61 You can use these macros to manipulate and query Valgrind's
62 execution inside your own programs.
63
64 The resulting executables will still run without Valgrind, just a
65 little bit more slowly than they otherwise would, but otherwise
66 unchanged. When not running on valgrind, each client request
67 consumes very few (eg. 7) instructions, so the resulting performance
68 loss is negligible unless you plan to execute client requests
69 millions of times per second. Nevertheless, if that is still a
70 problem, you can compile with the NVALGRIND symbol defined (gcc
71 -DNVALGRIND) so that client requests are not even compiled in. */

206 they will rot your brain.
207
208 The assembly code sequences for all architectures is in this one
209 file. This is because this file must be stand-alone, and we don't
210 want to have multiple files.
211
212 For VALGRIND_DO_CLIENT_REQUEST, we must ensure that the default
213 value gets put in the return slot, so that everything works when
214 this is executed not under Valgrind. Args are passed in a memory
215 block, and so there's no intrinsic limit to the number that could
216 be passed, but it's currently five.
217
218 The macro args are:
219 _zzq_rlval result lvalue
220 _zzq_default default value (result returned when running on real CPU)
221 _zzq_request request code
222 _zzq_arg1..5 request params
223
224 The other two macros are used to support function wrapping, and are
225 a lot simpler. VALGRIND_GET_NR_CONTEXT returns the value of the
226 guest's NRADDR pseudo-register and whatever other information is
227 needed to safely run the call original from the wrapper: on
228 ppc64-linux, the R2 value at the divert point is also needed. This
229 information is abstracted into a user-visible type, OrigFn.
230
231 VALGRIND_CALL_NOREDIR_* behaves the same as the following on the
232 guest, but guarantees that the branch instruction will not be
233 redirected: x86: call *%eax, amd64: call *%rax, ppc32/ppc64:
234 branch-and-link-to-r11. VALGRIND_CALL_NOREDIR is just text, not a
235 complete inline asm, since it needs to be combined with more magic
236 inline asm stuff to be useful.

1414 /* This is all pretty complex. It's so as to make stack unwinding
1415 work reliably. See bug 243270. The basic problem is the sub and
1416 add of 128 of %rsp in all of the following macros. If gcc believes
1417 the CFA is in %rsp, then unwinding may fail, because what's at the
1418 CFA is not what gcc "expected" when it constructs the CFIs for the
1419 places where the macros are instantiated.
1420
1421 But we can't just add a CFI annotation to increase the CFA offset
1422 by 128, to match the sub of 128 from %rsp, because we don't know
1423 whether gcc has chosen %rsp as the CFA at that point, or whether it
1424 has chosen some other register (eg, %rbp). In the latter case,
1425 adding a CFI annotation to change the CFA offset is simply wrong.
1426
1427 So the solution is to get hold of the CFA using
1428 __builtin_dwarf_cfa(), put it in a known register, and add a
1429 CFI annotation to say what the register is. We choose %rbp for
1430 this (perhaps perversely), because:
1431
1432 (1) %rbp is already subject to unwinding. If a new register was
1433 chosen then the unwinder would have to unwind it in all stack
1434 traces, which is expensive, and
1435
1436 (2) %rbp is already subject to precise exception updates in the
1437 JIT. If a new register was chosen, we'd have to have precise
1438 exceptions for it too, which reduces performance of the
1439 generated code.
1440
1441 However .. one extra complication. We can't just whack the result
1442 of __builtin_dwarf_cfa() into %rbp and then add %rbp to the
1443 list of trashed registers at the end of the inline assembly
1444 fragments; gcc won't allow %rbp to appear in that list. Hence
1445 instead we need to stash %rbp in %r15 for the duration of the asm,
1446 and say that %r15 is trashed instead. gcc seems happy to go with
1447 that.
1448
1449 Oh .. and this all needs to be conditionalised so that it is
1450 unchanged from before this commit, when compiled with older gccs
1451 that don't support __builtin_dwarf_cfa. Furthermore, since
1452 this header file is freestanding, it has to be independent of
1453 config.h, and so the following conditionalisation cannot depend on
1454 configure time checks.
1455
1456 Although it's not clear from
1457 'defined(__GNUC__) && defined(__GCC_HAVE_DWARF2_CFI_ASM)',
1458 this expression excludes Darwin.
1459 .cfi directives in Darwin assembly appear to be completely
1460 different and I haven't investigated how they work.
1461
1462 For even more entertainment value, note we have to use the
1463 completely undocumented __builtin_dwarf_cfa(), which appears to
1464 really compute the CFA, whereas __builtin_frame_address(0) claims
1465 to but actually doesn't. See
1466 https://bugs.kde.org/show_bug.cgi?id=243270#c47

1499 /* NB 9 Sept 07. There is a nasty kludge here in all these CALL_FN_
1500 macros. In order not to trash the stack redzone, we need to drop
1501 %rsp by 128 before the hidden call, and restore afterwards. The
1502 nastyness is that it is only by luck that the stack still appears
1503 to be unwindable during the hidden call - since then the behaviour
1504 of any routine using this macro does not match what the CFI data
1505 says. Sigh.
1506
1507 Why is this important? Imagine that a wrapper has a stack
1508 allocated local, and passes to the hidden call, a pointer to it.
1509 Because gcc does not know about the hidden call, it may allocate
1510 that local in the redzone. Unfortunately the hidden call may then
1511 trash it before it comes to use it. So we must step clear of the
1512 redzone, for the duration of the hidden call, to make it safe.
1513
1514 Probably the same problem afflicts the other redzone-style ABIs too
1515 (ppc64-linux); but for those, the stack is
1516 self describing (none of this CFI nonsense) so at least messing
1517 with the stack pointer doesn't give a danger of non-unwindable
1518 stack. */

