12 You can use these macros to manipulate and query Valgrind's
13 execution inside your own programs.
14
15 The resulting executables will still run without Valgrind, just a
16 little bit more slowly than they otherwise would, but otherwise
17 unchanged. When not running on valgrind, each client request
18 consumes very few (eg. 7) instructions, so the resulting performance
19 loss is negligible unless you plan to execute client requests
20 millions of times per second. Nevertheless, if that is still a
21 problem, you can compile with the NVALGRIND symbol defined (gcc
22 -DNVALGRIND) so that client requests are not even compiled in. */

175 they will rot your brain.
176
177 The assembly code sequences for all architectures is in this one
178 file. This is because this file must be stand-alone, and we don't
179 want to have multiple files.
180
181 For VALGRIND_DO_CLIENT_REQUEST, we must ensure that the default
182 value gets put in the return slot, so that everything works when
183 this is executed not under Valgrind. Args are passed in a memory
184 block, and so there's no intrinsic limit to the number that could
185 be passed, but it's currently five.
186
187 The macro args are:
188 _zzq_rlval result lvalue
189 _zzq_default default value (result returned when running on real CPU)
190 _zzq_request request code
191 _zzq_arg1..5 request params
192
193 The other two macros are used to support function wrapping, and are
194 a lot simpler. VALGRIND_GET_NR_CONTEXT returns the value of the
195 guest's NRADDR pseudo-register and whatever other information is
196 needed to safely run the call original from the wrapper: on
197 ppc64-linux, the R2 value at the divert point is also needed. This
198 information is abstracted into a user-visible type, OrigFn.
199
200 VALGRIND_CALL_NOREDIR_* behaves the same as the following on the
201 guest, but guarantees that the branch instruction will not be
202 redirected: x86: call *%eax, amd64: call *%rax, ppc32/ppc64:
203 branch-and-link-to-r11. VALGRIND_CALL_NOREDIR is just text, not a
204 complete inline asm, since it needs to be combined with more magic
205 inline asm stuff to be useful.

1082/* This section defines magic (a.k.a appalling-hack) macros for doing
1083 guaranteed-no-redirection macros, so as to get from function
1084 wrappers to the functions they are wrapping. The whole point is to
1085 construct standard call sequences, but to do the call itself with a
1086 special no-redirect call pseudo-instruction that the JIT
1087 understands and handles specially. This section is long and
1088 repetitious, and I can't see a way to make it shorter.

1092 CALL_FN_{W,v}_{v,W,WW,WWW,WWWW,5W,6W,7W,etc}

1094 'W' stands for "word" and 'v' for "void". Hence there are
1095 different macros for calling arity 0, 1, 2, 3, 4, etc, functions,
1096 and for each, the possibility of returning a word-typed result, or
1097 no result.

1612/* This is all pretty complex. It's so as to make stack unwinding
1613 work reliably. See bug 243270. The basic problem is the sub and
1614 add of 128 of %rsp in all of the following macros. If gcc believes
1615 the CFA is in %rsp, then unwinding may fail, because what's at the
1616 CFA is not what gcc "expected" when it constructs the CFIs for the
1617 places where the macros are instantiated.
1618
1619 But we can't just add a CFI annotation to increase the CFA offset
1620 by 128, to match the sub of 128 from %rsp, because we don't know
1621 whether gcc has chosen %rsp as the CFA at that point, or whether it
1622 has chosen some other register (eg, %rbp). In the latter case,
1623 adding a CFI annotation to change the CFA offset is simply wrong.
1624
1625 So the solution is to get hold of the CFA using
1626 __builtin_dwarf_cfa(), put it in a known register, and add a
1627 CFI annotation to say what the register is. We choose %rbp for
1628 this (perhaps perversely), because:
1629
1630 (1) %rbp is already subject to unwinding. If a new register was
1631 chosen then the unwinder would have to unwind it in all stack
1632 traces, which is expensive, and
1633
1634 (2) %rbp is already subject to precise exception updates in the
1635 JIT. If a new register was chosen, we'd have to have precise
1636 exceptions for it too, which reduces performance of the
1637 generated code.
1638
1639 However .. one extra complication. We can't just whack the result
1640 of __builtin_dwarf_cfa() into %rbp and then add %rbp to the
1641 list of trashed registers at the end of the inline assembly
1642 fragments; gcc won't allow %rbp to appear in that list. Hence
1643 instead we need to stash %rbp in %r15 for the duration of the asm,
1644 and say that %r15 is trashed instead. gcc seems happy to go with
1645 that.
1646
1647 Oh .. and this all needs to be conditionalised so that it is
1648 unchanged from before this commit, when compiled with older gccs
1649 that don't support __builtin_dwarf_cfa. Furthermore, since
1650 this header file is freestanding, it has to be independent of
1651 config.h, and so the following conditionalisation cannot depend on
1652 configure time checks.
1653
1654 Although it's not clear from
1655 'defined(__GNUC__) && defined(__GCC_HAVE_DWARF2_CFI_ASM)',
1656 this expression excludes Darwin.
1657 .cfi directives in Darwin assembly appear to be completely
1658 different and I haven't investigated how they work.
1659
1660 For even more entertainment value, note we have to use the
1661 completely undocumented __builtin_dwarf_cfa(), which appears to
1662 really compute the CFA, whereas __builtin_frame_address(0) claims
1663 to but actually doesn't. See
1664 https://bugs.kde.org/show_bug.cgi?id=243270#c47

