + rule argument.
|
| + (last_string): New static global similar to the one in scan-gram.l.
|
| + (SC_RULE_ACTION): Update to use the code_props* argument to code_lex
|
| + instead of rule.
|
| + (SC_SYMBOL_ACTION): For $$, set the is_value_used member of the
|
| + code_props since Bison may one day use this information for destructors
|
| + and printers.
|
| + (<*><<EOF>>): Use STRING_FINISH so that last_string is set.
|
| + (handle_action_dollar): Use symbol_list_n_get and set used flag
|
| + directly since symbol_list_n_used_set is removed.
|
| + (translate_action): Add a code_props* argument and remove the rule,
|
| + action, and location arguments. Pass the code_props* on to code_lex.
|
| + (translate_rule_action, translate_symbol_action, translate_code):
|
| + Rewrite as wrappers around the new code_props interface.
|
| + * src/symlist.h, src/symlist.c (symbol_list_n_used_set): Remove since
|
| + it would eventually need to break the encapsulation of code_props.
|
| +
|
| +2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
|
| +
|
| + * etc/.cvsignore: New.
|
| +
|
| +2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
|
| +
|
| + Add maintainer-push-check to run maintainer-check using push parsing in
|
| + place of pull parsing where available.
|
| + * Makefile.am (maintainer-push-check): New.
|
| + * data/bison.m4 (b4_use_push_for_pull_if): New.
|
| + * data/push.c: Redefine b4_push_if and b4_use_push_for_pull_if
|
| + appropriately based on their existing values.
|
| + (yypush_parse): Don't print push-parser-specific diagnostics if push
|
| + parsing is being used in place of pull parsing.
|
| + * data/yacc.c: If push parsing should replace pull parsing, redirect to
|
| + push.c.
|
| + * src/output.c (prepare): Check BISON_USE_PUSH_FOR_PULL environment
|
| + variable, and insert b4_use_push_for_pull_flag into muscles.
|
| + * tests/Makefile.am (maintainer-push-check): New.
|
| +
|
| +2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
|
| +
|
| + * data/push.c (yypush_parse): Set yynew = 1 at the end of a parse
|
| + (whether successful or failed) so that yypush_parse can be invoked
|
| + again to start a new parse using the same yypstate.
|
| + * tests/torture.at (AT_DATA_STACK_TORTURE): For push mode, extend to
|
| + check multiple yypull_parse invocations on the same yypstate. For pull
|
| + mode, extend to check multiple yyparse invocations.
|
| + (Exploding the Stack Size with Alloca): Extend to try with
|
| + %push-pull-parser.
|
| + (Exploding the Stack Size with Malloc): Likewise.
|
| +
|
| + * tests/calc.at (Simple LALR Calculator): Don't specify
|
| + %skeleton "push.c" since %push-pull-parser implies that now.
|
| + * tests/headers.at (export YYLTYPE): Don't check for the push
|
| + declarations. Otherwise, this test case can't be used to see if push
|
| + mode can truly emulate pull mode.
|
| + * tests/input.at (Torturing the Scanner): Likewise.
|
| + * tests/local.at (AT_YACC_OR_PUSH_IF, AT_PUSH_IF): Remove.
|
| + (AT_YYERROR_SEES_LOC_IF): Rather than AT_YACC_OR_PUSH_IF, use
|
| + AT_YACC_IF, which now includes the case of push mode since %skeleton
|
| + need not be used for push mode. This will be more intuitive once
|
| + push.c is renamed to yacc.c.
|
| +
|
| +2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
|
| +
|
| + For push mode, convert yyparse from a macro to a function, invoke yylex
|
| + instead of passing a yylexp argument to yypull_parse, and don't
|
| + generate yypull_parse or yyparse unless %push-pull-parser is declared.
|
| + Discussed starting at
|
| + <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00163.html>.
|
| + * data/bison.m4 (b4_pull_if): New.
|
| + * data/c.m4 (b4_identification): Define YYPULL similar to YYPUSH.
|
| + * data/push.c: Improve M4 quoting a little.
|
| + (b4_generate_macro_args, b4_parenthesize): Remove.
|
| + (yyparse): If there's a b4_prefix, #define this to b4_prefix[parse]
|
| + any time a pull parser is requested.
|
| + Don't #define this as a wrapper around yypull_parse. Instead, when
|
| + both push and pull are requested, make it a function that does that
|
| + same thing.
|
| + (yypull_parse): If there's a b4_prefix, #define this to
|
| + b4_prefix[pull_parse] when both push and pull are requested.
|
| + Don't define this as a function unless both push and pull are
|
| + requested.
|
| + Remove the yylexp argument and hard-code yylex invocation instead.
|
| + * etc/bench.pl.in (bench_grammar): Use %push-pull-parser instead of
|
| + %push-parser.
|
| + * src/getargs.c (pull_parser): New global initialized to true.
|
| + * getargs.h (pull_parser): extern it.
|
| + * src/output.c (prepare): Insert pull_flag muscle.
|
| + * src/parse-gram.y (PERCENT_PUSH_PULL_PARSER): New token.

| + (prologue_declaration): Set both push_parser and pull_parser = true for
|
| + %push-pull-parser. Set push_parser = true and pull_parser = false for
|
| + %push-parser.
|
| + * src/scan-gram.l: Don't accept %push_parser as an alternative to
|
| + %push-parser since there's no backward-compatibility concern here.
|
| + Scan %push-pull-parser.
|
| + * tests/calc.at (Simple LALR(1) Calculator): Use %push-pull-parser
|
| + instead of %push-parser.
|
| + * tests/headers.at (export YYLTYPE): Make yylex static, and don't
|
| + prototype it in the module that calls yyparse.
|
| + * tests/input.at (Torturing the Scanner): Likewise.
|
| + * tests/local.at (AT_PUSH_IF): Check for %push-pull-parser as well.
|
| +
|
| +2006-12-26 Joel E. Denny <jdenny@ces.clemson.edu>
|
| +
|
| + Update etc/bench.pl. Optimize push mode a little (the yyn change
|
| + deserves most of the credit).
|
| + * Makefile.am (SUBDIRS): Add etc subdirectory.
|
| + * configure.ac (AC_CONFIG_FILES): Add etc/bench.pl and etc/Makefile.
|
| + * data/push.c (b4_declare_parser_state_variables): Move yyn, yyresult,
|
| + yytoken, yyval, and yyloc declarations to...
|
| + (yyparse or yypush_parse): ... here to improve performance. For
|
| + yypush_parse invocations after the first, be sure to assign yyn its old
|
| + value again.
|
| + (yypstate_new): Don't bother initializing the yyresult field since the
|
| + initial value isn't used.
|
| + (yyn, yyresult, yytoken, yyval, yyloc): For each NAME in this list,
|
| + remove the #define that, in push mode, set it to yyps->NAME.
|
| + * etc/Makefile.am: New.
|
| + * etc/bench.pl: Remove and build it instead from...
|
| + * etc/bench.pl.in: ... this new file. Use @abs_top_builddir@ to invoke
|
| + "tests/bison" from the build directory by default rather than just
|
| + invoking "bison" from $PATH.
|
| + (calc_grammar): Update push parser code: don't declare yylval globally,
|
| + don't define yyparse_wrapper, and don't #define yyparse.
|
| + (bench_grammar): Update to check all working combinations of yacc.c,
|
| + push.c, impure, pure, pull, and push.
|
| +
|
| +2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
|
| +
|
| + For push mode, add pull wrappers around yypush_parse.
|
| + * data/push.c: (b4_generate_macro_args, b4_parenthesize): New macros.
|
| + (yypull_parse): New function wrapping yypush_parse.
|
| + (yyparse): New #define wrapping yypull_parse.
|
| + * tests/calc.at (_AT_DATA_CALC_Y): Call yyparse even when %push-parser
|
| + is declared.
|
| + * tests/headers.at (export YYLTYPE): Make yylex global. For push mode,
|
| + prototype yylex in the module that calls yyparse, and don't prototype
|
| + yyparse there. Otherwise, the yyparse expansion won't compile.
|
| + * tests/input.at (Torturing the Scanner): Likewise.
|
| +
|
| +2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
|
| +
|
| + Enable push parsers to operate in impure mode. Thus, %push-parser no
|
| + longer implies %pure-parser. The point of this change is to move
|
| + towards being able to test the push parser code by running the entire
|
| + test suite as if %push-parser had been declared.
|
| + * data/push.c (yypush_parse): For impure mode, remove the
|
| + yypushed_char, yypushed_val, and yypushed_loc arguments.
|
| + Instead, declare these as local variables initialized to the global
|
| + yychar, yylval, and yylloc.
|
| + For the first yypush_parse invocation only, restore the initial values
|
| + of these global variables when it's time to read a token since they
|
| + have been overwritten.
|
| + * src/parse-gram.y (prologue_declaration): Don't set pure_parser for
|
| + %push-parser.
|
| + * tests/calc.at (Simple LALR(1) Calculator): Always declare
|
| + %pure-parser along with %push-parser since this test case was designed
|
| + for pure push parsers.
|
| + * tests/local.at (AT_PURE_OR_PUSH_IF): Remove unused.
|
| + (AT_YACC_OR_PUSH_IF): New.
|
| + (AT_YYERROR_SEES_LOC_IF): Fix enough that the test suite passes, but
|
| + add a note that it's still wrong for some cases (as it has been for a
|
| + while).
|
| + (AT_PURE_LEX_IF): Use AT_PURE_IF instead of AT_PURE_OR_PUSH_IF since
|
| + %push-parser no longer implies %pure-parser.
|
| +
|
| +2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
|
| +
|
| + Remove some unnecessary differences between the pull parser code and
|
| + the push parser code. This patch enables yynerrs in push mode.
|
| + * data/push.c: Reformat M4 a little.
|
| + (b4_yyerror_range): Remove and convert all uses to just yyerror_range.
|
| + (b4_declare_scanner_communication_variables): Don't omit yynerrs just
|
| + because push mode is on. Instead, if pure mode is on, move yynerrs
|
| + to...
|
| + (b4_declare_parser_state_variables): ... here.
|
| + (yynerrs, yyerror_range): For push mode, #define each NAME in this list
|
| + to yyps->NAME so it can be used in yypush_parse.
|
| + (yypush_parse): Don't omit uses of yynerrs in push mode.
|
| +
|
| +2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
|
| +
|
| + Fix bug such that the first pushed token's value and location are
|
| + sometimes overwritten (sometimes by %initial-action) before being used.
|
| + * data/push.c (yypush_parse): Rename arguments yynchar, yynlval, and
|
| + yynlloc to yypushed_char, yypushed_val, and yypushed_loc for clarity.
|
| + For the first yypush_parse invocation, initialize yychar to YYEMPTY to
|
| + more closely mimic the pull parser logic.
|
| + Don't copy the pushed token to yychar, yylval, and yylloc until it's
|
| + time to read a token, which is after any initialization of yylval and
|
| + yylloc.
|
| + (gottoken): Rename label to...
|
| + (yyread_pushed_token): ... for clarity and to avoid infringing on the
|
| + user namespace.
|
| +
|
| +2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
|
| +
|
| + Rearrange initialization of the parser state variables so that the
|
| + skeleton doesn't have to have a copy for pull mode and another for push
|
| + mode. This patch also fixes at least a bug such that yylloc was not
|
| + initialized (with b4_location_initial_line and
|
| + b4_location_initial_column) upon calling yypush_parse. However, that
|
| + initialization now overwrites the first token's location;
|
| + %initial-action assigning @$ already did the same thing, and both bugs
|
| + will be fixed in a later patch.
|
| + * data/push.c (b4_yyssa): Remove and convert all uses to just yyssa.
|
| + (b4_declare_parser_state_variables): Remove initialization of yytoken,
|
| + yyss, yyvs, yyls, and yystacksize.
|
| + (yypstate_new): Remove initialization of some yypstate fields: yystate,
|
| + yyerrstatus, yytoken, yyss, yyvs, yyls, yystacksize, yyssp, yyvsp, and
|
| + yylsp.
|
| + (yyssa, yyvsa, yylsa): For push mode, #define each NAME in this list to
|
| + yyps->NAME so it can be used in yypush_parse.
|
| + (yyparse or yypush_parse): For yypush_parse, don't print the
|
| + "Starting parse" diagnostic for invocations after the first.
|
| + Add initialization of yytoken, yyss, yyvs, yyls, and yystacksize; for
|
| + yypush_parse, only do it for the first invocation.
|
| + Allow yystate, yyerrstatus, yyssp, yyvsp, yylsp, and yylloc
|
| + initialization to occur in yypush_parse but only on the first
|
| + invocation.
|
| +
|
| +2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
|
| +
|
| + * data/push.c: Add CPP guards around push parser declarations in both
|
| + the header and the code file.
|
| + In the code file, move the push parser declarations to the same place
|
| + they appear in the header file.
|
| + Clean up the M4 some, especially the inconsistent underquoting in
|
| + some b4_c_function_def and b4_c_function_decl uses.
|
| +
|
| +2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
|
| +
|
| + Encapsulate the push parser state variables into an M4 macro so the
|
| + push skeleton doesn't have to list them again for pull mode's yyparse.
|
| + For push mode, remove yypush_parse's local equivalents of these
|
| + variables to eliminate unnecessary copying between the two sets at
|
| + run-time. This patch also fixes at least a bug related to multiple
|
| + %initial-action invocations in push mode.
|
| + * data/push.c (b4_declare_parser_variables): Rename to...
|
| + (b4_declare_scanner_communication_variables): ... this for clarity and
|
| + update both uses.
|
| + (b4_declare_yyparse_variables): Remove and move its contents to the one
|
| + spot where it was invoked.
|
| + (b4_declare_parser_state_variables): New macro containing the parser
|
| + state variables required by push mode.
|
| + (struct yypstate): Replace all fields but yynew with
|
| + b4_declare_parser_state_variables.
|
| + (yystate, yyn, yyresult, yyerrstatus, yytoken, yyss, yyssp, yyvs,
|
| + yyvsp, yyls, yylsp, yystacksize, yyval, yyloc): For push mode, #define
|
| + each NAME in this list to yyps->NAME so it can be used in yypush_parse.
|
| + (yyparse or yypush_parse): For yyparse in pull mode, replace local
|
| + parser state variable declarations with
|
| + b4_declare_parser_state_variables.
|
| + Don't initialize parser state variables when calling yypush_parse since
|
| + yypstate_new already does that.
|
| + Invoke the user's initial action only upon the first yypush_parse
|
| + invocation.
|
| + Remove all code that copies between the local parser state variables
|
| + and the yypstate.
|
| +
|
| +2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
|
| +
|
| + * data/push.c (union yyalloc): Rename yyss, yyvs, and yyls fields to
|
| + prevent a name collision in a future patch where these names will
|
| + sometimes be #define'd.
|
| + (YYSTACK_RELOCATE): Add an argument to select a union yyalloc field
|
| + since it no longer has the same name as the existing argument.
|
| + (yyparse or yypush_parse): Update all uses of YYSTACK_RELOCATE.

|

|
| + that the argument is case-insensitive, and there's no `=' here.
|
| + For the %skeleton entry, mention that %language is better.
|
| + (Bison Options): Likewise for --language and --skeleton. Move the

|
| + (C++ Bison Interface): Don't use the word skeleton. Don't explain the

|
| + (Calc++ Parser): Use `%require "@value{VERSION}"' rather than
|
| + `%require "2.3b"' so that the example is always up-to-date.
|
| + (Table of Symbols): Add entries for %language and %skeleton.
|
| + * examples/extexi (normalize): Instead of replacing every %require

|
| + * examples/calc++/Makefile.am ($(calc_extracted)): Use `$(VERSION)'

|
| + Also, omit trailing white space.
|
| +
|
| + * bootstrap: Sync from coreutils.

|

|

|
| +
|
| +2006-12-12 Joel E. Denny <jdenny@ces.clemson.edu>
|
| +
|
| + * tests/testsuite.at (AT_CHECK): When checking if $1 starts with
|
| + `bison ', use m4_index instead of m4_substr since chopping up a string
|
| + containing M4-special characters causes problems here.
|
| +
|
| + Fix a couple of bugs related to special characters in user-specified
|
| + file names, and make it easier for skeletons to compute output file
|
| + names with the same file name prefix as Bison-computed output file
|
| + names.
|
| + * data/glr.cc, data/push.c, data/yacc.c: In @output, use
|
| + b4_parser_file_name and b4_spec_defines_file instead of
|
| + @output_parser_name@ and @output_header_name@, which are now redundant.
|
| + * data/glr.c, data/lalr1.cc: Likewise. Also, in header #include's, use
|
| + b4_parser_file_name, b4_spec_defines_file, and the new
|
| + @basename(FILENAME@) instead of @output_parser_name@ and
|
| + @output_header_name@, which inappropriately escaped the file names as
|
| + C string literals.
|
| + * src/files.c (all_but_ext): Remove static qualifier.
|
| + (compute_output_file_names): Move `free (all_but_ext)' to...
|
| + (output_file_names_free): ... here since all_but_ext is needed later.
|
| + * src/files.h (all_but_ext): Extern.
|
| + * src/muscle_tab.h (MUSCLE_INSERT_STRING_RAW): New macro that does
|
| + exactly what MUSCLE_INSERT_STRING used to do.
|
| + (MUSCLE_INSERT_STRING): Use MUSCLE_OBSTACK_SGROW so that M4-special
|
| + characters are escaped properly.
|
| + * src/output.c (prepare): Define muscle file_name_all_but_ext as
|
| + all_but_ext.
|
| + For pkgdatadir muscle, maintain previous functionality by using
|
| + MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem
|
| + is that b4_pkgdatadir is used inside m4_include in the skeletons, so
|
| + digraphs would never be expanded. Hopefully no one has M4-special
|
| + characters in his Bison installation path.
|
| + * src/scan-skel.l: Don't parse @output_header_name@ and
|
| + @output_parser_name@ anymore since they're now redundant.
|
| + In @output, use decode_at_digraphs.
|
| + Parse a new @basename command that invokes last_component.

|
| + * tests/testsuite.at (AT_CHECK): Redefine so that running Bison and

|
| +2006-10-12 Paul Eggert <eggert@cs.ucla.edu>

|
| + 2006-09-23 Jim Meyering <jim@meyering.net>
|

| +
|
| + 2006-09-18 Paul Eggert <eggert@cs.ucla.edu>
|
| +
|
| + * bootstrap (symlink_to_gnulib): New function.
|
| + (cp_mark_as_generated): Use it, to prefer symlinks-to-gnulib
|
| + to copies-of-gnulib.
|
| + (cp_mark_as_generated, slurp, gnulib_files):
|
| + Avoid making a copy if it's the same as the old version.
|
| + (gnulib_files): Add support for this variable (used by Bison).
|
| +
|
| +2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
|
| +
|
| + * src/getargs.c (usage): Rework to use conventions similar to
|
| + coreutils, to make translation a bit easier and the code a bit
|
| + smaller. Problem reported by Tim Van Holder.
|
| +
|
| +2006-09-15 Paul Eggert <eggert@cs.ucla.edu>
|
| +

|
| + (XGETTEXT_OPTIONS): Add complain, complain_at,

|
| + * configure.ac (AC_CONFIG_HEADERS): config.h is now in lib, not here.
|
| + (gl_USE_SYSTEM_EXTENSIONS): Remove; gl_EARLY now does this.
|
| + (gl_EARLY): Add.
|
| + (AM_STDBOOL_H): Remove; gl_INIT now dows this.
|
| + (gl_INIT): Add
|
| + (GNULIB_AUTOCONF_SNIPPET): Remove.
|
| + (AM_GNU_GETTEXT): Add; require formatstring macros since that's
|
| + the pickiest.
|
| + * lib/.cvsignore: Add inttypes_.h.
|
| + * lib/Makefile.am: Include gnulib.mk first so we can append to it.
|
| + (AM_CFLAGS): Add WERROR_CFLAGS, to be more like coreutils.
|
| + (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES): Remove
|
| + no-longer-necessary initializations.