5181 /* Several Valgrind tools (Memcheck, Massif, Helgrind, DRD) rely on knowing
5182 when heap blocks are allocated in order to give accurate results. This
5183 happens automatically for the standard allocator functions such as
5184 malloc(), calloc(), realloc(), memalign(), new, new[], free(), delete,
5185 delete[], etc.
5186
5187 But if your program uses a custom allocator, this doesn't automatically
5188 happen, and Valgrind will not do as well. For example, if you allocate
5189 superblocks with mmap() and then allocates chunks of the superblocks, all
5190 Valgrind's observations will be at the mmap() level and it won't know that
5191 the chunks should be considered separate entities. In Memcheck's case,
5192 that means you probably won't get heap block overrun detection (because
5193 there won't be redzones marked as unaddressable) and you definitely won't
5194 get any leak detection.
5195
5196 The following client requests allow a custom allocator to be annotated so
5197 that it can be handled accurately by Valgrind.
5198
5199 VALGRIND_MALLOCLIKE_BLOCK marks a region of memory as having been allocated
5200 by a malloc()-like function. For Memcheck (an illustrative case), this
5201 does two things:
5202
5203 - It records that the block has been allocated. This means any addresses
5204 within the block mentioned in error messages will be
5205 identified as belonging to the block. It also means that if the block
5206 isn't freed it will be detected by the leak checker.
5207
5208 - It marks the block as being addressable and undefined (if 'is_zeroed' is
5209 not set), or addressable and defined (if 'is_zeroed' is set). This
5210 controls how accesses to the block by the program are handled.
5211
5212 'addr' is the start of the usable block (ie. after any
5213 redzone), 'sizeB' is its size. 'rzB' is the redzone size if the allocator
5214 can apply redzones -- these are blocks of padding at the start and end of
5215 each block. Adding redzones is recommended as it makes it much more likely
5216 Valgrind will spot block overruns. `is_zeroed' indicates if the memory is
5217 zeroed (or filled with another predictable value), as is the case for
5218 calloc().
5219
5220 VALGRIND_MALLOCLIKE_BLOCK should be put immediately after the point where a
5221 heap block -- that will be used by the client program -- is allocated.
5222 It's best to put it at the outermost level of the allocator if possible;
5223 for example, if you have a function my_alloc() which calls
5224 internal_alloc(), and the client request is put inside internal_alloc(),
5225 stack traces relating to the heap block will contain entries for both
5226 my_alloc() and internal_alloc(), which is probably not what you want.
5227
5228 For Memcheck users: if you use VALGRIND_MALLOCLIKE_BLOCK to carve out
5229 custom blocks from within a heap block, B, that has been allocated with
5230 malloc/calloc/new/etc, then block B will be *ignored* during leak-checking
5231 -- the custom blocks will take precedence.
5232
5233 VALGRIND_FREELIKE_BLOCK is the partner to VALGRIND_MALLOCLIKE_BLOCK. For
5234 Memcheck, it does two things:
5235
5236 - It records that the block has been deallocated. This assumes that the
5237 block was annotated as having been allocated via
5238 VALGRIND_MALLOCLIKE_BLOCK. Otherwise, an error will be issued.
5239
5240 - It marks the block as being unaddressable.
5241
5242 VALGRIND_FREELIKE_BLOCK should be put immediately after the point where a
5243 heap block is deallocated.
5244
5245 VALGRIND_RESIZEINPLACE_BLOCK informs a tool about reallocation. For
5246 Memcheck, it does four things:
5247
5248 - It records that the size of a block has been changed. This assumes that
5249 the block was annotated as having been allocated via
5250 VALGRIND_MALLOCLIKE_BLOCK. Otherwise, an error will be issued.
5251
5252 - If the block shrunk, it marks the freed memory as being unaddressable.
5253
5254 - If the block grew, it marks the new area as undefined and defines a red
5255 zone past the end of the new block.
5256
5257 - The V-bits of the overlap between the old and the new block are preserved.
5258
5259 VALGRIND_RESIZEINPLACE_BLOCK should be put after allocation of the new block
5260 and before deallocation of the old block.
5261
5262 In many cases, these three client requests will not be enough to get your
5263 allocator working well with Memcheck. More specifically, if your allocator
5264 writes to freed blocks in any way then a VALGRIND_MAKE_MEM_UNDEFINED call
5265 will be necessary to mark the memory as addressable just before the zeroing
5266 occurs, otherwise you'll get a lot of invalid write errors. For example,
5267 you'll need to do this if your allocator recycles freed blocks, but it
5268 zeroes them before handing them back out (via VALGRIND_MALLOCLIKE_BLOCK).
5269 Alternatively, if your allocator reuses freed blocks for allocator-internal
5270 data structures, VALGRIND_MAKE_MEM_UNDEFINED calls will also be necessary.
5271
5272 Really, what's happening is a blurring of the lines between the client
5273 program and the allocator... after VALGRIND_FREELIKE_BLOCK is called, the
5274 memory should be considered unaddressable to the client program, but the
5275 allocator knows more than the rest of the client program and so may be able
5276 to safely access it. Extra client requests are necessary for Valgrind to
5277 understand the distinction between the allocator and the rest of the
5278 program.