1697/* NB 9 Sept 07. There is a nasty kludge here in all these CALL_FN_
1698 macros. In order not to trash the stack redzone, we need to drop
1699 %rsp by 128 before the hidden call, and restore afterwards. The
1700 nastyness is that it is only by luck that the stack still appears
1701 to be unwindable during the hidden call - since then the behaviour
1702 of any routine using this macro does not match what the CFI data
1703 says. Sigh.
1704
1705 Why is this important? Imagine that a wrapper has a stack
1706 allocated local, and passes to the hidden call, a pointer to it.
1707 Because gcc does not know about the hidden call, it may allocate
1708 that local in the redzone. Unfortunately the hidden call may then
1709 trash it before it comes to use it. So we must step clear of the
1710 redzone, for the duration of the hidden call, to make it safe.
1711
1712 Probably the same problem afflicts the other redzone-style ABIs too
1713 (ppc64-linux); but for those, the stack is
1714 self describing (none of this CFI nonsense) so at least messing
1715 with the stack pointer doesn't give a danger of non-unwindable
1716 stack. */

6828/* Several Valgrind tools (Memcheck, Massif, Helgrind, DRD) rely on knowing
6829 when heap blocks are allocated in order to give accurate results. This
6830 happens automatically for the standard allocator functions such as
6831 malloc(), calloc(), realloc(), memalign(), new, new[], free(), delete,
6832 delete[], etc.
6833
6834 But if your program uses a custom allocator, this doesn't automatically
6835 happen, and Valgrind will not do as well. For example, if you allocate
6836 superblocks with mmap() and then allocates chunks of the superblocks, all
6837 Valgrind's observations will be at the mmap() level and it won't know that
6838 the chunks should be considered separate entities. In Memcheck's case,
6839 that means you probably won't get heap block overrun detection (because
6840 there won't be redzones marked as unaddressable) and you definitely won't
6841 get any leak detection.
6842
6843 The following client requests allow a custom allocator to be annotated so
6844 that it can be handled accurately by Valgrind.
6845
6846 VALGRIND_MALLOCLIKE_BLOCK marks a region of memory as having been allocated
6847 by a malloc()-like function. For Memcheck (an illustrative case), this
6848 does two things:
6849
6850 - It records that the block has been allocated. This means any addresses
6851 within the block mentioned in error messages will be
6852 identified as belonging to the block. It also means that if the block
6853 isn't freed it will be detected by the leak checker.
6854
6855 - It marks the block as being addressable and undefined (if 'is_zeroed' is
6856 not set), or addressable and defined (if 'is_zeroed' is set). This
6857 controls how accesses to the block by the program are handled.
6858
6859 'addr' is the start of the usable block (ie. after any
6860 redzone), 'sizeB' is its size. 'rzB' is the redzone size if the allocator
6861 can apply redzones -- these are blocks of padding at the start and end of
6862 each block. Adding redzones is recommended as it makes it much more likely
6863 Valgrind will spot block overruns. `is_zeroed' indicates if the memory is
6864 zeroed (or filled with another predictable value), as is the case for
6865 calloc().
6866
6867 VALGRIND_MALLOCLIKE_BLOCK should be put immediately after the point where a
6868 heap block -- that will be used by the client program -- is allocated.
6869 It's best to put it at the outermost level of the allocator if possible;
6870 for example, if you have a function my_alloc() which calls
6871 internal_alloc(), and the client request is put inside internal_alloc(),
6872 stack traces relating to the heap block will contain entries for both
6873 my_alloc() and internal_alloc(), which is probably not what you want.
6874
6875 For Memcheck users: if you use VALGRIND_MALLOCLIKE_BLOCK to carve out
6876 custom blocks from within a heap block, B, that has been allocated with
6877 malloc/calloc/new/etc, then block B will be *ignored* during leak-checking
