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. */

220 they will rot your brain.
221
222 The assembly code sequences for all architectures is in this one
223 file. This is because this file must be stand-alone, and we don't
224 want to have multiple files.
225
226 For VALGRIND_DO_CLIENT_REQUEST, we must ensure that the default
227 value gets put in the return slot, so that everything works when
228 this is executed not under Valgrind. Args are passed in a memory
229 block, and so there's no intrinsic limit to the number that could
230 be passed, but it's currently five.
231
232 The macro args are:
233 _zzq_rlval result lvalue
234 _zzq_default default value (result returned when running on real CPU)
235 _zzq_request request code
236 _zzq_arg1..5 request params
237
238 The other two macros are used to support function wrapping, and are
239 a lot simpler. VALGRIND_GET_NR_CONTEXT returns the value of the
240 guest's NRADDR pseudo-register and whatever other information is
241 needed to safely run the call original from the wrapper: on
242 ppc64-linux, the R2 value at the divert point is also needed. This
243 information is abstracted into a user-visible type, OrigFn.
244
245 VALGRIND_CALL_NOREDIR_* behaves the same as the following on the
246 guest, but guarantees that the branch instruction will not be
247 redirected: x86: call *%eax, amd64: call *%rax, ppc32/ppc64:
248 branch-and-link-to-r11. VALGRIND_CALL_NOREDIR is just text, not a
249 complete inline asm, since it needs to be combined with more magic
250 inline asm stuff to be useful.

1059 guaranteed-no-redirection macros, so as to get from function
1060 wrappers to the functions they are wrapping. The whole point is to
1061 construct standard call sequences, but to do the call itself with a
1062 special no-redirect call pseudo-instruction that the JIT
1063 understands and handles specially. This section is long and
1064 repetitious, and I can't see a way to make it shorter.

1068 CALL_FN_{W,v}_{v,W,WW,WWW,WWWW,5W,6W,7W,etc}

1070 'W' stands for "word" and 'v' for "void". Hence there are
1071 different macros for calling arity 0, 1, 2, 3, 4, etc, functions,
1072 and for each, the possibility of returning a word-typed result, or
1073 no result.

1588 /* This is all pretty complex. It's so as to make stack unwinding
1589 work reliably. See bug 243270. The basic problem is the sub and
1590 add of 128 of %rsp in all of the following macros. If gcc believes
1591 the CFA is in %rsp, then unwinding may fail, because what's at the
1592 CFA is not what gcc "expected" when it constructs the CFIs for the
1593 places where the macros are instantiated.
1594
1595 But we can't just add a CFI annotation to increase the CFA offset
1596 by 128, to match the sub of 128 from %rsp, because we don't know
1597 whether gcc has chosen %rsp as the CFA at that point, or whether it
1598 has chosen some other register (eg, %rbp). In the latter case,
1599 adding a CFI annotation to change the CFA offset is simply wrong.
1600
1601 So the solution is to get hold of the CFA using
1602 __builtin_dwarf_cfa(), put it in a known register, and add a
1603 CFI annotation to say what the register is. We choose %rbp for
1604 this (perhaps perversely), because:
1605
1606 (1) %rbp is already subject to unwinding. If a new register was
1607 chosen then the unwinder would have to unwind it in all stack
1608 traces, which is expensive, and
1609
1610 (2) %rbp is already subject to precise exception updates in the
1611 JIT. If a new register was chosen, we'd have to have precise
1612 exceptions for it too, which reduces performance of the
1613 generated code.
1614
1615 However .. one extra complication. We can't just whack the result
1616 of __builtin_dwarf_cfa() into %rbp and then add %rbp to the
1617 list of trashed registers at the end of the inline assembly
1618 fragments; gcc won't allow %rbp to appear in that list. Hence
1619 instead we need to stash %rbp in %r15 for the duration of the asm,
1620 and say that %r15 is trashed instead. gcc seems happy to go with
1621 that.
1622
1623 Oh .. and this all needs to be conditionalised so that it is
1624 unchanged from before this commit, when compiled with older gccs
1625 that don't support __builtin_dwarf_cfa. Furthermore, since
1626 this header file is freestanding, it has to be independent of
1627 config.h, and so the following conditionalisation cannot depend on
1628 configure time checks.
1629
1630 Although it's not clear from
1631 'defined(__GNUC__) && defined(__GCC_HAVE_DWARF2_CFI_ASM)',
1632 this expression excludes Darwin.
1633 .cfi directives in Darwin assembly appear to be completely
1634 different and I haven't investigated how they work.
1635
1636 For even more entertainment value, note we have to use the
1637 completely undocumented __builtin_dwarf_cfa(), which appears to
1638 really compute the CFA, whereas __builtin_frame_address(0) claims
1639 to but actually doesn't. See
1640 https://bugs.kde.org/show_bug.cgi?id=243270#c47