| + * src/Makefile.am (DEFS): Remove, since configmake does this for us.
|
| + (AM_CPPFLAGS): Remove -I../lib, since Automake does that for us.
|
| + * src/system.h: Include inttypes.h unconditionally, now that we
|
| + use the inttypes module. Don't bother to include stdint.h, since
|
| + inttypes.h now does that for us.
|
| + (LOCALEDIR): Remove, now that we use the configmake module.
|
| + * src/getargs.c: Include configmake.h.
|
| + * src/main.c: Likewise.
|
| + * src/output.c: Likewise.
|
| + * tests/atlocal.in (CPPFLAGS): Include from $abs_top_builddir/lib,
|
| + not from $abs_top_builddir, since config.h moved.
|
| +
|
| +
|
| + Port to GCC 2.95. First two problems reported by Michael Deutschmann in
|
| + <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00018.html>.
|
| +
|
| + * src/parse-gram.y (symbol_declaration): Don't put statements
|
| + before declarations; it's not portable to C89.
|
| + * src/scan-code.l (handle_action_at): Likewise.
|
| +
|
| + * src/scan-code.l: Always initialize braces_level; the old code
|
| + left it uninitialized and therefore had undefined behavior.
|
| +
|
| + Don't attempt to redefine 'assert', since it runs afoul of
|
| + systems where standard headers (mistakenly) include <assert.h>.
|
| + Instead, define and use our own alternative, called 'aver'.
|
| + * src/reader.c: Don't include assert.h, since we no longer
|
| + use assert.
|
| + * src/scan-code.l: Likewise.
|
| + * src/system.h (assert): Remove, replacing with....
|
| + (aver): New function, taking a bool arg. All uses changed.
|

|
| +
|
| + * NEWS: Version 2.3a.
|
| + * configure.ac (AC_INIT): Likewise.
|
| +
|
| + * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Remove
|
| + "#define YYSTYPE int" that caused "make maintainer-check" to fail
|
| + due to header ordering dependencies. I don't know why the #define
|
| + was there.
|
| +
|
| + Fix glr.cc and lalr1.cc's use of YYDEBUG so that there's zero
|
| + runtime cost when YYDEBUG is not defined, and so that some tests
|
| + that used to fail now work. Problem and initial suggestion by
|
| + Paolo Bonzini.
|
| + * data/c++.m4 (b4_parse_param_cons): Omit leading ','.
|
| + * data/glr.cc (b4_parser_class_name):
|
| + Initialize yycdebug_ only if YYDEBUG. Also, initialize yydebug_.
|

|
| + (yycdebug_): Now defined only if YYDEBUG.
|

|
| +2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
|
| +
|
| + * data/glr.cc (YYERROR_VERBOSE, YYTOKEN_TABLE): Remove.
|
| + We don't need them in glr.cc, and glr.c defines them.
|
| + Defining YYERROR_VERBOSE to 0 here breaks glr.c, since glr.c
|
| + assumes that defining it to anything is the same as defining
|
| + it to 1. Problem reported by Paolo Bonzini.
|
| +
|
| +2006-09-12 Paolo Bonzini <bonzini@gnu.org> (tiny change)
|

|
| +
|
| + * data/glr.c (b4_shared_declarations): Put start-header first,
|
| + before any #includes that we generate, so that feature-test
|
| + macros work. Problem reported by Michael Deutschmann in
|
| + <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00004.html>.
|
| + * data/lalr1.cc: Likewise.
|
| + * doc/bison.texinfo (Prologue): Document that feature-test macros
|
| + should be defined before any Bison declarations.
|
| + * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Put defns
|
| + that depend on location.hh after, not before, Bison decls, since
|
| + we now include location.hh after the first user prologue.
|
| +
|
| + * doc/bison.texinfo (Calc++ Parser): Fix memory leak reported by
|
| + Sander Brandenburg in
|
| + <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00002.html>.
|
| + Also, fix minor white space and comment issues.
|
| + (Prologue): Mention that it's better to define feature-test macros
|
| + before Bison declarations. Problem reported by Michael Deutschmann.
|
| +
|
| + * README-cvs: Fix typo: "&" should be "&&". Problem reported
|
| + by Jim Meyering.
|
| + * m4/.cvsignore: Add argmatch.m4. Remove obstack.m4, strerror_r.m4.
|
| + This adjusts to recent gnulib changes.

|
| + the default.
|
| + * tests/actions.at (Per-type %printer and %destructor): New test case.
|
| + * tests/input.at (Default %printer and %destructor redeclared):

|
| + Require default %destructor/%printer to be declared using

|

|
| + Whether the default %destructor/%printer applies to a particular symbol
|
| + isn't a question of whether the user *declares* that symbol (in %token,
|
| + for example). It's a question of whether the user by any means
|
| + *defines* the symbol at all (by simply using a char token, for
|
| + example). $end is defined by Bison whereas any other token with token
|
| + number 0 is defined by the user. The error token is always defined by
|
| + Bison regardless of whether the user declares it with %token, but we
|
| + may one day let the user define error as a nonterminal instead.
|
| + * NEWS (2.3+): Say "user-defined" instead of "user-declared".
|
| + * doc/bison.texinfo (Freeing Discarded Symbols): Likewise, and document
|
| + the meaning of "user-defined".
|
| + * tests/actions.at (Default %printer and %destructor for user-declared
|
| + end token): Rename to...
|
| + (Default %printer and %destructor for user-defined end token): ...
|
| + this.
|
| +
|
| + * src/symtab.c (symbol_destructor_get, symbol_printer_get): In the
|
| + computation of whether to apply the default, don't maintain a list of
|
| + every Bison-defined symbol. Instead, just check for a first character
|
| + of '$', which a user symbol cannot have, and check for the error token.
|
| +
|
| +2006-08-21 Joel E. Denny <jdenny@ces.clemson.edu>
|
| +
|
| + Don't apply the default %destructor or %printer to the error token,
|
| + $undefined, or $accept. This change fits the general rule that the
|
| + default %destructor and %printer are only for user-declared symbols,
|
| + and it solves several difficulties that are described in the new test
|
| + cases listed below.
|
| + * src/symtab.c (symbol_destructor_get, symbol_printer_get): Implement.
|
| + * tests/actions.at (Default %printer and %destructor are not for error
|
| + or $undefined, Default %printer and %destructor are not for $accept):
|
| + New test cases.
|
| +
|
| +2006-08-19 Joel E. Denny <jdenny@ces.clemson.edu>
|
| +
|
| + Allow %start after the first rule.
|
| + * src/reader.c (grammar_current_rule_begin): Don't set the start symbol
|
| + when parsing the first rule.
|
| + (check_and_convert_grammar): Search for it here after all grammar
|
| + declarations have been parsed. Skip midrules, which have dummy LHS
|
| + nonterminals.
|
| + * src/symtab.c (symbol_is_dummy): New function.
|
| + * src/symtab.h (symbol_is_dummy): Declare it.
|
| + * tests/input.at (%start after first rule): New test.
|
| +
|
| +2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
|
| +
|
| + Redo some of the previous commit: add back the ability to use
|
| + non-aliased/undeclared string literals since it might be useful to
|
| + those declaring %token-table.
|
| + * src/reader.c (check_and_convert_grammar): Undo changes in previous
|
| + commit: don't worry about complaints from symbols_pack.
|
| + * src/symtab.c (symbol_new, symbol_class_set,
|
| + symbol_check_alias_consistency): Undo changes in previous commit: count
|
| + each string literal as a new symbol and token, assign it a symbol
|
| + number, and don't complain about non-aliased string literals.
|
| + (symbols_pack): Since symbol_make_alias still does not decrement symbol
|
| + and token counts but does still set aliased tokens to the same number,
|
| + symbol_pack_processor now leaves empty slots in the symbols array.
|
| + Remove those slots.
|
| + * tests/regression.at (Undeclared string literal): Remove test case
|
| + added in previous commit since non-aliased string literals are allowed
|
| + again.
|
| + (Characters Escapes, Web2c Actions): Undo changes in previous commit:
|
| + remove unnecessary string literal declarations.
|
| + * tests/sets.at (Firsts): Likewise.
|
| +
|
| +2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
|
| +
|
| + Don't allow an undeclared string literal, but allow a string literal to
|
| + be used before its declaration.
|
| + * src/reader.c (check_and_convert_grammar): Don't invoke packgram if
|
| + symbols_pack complained.
|
| + * src/symtab.c (symbol_new): Don't count a string literal as a new
|
| + symbol.
|
| + (symbol_class_set): Don't count a string literal as a new token, and
|
| + don't assign it a symbol number since symbol_make_alias does that.
|
| + (symbol_make_alias): It's not necessary to decrement the symbol and
|
| + token counts anymore. Don't assume that an alias declaration occurs
|
| + before any uses of the identifier or string, and thus don't assert that
|
| + one of them has the highest symbol number so far.
|
| + (symbol_check_alias_consistency): Complain if there's a string literal
|
| + that wasn't declared as an alias.
|
| + (symbols_pack): Bail if symbol_check_alias_consistency failed since
|
| + symbol_pack asserts that every token has been assigned a symbol number
|
| + although undeclared string literals have not.
|
| + * tests/regression.at (String alias declared after use, Undeclared
|
| + string literal): New test cases.
|
| + (Characters Escapes, Web2c Actions): Declare string literals as
|
| + aliases.
|
| + * tests/sets.at (Firsts): Likewise.
|
| +
|
| +2006-08-14 Joel E. Denny <jdenny@ces.clemson.edu>
|
| +
|
| + In the grammar scanner, STRING_FINISH unclosed constructs and return
|
| + them to the parser in order to improve error messages.
|
| + * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER,
|
| + SC_BRACED_CODE, SC_PROLOGUE): Implement.
|
| + * tests/input.at (Unclosed constructs): New test case.
|
| + * tests/regression.at (Invalid inputs): Update now that unclosed %{ is
|
| + seen.
|
| +
|
| + * src/scan-gram.h, src/scan-gram.l (gram_last_braced_code_loc): Remove
|
| + unused global.
|
| +
|
| +2006-08-13 Joel E. Denny <jdenny@ces.clemson.edu>
|
| +
|
| + Handle string aliases for character tokens correctly.
|
| + * src/symtab.c (symbol_user_token_number_set): If the token has an
|
| + alias, check and set its alias's user token number instead of its own,
|
| + which is set to indicate the alias. Previously, every occurrence of
|
| + the character token in the grammar overwrote that alias indicator with
|
| + the character code.
|
| + * tests/input.at (String aliases for character tokens): New test.
|
| +
|
| +2006-08-12 Joel E. Denny <jdenny@ces.clemson.edu>
|
| +
|
| + * src/parse-gram.y: Add `%expect 0' so we don't overlook conflicts.
|
| +
|
| +2006-08-11 Paul Eggert <eggert@cs.ucla.edu>
|
| +
|
| + * bootstrap: Put in need-ngettext argument to AM_GNU_GETTEXT,
|
| + to prevent failures when building on older platforms.
|
| + Check for autopoint failure.
|
| + Set XGETTEXT_OPTIONS to values that check for C format strings,
|
| + so that translators are warned about them (this also helps
|
| + prevent core dumps).
|
| +
|
| + * lib/subpipe.c (create_subpipe): Use new gnulib pipe_safer
|
| + function, since it simplifies our code a bit.
|
| +
|
| + * configure.ac (AC_ARG_ENABLE): Use -Wextra -Wno-sign-compare
|
| + rather than -W, so we don't get bogus warnings about sign comparisons.
|
| + Add -Wpointer-arith, since that warning is useful (it reports code
|
| + that does not conform to C89 and that some compilers reject).
|
| + * data/c.m4, data/glr.c, data/lalr1.cc, data/yacc.c: Undo latest change,
|
| + since it's no longer needed.
|
| +
|
| +2006-08-10 Joel E. Denny <jdenny@ces.clemson.edu>
|
| +
|
| + Clean up scanners a bit.
|
| + * src/flex-scanner.h (FLEX_NO_OBSTACK): New macro that blocks obstack
|
| + definitions so gcc won't warn when obstack_for_string is unused.
|
| + * src/scan-code.l: config.h and system.h are already #include'd by
|
| + scan-code-c.c, so get rid of them here.
|
| + * src/scan-gram.l: Likewise.
|
| + * src/scan-skel.l: Likewise, and use flex-scanner.h without obstack
|
| + definitions rather than duplicating the rest of it.
|
| + * src/scan-gram-c.c, scan-skel-c.c: #include "system.h".
|
| +
|
| +2006-08-09 Joel E. Denny <jdenny@ces.clemson.edu>
|
| +
|
| + Suppress signed/unsigned comparison warnings for yycheck.
|
| + * data/c.m4 (b4_safest_int_type): New macro.
|
| + * data/glr.c, data/lalr1.cc: Wherever you compare yycheck[i] against
|
| + a signed int type, cast it to b4_safest_int_type first.
|
| + * data/yacc.c: Likewise.
|
| + (b4_safest_int_type): Overwrite the one from c.m4 since b4_int_type is
|
| + also overwritten.
|
| +
|
| +2006-08-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> (tiny change)
|
| +
|
| + * doc/bison.texinfo: Fix some typos.
|
| +
|
| +2006-08-02 Paul Eggert <eggert@cs.ucla.edu>
|
| +
|
| + * m4/.cvsignore: Add inttypes_h.m4,lib-ld.m4, lib-prefix.m4,
|
| + po.m4, stdint_h.m4, uintmax_t.m4, ulonglong.m4, warning.m4.
|
| +
|
| + * bootstrap (gnulib_tool): Stop using --assume-autoconf;
|
| + the latest gnulib does this a different way.
|
| + (get_translations): Sharuzzaman Ahmat Raslan reported that the ms
|
| + translation was patched, so stop omitting it.
|
| +
|
| +2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
|
| +
|
| + Enable declaration of default %printer/%destructor. Make the parser
|
| + use these for all user-declared grammar symbols for which the user does
|
| + not declare a specific %printer/%destructor. Thus, the parser uses it
|
| + for token 0 if the user declares it but not if Bison generates it as
|
| + $end. Discussed starting at
|
| + <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>,
|
| + <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>,
|
| + and
|

|
| + * NEWS (2.3+): Mention.
|
| + * doc/bison.texinfo (Actions in Mid-Rule): It's no longer impossible to
|
| + declare a %destructor for a mid-rule's semantic value. It's just
|
| + impossible to declare one specific to it.
|
| + (Freeing Discarded Symbols): Mention that @$ can be used in %destructor
|
| + code. Describe default %destructor form.
|
| + * src/parse-gram.y (grammar_declaration): Parse default
|
| + %printer/%destructor declarations.
|
| + * src/output.c (symbol_destructors_output): Use symbol_destructor_get
|

|
| + and destructor_location members of struct symbol.
|
| + (symbol_printers_output): Likewise but for %printer's.
|
| + * src/reader.c (symbol_should_be_used): Likewise but for %destructor's
|
| + again.
|
| + * src/symtab.c (default_destructor, default_destructor_location,
|
| + default_printer, default_printer_location): New static global
|
| + variables to record the default %destructor and %printer.
|
| + (symbol_destructor_get, symbol_destructor_location_get,
|
| + symbol_printer_get, symbol_printer_location_get): New functions to
|
| + compute the appropriate %destructor and %printer for a symbol.
|
| + (default_destructor_set, default_printer_set): New functions to set the
|
| + default %destructor and %printer.
|
| + * src/symtab.h: Prototype all those new functions.
|
| + * tests/actions.at (Default %printer and %destructor): New test to
|
| + check that the right %printer and %destructor are called, that they're
|
| + not called for $end, and that $$ and @$ work correctly.
|
| + (Default %printer and %destructor for user-declared end token): New
|

|
| + a user-declared end token.
|
| + * tests/input.at (Default %printer and %destructor redeclared, Unused

|
| +
|
| +2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
|
| +
|
| + Clean up handling of %destructor for the end token (token 0).
|
| + Discussed starting at

|
| + and
|
| + <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00013.html>.
|
| +
|
| + Make the skeletons consistent in how they pop the end token and invoke
|
| + its %destructor.
|
| + * data/glr.c (yyrecoverSyntaxError, yyparse): Don't pop the start
|
| + state, which has token number 0, since this would invoke the
|
| + %destructor for the end token.
|
| + * data/lalr1.cc (yy::parser::parse): Don't check for the final state
|
| + until after shifting the end token, or else it won't be popped.
|
| + * data/yacc.c (yyparse): Likewise.
|
| +
|
| + * data/glr.c (yyparse): Clear the lookahead after shifting it even when
|
| + it's the end token. Upon termination, destroy an unshifted lookahead
|
| + even when it's the end token.
|
| + * data/lalr1.cc (yy::parser::parse): Likewise.
|
| + * data/yacc.c (yyparse): Likewise.
|
| +
|
| + * src/reader.c (packgram): Don't check rule 0. This suppresses unused
|
| + value warnings for the end token when the user gives the end token a
|
| + %destructor.
|
| +
|
| + * tests/actions.at (Printers and Destructors): Test all the above.
|
| +
|
| +2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
|

|
| + * bootstrap (gnulib-modules): Remove hard-locale, stdio-safer.
|
| + Add fopen-safer.
|
| + (gnulib_files): Add m4/warning.m4. Don't worry about files
|
| + overwritten by autopoint.
|
| + Replace gt_INTL_SUBDIR_CORE with an empty body in m4/gettext_gl.m4.
|
| + Suppress "id", "ms", "tr" translations for now, since gettext 0.15
|
| + rejects them.
|
| + Don't use autoreconf; instead, invoke autopoint etc. by hand,
|
| + so that we can remove the intl files at a better time.
|
| + (intl_files_to_remove): Remove aclocal.m4, since it gets
|
| + rebuilt anyway. Remove m4/inttypes_h.m4, m4/inttypes.m4,
|
| + m4/isc-posix.m4, m4/lib-ld.m4, m4/lib-prefix.m4, m4/po.m4,

|
| + Add m4/inttypes-h.m4, m4/lock.m4, m4/visibility.m4.
|
| + Remove datarootdir hack; no longer needed.
|
| + * configure.ac: Use gl_WARNING_CFLAGS rather than BISON_WARNING.
|
| + (AM_GNU_GETTEXT_VERSION): Bump from 0.12 to 0.15.
|
| + * lib/.cvsignore: Remove hard-locale.c, hard-locale.h, strdup.c,
|
| + strdup.h.
|
| + * m4/.cvsignore: Remove hard-locale.m4, strdup.m4.
|
| + * m4/warning.m4: Remove from CVS, since we now use gnulib's version.
|

|
| +2006-07-20 Paul Eggert <eggert@cs.ucla.edu>

|
| +
|

|
| + * src/muscle_tab.h (muscle_grow): Replace the header comments with

|
| +2006-07-13 Akim Demaille <akim@epita.fr>

|
| +
|
| +2006-07-12 Paul Eggert <eggert@cs.ucla.edu>
|
| +
|

| + * bootstrap (gnulib_modules): Add stdint.
|
| + Remove special case for m4/onceonly_2_57.m4, since gnulib-tool
|
| + no longer copies it.
|
| + (intl_files_to_remove): Remove m4/longlong.m4 and m4/wchar_t.m4,
|
| + since stdint needs the former and wcwidth (which is now required
|
| + by mbswidth) needs the latter.
|
| + Append 'datarootdir = @datarootdir@' to po/Makefile.in.in, to
|
| + work around a compatibility glitch between gettext 0.14.6 and
|
| + Autoconf 2.60.
|
| + * configure.ac (AC_PREREQ): Require Autoconf 2.60.
|
| + Do not check for uintptr_t, since new stdint module does the right
|
| + thing.
|
| + * lib/.cvsignore: Remove alloca.c, alloca.h, alloca_.h.
|
| + Add stdint.h, stdint_.h, wcwidth.h.

|
| + * src/files.c: Include <dirname.h> and <stdio-safer.h> in the
|

|
| + (file_name_split): Use last_component, not base_name, to adjust
|
| + to gnulib changes.
|
| + * src/parse-gram.h: Include <strverscmp.h> in the usual order
|
| + for ../lib/*.h files.
|
| + (YYTYPE_INT16, YYTYPE_INT8, YYTYPE_UINT16, YYTYPE_UINT8):
|
| + Define unconditionally, since we now assume the stdint module.
|
| + * src/scan-skel.l: Include <dirname.h>.
|
| + (BASE_QPUTS): Use last_component, not base_name.
|
| + * src/system.h: Include <unlocked-io.h> in the usual order
|
| + for ../lib/*.h files. Include <stdint.h> unconditionally,
|
| + since we now use the stdint module.
|
| + (uintptr_t): Declare if UINTPTR_MAX is not defined, not
|
| + HAVE_UINTPTR_T, since we now use the stdint module.
|
| + (base_name): Remove decl, since files now include <dirname.h>
|
| + to get the decl.

|
| + Don't mistake the type of $$ in a midrule to be that of its parent

|
| + * src/reader.c (grammar_current_rule_end): Don't invoke
|

|
| + parsed yet.
|
| + (grammar_midrule_action): Likewise.
|
| + Don't record whether the midrule's $$ has been used yet since actions

|
| + (grammar_current_rule_action_append): Don't translate the action yet
|

|
| + warnings about types for $$, $n, @$, and @n can't be reported yet.
|
| + (packgram): Translate the action and invoke grammar_rule_check now that

|
| + * src/scan-code.l (handle_action_dollar): Now that this is invoked
|
| + after parsing the entire grammar file, the symbol list here in the case
|
| + of a midrule is actually the midrule's empty RHS, so reference its

|

|
| + (symbol_list_length): Now that this is invoked after all rules have

|
| + * src/symlist.h (symbol_list.midrule_parent_rule,

|

| + implementing...
|
| + (Unused values): ... this old test case and...
|
| + (Unused values before symbol declarations): ... this new test case.

