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.

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. */ 1132 1133 #define CALL_FN_W_v(lval, orig) \ 1134 do { \ 1135 volatile OrigFn _orig = (orig);

This 4306 happens automatically for the standard allocator functions such as 4307 malloc(), calloc(), realloc(), memalign(), new, new[], free(), delete, 4308 delete[], etc. 4309 4310 But if your program uses a custom allocator, this doesn't automatically 4311 happen, and Valgrind will not do as well. For example, if you allocate 4312 superblocks with mmap() and then allocates chunks of the superblocks, all 4313 Valgrind's observations will be at the mmap() level and it won't know that 4314 the chunks should be considered separate entities. In Memcheck's case, 4315 that means you probably won't get heap block overrun detection (because 4316 there won't be redzones marked as unaddressable) and you definitely won't 4317 get any leak detection. 4318 4319 The following client requests allow a custom allocator to be annotated so 4320 that it can be handled accurately by Valgrind. 4321 4322 VALGRIND_MALLOCLIKE_BLOCK marks a region of memory as having been allocated 4323 by a malloc()-like function. For Memcheck (an illustrative case), this 4324 does two things: 4325 4326 - It records that the block has been allocated. This means any addresses 4327 within the block mentioned in error messages will be 4328 identified as belonging to the block. It also means that if the block 4329 isn't freed it will be detected by the leak checker. 4330 4331 - It marks the block as being addressable and undefined (if 'is_zeroed' is 4332 not set), or addressable and defined (if 'is_zeroed' is set). This 4333 controls how accesses to the block by the program are handled. 4334 4335 'addr' is the start of the usable block (ie. after any 4336 redzone), 'sizeB' is its size. 'rzB' is the redzone size if the allocator 4337 can apply redzones -- these are blocks of padding at the start and end of 4338 each block. Adding redzones is recommended as it makes it much more likely 4339 Valgrind will spot block overruns. `is_zeroed' indicates if the memory is 4340 zeroed (or filled with another predictable value), as is the case for 4341 calloc(). 4342 4343 VALGRIND_MALLOCLIKE_BLOCK should be put immediately after the point where a 4344 heap block -- that will be used by the client program -- is allocated. 4345 It's best to put it at the outermost level of the allocator if possible; 4346 for example, if you have a function my_alloc() which calls 4347 internal_alloc(), and the client request is put inside internal_alloc(), 4348 stack traces relating to the heap block will contain entries for both 4349 my_alloc() and internal_alloc(), which is probably not what you want. 4350 4351 For Memcheck users: if you use VALGRIND_MALLOCLIKE_BLOCK to carve out 4352 custom blocks from within a heap block, B, that has been allocated with 4353 malloc/calloc/new/etc, then block B will be *ignored* during leak-checking 4354 -- the custom blocks will take precedence. 4355 4356 VALGRIND_FREELIKE_BLOCK is the partner to VALGRIND_MALLOCLIKE_BLOCK. For 4357 Memcheck, it does two things: 4358 4359 - It records that the block has been deallocated. This assumes that the 4360 block was annotated as having been allocated via 4361 VALGRIND_MALLOCLIKE_BLOCK. Otherwise, an error will be issued. 4362 4363 - It marks the block as being unaddressable. 4364 4365 VALGRIND_FREELIKE_BLOCK should be put immediately after the point where a 4366 heap block is deallocated. 4367 4368 In many cases, these two client requests will not be enough to get your 4369 allocator working well with Memcheck. More specifically, if your allocator 4370 writes to freed blocks in any way then a VALGRIND_MAKE_MEM_UNDEFINED call 4371 will be necessary to mark the memory as addressable just before the zeroing 4372 occurs, otherwise you'll get a lot of invalid write errors. For example, 4373 you'll need to do this if your allocator recycles freed blocks, but it 4374 zeroes them before handing them back out (via VALGRIND_MALLOCLIKE_BLOCK). 