1673 /* NB 9 Sept 07. There is a nasty kludge here in all these CALL_FN_
1674 macros. In order not to trash the stack redzone, we need to drop
1675 %rsp by 128 before the hidden call, and restore afterwards. The
1676 nastiness is that it is only by luck that the stack still appears
1677 to be unwindable during the hidden call - since then the behaviour
1678 of any routine using this macro does not match what the CFI data
1679 says. Sigh.
1680
1681 Why is this important? Imagine that a wrapper has a stack
1682 allocated local, and passes to the hidden call, a pointer to it.
1683 Because gcc does not know about the hidden call, it may allocate
1684 that local in the redzone. Unfortunately the hidden call may then
1685 trash it before it comes to use it. So we must step clear of the
1686 redzone, for the duration of the hidden call, to make it safe.
1687
1688 Probably the same problem afflicts the other redzone-style ABIs too
1689 (ppc64-linux); but for those, the stack is
1690 self describing (none of this CFI nonsense) so at least messing
1691 with the stack pointer doesn't give a danger of non-unwindable
1692 stack. */

6376 /* Several Valgrind tools (Memcheck, Massif, Helgrind, DRD) rely on knowing
6377 when heap blocks are allocated in order to give accurate results. This
6378 happens automatically for the standard allocator functions such as
6379 malloc(), calloc(), realloc(), memalign(), new, new[], free(), delete,
6380 delete[], etc.
6381
6382 But if your program uses a custom allocator, this doesn't automatically
6383 happen, and Valgrind will not do as well. For example, if you allocate
6384 superblocks with mmap() and then allocates chunks of the superblocks, all
6385 Valgrind's observations will be at the mmap() level and it won't know that
6386 the chunks should be considered separate entities. In Memcheck's case,
6387 that means you probably won't get heap block overrun detection (because
6388 there won't be redzones marked as unaddressable) and you definitely won't
6389 get any leak detection.
6390
6391 The following client requests allow a custom allocator to be annotated so
6392 that it can be handled accurately by Valgrind.
6393
6394 VALGRIND_MALLOCLIKE_BLOCK marks a region of memory as having been allocated
6395 by a malloc()-like function. For Memcheck (an illustrative case), this
6396 does two things:
6397
6398 - It records that the block has been allocated. This means any addresses
6399 within the block mentioned in error messages will be
6400 identified as belonging to the block. It also means that if the block
6401 isn't freed it will be detected by the leak checker.
6402
6403 - It marks the block as being addressable and undefined (if 'is_zeroed' is
6404 not set), or addressable and defined (if 'is_zeroed' is set). This
6405 controls how accesses to the block by the program are handled.
6406
6407 'addr' is the start of the usable block (ie. after any
6408 redzone), 'sizeB' is its size. 'rzB' is the redzone size if the allocator
6409 can apply redzones -- these are blocks of padding at the start and end of
6410 each block. Adding redzones is recommended as it makes it much more likely
6411 Valgrind will spot block overruns. `is_zeroed' indicates if the memory is
6412 zeroed (or filled with another predictable value), as is the case for
6413 calloc().
6414
6415 VALGRIND_MALLOCLIKE_BLOCK should be put immediately after the point where a
6416 heap block -- that will be used by the client program -- is allocated.
6417 It's best to put it at the outermost level of the allocator if possible;
6418 for example, if you have a function my_alloc() which calls
6419 internal_alloc(), and the client request is put inside internal_alloc(),
6420 stack traces relating to the heap block will contain entries for both
6421 my_alloc() and internal_alloc(), which is probably not what you want.
6422
6423 For Memcheck users: if you use VALGRIND_MALLOCLIKE_BLOCK to carve out
6424 custom blocks from within a heap block, B, that has been allocated with
6425 malloc/calloc/new/etc, then block B will be *ignored* during leak-checking
6426 -- the custom blocks will take precedence.
6427
6428 VALGRIND_FREELIKE_BLOCK is the partner to VALGRIND_MALLOCLIKE_BLOCK. For
6429 Memcheck, it does two things:
6430
6431 - It records that the block has been deallocated. This assumes that the
6432 block was annotated as having been allocated via
6433 VALGRIND_MALLOCLIKE_BLOCK. Otherwise, an error will be issued.
6434
6435 - It marks the block as being unaddressable.
6436
6437 VALGRIND_FREELIKE_BLOCK should be put immediately after the point where a
6438 heap block is deallocated.
6439
6440 VALGRIND_RESIZEINPLACE_BLOCK informs a tool about reallocation. For
6441 Memcheck, it does four things:
6442
6443 - It records that the size of a block has been changed. This assumes that
6444 the block was annotated as having been allocated via
6445 VALGRIND_MALLOCLIKE_BLOCK. Otherwise, an error will be issued.
6446
6447 - If the block shrunk, it marks the freed memory as being unaddressable.
6448
6449 - If the block grew, it marks the new area as undefined and defines a red
6450 zone past the end of the new block.
6451
6452 - The V-bits of the overlap between the old and the new block are preserved.
6453
6454 VALGRIND_RESIZEINPLACE_BLOCK should be put after allocation of the new block
6455 and before deallocation of the old block.
6456
6457 In many cases, these three client requests will not be enough to get your
6458 allocator working well with Memcheck. More specifically, if your allocator
6459 writes to freed blocks in any way then a VALGRIND_MAKE_MEM_UNDEFINED call
6460 will be necessary to mark the memory as addressable just before the zeroing
6461 occurs, otherwise you'll get a lot of invalid write errors. For example,
6462 you'll need to do this if your allocator recycles freed blocks, but it
6463 zeroes them before handing them back out (via VALGRIND_MALLOCLIKE_BLOCK).
6464 Alternatively, if your allocator reuses freed blocks for allocator-internal
6465 data structures, VALGRIND_MAKE_MEM_UNDEFINED calls will also be necessary.
6466
6467 Really, what's happening is a blurring of the lines between the client
6468 program and the allocator... after VALGRIND_FREELIKE_BLOCK is called, the
6469 memory should be considered unaddressable to the client program, but the
6470 allocator knows more than the rest of the client program and so may be able
6471 to safely access it. Extra client requests are necessary for Valgrind to
6472 understand the distinction between the allocator and the rest of the
6473 program.