|
| +
|
| +2006-06-06 Akim Demaille <akim@epita.fr>
|
| +
|
| + Extract the parsing of user actions from the grammar scanner.
|
| + As a consequence, the relation between the grammar scanner and
|
| + parser is much simpler. We can also split "composite tokens" back
|
| + into simple tokens.
|
| + * src/gram.h (ITEM_NUMBER_MAX, RULE_NUMBER_MAX): New.
|
| + * src/scan-gram.l (add_column_width, adjust_location): Move to and
|
| + rename as...
|
| + * src/location.h, src/location.c (add_column_width)
|
| + (location_compute): these.

|
| + (location_print): Be robust to ending column being 0.

| + * src/location.h (boundary_set): New.
|
| + * src/main.c: Adjust to scanner_free being renamed as
|

|
| + (PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Remove the {...} part,
|
| + which is now, again, a separate token.
|
| + Adjust all dependencies.
|
| + Whereever actions with $ and @ are used, use translate_code.
|
| + (action): Remove this nonterminal which is now useless.
|
| + * src/reader.c: Include assert.h, scan-gram.h and scan-code.h.
|
| + (grammar_current_rule_action_append): Use translate_code.
|
| + (packgram): Bound check ruleno, itemno, and rule_length.
|

|
| + (last_string, last_braced_code_loc, max_left_semantic_context)
|
| + (scanner_initialize, scanner_free, scanner_last_string_free)
|
| + (gram_out, gram_lineno, YY_DECL_): Move to...
|
| + * src/scan-gram.h: this new file.
|
| + (YY_DECL): Rename as...

|
| + * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
|
| + (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
|
| + (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
|
| + Move these declarations, and...
|
| + (obstack_for_string, STRING_GROW, STRING_FINISH, STRING_FREE):
|
| + these to...
|
| + * src/flex-scanner.h: this new file.
|
| + * src/scan-gram.l (rule_length, rule_length_overflow)
|
| + (increment_rule_length): Remove.
|
| + (last_braced_code_loc): Rename as...
|
| + (gram_last_braced_code_loc): this.
|
| + Adjust to the changes of the parser.
|
| + Move all the handling of $ and @ into...
|
| + * src/scan-code.l: here.
|
| + * src/scan-gram.l (handle_dollar, handle_at): Remove.
|
| + (handle_action_dollar, handle_action_at): Move to...
|
| + * src/scan-code.l: here.
|
| + * src/Makefile.am (bison_SOURCES): Add flex-scanner.h,
|
| + scan-code.h, scan-code-c.c, scan-gram.h.
|
| + (EXTRA_bison_SOURCES): Add scan-code.l.
|
| + (BUILT_SOURCES): Add scan-code.c.

|
| +
|
| +2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
|
| +
|
| + * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
|
| + Use Akim's wording from
|
| + <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00056.html>.
|
| +
|
| +2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
|
| +
|
| + Between Bison releases, manually append `+' to the previous Bison
|
| + release number, and use that as a signal to automatically print the
|
| + ChangeLog's CVS Id keyword from --version. Discussed starting at
|
| + <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00028.html>.
|
| + * ChangeLog: Add Id header.
|
| + * configure.ac (AC_INIT): Append `+' to `2.3'.
|
| + * src/.cvsignore: Add revision.c.
|
| + * src/Makefile.am (bison_SOURCES): Add revision.c and revision.h.
|
| + (BUILT_SOURCES): Add revision.c.
|
| + (revision.c): New target rule. This file defines a new global variable
|
| + named revision. It initializes it with either the Id from ChangeLog
|
| + or, if VERSION doesn't contain `+', with the empty string.
|
| + * src/getargs.c (version): Print the value of revision.
|
| + * src/revision.h: Extern revision.
|
| +
|
| +2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
|
| +
|
| + * NEWS: Version 2.3.
|
| + * configure.ac (AC_INIT): Likewise.
|
| +
|
| +2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
|
| +
|
| + * data/glr.c (YYRECOVERING): Define to be a function-like macro
|
| + with no arguments, not as an object-like macro. This is for
|
| + compatibility with data/yacc.c. Problem reported by John P. Hartmann in
|
| + <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00059.html>.
|
| + * doc/bison.texinfo (Action Features, Error Recovery, Table of Symbols):
|
| + Document this.
|
| +
|
| +2006-05-30 Joel E. Denny <jdenny@ces.clemson.edu>
|
| +
|
| + * src/getargs.c (usage): Back out yesterday's modification of the
|
| + --help output so that we don't have to wait for translation before
|
| + releasing 2.3.
|
| +
|
| +2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
|
| +
|
| + * doc/bison.texinfo (Introduction): Don't say "GLR grammar".
|
| + Problem reported by Akim Demaille.
|
| +
|
| +2006-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
|
| +
|
| + * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
|
| +
|
| +2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
|
| +
|
| + * data/yacc.c (yy_reduce_print): Omit trailing white space in
|
| + generated source code. Problem reported by Frans Englich in
|
| + <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00049.html>.
|
| +
|
| +2006-05-22 Paul Eggert <eggert@cs.ucla.edu>
|
| +
|
| + * Makefile.maint (gzip_rsyncable, GZIP_ENV): Compute within the
|
| + shell, not within 'make', so that 'make' by an ordinary builder
|
| + (using GNU make) does not worry about configuring gzip. This also
|
| + works around a bug reported independently by Keith Thompson and by
|
| + Georg Schwarz, whereby gzip 1.2.4 --help would output usage on
|
| + stderr rather than stdout, messing up the build logs.
|
| +
|
| +2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
|
| +
|
| + * data/yacc.c (yyparse): Wrap the final return from yyparse inside YYID
|
| + to make sure that YYID will never be unused. This fixes a 'make
|
| + maintainer-check' failure caused by the recent changes to the 'Trivial
|
| + grammars' test case, which caused g++ 4.1.0 to complain that YYID was
|
| + not used.
|
| + * data/glr.c (yyparse): Wrap yyparse's return inside YYID just in case.
|
| +
|
| +2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
|
| +
|
| + * data/glr.c (yyresolveLocations): Remove bogus YYASSERT that the
|
| + state before an empty RHS is always resolved here. Only the location
|
| + of that state is guaranteed to be resolved, and that's enough. This
|
| + fixes the remaining bug reported by Derek M. Jones in
|
| + <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
|
| + * tests/glr-regression.at (Uninitialized location when reporting
|
| + ambiguity): Test the above case.
|
| + Also, the embedded comments in this test case claim it checks the case
|
| + of an empty RHS that has inherited the initial location. However, the
|
| + corresponding LHS was already resolved, so yyresolveLocations didn't
|
| + actually have reason to modify it. Fix this by forcing
|
| + nondeterministic operation at the beginning of the parse.
|
| +
|
| +2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
|
| +
|
| + * data/c.m4 (b4_yy_symbol_print_generate):
|
| + (b4_yy_symbol_print_generate): Use 'YYSTYPE const' rather than
|
| + 'const YYSTYPE', and similarly for YYLTYPE. This fixes one
|
| + of the bugs reported today by Derek M Jones in
|
| + <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
|
| + * doc/bison.texinfo (Value Type): Document that YYSTYPE must be
|
| + defined to be a type name without parens or brackets.
|
| + (Location Type): Similarly for YYLTYPE.
|
| + * tests/regression.at (Trivial grammars): Put in a test for this
|
| + bug that will be caught by 'make maintainer-check' (though not,
|
| + alas, by 'make check' unless your compiler is picky).
|
| +
|
| +2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
|
| +
|
| + * NEWS: Version 2.2.
|
| + * configure.ac (AC_INIT): Likewise.
|
| +
|
| +2006-05-17 Joel E. Denny <jdenny@ces.clemson.edu>
|
| +
|
| + * data/glr.c (yyreportTree): Make room in yystates for the state
|
| + preceding the RHS. This fixes the segmentation fault reported by Derek
|
| + M. Jones in
|
| + <http://lists.gnu.org/archive/html/help-bison/2006-05/msg00035.html>.
|
| + (yyreportTree, yypdumpstack): Subtract 1 from yyrule before printing
|
| + to the user. Reported for yyreportTree by Derek M. Jones later in the
|
| + same thread.
|
| + * THANKS: Add Derek M. Jones.
|
| + Update my email address.
|
| + Fix typo in Steve Murphy's name.
|
| +
|
| +2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
|
| +
|
| + * data/glr.c (yyreportSyntaxError): Fix off-by-one error in
|
| + checking against YYLAST that caused the parser to miss a potential
|
| + alternative in its diagnostic.
|
| + Problem reported by Maria Jose Moron Fernandez in
|
| + <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00024.html>.
|
| + * data/lalr1.cc (yysyntax_error_): Likewise.
|
| + * data/yacc.c (yysyntax_error): Likewise.
|
| + * tests/regression.at (_AT_DATA_DANCER_Y): Use static array for
|
| + tokens, in case we run into an older C compiler.
|
| + (_AT_DATA_EXPECT2_Y, AT_CHECK_EXPECT2): New macros.
|
| + Use them to check for the off-by-one error fixed above.
|
| +
|
| + * data/yacc.c (yytnamerr): Fix typo: local var should be of type
|
| + YYSIZE_T, not size_t.
|
| + * tests/regression.at (Trivial grammars): New test, to catch
|
| + the error fixed by the above patch.
|
| +
|
| +2006-05-14 Akim Demaille <akim@lrde.epita.fr>
|
| +
|
| + * doc/bison.texinfo (C++ Bison Interface): Clarify the naming
|
| + scheme.
|
| + Reported by Steve Murphy.
|
| +
|
| +2006-05-14 Akim Demaille <akim@lrde.epita.fr>
|
| +
|
| + * data/glr.cc, data/lalr1.cc: Using %defines is mandatory.
|
| + * data/glr.cc: b4_location_flag is now b4_locations_flag.
|
| +
|
| +2006-05-14 Akim Demaille <akim@lrde.epita.fr>
|
| +
|
| + Implement --trace=m4.
|
| + * src/getargs.c (trace_types, trace_args): Accept trace_m4.
|
| + * src/output.c (output_skeleton): When set, pass -dV to m4.
|
| +
|
| + Factor the handling of flags in m4.
|
| + * src/output.c (prepare): Rename the muscle names debug, defines,
|
| + error_verbose to debug_flag, defines_flag, error_verbose_flag.
|
| + * data/c.m4: Adjust.
|
| + (_b4_define_flag_if, b4_define_flag_if, b4_defines_if): New.
|
| + Use b4_define_flag_if to define other b4_FLAG_if macros.
|
| + (b4_location_if): As a consequence, rename as...
|
| + (b4_locations_if): this, for consistency.
|
| + Adjust all the skeletons.
|
| +
|
| +2006-05-14 Akim Demaille <akim@lrde.epita.fr>

|
| +
|
| +2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
|
| +
|
| + * data/c.m4 (b4_copyright): Put the special exception for Bison
|
| + skeletons here, so we don't have to put it in each skeleton. All
|
| + uses changed. Suggested by Akim Demaille. Also, wrap the
|
| + copyright notice, in case it is longer than 80 columns. Replace
|
| + comma by newline after title.
|
| +
|
| +2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
|
| +
|
| + * doc/bison.texinfo (Calc++ Scanner): The flex behavior is an

|
| +
|
| +2006-05-11 Akim Demaille <akim@lrde.epita.fr>

|
| + (yyresolveStates): Document the interface. Move all manipulation of a

|
| + Remove the yyvalp and yylocp parameters since they are always just
|
| + taken from the yys parameter. When reporting a discarded merged value
|
| + in debugging output, note that it is incompletely merged. Document the
|
| + interface.
|
| + (yyresolveAction): If resolving any of the RHS states fails, destroy
|
| + them all rather than leaking them. Thus, as long as user actions are
|

|
| + the RHS of a semantic option. Document the interface.

|
| + * data/glr.c (yyresolveValue): When merging semantic options, if at

|
| + (yyresolveStates): If a user action cuts the parse and thus
|
| + yyresolveValue fails, ignore the (unset) semantic value rather than
|
| + corrupting the yyGLRState, and empty the semantic options list since

|
| +
|
| + Use unlocked I/O for a minor performance improvement on hosts like
|
| + GNU/Linux and Solaris that support unlocked I/O. The basic idea
|
| + is to use the gnlib unlocked-io module, and to prefer putc and

|
| +
|
| +2005-08-24 Paul Eggert <eggert@cs.ucla.edu>
|
| +
|
| + * data/glr.c (yyrecoverSyntaxError, yyreturn):
|
| + Don't invoke destructor on unresolved entries.
|
| + * tests/glr-regression.at
|
| + (User destructor for unresolved GLR semantic value): New test case.
|
| + Problem reported by Joel E. Denny in:

|
| +2005-08-21 Paul Eggert <eggert@cs.ucla.edu>
|
| +
|
| + * lib/.cvsignore: Remove realloc.c, strncasecmp.c, xstrdup.c.
|
| + Add strnlen.c.
|
| + * m4/.cvsignore: Remove codeset.m4, gettext.m4, lib-ld.m4,
|
| + lib-prefix.m4, po.m4.
|
| +
|
| + * data/glr.c (yyreturn): Use "Cleanup:" rather than "Error:"
|
| + in yydestruct diagnostic, since it might not be an error.
|
| + Problem reported by Joel Denny near end of
|
| + <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
|
| + * data/lalr1.cc (yyerturn): Likewise.
|
| + * data/yacc.c (yyreturn): Likewise.
|
| + * tests/calc.at (_AT_CHECK_CALC_ERROR): Adjust to the above change.
|
| +
|
| + * src/files.c: Remove obsolete FIXME comment.
|
| +
|
| + * data/glr.c (YY_SYMBOL_PRINT): Append a newline, for consistency
|
| + with the other templates, and to fix bogus run-on messages such
|
| + as the one reported at the end of
|
| + <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
|
| + All callers changed to avoid the newline.
|
| + (yyprocessOneStack): Output two lines rather than one, to accommodate
|
| + the above change. This changes the debug output format slightly.
|
| +
|
| + * data/glr.c (yyresolveValue): Fix redundant parse tree problem
|
| + reported by Joel E. Denny in
|
| + <http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00004.html>
|
| + (trivial change).
|
| + * tests/glr-regression.at (Duplicate representation of merged trees):
|
| + New test, from Joel E. Denny in:
|
| + <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00013.html>.
|
| + * THANKS: Add Joel E. Denny.
|
| +
|

|
| +
|
| +2005-07-24 Paul Eggert <eggert@cs.ucla.edu>
|
| +
|
| + * NEWS: Version 2.0b.
|
| +
|
| + * Makefile.am (SUBDIRS): Put examples before tests, so that
|
| + "make check" doesn't finish with "All 1 tests passed".
|
| +
|
| + * tests/regression.at (Token definitions): Don't rely on
|
| + AT_PARSER_CHECK for data that contains backslashes. It currently
|
| + uses 'echo', and 'echo' isn't portable if its argument contains
|
| + backslashes. Problem found on OpenBSD 3.4. Also, do not assume
|
| + that the byte '\0xff' is not printable in the C locale; it is,
|
| + under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
|
| + not printable, so use '\0x81' to test.
|
| +
|
| + * data/glr.c (YYOPTIONAL_LOC): Define even if it's not a recent
|
| + version of GCC, since the macro is used with non-GCC compilers.
|
| +
|
| + Fix core dump reported by Pablo De Napoli in
|
| + <http://lists.gnu.org/archive/html/bug-bison/2005-07/msg00053.html>.
|
| + * tests/regression.at (Invalid inputs with {}): New test.
|
| + * src/parse-gram.y (token_name): Translate type before using
|
| + it as an index.
|
| +
|
| + * data/glr.c (ATTRIBUTE_UNUSED): Remove, since it infringes on
|
| + the user's name space. All uses changed to __attribute__
|
| + ((__unused__)).
|
| + (yyFail, yyMemoryExhausted, yyreportAmbiguity):
|
| + Add __attribute__ ((__noreturn__)).
|
| +
|
| + * etc/clcommit: Remove. We weren't using it, and it failed
|
| + "make maintainer-distcheck".
|
| + * Makefile.maint: Merge from coreutils.
|
| + (CVS_LIST, CVS_LIST_EXCEPT): New macros.
|
| + (syntax-check-rules): Change list of rules as described below.
|

|
| + (header_regexp, h_re): Remove.
|
| + (dd_c): New macro.
|
| + (sc_dd_max_sym_length, .re-list, news-date-check): New rules.
|
| + (my-distcheck): Use more-modern GCC flags.
|
| + (signatures, %.asc): Remove.
|
| + (rel-files, announcement): Remove signatures.
|
| + Restore old updating code, even though we don't use it, so
|
| + that we're the same as coreutils.
|
| + (alpha, beta, major): Depend on news-date-check.
|
| + Make the upload commands.
|
| +
|

| + * tests/sets.at: Likewise.
|
| +
|
| + * data/m4sugar/m4sugar.m4: Sync from Autoconf, except that
|
| + we comment out the Autoconf version number.
|
| + * doc/bison.texinfo (Calc++ Scanner): Don't use atoi, as
|
| + it's error-prone and "make maintainer-distcheck" rejects it.
|
| +
|
| + * lib/subpipe.c: Include <fcntl.h> without checking for HAVE_FCNTL_H.
|
| + Indent calls to "error" to pacify "make maintainer-distcheck",
|
| + when the calls are not intended to be translated.
|
| + * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't check for fcntl.h.
|
| +
|
| + * src/Makefile.am (DEFS): Use +=, to pacify
|
| + "make maintainer-distcheck".
|
| + (bison_SOURCES): Add scan-skel.h.
|
| + (sc_tight_scope): New rule, from coreutils.
|
| +
|

|
| + * src/getargs.h: Redo comments to pacify "make maintainer-distcheck".
|
| + * src/main.c (main): Cast bindtextdomain and textdomain calls to
|
| + void, to avoid warning when NLS is disabled.
|
| + * src/output.c: Include scan-skel.h.
|
| + (scan_skel): Remove decl, since scan-skel.h does this.
|
| + (output_skeleton):
|
| + Indent calls to "error" to pacify "make maintainer-distcheck".
|
| + * src/print_graph.c: Don't include <obstack.h>, as system.h does this.
|
| + * src/reader.h (gram_end, gram_lineno): New decls to pacify
|
| + "make maintainer-distcheck".
|
| + * src/scan-skel.l (skel_lex, skel_get_lineno, skel_get_in):
|
| + (skel_get_out, skel_get_leng, skel_get_text, skel_set_lineno):
|
| + (skel_set_in, skel_set_out, skel_get_debug, skel_set_debug):
|
| + (skel_lex_destroy, scan_skel): Move these decls to...
|

|
| + * src/uniqstr.c (uniqstr_assert):
|
| + Indent calls to "error" to pacify "make maintainer-distcheck".
|
| +
|
| + * tests/Makefile.am ($(srcdir)/package.m4): Use $(VAR),
|
| + not @VAR@.
|
| +
|
| + * tests/torture.at: Revamp to avoid misuse of atoi that
|
| + "make maintainer-distcheck" complained about.
|
| +
|
| + * examples/extexi (message): Don't print a message more than once,
|
| + and omit line-number decoration that makes Emacs compile think
|
| + that informative messages are worth worrying about.
|
| +
|
| +2005-07-22 Paul Eggert <eggert@cs.ucla.edu>
|
| +
|
| + * configure.ac: Update version number.
|
| +
|
| + * Makefile.am (SUBDIRS): Add examples; somehow this got removed
|
| + accidentally.
|
| + * examples/calc++/calc++-parser.yy: Remove from CVS, as it's
|
| + autogenerated by the maintainer.
|
| + * examples/calc++/.cvsignore: Add *.yy.
|
| +
|
| + * lib/bitset.c (bitset_alloc): Don't cast xcalloc result.
|
| + * lib/bitset_stats.c (bitset_stats_init): Likewise.
|
| + * lib/bitsetv.c (bitsetv_alloc): Likewise.
|
| +
|
| + * po/POTFILES.in: Add lib/xalloc-die.c; remove lib/xmalloc.c.
|
| +
|
| + * src/relation.c (relation_transpose): Rewrite to avoid bogus complaint
|
| + from maintainer-distcheck about casting the argument of 'free'.
|
| +
|
| + * NEWS: Mention recent yytname changes.
|
| + * THANKS: Add Anthony Heading, twlevo@xs4all.nl.
|
| +
|
| + * bootstrap: For translations that have not yet been upgraded to
|
| + the new runtime-po domain, prime the pump by extracting the
|
| + relevant strings from the obsolete translations. This code can be
|
| + removed once the bison-runtime domain has been translated by each
|
| + team.
|
| +
|
| + * src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names,
|
| + now that token names are already quoted.
|
| +
|
| + Fix problem reported by Anthony Heading.
|
| + * data/glr.c (YYTOKEN_TABLE): New macro.
|
| + (yytname): Define if YYTOKEN_TABLE.
|
| + * data/yacc.c (YYTOKEN_TABLE, yytname): Likewise.
|
| + * data/lalr1.cc (YYTOKEN_TABLE, yytname_): Likewise.
|
| + (YYERROR_VERBOSE): Define the same way the other skeletons do.
|
| + * src/output.c (prepare_symbols): Output token_table_flag.
|
| +
|
| +2005-07-21 Paul Eggert <eggert@cs.ucla.edu>
|
| +
|
| + * data/glr.c (yyinitGLRStack, yyreturn): Don't call malloc
|
| + again if the first call fails.
|
| +
|
| + * data/glr.c (yytnamerr): New function.
|
| + (yyreportSyntaxError): Use it to dequote most string literals.
|
| + * data/lalr1.c (yytname_): Renamed from yyname_, for compatibility
|
| + with other skeletons. All uses changed.
|
| + (yytnameerr_): New function.

