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

977 /* This section defines magic (a.k.a appalling-hack) macros for doing
978 guaranteed-no-redirection macros, so as to get from function
979 wrappers to the functions they are wrapping. The whole point is to
980 construct standard call sequences, but to do the call itself with a
981 special no-redirect call pseudo-instruction that the JIT
982 understands and handles specially. This section is long and
983 repetitious, and I can't see a way to make it shorter.
984
985 The naming scheme is as follows:
986
987 CALL_FN_{W,v}_{v,W,WW,WWW,WWWW,5W,6W,7W,etc}
988
989 'W' stands for "word" and 'v' for "void". Hence there are
990 different macros for calling arity 0, 1, 2, 3, 4, etc, functions,
991 and for each, the possibility of returning a word-typed result, or
992 no result.
993 */
994
995 /* Use these to write the name of your wrapper. NOTE: duplicates
996 VG_WRAP_FUNCTION_Z{U,Z} in pub_tool_redir.h. NOTE also: inserts
997 the default behaviour equivalance class tag "0000" into the name.
998 See pub_tool_redir.h for details -- normally you don't need to

1505 /* This is all pretty complex. It's so as to make stack unwinding
1506 work reliably. See bug 243270. The basic problem is the sub and
1507 add of 128 of %rsp in all of the following macros. If gcc believes
1508 the CFA is in %rsp, then unwinding may fail, because what's at the
1509 CFA is not what gcc "expected" when it constructs the CFIs for the
1510 places where the macros are instantiated.
1511
1512 But we can't just add a CFI annotation to increase the CFA offset
1513 by 128, to match the sub of 128 from %rsp, because we don't know
1514 whether gcc has chosen %rsp as the CFA at that point, or whether it
1515 has chosen some other register (eg, %rbp). In the latter case,
1516 adding a CFI annotation to change the CFA offset is simply wrong.
1517
1518 So the solution is to get hold of the CFA using
1519 __builtin_dwarf_cfa(), put it in a known register, and add a
1520 CFI annotation to say what the register is. We choose %rbp for
1521 this (perhaps perversely), because:
1522
1523 (1) %rbp is already subject to unwinding. If a new register was
1524 chosen then the unwinder would have to unwind it in all stack
1525 traces, which is expensive, and
1526
1527 (2) %rbp is already subject to precise exception updates in the
1528 JIT. If a new register was chosen, we'd have to have precise
1529 exceptions for it too, which reduces performance of the
1530 generated code.
1531
1532 However .. one extra complication. We can't just whack the result
1533 of __builtin_dwarf_cfa() into %rbp and then add %rbp to the
1534 list of trashed registers at the end of the inline assembly
1535 fragments; gcc won't allow %rbp to appear in that list. Hence
1536 instead we need to stash %rbp in %r15 for the duration of the asm,
1537 and say that %r15 is trashed instead. gcc seems happy to go with
1538 that.
1539
1540 Oh .. and this all needs to be conditionalised so that it is
1541 unchanged from before this commit, when compiled with older gccs
1542 that don't support __builtin_dwarf_cfa. Furthermore, since
1543 this header file is freestanding, it has to be independent of
1544 config.h, and so the following conditionalisation cannot depend on
1545 configure time checks.
1546
1547 Although it's not clear from
1548 'defined(__GNUC__) && defined(__GCC_HAVE_DWARF2_CFI_ASM)',
1549 this expression excludes Darwin.
1550 .cfi directives in Darwin assembly appear to be completely
1551 different and I haven't investigated how they work.
1552
1553 For even more entertainment value, note we have to use the
1554 completely undocumented __builtin_dwarf_cfa(), which appears to
1555 really compute the CFA, whereas __builtin_frame_address(0) claims
1556 to but actually doesn't. See
1557 https://bugs.kde.org/show_bug.cgi?id=243270#c47

