| 140 _zzq_rlval, _zzq_default, _zzq_request, \ |
| 141 _zzq_arg1, _zzq_arg2, _zzq_arg3, _zzq_arg4, _zzq_arg5) \ |

| 148 /* The following defines the magic code sequences which the JITter |
| 149 spots and handles magically. Don't look too closely at them as |
| 150 they will rot your brain. |
| 151 |
| 152 The assembly code sequences for all architectures is in this one |
| 153 file. This is because this file must be stand-alone, and we don't |
| 154 want to have multiple files. |
| 155 |
| 156 For VALGRIND_DO_CLIENT_REQUEST, we must ensure that the default |
| 157 value gets put in the return slot, so that everything works when |
| 158 this is executed not under Valgrind. Args are passed in a memory |
| 159 block, and so there's no intrinsic limit to the number that could |
| 160 be passed, but it's currently five. |
| 161 |
| 162 The macro args are: |
| 163 _zzq_rlval result lvalue |
| 164 _zzq_default default value (result returned when running on real CPU) |
| 165 _zzq_request request code |
| 166 _zzq_arg1..5 request params |
| 167 |
| 168 The other two macros are used to support function wrapping, and are |
| 169 a lot simpler. VALGRIND_GET_NR_CONTEXT returns the value of the |
| 170 guest's NRADDR pseudo-register and whatever other information is |
| 171 needed to safely run the call original from the wrapper: on |
| 172 ppc64-linux, the R2 value at the divert point is also needed. This |
| 173 information is abstracted into a user-visible type, OrigFn. |
| 174 |
| 175 VALGRIND_CALL_NOREDIR_* behaves the same as the following on the |
| 176 guest, but guarantees that the branch instruction will not be |
| 177 redirected: x86: call *%eax, amd64: call *%rax, ppc32/ppc64: |
| 178 branch-and-link-to-r11. VALGRIND_CALL_NOREDIR is just text, not a |
| 179 complete inline asm, since it needs to be combined with more magic |
| 180 inline asm stuff to be useful. |

| 1112 /* NB 9 Sept 07. There is a nasty kludge here in all these CALL_FN_ |
| 1113 macros. In order not to trash the stack redzone, we need to drop |
| 1114 %rsp by 128 before the hidden call, and restore afterwards. The |
| 1115 nastyness is that it is only by luck that the stack still appears |
| 1116 to be unwindable during the hidden call - since then the behaviour |
| 1117 of any routine using this macro does not match what the CFI data |
| 1118 says. Sigh. |
| 1119 |
| 1120 Why is this important? Imagine that a wrapper has a stack |
| 1121 allocated local, and passes to the hidden call, a pointer to it. |
| 1122 Because gcc does not know about the hidden call, it may allocate |
| 1123 that local in the redzone. Unfortunately the hidden call may then |
| 1124 trash it before it comes to use it. So we must step clear of the |
| 1125 redzone, for the duration of the hidden call, to make it safe. |
| 1126 |
| 1127 Probably the same problem afflicts the other redzone-style ABIs too |
| 1128 (ppc64-linux, ppc32-aix5, ppc64-aix5); but for those, the stack is |
| 1129 self describing (none of this CFI nonsense) so at least messing |
| 1130 with the stack pointer doesn't give a danger of non-unwindable |
| 1131 stack. */ |