| + (yyreport_syntax_error): Use it to dequote most string literals.
|
| + * data/yacc.c (yytnamerr): New function.
|

|
| + * doc/bison.texinfo (Decl Summary, Calling Convention):
|
| + Clarify quoting convention of yytname.
|
| + * src/output.c (prepare_symbols): Quote all names. This undoes
|
| + the 2005-04-17 change, which is now accomplished (mostly) via
|
| + changes in the parsers as described above.
|
| + * tests/regression.at (Token definitions, Web2c Actions):
|
| + Undo most 2005-04-17 change here, too.
|
| +
|
| +2005-07-20 Paul Eggert <eggert@cs.ucla.edu>
|
| +
|
| + Fix more problems reported by twlevo@xs4all.nl.
|
| + * tests/cxx-type.at: Don't pipe output of ./types through sed to
|
| + remove trailing spaces. This loses the exit status of ./types,
|
| + and isn't needed since ./types shouldn't be emitting trailing
|
| + spaces.
|
| + * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
|
| + as the stack isn't valid in that case.
|
| +
|
| + * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
|
| + (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
|
| + (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
|
| + Add declarations to pacify "gcc -Wmissing-prototypes" when flex 2.5.31
|
| + is used.
|
| + * src/scan-skel.l (skel_get_lineno, skel_get_in, skel_get_out):
|
| + (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
|
| + (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
|
| + Likewise.
|
| +
|
| + * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Work even with
|
| + overly-picky compilers that reject 'char *foo = "bar";'.
|
| +
|
| + * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
|
| + to FILE * parameter, not to stderr. This fixes a typo introduced
|
| + in the 2005-07-12 change.
|
| +
|
| + * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid
|
| + warnings from GCC 4.
|
| +
|
| + * data/glr.c (yyexpandGLRStack, yyaddDeferredAction, yyexpandGLRStack):
|
| + (yyglrShiftDefer, yysplitStack):
|
| + Remove unused parameters b4_pure_formals. All uses changed.

| + (yyglrShift): Remove unused parameters b4_user_formals.
|
| + All uses changed.
|
| + (yyglrReduce): Removed unused parameter yylocp. All uses changed.
|
| +
|
| +2005-07-18 Paul Eggert <eggert@cs.ucla.edu>
|
| +
|
| + Destructor cleanups and regularization among the three skeletons.
|
| + * NEWS: Document the behavior changes.
|
| + * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
|
| + stack before failing, as the cleanup code will do it for us now.
|
| + * data/lalr1.cc (yyerrlab): Likewise.
|
| + * data/glr.c (yyparse): Pop everything off the stack before
|
| + freeing it, so that destructors get called properly.
|
| + * data/lalr1.cc (yyreturn): Likewise.
|
| + * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
|
| + This is more consistent.
|
| + * doc/bison.texinfo (Destructor Decl): Mention more reasons
|
| + why destructors might be called. 1.875 -> 2.1.
|
| + (Destructor Decl, Decl Summary, Table of Symbols):
|
| + Some English-language cleanups for %destructor.
|
| + * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
|
| + Add output line for destructor of start symbol.
|
| + * tests/calc.at (AT_CHECK_CALC): Add one to line counts,
|
| + because of that same extra output line.
|
| +
|
| + * NEWS: Document minor wording changes in diagnostics of
|
| + Bison-generated parsers.
|
| + * data/glr.c (yyMemoryExhausted): Renamed from yyStackOverflow.
|
| + Remove unused formals. All uses changed.
|
| + (yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous".
|
| + (yyparse): Rename yyoverflowlab to yyexhaustedlab.
|
| + * data/yacc.c (yyparse): "parser stack overflow" -> "memory exhausted".
|
| + Rename yyoverflowab to yyexhaustedlab.
|
| + When memory exhaustion occurs during syntax-error reporting,
|
| + report it separately rather than in a single diagnostic; this
|
| + eases translation.
|
| + * doc/bison.texinfo (Memory Management): Renamed from Stack Overflow.
|
| + (Memory Exhausted): Renamed from Parser Stack Overflow.
|
| + Revamp wording slightly to prefer "memory exhaustion".
|
| + * tests/actions.at: "parser stack overflow" -> "memory exhausted".
|
| +
|
| + * data/c.m4 (b4_yysymprint_generate): Use YYFPRINTF, not fprintf.
|
| +
|
| + Add i18n support to the GLR skeleton. Partially fix the C++
|
| + skeleton; a C++ expert needs to finish this. Remove debugging
|
| + msgids; there's little point to having them translated, since they
|
| + can be understood only by someone who can read the
|
| + (English-language) source code.
|
| +
|
| + Generate runtime-po/bison-runtime.pot automatically, so that we
|
| + don't have to worry about garbage getting in that file. We'll
|
| + make sure after the next official release that old msgids don't
|
| + get lost. See
|
| + <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
|
| +
|
| + * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
|
| + Now auto-generated.
|
| + * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
|
| + Fix typos in explanations of the runtime file.
|
| + * bootstrap: Change gettext keyword from YYI18N to YY_.
|
| + Use standard Makefile.in.in in runtime-po, since we'll arrange
|
| + for backward-compatible bison-runtime.po files in a different way.
|
| + * data/glr.c (YY_): New macro, from yacc.c.
|
| + (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
|
| + Translate messages intended for users.
|
| + (yyreportSyntaxError): Change "virtual memory" to "memory" to match
|
| + the wording in the other skeletons. We don't know that the memory
|
| + is virtual.
|
| + * data/lalr1.cc (YY_): Renamed from _. All uses changed.
|
| + Use same method that yacc.c uses.
|
| + Don't translate debugging messages.
|
| + (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
|
| + it doesn't work (yet), and requires C++ expertise to fix.
|
| + * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
|
| + Move defn to a more logical place, to be consistent with other
|
| + skeletons.
|
| + Don't translate debugging messages.
|
| + Don't assume line numbers fit in unsigned int; use unsigned long fmts.
|
| + * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
|
| + to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
|
| + * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.
|
| +
|
| + Fix yyerror / yylex test glitches noted by twlevo@xs4all.nl.
|
| + * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Have yyerror return
|
| + void, not int.
|
| + * tests/glr-regression.at (Badly Collapsed GLR States):
|
| + Likewise.
|
| + (Improper handling of embedded actions and dollar(-N) in GLR parsers):
|
| + yylex should return 0 at EOF rather than aborting.
|
| +
|
| + Improve tests for stack overflow in GLR parser.
|
| + Problem reported by twlevo@xs4all.nl.
|
| + * data/glr.c (struct yyGLRStack): Remove yyerrflag member.
|
| + All uses removed.
|
| + (yyStackOverflow): Just longjmp, but with value 2 so that caller
|
| + can handle the problem.
|
| + (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
|
| + (yyparse): New local variable yyresult to record the result.
|
| + Use result of setjmp to set it, rather than storing itinto
|
| + struct.
|
| + (yyDone): Remove label.
|
| + (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
|
| + to mimic yacc.c. Do not discard lookahead if it's EOF (possible
|
| + if YYABORT is used).
|
| + * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with
|
| + yyparse status; put status > 1 into diagnostic.
|
| + Check that status==2 works.
|
| + * tests/calc.at, tests/cxx-type.at, tests/glr-regression.at:
|
| + Use exit status 3 for failure to open (which shouldn't happen).
|
| +
|
| +2005-07-17 Paul Eggert <eggert@cs.ucla.edu>
|
| +
|
| + * tests/conflicts.at (%nonassoc and eof): Don't exit with status
|
| + 1 on syntax error; just let yyparse do its thing.
|
| + * tests/glr-regression.at (Badly Collapsed GLR States): Likewise.
|
| + * tests/torture.at (AT_DATA_STACK_TORTURE): Likewise.
|
| + (Exploding the Stack Size with Alloca):
|
| + (Exploding the Stack Size with Malloc):
|
| + Expect exit status 2, not 1, since the parser is supposed to blow
|
| + its stack. Problem reported by twlevo@xs4all.nl.
|
| +
|
| + * data/glr.c (yyparse): Don't assume that the initial calls
|
| + to YYMALLOC succeed; in that case, yyparse incorrectly returned 0.
|
| + Print a stack-overflow message and fail instead.
|
| + Initialize the line-number information before creating the stack,
|
| + so that the stack-overflow message can report line zero safely.

|
| +
|
| + Fix problems reported by twlevo@xs4all.nl.

|
| + * tests/glr-regression.at
|
| + (Improper handling of embedded actions and dollar(-N) in GLR parsers):
|
| + Add casts to pacify C++ compilers.
|
| + * tests/glr-regression.at (Improper merging of GLR delayed action
|
| + sets): Declare yylex before using it.
|
| + * tests/Makefile.am (maintainer-check-g++): Fix a stray
|
| + $(GXX) that escaped the renaming of GXX to CXX. Remove bogus
|
| + test for valgrind; valgrind is independent of g++.
|
| + (maintainer-check-posix): Add _POSIX2_VERSION=200112, to check
|
| + for compatibility with POSIX 1003.1-2001 (if running coreutils).

| + * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Port to stricter C++.
|
| + Use a destructor, so that we can expand the stack. Change
|
| + YYSTYPE to char * so that we can free it. Cast result of malloc.
|

|
| +2005-07-13 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
|

|
| +2005-07-13 Paul Eggert <eggert@cs.ucla.edu>

|

| +
|
| +2005-07-09 Paul Eggert <eggert@cs.ucla.edu>

|
| + * data/yacc.c (yyparse): Undo previous patch. Instead,

| + set yylsp[0] and yyvsp[0] only if the initial action
|
| + sets yylloc and yylval, respectively.
|
| +
|
| + * data/yacc.c (yyparse): In the initial action, set
|
| + yylsp[0] and yyvsp[0] rather than yylloc and yylval.
|
| + This avoids the use of undefined variables if the initial
|
| + action does not set yylloc and/or yylval.
|
| +
|
| +2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
|
| +
|
| + * examples/calc++/calc++-driver.cc, examples/calc++/calc++-driver.hh:
|
| + * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc:
|
| + Remove from CVS. These files are automatically generated.
|
| + * examples/extexi: Clarify that this file is now part of Bison,
|
| + not GNU M4, and that it works with any POSIX-compatible Awk.
|
| + * examples/calc++/Makefile.am (run_extexi): Remove; not used.
|
| + ($(calc_extracted)): Renamed from $(calc_sources_extracted),
|
| + so that we also get calc++-parser.yy. Geneate it.
|
| + Use $(AWK), not gawk, since any conforming Awk will do.
|
| + Put comment before action, since older 'make' can't handle comment
|
| + in action.
|
| + $(BUILT_SOURCES): List all built sources, not just some of them.
|
| + $(MAINTAINERCLEANFILES): Remove *.stamp, and all built sources.
|
| + $($(srcdir)/calc++-parser.stamp): Work even if POSIXLY_CORRECT.
|
| + $($(calc_sources_generated)): Remove unnecessary test for existence

|
| + (calc_extracted): List $(srcdir)/calc++-parser.yy, not
|
| + calc++-parser.yy.
|
| + * examples/.cvsignore, examples/calc++/.cvsignore: New files.

|
| +
|
| +2005-07-05 Paul Eggert <eggert@cs.ucla.edu>
|
| +
|
| + * data/glr.c (yyFail): Drastically simplify; since the format argument
|
| + never had any % directives, we can simply pass it to yyerror.
|
| + (yyparse): Use "t a; a=b;" rather than "t a = b;" when a will
|
| + be modified later, as that is the usual style in glr.c.
|
| + Problems reported by Paul Hilfinger.
|
| +
|
| + Rewrite GLR parser to catch more buffer overrun, storage exhaustion,
|
| + and size overflow errors.
|
| + * data/glr.c: Include <stdio.h> etc. after user prolog, not before,
|
| + in case the user prolog sets feature-test macros like _GNU_SOURCE.
|
| + (YYSIZEMAX): New macro.
|
| + (yystpcpy): New function, taken from yacc.c.
|
| + (struct yyGLRStack.yyspaceLeft): Now size_t, not int.
|
| + (yyinitGLRStack, yyfreeGLRstack): Remove unnecessary forward decls,
|
| + so that we don't have to maintain their signatures.
|
| + (yyFail): Check for buffer overflow, by using vsnprintf rather
|
| + than vsprintf. Allocate a bigger buffer if possible.
|
| + Report an error if buffer allocation fails.
|
| + (yyStackOverflow): New function.
|
| + (yyinitStateSet, yyinitGLRStack): Return a boolean indicating whether
|
| + the initialization was successful. It might fail if storage was
|
| + exhausted.
|
| + (yyexpandGLRStack): Add more checks for storage allocation failure.
|
| + Use yyStackOverflow to report failures.
|
| + (yymarkStackDeleted, yyglrShift, yyglrShiftDefer, yydoAction):
|
| + (yysplitStack, yyprocessOneStack, yyparse, yypstack):
|
| + Don't assume stack number fits in int.
|
| + (yysplitStack): Check for storage allocation failure.
|
| + (yysplitStack, yyprocessOneStack): Add pure_formals, so that we
|
| + can print diagnostics on storage allocation failure. All callers
|
| + changed.
|
| + (yyresolveValue): Use yybool for boolean.
|
| + (yyreportSyntaxError): Check for size-calculation overflow.
|
| + This code is taken from yacc.c.
|
| + (yyparse): Check for storage allocation errors when allocating
|
| + the initial stack.
|
| +

| +
|
| + Extract calc++ from the documentation.
|
| + * doc/bison.texinfo (Calc++): Add the extraction marks.
|
| + * examples/extexi: New, from the aborted GNU Programming 2E.
|
| + Separate the different paragraph of a file with empty lines.

| + * examples/Makefile: Use it to extract the whole calc++ example.
|
| +
|
| +2005-06-24 Akim Demaille <akim@epita.fr>

|
| +
|
| + * data/yacc.c (malloc, free) [defined __cplusplus]: Wrap inside

|
| + which stems from the 2005-05-27 patch.
|
| +
|
| +2005-06-06 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
|
| +
|
| + * data/glr.c: Modify treatment of unused parameters to permit use

|

|
| +2005-05-30 Paul Eggert <eggert@cs.ucla.edu>

|
| +
|
| + Fix infringement on user name space reported by Bruno Haible.
|
| + * data/yacc.c (YYSIZE_T): Define first, so that later decls can use it.
|
| + Prefer GCC's __SIZE_TYPE__ if available, so that we don't infringe on
|
| + the user's name space.
|
| + (alloca): Include <stdlib.h> to get it, if it's not built in.
|
| + (YYMALLOC, YYFREE): Define only if needed.
|
| + (malloc, free): Declare, but only if needed, as this infringes on
|
| + the user name space.

| +2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
|
| +
|

|
| +
|
| + * NEWS: Version 2.0a.
|
| +

| + the previous change.
|
| +
|
| + Various maintainer cleanups.
|
| + * .cvsignore: Add a.exe, a.out, b.out,, conf[0-9]*, confdefs*,
|
| + conftest*, for benefit of CVS commands run at the same time as

| + its subfiles.
|
| + * Makefile.cfg (move_if_change): Remove.
|
| + * Makefile.maint: Remove the update stuff; we now use "bootstrap".

|
| +
|

|
| + fopen-safer.c, stdio-safer.h, unistd-safer.h.
|

|
| + (create_subpipe): Make sure all the newly-created
|
| + file descriptors are > 2, so that diagnostics don't
|
| + get sent down them (which might cause Bison to hang, in theory).
|
| + * m4/.cvsignore: Add stdio-safer.m4, unistd-safer.m4.
|

| + <http://lists.gnu.org/archive/html/bug-bison/2005-05/msg00042.html>.
|
| + * data/yacc.c (yyabortlab): Don't call destructor, and
|
| + don't set yychar to EMPTY.
|
| + (yyoverflowlab): Don't call destructor.
|
| + (yyreturn): Call destructor, if yychar is neither YYEOF nor YYEMPTY.
|
| + * tests/calc.at (AT_CHECK_CALC): Expect one fewer output lines,
|

|
| + end of input ()".

|
| +2005-05-20 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
|
| +

|
| +
|
| + Fix some problems reported by twlevo at xs4all.
|
| + * src/symtab.c (symbol_new): Report an error if the input grammar
|
| + contains too many symbols. This is better than calling abort() later.
|
| + * src/vcg.h (enum layoutalgorithm): Remove. All uses removed.
|
| + (struct node, struct graph):
|
| + Rename member expand to stretch. All uses changed.
|
| + (struct graph): Remove member layoutalgorithm. All uses removed.
|

|
| + Add more Doxygen comments.
|
| + (symprint_, stack_print_, reduce_print_, destruct_, pop)
|
| + (report_syntax_error_, translate_): Rename as...
|
| + (yysymprint_, yystack_print_, yyreduce_print_, yydestruct_)

|
| +
|
| +2004-12-15 Akim Demaille <akim@epita.fr>
|
| +
|
| + * data/lalr1.cc (lex_): Rename as...

| + (yylex_): this.
|
| + Move the trace here.
|
| + Take the %name-prefix into account.
|
| + Reported by Alexandre Duret-Lutz.
|
| +
|
| +2004-12-15 Akim Demaille <akim@epita.fr>
|
| +
|
| + Simplify the C++ parser constructor.
|
| +
|
| + * data/lalr1.cc (debug_): Rename as...
|
| + (yydebug_): so that the parser's internals are always in the yy*
|
| + pseudo namespace.
|
| + Adjust uses.
|
| + (b4_parse_param_decl): Remove the leading comma as it is now only
|
| + called as unique argument list.
|
| + (Parser::Parser): Remove the constructor accepting a location and
|
| + an initial debugging level.
|

|
| + * data/lalr1.cc (b4_root, b4_param, b4_constructor): Remove
|
| + definitions and uses.
|
| +
|
| +2004-12-14 Paul Eggert <eggert@cs.ucla.edu>
|
| +
|
| + * data/glr.c (struct yyGLRStack): yyerror_range now has 3 items,
|
| + not 2, since it's not portable to subtract 1 from the start of an
|
| + array. The new item 0 is never set or used. All uses changed.
|
| +
|
| + (yyrecoverSyntaxError): Use YYLLOC_DEFAULT instead of assuming

|
| + by Frank Heckenbach.
|
| +
|
| +2004-12-12 Paul Eggert <eggert@cs.ucla.edu>
|
| +
|
| + * data/glr.c (YYRHSLOC): Don't have two definitions, one for
|
| + the normal case and one for the error case. Just use the
|
| + first one uniformly. Problem reported by Frank Heckenbach.
|
| + (YYLLOC_DEFAULT): Use the conventions of yacc.c, so we can
|
| + use exactly the same macro in both places.
|
| + (yyerror_range): Now of type yyGLRStackItem, not YYLTYPE,
|
| + so that the normal-case YYRHSLOC works for the error case too.
|
| + All uses changed.
|
| + * data/yacc.c (YYRHSLOC): New macro, taken from glr.c.
|
| + (YYLLOC_DEFAULT): Use the same macro as glr.c.
|
| + * doc/bison.texinfo (Location Default Action): Don't claim that
|
| + we have an array of locations. Use the same macro for both glr
|
| + and lalr parsers. Mention YYRHSLOC. Mention what happens when
|
| + the index is 0.

|
| +

|
| + merely a doc fix, since the two types are equivalent).
|
| + (relation_transpose): Relation sizes are of type relation_node,
|
| + not int.
|
| + * src/relation.c: Likewise.
|
| + (top, infinity): Now of type relation_node, not int.