6878 -- the custom blocks will take precedence.
6879
6880 VALGRIND_FREELIKE_BLOCK is the partner to VALGRIND_MALLOCLIKE_BLOCK. For
6881 Memcheck, it does two things:
6882
6883 - It records that the block has been deallocated. This assumes that the
6884 block was annotated as having been allocated via
6885 VALGRIND_MALLOCLIKE_BLOCK. Otherwise, an error will be issued.
6886
6887 - It marks the block as being unaddressable.
6888
6889 VALGRIND_FREELIKE_BLOCK should be put immediately after the point where a
6890 heap block is deallocated.
6891
6892 VALGRIND_RESIZEINPLACE_BLOCK informs a tool about reallocation. For
6893 Memcheck, it does four things:
6894
6895 - It records that the size of a block has been changed. This assumes that
6896 the block was annotated as having been allocated via
6897 VALGRIND_MALLOCLIKE_BLOCK. Otherwise, an error will be issued.
6898
6899 - If the block shrunk, it marks the freed memory as being unaddressable.
6900
6901 - If the block grew, it marks the new area as undefined and defines a red
6902 zone past the end of the new block.
6903
6904 - The V-bits of the overlap between the old and the new block are preserved.
6905
6906 VALGRIND_RESIZEINPLACE_BLOCK should be put after allocation of the new block
6907 and before deallocation of the old block.
6908
6909 In many cases, these three client requests will not be enough to get your
6910 allocator working well with Memcheck. More specifically, if your allocator
6911 writes to freed blocks in any way then a VALGRIND_MAKE_MEM_UNDEFINED call
6912 will be necessary to mark the memory as addressable just before the zeroing
6913 occurs, otherwise you'll get a lot of invalid write errors. For example,
6914 you'll need to do this if your allocator recycles freed blocks, but it
6915 zeroes them before handing them back out (via VALGRIND_MALLOCLIKE_BLOCK).
6916 Alternatively, if your allocator reuses freed blocks for allocator-internal
6917 data structures, VALGRIND_MAKE_MEM_UNDEFINED calls will also be necessary.
6918
6919 Really, what's happening is a blurring of the lines between the client
6920 program and the allocator... after VALGRIND_FREELIKE_BLOCK is called, the
6921 memory should be considered unaddressable to the client program, but the
6922 allocator knows more than the rest of the client program and so may be able
6923 to safely access it. Extra client requests are necessary for Valgrind to
6924 understand the distinction between the allocator and the rest of the
6925 program.

6953 When flags is zero, the behaviour is identical to VALGRIND_CREATE_MEMPOOL.
6954
6955 The flag VALGRIND_MEMPOOL_METAPOOL specifies that the pieces of memory
6956 associated with the pool using VALGRIND_MEMPOOL_ALLOC will be used
6957 by the application as superblocks to dole out MALLOC_LIKE blocks using
6958 VALGRIND_MALLOCLIKE_BLOCK. In other words, a meta pool is a "2 levels"
6959 pool : first level is the blocks described by VALGRIND_MEMPOOL_ALLOC.
6960 The second level blocks are described using VALGRIND_MALLOCLIKE_BLOCK.
6961 Note that the association between the pool and the second level blocks
6962 is implicit : second level blocks will be located inside first level
6963 blocks. It is necessary to use the VALGRIND_MEMPOOL_METAPOOL flag
6964 for such 2 levels pools, as otherwise valgrind will detect overlapping
6965 memory blocks, and will abort execution (e.g. during leak search).
6966
6967 Such a meta pool can also be marked as an 'auto free' pool using the flag
6968 VALGRIND_MEMPOOL_AUTO_FREE, which must be OR-ed together with the
6969 VALGRIND_MEMPOOL_METAPOOL. For an 'auto free' pool, VALGRIND_MEMPOOL_FREE
6970 will automatically free the second level blocks that are contained
6971 inside the first level block freed with VALGRIND_MEMPOOL_FREE.
6972 In other words, calling VALGRIND_MEMPOOL_FREE will cause implicit calls
6973 to VALGRIND_FREELIKE_BLOCK for all the second level blocks included
6974 in the first level block.
6975 Note: it is an error to use the VALGRIND_MEMPOOL_AUTO_FREE flag
6976 without the VALGRIND_MEMPOOL_METAPOOL flag.