| 4305 happens automatically for the standard allocator functions such as |
| 4306 malloc(), calloc(), realloc(), memalign(), new, new[], free(), delete, |
| 4307 delete[], etc. |
| 4308 |
| 4309 But if your program uses a custom allocator, this doesn't automatically |
| 4310 happen, and Valgrind will not do as well. For example, if you allocate |
| 4311 superblocks with mmap() and then allocates chunks of the superblocks, all |
| 4312 Valgrind's observations will be at the mmap() level and it won't know that |
| 4313 the chunks should be considered separate entities. In Memcheck's case, |
| 4314 that means you probably won't get heap block overrun detection (because |
| 4315 there won't be redzones marked as unaddressable) and you definitely won't |
| 4316 get any leak detection. |
| 4317 |
| 4318 The following client requests allow a custom allocator to be annotated so |
| 4319 that it can be handled accurately by Valgrind. |
| 4320 |
| 4321 VALGRIND_MALLOCLIKE_BLOCK marks a region of memory as having been allocated |
| 4322 by a malloc()-like function. For Memcheck (an illustrative case), this |
| 4323 does two things: |
| 4324 |
| 4325 - It records that the block has been allocated. This means any addresses |
| 4326 within the block mentioned in error messages will be |
| 4327 identified as belonging to the block. It also means that if the block |
| 4328 isn't freed it will be detected by the leak checker. |
| 4329 |
| 4330 - It marks the block as being addressable and undefined (if 'is_zeroed' is |
| 4331 not set), or addressable and defined (if 'is_zeroed' is set). This |
| 4332 controls how accesses to the block by the program are handled. |
| 4333 |
| 4334 'addr' is the start of the usable block (ie. after any |
| 4335 redzone), 'sizeB' is its size. 'rzB' is the redzone size if the allocator |
| 4336 can apply redzones -- these are blocks of padding at the start and end of |
| 4337 each block. Adding redzones is recommended as it makes it much more likely |
| 4338 Valgrind will spot block overruns. `is_zeroed' indicates if the memory is |
| 4339 zeroed (or filled with another predictable value), as is the case for |
| 4340 calloc(). |
| 4341 |
| 4342 VALGRIND_MALLOCLIKE_BLOCK should be put immediately after the point where a |
| 4343 heap block -- that will be used by the client program -- is allocated. |
| 4344 It's best to put it at the outermost level of the allocator if possible; |
| 4345 for example, if you have a function my_alloc() which calls |
| 4346 internal_alloc(), and the client request is put inside internal_alloc(), |
| 4347 stack traces relating to the heap block will contain entries for both |
| 4348 my_alloc() and internal_alloc(), which is probably not what you want. |
| 4349 |
| 4350 For Memcheck users: if you use VALGRIND_MALLOCLIKE_BLOCK to carve out |
| 4351 custom blocks from within a heap block, B, that has been allocated with |
| 4352 malloc/calloc/new/etc, then block B will be *ignored* during leak-checking |
| 4353 -- the custom blocks will take precedence. |
| 4354 |
| 4355 VALGRIND_FREELIKE_BLOCK is the partner to VALGRIND_MALLOCLIKE_BLOCK. For |
| 4356 Memcheck, it does two things: |
| 4357 |
| 4358 - It records that the block has been deallocated. This assumes that the |
| 4359 block was annotated as having been allocated via |
| 4360 VALGRIND_MALLOCLIKE_BLOCK. Otherwise, an error will be issued. |
| 4361 |
| 4362 - It marks the block as being unaddressable. |
| 4363 |
| 4364 VALGRIND_FREELIKE_BLOCK should be put immediately after the point where a |
| 4365 heap block is deallocated. |
| 4366 |
| 4367 In many cases, these two client requests will not be enough to get your |
| 4368 allocator working well with Memcheck. More specifically, if your allocator |
| 4369 writes to freed blocks in any way then a VALGRIND_MAKE_MEM_UNDEFINED call |
| 4370 will be necessary to mark the memory as addressable just before the zeroing |
| 4371 occurs, otherwise you'll get a lot of invalid write errors. For example, |
| 4372 you'll need to do this if your allocator recycles freed blocks, but it |
| 4373 zeroes them before handing them back out (via VALGRIND_MALLOCLIKE_BLOCK). |
| 4374 Alternatively, if your allocator reuses freed blocks for allocator-internal |
| 4375 data structures, VALGRIND_MAKE_MEM_UNDEFINED calls will also be necessary. |
| 4376 |
| 4377 Really, what's happening is a blurring of the lines between the client |
| 4378 program and the allocator... after VALGRIND_FREELIKE_BLOCK is called, the |
| 4379 memory should be considered unaddressable to the client program, but the |
| 4380 allocator knows more than the rest of the client program and so may be able |
| 4381 to safely access it. Extra client requests are necessary for Valgrind to |
| 4382 understand the distinction between the allocator and the rest of the |
| 4383 program. |
| 4384 |
| 4385 Note: there is currently no VALGRIND_REALLOCLIKE_BLOCK client request; it |
| 4386 has to be emulated with MALLOCLIKE/FREELIKE and memory copying. |