| + (yyparse): Remove unused local introduced in 2004-10-25 patch.
|
| +
|
| + * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): New arg
|
| + specifying whether the test should be skipped. Use it tp
|
| + specify that the [%defines %skeleton "lalr1.cc"] tests currently
|
| + fail on some hosts, and should be skipped.
|
| +
|
| +2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
|
| +
|
| + * src/system.h (CALLOC, MALLOC, REALLOC): Remove. All callers
|
| + changed to use xcalloc, xnmalloc, xnrealloc, respectively,
|
| + unless otherwise specified below.
|
| +
|
| + * src/LR0.c (allocate_itemsets): Use xnmalloc, not xcalloc,

|
| + about whether kernel_size and kernel_base are initialized.
|
| +
|
| + * src/LR0.c (shift_symbol, redset, shiftset, kernel_base,
|
| + kernel_size, kernel_items): Remove unnecessary initialization.

|
| +
|

|

|
| + * src/lalr.h (GOTO_NUMBER_MAXIMUM): New macro.
|
| + * src/lalr.c (set_goto_map): Don't allow ngotos to equal
|
| + GOTO_NUMBER_MAXIMUM, since we occasionally compute

|
| + * src/lalr.c (set_goto_map, map_goto, initialize_F, add_loopback_edge,

|
| +
|
| + * data/lalr1.cc (YYSTYPE): Define it as is done for C, instead
|

|
| + Standards, the others tests, and the doc.
|
| + (_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT_WITH_LOC):

|
| +2004-10-22 Akim Demaille <akim@epita.fr>
|

|
| + by seeing whether it wraps around to zero.
|
| + * src/lalr.h (goto_number): Now size_t, not short int.
|
| + (GOTO_NUMBER_MAXIMUM): Remove.
|
| + * src/relation.c (relation_print, traverse, relation_transpose):

|
| +
|
| +2004-10-22 Paul Eggert <eggert@cs.ucla.edu>
|
| +
|
| + * doc/bison.texinfo (Language and Grammar): In example, "int" is a

|
| +
|
| +2004-10-05 Akim Demaille <akim@epita.fr>
|
| +
|
| + In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
|
| + whether the reducion was empty or not. This leaves room to
|
| + improve the use of YYLLOC_DEFAULT in such a case.
|
| + lalr1.cc is still experimental, so changing this is acceptable.
|
| + And finally, there are probably not many users who changed the
|
| + handling of locations in GLR, so changing is admissible too.
|
| +
|
| + * data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an
|
| + empty reduction, set @$ to an empty location ending the previously

|
| + Adjust uses to make sure the code is triggered on empty

| + reductions.
|
| + * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust the

|
| +2004-09-29 Akim Demaille <akim@epita.fr>

|
| +
|
| +2004-09-29 Akim Demaille <akim@epita.fr>
|
| +
|
| + * data/lalr1.cc: Reinstall the former ctor, for sake of

|
| +
|
| +2004-09-27 Paul Eggert <eggert@cs.ucla.edu>
|

| +
|
| + * src/scan-skel.l: Instead of abort, report error messages to ease

|
| +
|
| +2004-09-16 Akim Demaille <akim@epita.fr>
|
| +
|
| + * data/lalr1.cc (Stack::Iterator, Stack::ConstIterator): Rename as...
|
| + (iterator, const_iterator): these, to be more in the C++ spirit.
|
| + Also, return reverse iterators so that when displaying the stack
|
| + we display its bottom first.
|
| + (Parser::stack_print_, Parser::reduce_print_): Match the messages
|
| + from yacc.c.
|
| + We should probably use vector here though.
|
| +
|
| +2004-09-16 Akim Demaille <akim@epita.fr>
|
| +
|
| + Have more complete shift traces.
|
| +
|
| + * data/yacc.c, data/lalr1.c, data/glr.c: Use YY_SYMBOL_PRINT
|
| + to report Shifts instead of ad hoc YYDPRINTF invocations,
|
| + including for the error token.
|
| + * data/lalr1.cc (symprint_): Output the location.
|
| + * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): In C++, don't
|
| + output the location within the %printer.
|
| + Activate GLR tests, at least to make sure they compile properly.
|
| + They still don't pass though.
|
| + * tests/calc.at: Adjust expect verbose output, since now "Entering
|
| + state..." is on a different line than the "Shifting" message.
|
| +
|
| +2004-09-08 Akim Demaille <akim@epita.fr>
|
| +
|
| + * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
|
| + Bison directive from the Bison file to the invocation of this
|
| + macro, so that these directives are passed to
|
| + AT_BISON_OPTION_PUSHDEFS to get correct help macros.
|
| + Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
|
| + Move the AT_SETUP/AT_CLEANUP outside, to report as test title
|
| + the extra Bison directives instead of the whole series.
|
| + Change the grammar so that there are recoverable errors, and
|
| + unrecoverable errors. Now we can have the parser give up before
|
| + consuming the whole input. As a result we now can observe that
|
| + the lookahead is freed when needed.
|
| + Change the parser source to parse argv[1] instead of a hard coded
|
| + string.
|
| + Simplify yylex, and give a value and location to EOF.
|
| + Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
|
| + passed directives already coded in the file.
|
| + Add some tests to check the location of "error".
|
| + For some tests, the C++ parser is correct, and not yacc.c.
|
| + For other tests, they provide different, but unsatisfying, values,
|
| + so keep the C++ value so that at least one parser is "correct"
|
| + according to the test suite.
|
| + (Actions after errors): Remove, this is subsumed by the
|
| + AT_CHECK_PRINTER_AND_DESTRUCTOR series.

|
| + * data/yacc.cc, data/glr.cc (yydestruct): Accept an additional

| + argument, an informative message.
|
| + Call YY_SYMBOL_PRINT.
|
| + Adjust all callers: integrate the associated YY_SYMBOL_PRINT.
|
| + * data/lalr1.cc (destruct_): Likewise.
|
| + In addition, no longer depend on b4_yysymprint_generate and
|
| + b4_yydestruct_generate to generate these functions, do it "by

| +2004-09-03 Akim Demaille <akim@epita.fr>

|
| + traces: there is an added line for the discarded lookahead.
|
| + * doc/bison.texinfo (Destructor Decl): Some rewording.
|
| + Define "discarded" symbols.
|
| +
|
| +2004-09-02 Akim Demaille <akim@epita.fr>

| + (YYDSYMPRINTF): Rename as...
|
| + (YY_SYMBOL_PRINT): this.
|
| + * data/lalr1.cc (YY_SYMBOL_PRINT): New, modeled after the previous
|
| + two.
|
| + Use it instead of direct symprint_ calls.
|
| + (yybackup): Tweak the "Now at end of input" case to match yacc.c's
|

|
| +2004-09-02 Akim Demaille <akim@epita.fr>
|
| +
|
| + * data/lalr1.cc (b4_yysymprint_generate): New.

|
| + * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust

|
| +
|
| + Adjust to latest gnulib.
|
| + * bootstrap (gnulib_modules): Add xalloc-die.
|
| + Set LC_ALL=C so that file names sort consistently.
|
| + Prefer the gnulib copies of gettext.m4, glibc21.m4,
|
| + inttypes_h.m4, lib-ld.m4, lib-prefix.m4, po.m4, stdint_h.m4,

|
| +
|
| +2004-08-10 Florian Krohm <florian@edamail.fishkill.ibm.com>

|
| + (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't assume %union.
|

|
| +
|
| + Spent a few hours checking out which prerequisite versions the
|
| + current sources actually require. I went all the way back to
|
| + Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
|
| + a seemingly endless set of combinations of versions more recent
|
| + than that. The bottom line is that the current sources require
|
| + fairly recent versions of the build tools, and it'll be some work
|
| + to change this.
|
| + * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
|
| + (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
|
| + (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.

|
| +
|
| + * src/parse-gram.y (lloc_default): Rewrite to avoid compiler bug

|

|
| +
|
| +2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
|
| +
|

|
| + * bootstrap: Remove gettext version checking.
|

|
| + Undo change made earlier today: it caused autopoint to not bring

|
| +
|
| + * bootstrap: Check that gettext version matches what's in
|
| + configure.ac. Warn users to ignore robots.txt ERROR 404.
|
| + * bootstrap: Undo today's earlier change (logged below).
|
| + * configure.ac (AM_GNU_GETTEXT_VERSION): Likewise.
|

|
| + The gettext version checking is causing more trouble than it's
|

|
| +
|

| + yyerrlab), when hitting EOF, pop the whole stack here instead of
|
| + merely falling thru the default error handling mechanism.
|
| + (yyerrorlab): New label, with the old contents of YYERROR,
|
| + plus the following change: pop the stack of rhs corresponding

|

|
| +
|
| + * doc/bison.texinfo (How Can I Reset the Parser): Renamed from
|
| + `How Can I Reset @code{yyparse}', since texinfo does not allow
|
| + arbitrary @ in node names.
|
| +
|
| + * m4/Makefile.am (EXTRA_DIST): Add the following files, which
|
| + shouldn't be needed according to the gettext 0.12.1 documentation
|

|
| + the tests right now.
|
| + * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Ensure yylex and
|
| + yyerror are declared before use; C99 requires this.
|
| +
|
| +2003-06-09 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
|
| +
|
| + * data/glr.c (YYERROR): Update definition to reset yyerrState to 0

|
| + (yyrecoverSyntaxError): Correct the logic for setting and testing
|
| + yyerrState.
|
| + Correct comment on handling EOF.
|
| + Allow states with only a default reduction, rather than failing

| + (I can't quite reconstruct why these were not allowed before).
|
| +
|
| + Fixes to avoid problem that $-N rules in GLR parsers can cause

|
| +
|

|
| +
|

|
| + Remove forward declarations of yylex and yyerror---caused errors
|
| + because default YYLTYPE not yet defined.
|
| + Change semantic actions to compute strings, rather than printing
|
| + them directly (to test proper passing of semantics values). Change
|
| + output to prefix notation and update test data and expected results.
|
| + (yylex): Track locations.
|
| + (stmtMerge): Return value rather than printing, and include arguments
|
| + in value.

| +2003-06-03 Paul Eggert <eggert@twinsun.com>

|
| + * tests/glr-regression.at (Improper handling of embedded actions
|
| + and $-N in GLR parsers): Remove unused local variable from yylex.
|
| + * tests/regression.at (_AT_DATA_DANCER_Y): Declare yylex to take
|
| + (void) as arg when not pure, since we now assume C89 when building
|
| + Bison. Pacify GCC by using parameter.
|
| +
|
| +2003-06-02 Paul Eggert <eggert@twinsun.com>
|
| +
|
| + * data/lalr1.cc (yy::Position::lines, yy::Position::columns,
|
| + yy::Location::lines, yy::Location::columns): Rename arguments
|
| + to avoid shadowing; this removes a warning generated by GCC 3.3.
|
| +
|
| +2003-06-01 Paul Eggert <eggert@twinsun.com>
|
| +
|
| + Don't pass C-only warning optins (e.g., -Wmissing-declarations)
|
| + to g++, as GCC 3.3 complains if you do it.
|
| + * configure.ac (WARNING_CXXFLAGS): New subst. Set it to
|
| + everything that WARNING_CFLAGS has, except omit warnings
|
| + not suitable for C++.
|
| + (AC_PROG_CXX): Use this instead of AC_CHECK_PROGS([CXX], [g++]).
|
| + * tests/atlocal.in (CXXFLAGS): New var.
|
| + * tests/local.at (AT_COMPILE_CXX): Use it instead of CFLAGS.
|
| +
|
| + Fix a GLR parser bug I reported in February; see
|
| + <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
|
| + The problem was that GLR parsers did not conform to the C standard,
|
| + because actions like { $1 = $2 + $3; } expanded to expressions
|
| + that invoked YYFILL in separate subexpressions, and YYFILL assigned
|
| + to a local variable. The C standard says that expressions
|
| + like (var = f ()) + (var = f ()) have undefined behavior.
|
| + Another problem was that GCC sometimes issues warnings that
|
| + yyfill and its parameters are unused.
|
| +
|
| + * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
|
| + as possibly unused.
|
| + (yyfill): New function.
|
| + (YYFILL): Use it.
|
| + (yyuserAction): Change type of yynormal to bool, so that it matches
|
| + the new yyfill signature. Mark it as possibly unused.
|
| +
|
| +
|
| + Follow up on a bug I reported in February, where a Bison-generated
|
| + parser can loop. Provide a test case and a fix for yacc.c. I
|
| + don't have a fix for lalr1.cc or for glr.c, unfortunately.
|
| + The original bug report is in:
|
| + <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00044.html>
|
| +
|
| + * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
|
| + macro's size was becoming unwieldy.
|
| + (yyerrlab): Do not discard an empty lookahead symbol, as this
|
| + might destroy garbage.
|
| + (yyerrorlab): New label, with the old contents of YYERROR,
|
| + plus the following change: pop the stack of rhs corresponding
|
| + to the production that invoked YYERROR. That is how Yacc
|
| + behaves, and POSIX requires this behavior.
|
| + (yyerrlab1): Use YYPOPSTACK instead of its definiens.
|
| + * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
|
| + Define 'alarm' to do nothing if unistd.h is not available.
|
| + Add a new rule "exp: '-' error;" to test the above change to
|
| + data/yacc.c. Use 'alarm' to abort any test taking longer than
|
| + 10 seconds, as it's probably looping.
|
| + (AT_CHECK_CALC): Test recovery from error in new grammar rule.
|
| + Also, the new yacc.c generates two fewer diagnostics for an
|
| + existing test.
|
| +
|
| +2003-05-24 Paul Eggert <eggert@twinsun.com>
|
| +
|
| + * data/glr.c (YYSTACKEXPANDABLE): Do not evaluate
|
| + YYSTYPE_IS_TRIVIAL or YYSTYPE_IS_TRIVIAL unless they are defined.
|
| + This fixes a problem reported by John Bowman when the Compaq/HP
|
| + Alpha cxx compiler happy (e.g. using cxx -D__USE_STD_IOSTREAM
|
| + -ansi -Wall -gall).
|
| + * data/yacc.c (union yyalloc): Likewise.

|
| + * lib/bitset.h (BITSET_FOR_EACH, BITSET_FOR_EACH_REVERSE):

|
| + This should fix a bug reported today by Olatunji Oluwabukunmi in
|

|
| +
|
| + * src/gram.h, src/gram.c (pure_parser, glr_parser): Move to...

| + * src/getargs.c, src/getargs.h: here, as bool, not int.
|
| + (nondeterministic_parser): New.
|
| + * src/parse-gram.y, src/scan-gram.l: Support
|
| + %nondeterministic-parser.
|
| + * src/output.c (prepare): Use nondeterministic_parser instead
|
| + of glr_parser where appropriate.
|
| + * src/tables.c (conflict_row, action_row, save_row)
|
| + (token_actions, token_actions, pack_vector): Ditto.

| +
|

|
| +
|
| +2003-04-29 Akim Demaille <akim@epita.fr>
|
| +
|
| + * tests/calc.at: Also test yacc.c and glr.c (but not lalr1.cc yet)
|
| + with %pure-parser and %locations to exercise the patch from Yakov
|
| + Markovitch below.
|
| +
|
| +2003-04-28 Tim Van Holder <tim.van.holder@pandora.be>
|
| +
|
| + * data/yacc.c: (b4_lex_param): Corrected for the case where
|
| + %lex-param is provided and %pure-parser isn't.
|
| +
|
| +2003-04-27 Paul Eggert <eggert@twinsun.com>
|
| +
|
| + Avoid gcc -Wundef warnings reported by Gerald Pfeifer in
|

|
| +
|
| +2003-04-26 Paul Eggert <eggert@twinsun.com>
|
| +
|
| + * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_):
|
| + Declare to be of type suitable for the ninf value itself, not of
|
| + type suitable for the corresponding table, since the latter might
|
| + be unsigned but the ninf value might be negative. This fixes a
|
| + bug reported by Alexandre Duret-Lutz in
|
| + <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00017.html>.
|
| +
|
| + * configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR
|
| + invokes it. We shouldn't invoke it twice because it will attempt
|
| + to put error.o in the archive twice. This fixes a glitch reported
|
| + by Martin Mokrejs in
|
| + <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
|
| +

|
| +
|
| + * data/glr.c (yyexpandGLRStack) [!YYSTACKEXPANDABLE]:
|
| + Fix obvious typo that results in uncompilable GLR parsers
|
| + when both %pure-parser and %locations are used. (trivial change)
|
| +
|
| +2003-04-17 Paul Eggert <eggert@twinsun.com>
|
| +
|
| + * src/scan-gram.l: Add %option nounput, since we no longer use unput.
|
| + (unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
|
| + Do not insert the expected token via unput, as this runs afoul
|
| + of a POSIX-compatibility bug in flex 2.5.31.
|
| + All uses changed to BEGIN the parent state,
|
| + since we no longer insert the expected token via unput.
|
| + * tests/regression.at (Invalid inputs): Remove cascaded diagnostic
|
| + that is no longer emitted after the above change.
|
| +
|
| + * src/conflicts.c (set_conflicts): Resolve all conflicts, not just
|
| + the first one. This change is from Paul Hilfinger, and it fixes
|
| + regression reported by Werner Lemberg in
|
| + <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
|
| +
|
| + (resolve_sr_conflict): Don't invoke state_errs_set
|
| + unless one or more tokens have been explicitly made errors.
|
| + Otherwise, the above change causes Bison to abort.
|
| +
|
| + * tests/existing.at (GNU pic Grammar): New test case, taken from
|
| + Lemberg's email.
|
| +
|
| +2003-03-31 Akim Demaille <akim@epita.fr>

|
| +
|
| +2003-03-12 Paul Eggert <eggert@twinsun.com>
|
| +
|
| + * scan-gram.l (YY_USER_INIT): Initialize code_start, too.
|
| + (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
|
| + cursor, instead of leaving it undefined. This fixes a bug
|
| + reported by Tim Van Holder in
|
| + <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>.
|
| + * tests/input.at (Torturing the Scanner): Test the scanner on
|
| + an empty input file, which was Tim Van Holder's test case.
|
| +
|
| + * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether
|
| + <sys/resource.h> can be included, include sys/time.h and
|
| + sys/times.h first, if available. This works around the SunOS
|
| + 4.1.4 porting bug reported by Bruce Becker in
|
| + <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>.
|
| +
|
| + * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't
|
| + AC_CHECK_HEADERS([sys/wait.h]), as this interferes with
|
| + AC_HEADER_SYS_WAIT.
|
| +
|
| + Merge changes from gnulib. This was prompted because the CVS
|
| + snapshot didn't build on Solaris 7 due to strnlen problems.
|
| +
|
| + These changes need to be merged back into gnulib:
|
| + * lib/hash.c: Include <stdbool.h> unconditionally.

|
| + (AC_CHECK_HEADERS_ONCE, AC_CHECK_FUNCS_ONCE, AC_CHECK_DECLS_ONCE):

|
| + Use the number of tokens as an upper bound in yytname, as it

| +2003-03-01 Paul Eggert <eggert@twinsun.com>
|
| +
|
| + * src/scan-gram.l (code_start): Initialize it to scanner_cursor,
|
| + not loc->end, since loc->end might contain garbage and this leads
|
| + to undefined behavior on some platforms.
|
| + (id_loc, token_start): Use (IF_LINTed) initial values that do not
|
| + depend on *loc, so that the reader doesn't give the the false
|
| + impression that *loc is initialized.
|
| + (<INITIAL>"%%"): Do not bother setting code_start, since its value

|

|
| +
|

|
| +
|
| +2003-02-20 Akim Demaille <akim@epita.fr>
|
| +
|

|
| +
|
| +2003-02-02 Akim Demaille <akim@epita.fr>
|
| +
|

|
| +
|
| +2003-02-01 Paul Eggert <eggert@twinsun.com>
|
| +
|
| + Version 1.875a.
|
| +
|
| + * po/LINGUAS: Add ms.
|
| +
|
| +2003-01-30 Akim Demaille <akim@epita.fr>
|
| +
|
| + * doc/Makefile.am (CLEANFILES): Add bison.fns for distcheck.
|
| +
|
| +2003-01-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
|
| +
|
| + * tests/cxx-type.at: Correct apparent typo in Bison input: $$ instead
|
| + of $1.
|
| +
|
| + Changes in response to error report by S. Eken: GLR mode does not
|
| + handle negative $ indices or $ indices in embedded rules correctly.
|
| + See <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00076.html>.
|
| +
|
| + * data/glr.c (b4_rhs_value): Change to use YYFILL macro.
|
| + (b4_rhs_location): Ditto.
|
| + (yyfill): New function to copy from stack tree into array
|
| + incrementally.
|
| + (yyuserAction): Modify to allow incremental move of semantic values
|
| + to rhs array when in GLR mode.
|
| + Define YYFILL to use in user-defined actions to fill semantic array
|
| + as needed.
|
| + Remove dummy use of yystack, as there is now a guaranteed use.
|
| + (yydoAction): Modify to allow incremental move of semantic values
|
| + to rhs array when in GLR mode.
|
| + (yyresolveAction): Ditto.
|
| + (yyglrShiftDefer): Update comment.
|
| + (yyresolveStates): Use X == NULL for pointers, not !X.
|
| + (yyglrReduce): Ditto.
|
| + (yydoAction): Ditto
|
| +
|
| + * tests/glr-regr1.at: Rename to ...
|
| + * tests/glr-regression.at: Add new regression test for the problems
|
| + described above (adapted from S. Eken).
|
| + Update copyright notice.
|
| + * tests/testsuite.at: Rename glr-regr1.at to glr-regression.at.
|
| + * tests/Makefile.am: Ditto.
|
| +
|
| +2003-01-28 Paul Eggert <eggert@twinsun.com>
|
| +
|
| + * data/lalr1.cc: Do not use @output_header_name@ unless
|
| + b4_defines_flag is set. This fixes two bugs reported by
|
| + Tim Van Holder in
|
| + <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00071.html>
|
| + and <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>.
|
| +
|
| +2003-01-21 Paul Eggert <eggert@twinsun.com>
|
| +
|
| + * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
|
| + we don't need to worry about yyerrlab1 being reported as an
|
| + "unused label" by non-GCC C compilers. The downside is that if
|
| + locations are used then a couple of statements are duplicated each
|
| + time YYERROR is invoked, but the upside is that the warnings
|
| + should vanish.
|
| + (yyerrlab1): Move code to YERROR.
|
| + (yyerrlab2): Remove. Change uses back to yyerrlab1.
|
| + This reverts some of the 2002-12-27 change.
|
| +
|
| +2003-01-17 Paul Eggert <eggert@twinsun.com>
|
| +
|
| + * src/output.c (symbol_printers_output): Fix typo that led
|
| + to core dump. Problem reported by Antonio Rus in
|
| + <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00058.html>.