6500 /* Create a memory pool with some flags specifying extended behaviour.
6501 When flags is zero, the behaviour is identical to VALGRIND_CREATE_MEMPOOL.
6502
6503 The flag VALGRIND_MEMPOOL_METAPOOL specifies that the pieces of memory
6504 associated with the pool using VALGRIND_MEMPOOL_ALLOC will be used
6505 by the application as superblocks to dole out MALLOC_LIKE blocks using
6506 VALGRIND_MALLOCLIKE_BLOCK. In other words, a meta pool is a "2 levels"
6507 pool : first level is the blocks described by VALGRIND_MEMPOOL_ALLOC.
6508 The second level blocks are described using VALGRIND_MALLOCLIKE_BLOCK.
6509 Note that the association between the pool and the second level blocks
6510 is implicit : second level blocks will be located inside first level
6511 blocks. It is necessary to use the VALGRIND_MEMPOOL_METAPOOL flag
6512 for such 2 levels pools, as otherwise valgrind will detect overlapping
6513 memory blocks, and will abort execution (e.g. during leak search).
6514
6515 Such a meta pool can also be marked as an 'auto free' pool using the flag
6516 VALGRIND_MEMPOOL_AUTO_FREE, which must be OR-ed together with the
6517 VALGRIND_MEMPOOL_METAPOOL. For an 'auto free' pool, VALGRIND_MEMPOOL_FREE
6518 will automatically free the second level blocks that are contained
6519 inside the first level block freed with VALGRIND_MEMPOOL_FREE.
6520 In other words, calling VALGRIND_MEMPOOL_FREE will cause implicit calls
6521 to VALGRIND_FREELIKE_BLOCK for all the second level blocks included
6522 in the first level block.
6523 Note: it is an error to use the VALGRIND_MEMPOOL_AUTO_FREE flag
6524 without the VALGRIND_MEMPOOL_METAPOOL flag.
