+/* Timing variables are used to measure elapsed time in various
+   portions of the compiler.  Each measures elapsed user, system, and
+   wall-clock time, as appropriate to and supported by the host
+   system.
+
+   Timing variables are defined using the DEFTIMEVAR macro in
+   timevar.def.  Each has an enumeral identifier, used when referring
+   to the timing variable in code, and a character string name.
+
+   Timing variables can be used in two ways:
+
+     - On the timing stack, using timevar_push and timevar_pop.
+       Timing variables may be pushed onto the stack; elapsed time is
+       attributed to the topmost timing variable on the stack.  When
+       another variable is pushed on, the previous topmost variable is
+       `paused' until the pushed variable is popped back off.
+
+     - As a standalone timer, using timevar_start and timevar_stop.
+       All time elapsed between the two calls is attributed to the
+       variable.

+
+/* This structure stores the various varieties of time that can be
+   measured.  Times are stored in seconds.  The time may be an
+   absolute time or a time difference; in the former case, the time
+   base is undefined, except that the difference between two times
+   produces a valid time difference.  */