|
| + Quoc Peyrot <chojin@lrde.epita.fr>,
|
| + Robert Anisko <anisko_r@lrde.epita.fr>
|
| +
|
| + * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
|
| + when the stacks contain one element, as the loop would otherwise
|
| + free the last state, and then use the top state (the one we just
|
| + popped). This means that the initial elements will not be freed
|
| + explicitly, as is the case in yacc.c; it is not a problem, as
|
| + these elements have fake values.
|
| +
|
| +2003-01-11 Paul Eggert <eggert@twinsun.com>
|
| +
|
| + * NEWS: %expect-violations are now just warnings, reverting
|
| + to Bison 1.30 and 1.75 behavior. This fixes the GCC 3.2
|
| + bootstrapping problem reported by Matthias Klose; see
|
| + <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>.
|
| + * src/conflicts.c (conflicts_print): Likewise.
|
| + * tests/conflicts.at (%expect not enough, %expect too much,
|
| + %expect with reduce conflicts): Likewise.
|
| + * doc/bison.texinfo (Expect Decl): Document this. Also mention
|
| + that the warning is enabled if the number of conflicts changes
|
| + (not necessarily increases).
|
| +
|
| + * src/getargs.c (version): Update copyright year.
|
| +
|
| +2003-01-09 Akim Demaille <akim@epita.fr>
|
| +
|
| + * src/Makefile.am, lib/Makefile.am: Use $(VAR) instead of @VAR@.
|
| +
|
| +2003-01-08 Paul Eggert <eggert@twinsun.com>
|
| +
|
| + * Makefile.maint (WGETFLAGS):
|
| + New macro, containing "-C off" to disable proxy caches.
|
| + All uses of $(WGET) changed to $(WGET) $(WGETFLAGS).
|
| + (rel-check): Use $(WGET) instead of wget.
|
| +
|
| +2003-01-06 Paul Eggert <eggert@twinsun.com>
|
| +
|
| + * doc/bison.texinfo (Generalized LR Parsing): Add a reference to
|
| + the GLR paper of Scott, Johnstone and Hussain.
|
| +
|
| +2003-01-04 Paul Eggert <eggert@twinsun.com>
|
| +
|
| + * configure.ac (AC_ARG_ENABLE): Add --disable-yacc.
|
| + (YACC_SCRIPT, YACC_LIBRARY): New vars to AC_SUBST.
|
| + * lib/Makefile.am (lib_LIBRARIES): liby.a -> @YACC_LIBRARY@.
|
| + (EXTRA_LIBRARIES): New var, for liby.a.
|
| + * src/Makefile.am (bin_SCRIPTS): yacc -> @YACC_SCRIPT@.
|
| + (EXTRA_SCRIPTS): New var, for yacc.
|
| +
|
| + * data/yacc.c (yyerrlab1): Omit attribute if __cplusplus is defined,
|
| + since GNU C++ (as of 3.2.1) does not allow attributes on labels.
|
| + Problem reported by Nelson H. F. Beebe.
|
| +
|
| +2003-01-03 Paul Eggert <eggert@twinsun.com>
|
| +
|
| + * lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to
|
| + (void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
|
| + when compiling Bison 1.875's `bitset bset = obstack_alloc
|
| + (bobstack, bytes);'. Problem reported by Nelson H. F. Beebe.
|
| +
|
| + * src/scan-skel.l (QPUTS): Omit redundant `;' from macro definition.
|
| + ([^@\n]): Renamed from [^@\n]+ so that the token buffer does not
|
| + grow to a huge size with typical invocation.
|
| +
|
| + * lib/hash.c (_Bool, bool, false, true, __bool_true_false_are_defined):
|
| + Use the pattern recommended by Autoconf 2.57, except also protect
|
| + against double-definition.
|
| + * src/system.h: Likewise.
|
| + Portability issues reported by Nelson H. F. Beebe.
|
| +
|
| + * data/glr.c (yybool): Renamed from bool, to avoid collisions in C.
|
| + All uses changed. Provide a definition in both C and C++.
|
| + (yytrue, yyfalse): Define even if defined (__cplusplus).
|
| +
|
| + * lib/bitset_stats.c (bitset_stats_list): Remove unused var.
|
| + Reported by Nelson H. F. Beebe.
|
| +
|
| + * src/scan-skel.l ("@oline@"): Output lineno+1, not lineno.
|
| +
|
| +2003-01-02 Paul Eggert <eggert@twinsun.com>
|
| +
|
| + * data/yacc.c (yyerrlab1): Append `;' after attribute, to
|
| + pacify the buggy "smart preprocessor" in MacOS 10.2.3.
|
| + Bug reported by Nelson H. F. Beebe.
|
| +
|
| +2003-01-01 Paul Eggert <eggert@twinsun.com>
|
| +
|
| + * Version 1.875.
|
| +
|
| +2002-12-30 Paul Eggert <eggert@twinsun.com>
|
| +
|
| + * src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","):
|
| + Moved here from...
|
| + (<INITIAL>","): Here. This causes stray "," to be treated
|
| + more uniformly.
|
| +
|
| + * src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the
|
| + last brace in braced code when not in Yacc mode, for compatibility
|
| + with Bison 1.35. This resurrects the 2001-12-15 patch to
|
| + src/reader.c.
|
| +
|
| + * src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias
|
| + yystype. This follows up the 2002-12-24 YYSTYPE bug fix.
|
| +
|
| +2002-12-28 Paul Eggert <eggert@twinsun.com>
|
| +
|
| + * src/symtab.c (symbol_make_alias): Set type of SYMVAL to be
|
| + that of SYM's type. This fixes Debian bug 168069, reported by
|
| + Thomas Olsson.
|
| +
|
| +2002-12-28 Paul Eggert <eggert@twinsun.com>
|
| +
|
| + Version 1.75f.
|
| +
|
| + Switch back to the Yacc style of conflict reports, undoing some
|
| + of the 2002-07-30 change.
|
| + * doc/bison.texinfo (Understanding): Use Yacc style for
|
| + conflict reports. Also, use new way of locating rules.
|
| + * src/conflicts.c (conflict_report):
|
| + Renamed from conflict_report_yacc, removing the old
|
| + 'conflict_report'. Translate the entire conflict report at once,
|
| + so that we don't assume that "," has the same interpretation in
|
| + all languages.
|
| + (conflicts_output): Use Yacc-style conflict report for each state,
|
| + instead of our more-complicated style.
|
| + (conflicts_print): Use Yacc-style conflict report, except print
|
| + the input file name when not emulating Yacc.
|
| + * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
|
| + Conflicted Reduction, %expect not enough, %expect too much,
|
| + %expect with reduce conflicts): Switch to Yacc-style conflict reports.
|
| + * tests/existing.at (GNU Cim Grammar): Likewise.
|
| + * tests/glr-regr1.at (Badly Collapsed GLR States): Likewise.
|
| +
|
| + * src/complain.c (warn_at, warn, complain_at, complain, fatal_at,
|
| + fatal): Don't invoke fflush; it's not needed and it might even be
|
| + harmful for stdout, as stdout might not be open.
|
| + * src/reduce.c (reduce_print): Likewise.
|
| +
|
| +2002-12-27 Paul Eggert <eggert@twinsun.com>
|
| +
|
| + Fix a bug where error locations were not being recorded correctly.
|
| + This problem was originally reported by Paul Hilfinger in
|
| + <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>.
|
| +
|
| + * data/yacc.c (yyparse): New local var yylerrsp, to record the
|
| + top of the location stack's error locations.
|
| + (yyerrlab): Set it. When discarding a token, push its location
|
| + onto yylerrsp so that we don't lose track of the error's end.
|
| + (yyerrlab1): Now is only the target of YYERROR, so that we can
|
| + properly record the location of the action that failed. For GCC
|
| + 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
|
| + GCC warning about yyerrlab1 being unused if YYERROR is unused.
|
| + (yyerrlab2): New label, which yyerrlab now falls through to.
|
| + Compute the error's location by applying YYLLOC_DEFAULT to
|
| + the locations of all the symbols that went into the error.
|
| + * doc/bison.texinfo (Location Default Action): Mention that
|
| + YYLLOC_DEFAULT is also invoked for syntax errors.
|
| + * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
|
| + Error locations include the locations of all the tokens that were
|
| + discarded, not just the last token.
|
| +
|
| +2002-12-26 Paul Eggert <eggert@twinsun.com>
|
| +
|
| + * src/files.c: Include quote.h.
|
| + (compute_output_file_names): Warn if we detect conflicting
|
| + outputs to the same file. This should catch the misunderstanding
|
| + exemplified by Debian Bug 165349, reported by Bruce Stephens..
|
| +
|
| + * src/conflicts.c (conflicts_print): If the user specifies
|
| + "%expect N", report an error if there are any reduce/reduce
|
| + conflicts. This is what the manual says should happen.
|
| + This fixes Debian bug 130890, reported by Anthony DeRobertis.
|
| + * tests/conflicts.at (%expect with reduce conflicts): New test.
|
| +
|
| + Don't use m4_include on relative file names, as it doesn't work as
|
| + desired if there happens to be a file with that name under ".".
|
| +
|
| + * m4sugar/version.m4: Remove; it was included but it wasn't used.
|
| + * data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4.
|
| + * data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4.
|
| + * data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4.
|
| + * src/output.c (output_skeleton): Use full path names when
|
| + specifying a file to include; don't rely on include path, as
|
| + it's unreliable when the working file contains a file with
|
| + that name.
|
| +
|
| +2002-12-25 Paul Eggert <eggert@twinsun.com>
|
| +
|
| + Remove obsolete references to bison.simple and bison.hairy.
|
| + Problem mentioned by Aubin Mahe in
|
| + <http://lists.gnu.org/archive/html/help-bison/2002-12/msg00010.html>.
|
| + * data/glr.c: Comment fix.
|
| + * doc/bison.1: Remove references. Also, mention "yacc".
|
| +
|
| + * src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL
|
| + with -g option.
|
| +
|
| + * src/parse-gram.y (declaration): Use enum "report_states" rather
|
| + than its numeric value 1.
|
| +
|
| + * src/scan-skel.l ("@output ".*\n): Close any old yyout before
|
| + opening a new one. This fixes Debian bug 165349, reported by
|
| + Bruce Stephens.
|
| +
|
| +2002-12-24 Paul Eggert <eggert@twinsun.com>
|
| +
|
| + Version 1.75e.
|
| +
|
| + * Makefile.maint (cvs-update): Don't assume that the shell
|
| + supports $(...), as Solaris sh doesn't.
|
| +
|
| + * src/parse-gram.y (lloc_default): Remove test for empty
|
| + nonterminals at the end, since it didn't change the result.
|
| +
|
| +2002-12-24 Paul Eggert <eggert@twinsun.com>
|
| +
|
| + If the user does not define YYSTYPE as a macro, Bison now declares it
|
| + using typedef instead of defining it as a macro. POSIX requires this.
|
| + For consistency, YYLTYPE is also declared instead of defined.
|
| +
|
| + %union directives can now have a tag before the `{', e.g., the
|
| + directive `%union foo {...}' now generates the C code
|
| + `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
|
| + The default union tag is `YYSTYPE', for compatibility with Solaris 9
|
| + Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
|
| + instead of `yyltype'.
|
| +
|
| + `yystype' and `yyltype' are now obsolescent macros instead of being
|
| + typedefs or tags; they are no longer documented and will be
|
| + withdrawn in a future release.
|
| +
|
| + * data/glr.c (b4_location_type): Remove.
|
| + (YYSTYPE): Renamed from yystype.
|
| + (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
|
| + (struct YYLTYPE): Renamed from struct yyltype.
|
| + (YYLTYPE): Renamed from yyltype.
|
| + (yyltype, yystype): New (and obsolescent) macros,
|
| + for backward compatibility.
|
| + * data/yacc.c: Likewise.
|
| +
|
| + * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
|
| + does not specify a union tag. This is for compatibility with
|
| + Solaris 9 yacc.
|
| +
|
| + * src/parse-gram.y (add_param): 2nd arg is now char * not char
|
| + const *, since it is now modified by stripping surrounding { }.
|
| + (current_braced_code): Remove.
|
| + (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
|
| + PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
|
| + trailing " {...}". Now of type <chars>.
|
| + (grammar_declaration): Adjust to bundled tokens.
|
| + (code_content): Remove; stripping is now done by add_param.
|
| + (print_token_value): Print contents of bundled tokens.
|
| + (token_name): New function.
|
| +
|
| + * src/reader.h (braced_code, current_braced_code): Remove.
|
| + (token_name): New decl.
|
| +
|
| + * src/scan-gram.l (handle_dollar, handle_at): Now takes int
|
| + token_type, not braced_code code_kind. All uses changed.
|
| + (SC_PRE_CODE): New state, for scanning after a keyword that
|
| + has (or usually has) an immediately-following braced code.
|
| + (token_type): New local var, to keep track of which token type
|
| + to return when scanning braced code.
|
| + (<INITIAL>"%destructor", <INITIAL>"%lex-param",
|
| + <INITIAL>"%parse-param", <INITIAL>"%printer",
|
| + <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
|
| + instead of returning a token type immediately.
|
| + (<INITIAL>"{"): Set token type.
|
| + (<SC_BRACED_CODE>"}"): Use it.
|
| + (handle_action_dollar, handle_action_at): Now returns bool
|
| + indicating success. Fail if ! current_rule; this prevents a core dump.
|
| + (handle_symbol_code_dollar, handle_symbol_code_at):
|
| + Remove; merge body into caller.
|
| + (handle_dollar, handle_at): Complain in invalid contexts.
|
| +
|
| + * NEWS, doc/bison.texinfo: Document the above.
|
| + * NEWS: Fix years and program names in copyright notice.
|
| +
|
| +2002-12-17 Paul Eggert <eggert@twinsun.com>
|
| +
|
| + * NEWS, doc/bison.texinfo (Parser Function, Pure Calling, Error
|
| + Reporting, Table of Symbols): Omit mentions of %lex-param and
|
| + %parse-param from the documentation for now.
|
| +
|
| +2002-12-15 Paul Eggert <eggert@twinsun.com>
|
| +
|
| + Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke
|
| + GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
|
| + lookahead symbol, and which sets yychar in parser actions) and it
|
| + disagreed with the Bison documentation. Bug
|
| + reported by Andrew Walrond.
|
| +
|
| + * data/yacc.c (YYTRANSLATE): Don't check for negative argument,
|
| + as the caller now does that.
|
| + (yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
|
| + (YYEMPTY): Parenthesize right hand side, since others use it.
|
| + (yyparse): Don't assume that our generated code is the only code
|
| + that sets yychar.
|
| +
|
| +2002-12-13 Paul Eggert <eggert@twinsun.com>
|
| +
|
| + Version 1.75d.
|
| +
|
| + POSIX requires a "yacc" command.
|
| + * src/Makefile.am (bin_SCRIPTS): New macro, for yacc.
|
| + (MOSTLYCLEANFILES): Add yacc.
|
| + (yacc): New rule.
|
| + * doc/bison.texinfo (Invocation, Bison Options): Mention yacc
|
| + as an alias for bison y.
|
| +
|
| + * po/LINGUAS: Add da.
|
| +

|
| +
|
| + Remove unportable casts and storage allocation tricks.
|
| + While we're at it, remove almost all casts, since they

|
| +
|
| + * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
|
| +
|
| + * src/derives.c (derives_compute): Do not subtract NTOKENS from
|

|
| +
|
| + * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
|
| + var instead of casting to long, to avoid casts.

| + * src/state.c (state_hash_lookup): Likewise.
|
| +
|
| + * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char

|
| + STATE_ALLOC): Remove.
|
| + (transitions_new, errs_new, reductions_new, state_new): Use malloc

|
| + too much storage.

| + (state_new): Initialize all members.
|
| +
|

|

|
| +
|
| + Change identifier spellings to avoid collisions with names
|
| + that are reserved by POSIX.
|
| +
|
| + Don't use names ending in _t, since POSIX reserves them.
|
| + For consistency, remove _e and _s endings -- they're weren't

|
| + (<INITIAL>"'", "\""): Save token_start.
|
| + (<INITIAL>"%{", "{", "%%"): Save code_start.
|
| + (<SC_AFTER_IDENTIFIER>): New state, looking for a colon.

|
| +
|

|
| + Type clashes now generate warnings, not errors, since it

|
| + for consistency.
|
| +
|
| +2002-11-29 Paul Eggert <eggert@twinsun.com>
|
| +
|
| + * doc/bison.texinfo: Emphasize that yylex and yyerror must
|
| + be declared before being used. E.g., one should typically
|
| + declare them in the prologue. Use GNU coding style in examples.
|
| + Put "const" consistently after the type it modifies. Mention
|
| + that C99 supports "inline". Mention that yyerror traditionally
|
| + returns "int".
|
| +
|
| + %parse-param and %lex-param now take just one argument, the
|
| + declaration; the argument name is deduced from the declaration.
|
| +
|
| + * doc/bison.texinfo (Parser Function, Pure Calling, Error
|
| + Reporting, Table of Symbols): Document this.
|

|
| + (COMMA): Remove.
|
| + (declaration): Implement new rule for %parse-param and %lex-param.
|
| + * src/scan-gram.l: "," now elicits a warning, rather than being
|
| + a token; this is more compatible with byacc.
|
| + * tests/calc.at (Simple LALR Calculator): Adopt new convention.
|
| +
|
| +2002-11-27 Paul Eggert <eggert@twinsun.com>

| +
|
| + Rename identifiers to avoid real and potential collisions.
|
| +
|
| + * data/c.m4 (b4_yysymprint_generate): yyout -> yyoutput,

|
| + * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
|
| + * doc/bison.texinfo (Prologue, Tracing): yyprint -> print_token_value.
|
| + * src/parse-gram.y (print_token_value): Renamed from yyprint.
|
| + All uses changed.
|
| + (YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove. All uses changed.
|
| + The name "yycontrol" violates the name space rules, and this stuff
|
| + wasn't being used anyway.
|
| + (input): Remove action; this stuff wasn't being used.
|
| + (gram_error): Rename local variable yylloc -> loc.
|
| + * src/reader.h (struct gram_control_s, gram_control_t): Remove.

|
| +
|
| + Version 1.75c.
|
| +
|
| + * tests/actions.at (Actions after errors): Use an output format
|
| + more similar to that of the Printers and Destructors test.
|
| + Test the position of the ';' token too.
|
| + (Printers and Destructors): Likewise.
|
| + (Printers and Destructors: %glr-parser): Remove for now, to avoid
|
| + unnecessarily alarming people when the test fails.
|
| +
|
| + * data/yacc.c (yyerrlab1): Move this label down, so that the
|
| + parser does not discard the lookahead token if the user code
|

|
| + Avoid use of <assert.h>, as the GNU Coding Standards hint that one

|
| +
|
| + * data/glr.c (yygetLRActions): Replace `yyindex' with
|
| + `yytable[yyindex]' to fix typo introduced in my 2002-11-09 patch.
|
| + This fixes the regression with Sun ONE Studio 7 cc that I reported in

|
| +
|

|
| + From Tim Van Holder.
|
| +
|
| +2002-11-17 Paul Eggert <eggert@twinsun.com>
|
| +
|
| + Pacify Sun ONE Studio 7 lint. Also, rename "ParseError"

|
| +
|
| + * data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do
|
| + not define to {}, since this breaks the common use of `YYDPRINTF
|
| + ((...));' if a single statement is desired (e.g. before `else').
|
| + Work around GCC warnings by surrounding corresponding calls with

|

|
| + All uses changed.