4375 Alternatively, if your allocator reuses freed blocks for allocator-internal 4376 data structures, VALGRIND_MAKE_MEM_UNDEFINED calls will also be necessary. 4377 4378 Really, what's happening is a blurring of the lines between the client 4379 program and the allocator... after VALGRIND_FREELIKE_BLOCK is called, the 4380 memory should be considered unaddressable to the client program, but the 4381 allocator knows more than the rest of the client program and so may be able 4382 to safely access it. Extra client requests are necessary for Valgrind to 4383 understand the distinction between the allocator and the rest of the 4384 program. 4385 4386 Note: there is currently no VALGRIND_REALLOCLIKE_BLOCK client request; it 4387 has to be emulated with MALLOCLIKE/FREELIKE and memory copying. 4388 4389 Ignored if addr == 0. 4390 */ 4391 #define VALGRIND_MALLOCLIKE_BLOCK(addr, sizeB, rzB, is_zeroed) \ 4392 {unsigned int _qzz_res; \ 4393 VALGRIND_DO_CLIENT_REQUEST(_qzz_res, 0, \ 4394 VG_USERREQ__MALLOCLIKE_BLOCK, \ 4395 addr, sizeB, rzB, is_zeroed, 0); \ 4396 } 4397 4398 /* See the comment for VALGRIND_MALLOCLIKE_BLOCK for details. 4399 Ignored if addr == 0. 4400 */ 4401 #define VALGRIND_FREELIKE_BLOCK(addr, rzB) \ 4402 {unsigned int _qzz_res; \ 4403 VALGRIND_DO_CLIENT_REQUEST(_qzz_res, 0, \ 4404 VG_USERREQ__FREELIKE_BLOCK, \ 4405 addr, rzB, 0, 0, 0); \ 4406 } 4407 4408 /* Create a memory pool. */ 4409 #define VALGRIND_CREATE_MEMPOOL(pool, rzB, is_zeroed) \ 4410 {unsigned int _qzz_res; \ 4411 VALGRIND_DO_CLIENT_REQUEST(_qzz_res, 0, \ 4412 VG_USERREQ__CREATE_MEMPOOL, \ 4413 pool, rzB, is_zeroed, 0, 0); \ 4414 } 4415 4416 /* Destroy a memory pool. */ 4417 #define VALGRIND_DESTROY_MEMPOOL(pool) \ 4418 {unsigned int _qzz_res; \ 4419 VALGRIND_DO_CLIENT_REQUEST(_qzz_res, 0, \ 4420 VG_USERREQ__DESTROY_MEMPOOL, \ 4421 pool, 0, 0, 0, 0); \ 4422 } 4423 4424 /* Associate a piece of memory with a memory pool. */ 4425 #define VALGRIND_MEMPOOL_ALLOC(pool, addr, size) \ 4426 {unsigned int _qzz_res; \ 4427 VALGRIND_DO_CLIENT_REQUEST(_qzz_res, 0, \ 4428 VG_USERREQ__MEMPOOL_ALLOC, \ 4429 pool, addr, size, 0, 0); \ 4430 } 4431 4432 /* Disassociate a piece of memory from a memory pool. */ 4433 #define VALGRIND_MEMPOOL_FREE(pool, addr) \ 4434 {unsigned int _qzz_res; \ 4435 VALGRIND_DO_CLIENT_REQUEST(_qzz_res, 0, \ 4436 VG_USERREQ__MEMPOOL_FREE, \ 4437 pool, addr, 0, 0, 0); \ 4438 } 4439 4440 /* Disassociate any pieces outside a particular range. */ 4441 #define VALGRIND_MEMPOOL_TRIM(pool, addr, size) \ 4442 {unsigned int _qzz_res; \ 4443 VALGRIND_DO_CLIENT_REQUEST(_qzz_res, 0, \ 4444 VG_USERREQ__MEMPOOL_TRIM, \ 4445 pool, addr, size, 0, 0); \ 4446 } 4447 4448 /* Resize and/or move a piece associated with a memory pool. */ 4449 #define VALGRIND_MOVE_MEMPOOL(poolA, poolB) \ 4450 {unsigned int _qzz_res; \ 4451 VALGRIND_DO_CLIENT_REQUEST(_qzz_res, 0, \ 4452 VG_USERREQ__MOVE_MEMPOOL, \ 4453 poolA, poolB, 0, 0, 0); \ 4454 } 4455 4456 /* Resize and/or move a piece associated with a memory pool. */ 4457 #define VALGRIND_MEMPOOL_CHANGE(pool, addrA, addrB, size) \ 4458 {unsigned int _qzz_res; \ 4459 VALGRIND_DO_CLIENT_REQUEST(_qzz_res, 0, \ 4460 VG_USERREQ__MEMPOOL_CHANGE, \ 4461 pool, addrA, addrB, size, 0); \ 4462 } 4463 4464 /* Return 1 if a mempool exists, else 0. */ 4465 #define VALGRIND_MEMPOOL_EXISTS(pool) \ 4466 __extension__ \ 4467 ({unsigned int _qzz_res; \ 4468 VALGRIND_DO_CLIENT_REQUEST(_qzz_res, 0, \ 4469 VG_USERREQ__MEMPOOL_EXISTS, \ 4470 pool, 0, 0, 0, 0); \ 4471 _qzz_res; \ 4472 }) 4473 4474 /* Mark a piece of memory as being a stack.