|
| +2002-11-16 Akim Demaille <akim@epita.fr>
|

|
| +
|
| +2002-11-16 Akim Demaille <akim@epita.fr>
|

|

|
| +2002-11-15 Tim Van Holder <tim.van.holder@pandora.be>
|

|
| +
|
| + * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
|
| + "$CC -E foo.h" is allowed, as this doesn't work with the Portland
|
| + Group compiler. Instead, use "$CC -E bar.c". Include the .h
|
| + file twice in the grammar, as an extra check.
|
| +
|
| + * tests/input.at (Torturing the Scanner): Surround the
|
| + backslash-newline tests with "#if 0", to make it less likely that
|
| + we'll run into compiler bugs. Bring back solitary \ inside
|
| + comment, but add a closing comment to work around HP C bug. Don't

|
| + * tests/headers.at (export YYLTYPE): Likewise.
|
| +
|
| + * tests/input.at (Torturing the Scanner): Remove lines containing

|
| +
|
| + * tests/glr-regr1.at (Badly Collapsed GLR States): Avoid //

| + (bitset_set, bitset_reset, bitset_test): Rename local vars
|

|
| +
|
| + * data/glr.c (inline): Remove #define. It's the user's

|
| + This fixes one of the bugs reported by Nelson H. F. Beebe in
|
| + <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00058.html>.
|
| +
|

|
| +
|
| + Revamp to fix many (but not all) of the C- and M4-related quoting
|
| + problems. Among other things, this fixes the Bison bug reported
|
| + by Jan Hubicka when processing the Bash grammar; see:
|
| + <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00039.html>
|
| +
|
| + Use new @ escapes consistently. Represent brackets with @{ and @}
|
| + rather than @<:@ and @:>@, since this works a bit better with dumb
|
| + editors like vi. Represent @ with @@, since @ is now consistently
|
| + an escape. Use @oline@ and @ofile@ rather than __oline__ and
|
| + __ofile__, to avoid unexpected expansions. Similarly, use @output
|
| + rather than #output.
|
| +
|
| + * data/c.m4 (b4_copyright): Omit file name from comment, since
|
| + the file name could contain "*/".
|
| + (b4_synclines_flag): Don't quote the 2nd argument; it should already
|
| + be quoted. All uses changed.
|
| +
|
| + * data/glr.c: Use new @ escapes consistently.
|
| + (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
|
| + b4_output_header_suffix, b4_output_header_name, b4_header_guard):
|
| + Remove, since they couldn't handle arbitrary characters in file
|
| + names.
|
| + * data/lalr1.cc: Likewise.
|
| + * data/yacc.c: Likewise.
|
| +
|
| + * src/files.c (output_infix): Remove; all uses removed.
|
| + * src/files.h: Likewise.
|
| +
|
| + * data/glr.c: Remove use of "#ifdef b4_header_guard", since it
|
| + mishandled funny characters in file names, and anyway it isn't
|
| + needed any more.
|
| + * data/yacc.c: Likewise.
|
| + * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
|
| +
|
| + * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
|
| + * data/yacc.c: Likewise.
|
| +
|
| + * src/muscle_tab.c: Include quotearg.h, since we need to quote C
|
| + strings now.
|
| + (muscle_init): Quote filename as a C string.
|
| + * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused.
|
| + (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.
|
| + * src/output.c (escaped_file_name_output): New function.
|
| + (prepare_symbols): Quote tokens for M4.
|
| + (prepare): Don't insert output_infix, output_prefix,
|
| + output_parser_name, output_header_name; this is now down by scan-skel.
|
| + Insert skeleton as a C string.
|
| +
|
| + * src/output.c (user_actions_output, symbol_destructors_output,
|
| + symbol_printers_output): Quote filenames for C and M4.
|
| + * src/reader.c (prologue_augment, epilogue_set): Likewise.
|
| +
|
| + * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
|
| + escapes other than \\ and \'; this simplifies the code.
|
| + (<SC_STRING>): Likewise, for \\ and \".
|
| + (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
|
| + SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
|
| + Use new escapes @{ and @} for [ and ].
|
| +
|
| + * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
|
| + them with auto vars.
|
| + Switch to new escape scheme, where @ is the escape character uniformly.
|
| + Abort if a stray escape character is found. Avoid unbounded input
|
| + buffer when parsing non-escaped text.
|
| +
|
| + * tests/input.at (Torturing the Scanner): Add tests that @oline@,
|
| + __oline__, #output, $@, and @{ do not have unintended meanings.
|
| +
|
| +2002-11-09 Paul Eggert <eggert@twinsun.com>
|
| +
|
| + Fix the test failure due to GCC warnings described in
|
| + <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00000.html>.
|
| + * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which
|
| + evaluate to 0 if it's impossible for NINF to be in the respective
|
| + table.
|
| + (yygetLRActions, yyrecoverParseError): Use them.
|
| +
|
| + * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
|
| + counted in the token inserted at end of file. Now takes
|
| + location_t *, not location_t, so that the location can be
|
| + adjusted. All uses changed.
|
| +
|
| + * tests/regression.at (Invalid inputs): Adjust wording in
|
| + diagnostic to match the new behavior.
|
| +
|
| + * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
|
| + AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
|
| + AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
|
| + abort ();'. This reduces the runtime of the "Many lookaheads"
|
| + test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running
|
| + GCC 3.2.
|
| +
|
| +2002-11-07 Paul Eggert <eggert@twinsun.com>
|
| +
|
| + * src/parse-gram.y (CHARACTER): Remove unused token.
|
| + All uses removed.
|
| +
|
| + * src/scan-gram.l: Remove stack option. We no longer use the
|
| + stack, since the stack was never deeper than 1; instead, use the
|
| + new auto var c_context to record the stacked value.
|
| +
|
| + Remove nounput option. At an unexpected end of file, we now unput
|
| + the minimal input necessary to end cleanly; this simplifies the
|
| + code.
|
| +
|
| + Avoid unbounded token sizes where this is easy.
|
| +
|
| + (unexpected_end_of_file): New function.
|
| + Use it to systematize the error message on unexpected EOF.
|
| + (last-string): Now auto, not static.
|
| + (YY_OBS_FREE): Remove unnecessary do while (0) wrapper.
|
| + (scanner_last_string_free): Remove; not used.
|
| + (percent_percent_count): Move decl to just before use.
|
| + (SC_ESCAPED_CHARACTER): Return ID at unexpected end of file,
|
| + not the (never otherwised-used) CHARACTER.
|
| +
|
| +2002-11-07 Akim Demaille <akim@epita.fr>

|
| +
|
| + Version 1.75a.
|
| +
|
| + * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration.
|
| + * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since
|
| + we use malloc. Don't assume 'A' through 'Z' are contiguous.
|
| + Don't assume strdup exists; POSIX says its an XSI extension.
|
| + Check for buffer overflow on input.
|
| +
|
| +2002-10-24 Akim Demaille <akim@epita.fr>
|
| +
|
| + * src/output.c (output_skeleton): Don't disable M4sugar comments
|
| + too soon: it results in comments being expanded.
|
| + * data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the
|
| + first output.
|
| +
|
| +2002-10-24 Akim Demaille <akim@epita.fr>
|
| +
|
| + * data/yacc.c (m4_int_type): New.
|
| + * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed
|
| + char' as only yacc.c wants K&R portability.
|
| + * data/glr.c (yysigned_char): Remove.
|
| + * data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name.
|
| + Reported by Quoc Peyrot.

|
| +2002-10-23 Paul Eggert <eggert@twinsun.com>
|
| +
|
| + * src/main.c (main): With --trace=time, report times even if a
|
| + non-fatal error occurs. Formerly, the times were reported in some
|
| + such cases but not in others.
|
| + * src/reader.c (reader): Just return if a complaint has been issued,
|
| + instead of exiting, so that 'main' can report times.
|
| +
|
| +2002-10-22 Akim Demaille <akim@epita.fr>
|
| +
|
| + * src/system.h: Include sys/types.
|
| + Reported by Bert Deknuydt.
|
| +
|
| +2002-10-23 Paul Eggert <eggert@twinsun.com>
|
| +
|
| + * configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX.
|
| + Suggested by Art Haas.
|
| +
|
| +2002-10-22 Paul Eggert <eggert@twinsun.com>
|
| +
|
| + * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
|
| + decl; not needed any more.
|
| + * src/main.c (main): Use return to exit, undoing yesterday's change.
|
| + The last OS that we could find where this wouldn't work is
|
| + SunOS 3.5, and that's too old to worry about now.
|
| +
|
| + * data/glr.c (struct yyltype): Define members even when not
|
| + doing locations. This is more consistent with yacc.c, and it
|
| + works around the following bug reports:
|
| + http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00106.html
|
| + http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00111.html
|
| +
|
| + * doc/bison.texinfo: Minor spelling and typographical fixes. Use
|
| + @acronym consistently. Standardize on "Yacc" instead of "YACC",
|
| + "Algol" instead of "ALGOL". Give a bit more history about BNF.
|
| +
|
| +2002-10-22 Akim Demaille <akim@epita.fr>
|
| +
|
| + * data/README: New.
|
| +
|
| +2002-10-21 Paul Eggert <eggert@twinsun.com>
|
| +
|
| + Be consistent about 'bool'; the old code used an enum in one
|
| + module and an int in another, and this violates the C standard.
|
| + * m4/stdbool.m4: New file, from coreutils 4.5.3.
|
| + * configure.ac (AC_HEADER_STDBOOL): Add.
|
| + * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.
|
| + * src/muscle_tab.c (hash_compare_muscles): (a ? FALSE : TRUE) -> (! a)
|
| + * src/symtab.c (hash_compare_symbol_t): Likewise.
|
| + * src/system.h (bool, false, true): Use a definition consistent
|
| + with ../lib/hash.c. All uses changed.
|
| +
|
| + * src/complain.c (warning_issued): Renamed from warn_message_count,
|
| + so that we needn't worry about integer overflow (!).
|
| + Now of type bool. All uses changed.
|
| + (complaint_issued): Renamed from complain_message_count; likewise.
|
| +
|
| + * src/main.c (main): Use exit to exit with failure.
|
| +
|
| + * src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS
|
| + rather than 1 and 0.
|
| + * src/main.c (main): Likewise.
|
| + * src/getargs.c (getargs): Likewise.
|
| + * src/reader.c (reader): Likewise.
|

| + * src/getarg.c (getargs): Remove duplicate code for
|
| + "Try `bison --help'".
|
| +
|
| + * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
|
| + What was that "2" for?
|
| +
|
| + * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
|
| + * src/getargs.c (usage): Likewise.
|
| +
|
| + * src/getargs.c (getargs): When there are too few operands, report
|
| + the last one. When there are too many, report the first extra
|
| + one. This is how diffutils does it.
|
| +
|
| +2002-10-20 Paul Eggert <eggert@twinsun.com>
|
| +
|
| + Remove K&R vestiges.
|
| + * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove.
|
| + * src/complain.c (VA_START): Remove. Assume prototypes.
|
| + (vfprintf) [! (HAVE_VPRINTF || defined vfprintf)]: New macro.
|
| + (private_strerror, warn_at, warn, complain_at, complain, fatal_at,
|
| + fatal): Assume prototypes.
|
| + * src/complain.h: Assume prototypes.
|
| + * src/system.h (PARAMS): Remove.
|
| + Include <limits.h> unconditionally, since it's guaranteeed even
|
| + for a freestanding C89 compiler.
|
| + (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.
|
| + * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype.
|
| +
|
| +2002-10-20 Akim Demaille <akim@epita.fr>
|

|
| + (b4_c_function_def): this.
|
| + (b4_c_function_decl, b4_c_ansi_function_def)
|
| + (b4_c_ansi_function_decl): New.
|
| + Change the interpretation of the arguments: before `int, foo', now
|
| + `int foo, foo'.
|
| + * data/yacc.c (yyparse): Prototype and define thanks to these.
|
| + Adjust b4_c_function_def uses.
|
| + * data/glr.c (yyparse): Likewise, but ANSI only.
|
| +
|
| +2002-10-20 Akim Demaille <akim@epita.fr>
|

|
| +
|
| + Do not create a temporary file, as that involves security and
|
| + cleanup headaches. Instead, use a pair of pipes.
|
| + Derived from a suggestion by Florian Krohm.
|
| + * lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files.
|
| + * lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove.
|

|
| + * src/scan-skel.l (readpipe): Remove decl.
|
| + (scan_skel): New function, to be used in place of m4_invoke.
|
| + Read from stream rather than file.
|
| +
|
| + * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
|
| + float, as this generates a warning on Solaris 8 + GCC 3.2 with
|
| + --enable-gcc-warnings. Instead, divide into 1.0 rather than 1;
|
| + this generates a more-accurate value anyway.
|
| +
|
| + * lib/timevar.c (timervar_accumulate): Rename locals to
|
| + avoid confusion with similarly-named more-global.
|
| + * src/muscle_tab.c (muscle_pair_list_grow): Likewise.
|
| +
|
| + * src/output.c (prepare): Use xstrdup to convert char const *

|
| +
|
| +2002-10-19 Akim Demaille <akim@epita.fr>
|
| +
|
| + * tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS,
|
| + LEX_PRE_FORMALS, LEX_ARGS, LEX_PRE_ARGS, USE_LEX_ARGS.
|
| + Use them to have `calc.y' ready for %pure-parser.

|
| +
|

|
| +
|

|

|
| +
|
| +2002-10-19 Akim Demaille <akim@epita.fr>
|

|
| + Report the traditional `Try ... --help' message when status != 0.
|
| + (usage, version): Don't take a FILE * as arg, it is pointless.
|
| + (getargs): When there is an incorrect number of arguments, make it
|
| + an error, and report it GNUlically thanks to `usage ()'.
|
| +
|
| +2002-10-18 Paul Eggert <eggert@twinsun.com>
|
| +
|
| + * data/glr.c (yyreportParseError): Don't assume that sprintf

|
| + on SunOS 4.1.4. Reported by Peter Klein.
|
| +
|
| + * tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc.

|
| + * src/reader.c (grammar_current_rule_prec_set)

|
| + And s/@prec/%prec/!
|
| + (reader): Use trace_flag to enable scanner/parser debugging,
|
| + instead of an adhoc scheme.
|

|
| +2002-10-16 Paul Eggert <eggert@twinsun.com>
|

|
| + Let nondeterministic skeletons be usable with deterministic

|
| +
|
| + With the patch, GAWK compiled by GCC without -O2 passes its test
|
| + suite using a GLR parser driven by LALR tables. It fails with -O2
|
| + because `struct stat' gives two different answers on my machine:
|
| + 88 (definition of an auto var) and later 96 (memset on this var).
|
| + Hence the stack is badly corrumpted. The headers inclusion is to
|
| + blame: if I move the awk.h inclusion before GLR's system header
|
| + inclusion, the two struct stat have the same size.

| + (which was a bug: it should have been YYTABEL_NINF, and yet it was
|
| + not satisfying as we could compare an YYACTION computed from

|
| + "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
|
| + because the Bison parser reads the second action before reducing

| + the first one.
|
| + * src/scan-gram.l (rule_length): New static var.
|
| + Use it to keep track of the rule length in the scanner, since

|

|
| +
|
| + Remove the support for C++ namespace cleanliness; it was

|
| + Give a try to M4 as a back end.
|
| +
|

|
| + BISON_HAIRY.
|
| + * src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS

|
| + Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.

|
| +2002-01-29 Paul Eggert <eggert@twinsun.com>
|

|

|
| +2002-01-27 Akim Demaille <akim@epita.fr>
|
| +
|
| + Fix `%nonassoc and eof'.

|
| +
|
| +2002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
|

|

|
| + * src/system.h: Use the canonical definition for PARAMS (avoids

|
| +2002-01-11 Akim Demaille <akim@epita.fr>

|
| + * lib/hash.h (__P): Added definition for this macro.
|
| + * src/Makefile.am: Add parse-skel.c and scan-skel.c to

|
| +2002-01-06 Akim Demaille <akim@epita.fr>
|

|
| +2002-01-06 Akim Demaille <akim@epita.fr>
|

|

| +
|
| +2002-01-03 Akim Demaille <akim@epita.fr>
|
| +
|
| + * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
|
| + The ISO C++ standard is extremely clear about it: stderr is
|
| + considered a macro, not a regular symbol (see table 94 `Header
|
| + <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
|
| + Therefore std:: does not apply to it. It still does with fprintf.
|
| + Also, s/cstdio.h/cstdio/.
|
| +
|
| +2002-01-03 Akim Demaille <akim@epita.fr>
|

|
| +2002-01-02 Akim Demaille <akim@epita.fr>
|
| +
|
| + Equip the skeleton chain with location tracking, runtime trace,
|
| + pure parser and scanner.
|
| +
|
| + * src/parse-skel.y: Request a pure parser, locations, and prefix

|
| + (%union): Having several members with the same type does not help

|
| + (YYPRINT, yyprint): New.
|
| + (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...

|
| +
|
| +2001-12-30 Akim Demaille <akim@epita.fr>
|
| +
|
| + * src/parse-skel.y: Get rid of the shift/reduce conflict:

|
| + * src/scan-skel.l: Adjust.
|
| +
|
| +2001-12-30 Akim Demaille <akim@epita.fr>
|
| +
|
| + * src/system.h: We don't need nor want bcopy.
|
| + Throw away MS-DOS crap: we don't need getpid.
|
| + * configure.in: We don't need strndup. It was even causing
|
| + problems: because Flex includes the headers *before* us,
|
| + _GNU_SOURCE is not defined by config.h, and therefore strndup was
|
| + not visible.
|
| + * lib/xstrndup.c: New.
|
| + * src/scan-skel.l: Use it.
|
| + Be sure to initialize yylval.muscle member when scanning a MUSCLE.
|
| + * src/parse-skel.y: Use %directives instead of #defines.

|

|
| + * src/output.h (get_lines_number, actions_output, guards_output)
|
| + (token_definitions_output): Prototype them.
|
| + * src/parse-skel.y: Add the license notice.
|

|
| + (process_skeleton): Returns void, and takes a single parameter.
|
| + * src/scan-skel.l: Add the license notice.
|
| + Include skeleton.h.
|
| + Don't use %option yylineno: it seems that then Flex imagines
|
| + REJECT has been used, and therefore it won't reallocate its
|
| + buffers (which makes no other sense to me than a bug). It results
|
| + in warnings for `unused: yy_flex_realloc'.

|
| + (MUSCLE_INSERT_PREFIX): Move from here...
|
| +
|
| + * src/bison.hairy: Add a section directive. Put braces around muscle
|
| + names. This parser skeleton is still broken, but Bison should not
|
| + choke on a bad muscle 'syntax'.
|
| + * src/bison.simple: Add a section directive. Put braces around muscle
|
| + names.
|
| +
|
| + * src/files.h (strsuffix, stringappend): Add declarations.
|
| + (tab_extension): Add declaration.
|
| + (short_base_name): Add declaration.
|
| +
|

|
| + * src/output.c (output_skeleton): New.

|

|
| + * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
|
| + Adjust all dependencies.
|
| + * tests/headers.at (export YYLTYPE): Strengthen this test: use
|
| + %name-prefix.
|
| +
|
| + Renaming yylval but not yylloc is not consistent. Now we do.
|
| +
|
| + * src/bison.simple: Prefix yylloc if used.
|
| + * doc/bison.texinfo (Decl Summary): Document that.
|
| +
|
| +2001-12-29 Akim Demaille <akim@epita.fr>
|
| +
|
| + * doc/bison.texinfo: Promote `%long-directive' over

|
| +
|
| +2001-12-29 Akim Demaille <akim@epita.fr>
|
| +
|

|
| +2001-12-29 Akim Demaille <akim@epita.fr>
|
| +

|

|

|
| +
|
| + * src/output.c (token_definitions_output): New.
|

|
| +
|
| +2001-12-29 Akim Demaille <akim@epita.fr>
|
| +
|
| + * src/bison.simple: Do not provide a default for YYSTYPE and

|
| + default.
|
| +
|
| +2001-12-29 Akim Demaille <akim@epita.fr>
|
| +
|
| + Mid-rule actions are simply... ignored!

|
| +
|
| + Memory leak.

|
| +
|
| +2001-12-29 Akim Demaille <akim@epita.fr>
|
| +
|
| + * tests/regression.at (Web2c Actions): Blindly move the actual
|
| + output as expected output. The contents *seem* right to me, but I
|
| + can't pretend reading perfectly parser tables... Nonetheless, all
|
| + the other tests pass correctly, the table look OK, even though the

|
| +
|
| +2001-12-29 Akim Demaille <akim@epita.fr>
|
| +
|
| + * src/reader.c (readgram): Don't add the rule 0 if there were no

|
| + grammar sanity checks.
|
| + Fixes the `tests/regression.at (Invalid input: 1)' Failure.
|
| +
|
| +2001-12-29 Akim Demaille <akim@epita.fr>
|
| +
|

|
| +2001-12-29 Akim Demaille <akim@epita.fr>
|

| +2001-12-29 Akim Demaille <akim@epita.fr>
|
| +
|
| + Fix the `GAWK Grammar' failure.
|
| +
|
| + * src/LR0.c (final_state): Initialize to -1 so that we do compute
|
| + the reductions of the first state which was mistakenly confused
|
| + with the final state because precisely final_state was initialized
|
| + to 0.
|
| + * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,

|
| + * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
|
| + have a reduction on $default.

| +
|
| + * src/lalr.c (lookaheads_print): New.

|
| +
|
| +2001-12-29 Akim Demaille <akim@epita.fr>
|
| +
|

|
| +2001-12-29 Akim Demaille <akim@epita.fr>
|

|
| +
|
| +2001-12-27 Paul Eggert <eggert@twinsun.com>
|
| +
|
| + * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
|
| + cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
|
| + Sparc, as they were causing more porting problems than the
|
| + (minor) performance improvement was worth.
|
| +
|
| + Also, catch up with 1.31's YYSTD.
|
| +
|
| +2001-12-27 Akim Demaille <akim@epita.fr>
|
| +
|
| + * src/output.c (output_gram): Rely on nritems, not the
|
| + 0-sentinel. See below.
|
| + Use -1 as separator, not 0.
|
| + * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
|
| + Rely on -1 as separator in yyrhs, instead of 0.
|
| + * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
|
| + twice `Now at end of input', therefore there are two lines less to
|
| + expect.
|
| +
|
| +2001-12-27 Akim Demaille <akim@epita.fr>
|
| +
|
| + * tests/regression.at (Unresolved SR Conflicts):

|
| + below.
|
| +
|
| +2001-12-27 Akim Demaille <akim@epita.fr>
|
| +
|
| + * src/LR0.c (new_state): Recognize the final state by the fact it
|
| + is reached by eoftoken.
|
| + (insert_start_shifting_state, insert_eof_shifting_state)
|
| + (insert_accepting_state, augment_automaton): Remove, since now
|
| + these states are automatically computed from the initial state.
|
| + (generate_states): Adjust.
|
| + * src/print.c: When reporting a rule number to the user, substract
|
| + 1, so that the axiom rule is rule 0, and the first user rule is 1.
|
| + * src/reduce.c: Likewise.
|
| + * src/print_graph.c (print_core): For the time being, just as for
|
| + the report, depend upon --trace-flags to dump the full set of
|
| + items.
|
| + * src/reader.c (readgram): Once the grammar read, insert the rule
|
| + 0: `$axiom: START-SYMBOL $'.
|
| + * tests/set.at: Adjust: rule 0 is now displayed, and since the
|
| + number of the states has changed (the final state is no longer
|
| + necessarily the last), catch up.
|
| +
|
| +2001-12-27 Akim Demaille <akim@epita.fr>
|
| +
|
| + Try to make the use of the eoftoken valid. Given that its value
|
| + is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
|
| + is used instead of > 0 where appropriate, (ii), depend upon nritems
|
| + instead of the 0-sentinel.
|
| +
|
| + * src/gram.h, src/gram.c (nritems): New.
|
| + Expected to be duplication of nitems, but for the time being...
|
| + * src/reader.c (packgram): Assert nritems and nitems are equal.
|
| + * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
|
| + * src/closure.c (print_closure, print_fderives): Likewise.

|
| +
|
| +2001-12-27 Akim Demaille <akim@epita.fr>
|
| +
|
| + * src/main.c (main): If there are complains after grammar
|

|
| + * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
|
| + * src/reader.c (eoftoken): New.
|
| + (parse_token_decl): If the token being defined has value `0', it
|
| + is the eoftoken.
|
| + (packsymbols): No longer hack `tags' to insert `$' by hand.
|
| + Be sure to preserve the value of the eoftoken.
|
| + (reader): Make sure eoftoken is defined.
|
| + Initialize nsyms to 0: now eoftoken is created just like the others.
|
| + * src/print.c (print_grammar): Don't special case the eof token.
|
| + * src/regression.at: Adjust: `$' has value 0, not -1, which was a
|
| + lie anyway, albeit pleasant.
|
| + * tests/calc.at: Exercise error messages with eoftoken.
|
| + Change the grammar so that empty input is invalid.
|
| + Adjust expectations.
|
| + When yyungeting, be sure to use a valid yylloc: use last_yylloc.
|
| +
|
| +2001-12-27 Akim Demaille <akim@epita.fr>
|
| +
|
| + * configure.in: Check the protos of strchr ans strspn.

|
| + Use it to quote the TAGS outputs.
|
| + * src/print_graph.c (print_state): Now errors are in red, and
|

|

| + (copy_action, copy_guard): these two which are renamed as...
|
| + (parse_action, parse_guard): these.
|
| + As a voluntary consequence, using braces around guards is now
|
| + mandatory.
|
| +
|
| +2001-12-27 Akim Demaille <akim@epita.fr>
|
| +
|
| + * src/gram.h (rule_t): `guard' and `guard_line' are new members.
|
| + * src/reader.c (symbol_list): `guard' and `guard_line' are new
|
| + members.
|
| + (symbol_list_new): Adjust.
|
| + (copy_action): action_line is the first line, not the last.
|
| + (copy_guard): Just as for actions, store the `action' only, not
|
| + the switch/case/break flesh.
|
| + Don't parse the user action that might follow the guard, let...
|
| + (readgram): do it, i.e., now, there can be an action after a
|
| + guard.
|
| + In other words the guard is just explicitly optional.
|
| + (packgram): Adjust.
|
| + * src/output.c (guards_output): New.
|
| + (output_parser): Call it when needed.
|
| + (output): Also free the guard and attrs obstacks.
|
| + * src/files.c, src/files.h (obstack_save): Remove.
|
| + (output_files): Remove.
|
| + As a result, if one needs the former `.act' file, using an
|
| + appropriate skeleton which requires actions and guards is now
|
| + required.
|
| + * src/main.c (main): Adjust.
|
| + * tests/semantic.at: New.
|
| + * tests/regression.at: Use `input.y' as input file name.
|
| + Avoid 8+3 problems by requiring input.c when the test needs the

|
| +2001-12-27 Akim Demaille <akim@epita.fr>
|

|
| + (conflicts_print, print_reductions): Use a state_t instead of an
|
| + integer when referring to a state.
|
| + As much as possible, depend upon nlookaheads, instead of the
|
| + `lookaheadsp' member of the following state (since lookaheads of
|
| + successive states are successive, the difference between state n + 1
|
| + and n served as the number of lookaheads for state n).
|

|
| + Use YYNTOKENS only, which is documented, but not YYNTBASE, which

|
| +2001-12-22 Akim Demaille <akim@epita.fr>
|

|
| + Reported by Nelson Beebee.
|

|

|
| +
|
| + * src/output.c (action_row, save_column, default_goto)

|

|
| +2001-12-17 Akim Demaille <akim@epita.fr>
|

|
| +2001-12-16 Marc Autret <autret_m@epita.fr>

|
| +2001-12-16 Marc Autret <autret_m@epita.fr>
|

|
| +2001-12-15 Marc Autret <autret_m@epita.fr>

|
| +2001-12-15 Akim Demaille <akim@epita.fr>
|
| +
|
| + Make `make distcheck' work.
|
| +
|
| + * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses

| + system.h which uses libgettext.h.
|
| +
|
| +2001-12-15 Akim Demaille <akim@epita.fr>
|
| +
|
| + * src/nullable.c (set_nullable): Useless rules must be skipped,
|
| + otherwise, since we range over their symbols, we might look at a
|
| + nonterminal which no longer ``exists'', i.e., it is not counted in
|
| + `nvars', hence we overflow our arrays.
|

|
| +2001-12-15 Akim Demaille <akim@epita.fr>
|
| +
|
| + The header can also be produced directly, without any obstack!
|

|
| + (compute_header_macro): Global.
|
| + (defines_obstack_save): Remove.
|
| + * src/reader.c (parse_union_decl): No longer output to

|
| +2001-12-15 Akim Demaille <akim@epita.fr>
|
| +
|
| + * src/reader.c (parse_union_decl): Instead of handling two obstack
|
| + simultaneously, use one to define the `stype' muscle, and use the
|
| + value of the latter to fill defines_obstack.
|
| + (copy_comment): Remove.
|

|
| +2001-12-15 Akim Demaille <akim@epita.fr>
|
| +
|
| + Still making progress in separating Bison into (i) input, (ii)
|

|
| +
|
| + * src/files.c, src/files.h (table_obstack): Bye bye.
|

|
| +
|
| +2001-12-15 Akim Demaille <akim@epita.fr>
|
| +
|
| + Attach actions to rules, instead of pre-outputting them to
|

|
| +
|

|
| + * src/reader.c (symbol_list): Likewise.
|
| + (copy_action): Save the actions within the rule.
|
| + (packgram): Save them in rule_table.

|

|

|
| + Suggested by Arnold Robbins and Tom Tromey.
|
| +
|
| +2001-12-14 Akim Demaille <akim@epita.fr>
|
| +
|

|
| + Adjust all callers.
|
| +
|
| +2001-12-14 Akim Demaille <akim@epita.fr>
|
| +
|
| + * src/lex.c (literalchar): Don't escape the special characters,
|
| + just decode them, and keep them as char (before, eol was output as
|
| + the 2 char string `\n' etc.).
|
| + * src/output.c (output_rule_data): Use quotearg to output the

|
| +
|
| +2001-12-13 Paul Eggert <eggert@twinsun.com>
|
| +
|
| + * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
|
| + Do not infringe on the global user namespace when using C++.
|
| + (YYFPRINTF, YYSTDERR): New macros, needed for the above.
|
| + All uses of `fprintf' and `stderr' changed.
|

|
| +
|
| +2001-12-13 Akim Demaille <akim@epita.fr>
|
| +
|
| + The computation of nullable is broken: it doesn't handle empty
|
| + RHS's properly.
|
| +
|
| + * tests/torture.at (GNU AWK Grammar): New.
|
| + * tests/sets.at (Nullable): New.
|
| + * src/nullable.c (set_nullable): Instead of blindly looping over
|
| + `ritems', loop over the rules, and then over their rhs's.
|
| +
|
| + Work around Autotest bugs.
|
| +
|
| + * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
|
| + frame, because Autotest understand lines starting with a `+' as
|
| + traces from the shell. Then, they are not processed properly.
|
| + Admittedly an Autotest bug, but we don't have time to wait for
|
| + Autotest to catch up.
|
| + * tests/regression.at (Broken Closure): Adjust to the new table
|
| + frames.
|
| + Move to...
|

|
| +
|
| +2001-12-13 Akim Demaille <akim@epita.fr>
|
| +
|
| + * src/print.c (print_actions): Output the handling of `$' as the
|
| + traces do: shifting the token EOF. Before EOF was treated as a
|
| + nonterminal.
|
| + * tests/regression.at: Adjust some tests.
|
| + * src/print_graph.c (print_core): Complete the set of items via
|
| + closure. The next-to-final and final states are still unsatisfying,
|
| + but that's to be addressed elsewhere.
|
| + No longer output the rule numbers, but do output the state number.
|
| + A single loop for the shifts + gotos is enough, but picked a
|
| + distinct color for each.
|
| + (print_graph): Initialize and finalize closure.
|
| +
|
| +2001-12-13 Akim Demaille <akim@epita.fr>
|

|
| +
|
| +2001-12-12 Akim Demaille <akim@epita.fr>
|

|
| +
|
| +2001-12-12 Akim Demaille <akim@epita.fr>
|
| +
|
| + Some hosts don't like `/' in includes.
|
| +
|
| + * src/system.h: Include libgettext.h without qualifying the path.
|
| + * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove

|
| +
|
| +2001-12-11 Marc Autret <autret_m@epita.fr>
|

|
| +
|
| +2001-12-11 Marc Autret <autret_m@epita.fr>
|
| +
|
| + * src/bison.simple: Remove #line just before %%epilogue. It
|
| + is now handled in ...
|
| + * src/reader.c (read_additionnal_code): Add the output of a
|
| + #line for the epilogue.
|
| +
|
| +2001-12-10 Marc Autret <autret_m@epita.fr>
|
| +
|

|

|
| +
|
| +2001-12-10 Akim Demaille <akim@epita.fr>
|
| +
|
| + * src/state.h (shifts): Remove the `number' member: shifts are

| + attached to state, hence no longer need to be labelled with a
|
| + state number.
|
| +
|
| +2001-12-10 Akim Demaille <akim@epita.fr>
|
| +
|
| + Now that states have a complete set of members, the linked list of

|

|
| + Adjust the callers.
|
| + (augment_automaton): Don't look for the shifts that must be added
|
| + a shift on EOF: it is those of the state we looked for! But now,
|
| + since shifts are attached, it is no longer needed to looking
|
| + merely by its id: its number.
|
| +
|
| +2001-12-10 Akim Demaille <akim@epita.fr>
|
| +
|
| + * src/LR0.c (augment_automaton): Better variable locality.
|
| + Remove an impossible branch: if there is a state corresponding to
|
| + the start symbol being shifted, then there is shift for the start
|
| + symbol from the initial state.
|
| +
|
| +2001-12-10 Akim Demaille <akim@epita.fr>
|
| +
|

|

|
| +2001-12-10 Akim Demaille <akim@epita.fr>

|

|

|

|

|
| + * src/LR0.c (insert_start_shift): Rename as...
|
| + (insert_start_shifting_state): this.
|
| + (insert_eof_shifting_state, insert_accepting_state): New.
|
| + (augment_automaton): Adjust.
|
| + Better locality of the variables.
|
| + When looking if the start_symbol is shifted from the initial
|
| + state, using `while (... symbol != start_symbol ...)' sounds
|
| + better than `while (... symbol < start_symbol ...)': If fail
|

|
| +
|
| +2001-12-10 Akim Demaille <akim@epita.fr>
|
| +
|
| + * src/getargs.h: Don't declare `spec_name_prefix' and

|
| +2001-12-10 Akim Demaille <akim@epita.fr>
|

|
| +2001-12-10 Akim Demaille <akim@epita.fr>
|

|

|
| +2001-12-10 Akim Demaille <akim@epita.fr>
|
| +
|
| + Now that states have a complete set of members, the linked list of

|
| + this_state.
|
| + * src/lalr.c (set_state_table): No need to attach reductions to
|
| + states, it's already done.
|
| + * src/output.c (output_actions): No longer free the shifts, then
|
| + the reductions, then the states: free all the states and their
|
| + members.

| +
|
| +2001-12-10 Akim Demaille <akim@epita.fr>
|
| +
|
| + * src/options.c (OPTN, DRTV, BOTH): New.
|
| + (option_table): Use them.
|
| +
|
| + * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
|
| + the job of system.h.
|
| + * src/options.c: Don't include stdio.h and xalloc.h for the same
|

|
| +
|
| +2001-12-10 Akim Demaille <akim@epita.fr>
|

|
| +
|
| + * src/reduce.c (reduce_grammar_tables): No longer disable the
|
| + removal of useless rules via CPP but via `if (0)', so that the
|
| + compiler still check the code is valid.
|
| + For instance, it should have noticed `rline' no longer exists: use

|

|

|
| +2001-12-05 Akim Demaille <akim@epita.fr>

|

|

|
| +2001-12-05 Akim Demaille <akim@epita.fr>

|

|
| +2001-12-05 Akim Demaille <akim@epita.fr>
|
| +
|
| + Because useless nonterminals are now kept alive (instead of being

|
| +
|

|
| + * src/LR0.c (allocate_itemsets): The memory allocated to

|
| + `shift_symbol', containing the symbol that can be shifted from a
|
| + given state.
|
| + Deobfuscate, i.e., allocate, use and free `symbol_count' here
|
| + only, and...
|
| + (new_itemsets): Allocate `shift_symbol' here.
|
| + (allocate_itemsets): symbol_count includes useless nonterminals.

|
| + * src/gram.c (dummy): Remove, now there is actual code in gram.c.
|
| + (This useless function was defined only to work around VMS linkers

|
| +

| +2001-11-30 Akim Demaille <akim@epita.fr>
|
| +
|

|
| + * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
|

|
| +2001-11-27 Paul Eggert <eggert@twinsun.com>

|
| + (SIZE_MAX, UINT_MAX): New macros.
|
| + (quotearg_n_options): Abort if N is negative.
|
| + Avoid overflow check on hosts where size_t is 64 bits and int

|
| +
|
| + (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing

|
| +
|
| + (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
|
| + Simplify test for whather <alloca.h> exists.
|

|
| +2001-11-30 Akim Demaille <akim@epita.fr>

|
| + prevents type checking.
|
| + (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't

|
| + (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.

| +2000-10-02 Paul Eggert <eggert@twinsun.com>
|

|

|
| +2000-10-02 Akim Demaille <akim@epita.fr>
|
| +
|
| + * src/getargs.c (getargs): Don't dump `--help' on unrecognized

|
| +2000-10-02 Akim Demaille <akim@epita.fr>
|
| +

|
| +
|
| +2000-10-02 Akim Demaille <akim@epita.fr>
|
| +
|
| + The location tracking mechanism is precious for parse error
|
| + messages. Nevertheless, it is enabled only when `@n' is used in
|
| + the grammar, which is a different issue (you can use it in error
|
| + message, but not in the grammar per se). Therefore, there should
|
| + be another means to enable it.
|
| +
|
| + * src/getargs.c (getargs): Support `--locations'.
|
| + (usage): Report it.
|
| + * src/getargs.h (locationsflag): Export it.

|
| + * src/reader.c (yylsp_needed): Remove this variable, now replaced
|
| + with `locationsflag'.
|
| + * doc/bison.texinfo: Document `--locations' and `%locations'.
|
| + Sort the options.
|
| + * tests/calc.m4: Test it.
|
| +
|
| + For regularity of the names, replace each
|
| + (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
|
| + (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
|
| + In addition replace each `flag' with `_flag'.
|
| +
|
| +2000-10-02 Akim Demaille <akim@epita.fr>
|
| +
|
| + Also test parse error messages, including with YYERROR_VERBOSE.
|
| +
|
| + * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
|
| + associative).
|
| + Use it to check the computations.
|
| + Use it to check `nonassoc' is honored.
|
| + (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
|
| + `--yyerror-verbose'.
|
| + (_AT_CHECK_CALC): Adjust to this option.
|

|
| +
|
| +2000-10-02 Akim Demaille <akim@epita.fr>
|
| +
|
| + Test also `--verbose', `--defines' and `--name-prefix'. Testing
|
| + the latter demonstrates a flaw in the handling of non debugging
|
| + parsers introduced by myself on 2000-03-16: `#define yydebug 0'
|
| + was used in order to simplify:
|
| +
|
| + #if YYDEBUG
|
| + if (yydebug)
|
| + {
|
| + ...
|
| + }
|
| + #endif
|

|
| + into
|
| +
|
| + if (yydebug)
|
| + {
|
| + ...
|
| + }
|
| +
|
| + unfortunately this leads to a CPP conflict when
|
| + `--name-prefix=foo' is used since it produces `#define yydebug
|
| + foodebug'.
|
| +
|
| + * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
|
| + (YYDPRINTF): New macro.
|

|

|
| +2000-10-02 Akim Demaille <akim@epita.fr>
|

|
| + Improve the readability of the produced parsers.
|

|
| + Improve the comment related to the `$' mark.
|

|
| + * src/output.c (output_parser): When the `$' is met, skip the end

|
| +
|
| + Use the more standard files `xalloc.h' and `xmalloc.c' instead of
|
| + Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
|
| + difficult and introduced a lot of core dump. It turns out that
|
| + Bison used an implementation of `xmalloc' based on `calloc', and
|
| + at various places it does depend upon the initialization to 0. I
|
| + have not tried to isolate the pertinent places, and all the former
|
| + calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
|
| + someone should address this issue.

| + printable_version to avoid unprintable characters in printed output.

| + always contain the token. This includes growing the token
|
| + buffer while reading an integer.
|
| + (parse_percent_token): Replaced if-else statement with percent_table.
|
| + (parse_percent_token): Added % declarations as another
|
| + way to specify the flags -n, -l, and -r. Also added hooks for
|
| + -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
|
| + major changes to files.c.