1591 macros. In order not to trash the stack redzone, we need to drop
1592 %rsp by 128 before the hidden call, and restore afterwards. The
1593 nastyness is that it is only by luck that the stack still appears
1594 to be unwindable during the hidden call - since then the behaviour
1595 of any routine using this macro does not match what the CFI data
1596 says. Sigh.
1597
1598 Why is this important? Imagine that a wrapper has a stack
1599 allocated local, and passes to the hidden call, a pointer to it.
1600 Because gcc does not know about the hidden call, it may allocate
1601 that local in the redzone. Unfortunately the hidden call may then
1602 trash it before it comes to use it. So we must step clear of the
1603 redzone, for the duration of the hidden call, to make it safe.
1604
1605 Probably the same problem afflicts the other redzone-style ABIs too
1606 (ppc64-linux); but for those, the stack is
1607 self describing (none of this CFI nonsense) so at least messing
1608 with the stack pointer doesn't give a danger of non-unwindable
1609 stack. */

5725 happens automatically for the standard allocator functions such as
5726 malloc(), calloc(), realloc(), memalign(), new, new[], free(), delete,
5727 delete[], etc.
5728
5729 But if your program uses a custom allocator, this doesn't automatically
5730 happen, and Valgrind will not do as well. For example, if you allocate
5731 superblocks with mmap() and then allocates chunks of the superblocks, all
5732 Valgrind's observations will be at the mmap() level and it won't know that
5733 the chunks should be considered separate entities. In Memcheck's case,
5734 that means you probably won't get heap block overrun detection (because
5735 there won't be redzones marked as unaddressable) and you definitely won't
5736 get any leak detection.

5739 that it can be handled accurately by Valgrind.

5742 by a malloc()-like function. For Memcheck (an illustrative case), this
5743 does two things:
5744
5745 - It records that the block has been allocated. This means any addresses
5746 within the block mentioned in error messages will be
5747 identified as belonging to the block. It also means that if the block
5748 isn't freed it will be detected by the leak checker.
5749
5750 - It marks the block as being addressable and undefined (if 'is_zeroed' is
5751 not set), or addressable and defined (if 'is_zeroed' is set). This
5752 controls how accesses to the block by the program are handled.
5753
5754 'addr' is the start of the usable block (ie. after any
5755 redzone), 'sizeB' is its size. 'rzB' is the redzone size if the allocator
5756 can apply redzones -- these are blocks of padding at the start and end of
5757 each block. Adding redzones is recommended as it makes it much more likely
5758 Valgrind will spot block overruns. `is_zeroed' indicates if the memory is
5759 zeroed (or filled with another predictable value), as is the case for
5760 calloc().
5761
5762 VALGRIND_MALLOCLIKE_BLOCK should be put immediately after the point where a
5763 heap block -- that will be used by the client program -- is allocated.
5764 It's best to put it at the outermost level of the allocator if possible;
5765 for example, if you have a function my_alloc() which calls
5766 internal_alloc(), and the client request is put inside internal_alloc(),
5767 stack traces relating to the heap block will contain entries for both
5768 my_alloc() and internal_alloc(), which is probably not what you want.
5769
5770 For Memcheck users: if you use VALGRIND_MALLOCLIKE_BLOCK to carve out
5771 custom blocks from within a heap block, B, that has been allocated with
5772 malloc/calloc/new/etc, then block B will be *ignored* during leak-checking
5773 -- the custom blocks will take precedence.
5774
5775 VALGRIND_FREELIKE_BLOCK is the partner to VALGRIND_MALLOCLIKE_BLOCK. For
5776 Memcheck, it does two things:
5777
5778 - It records that the block has been deallocated. This assumes that the
5779 block was annotated as having been allocated via
5780 VALGRIND_MALLOCLIKE_BLOCK. Otherwise, an error will be issued.
5781
5782 - It marks the block as being unaddressable.
5783
5784 VALGRIND_FREELIKE_BLOCK should be put immediately after the point where a
5785 heap block is deallocated.
5786
5787 VALGRIND_RESIZEINPLACE_BLOCK informs a tool about reallocation. For
5788 Memcheck, it does four things:
5789
5790 - It records that the size of a block has been changed. This assumes that
5791 the block was annotated as having been allocated via
5792 VALGRIND_MALLOCLIKE_BLOCK. Otherwise, an error will be issued.
5793
5794 - If the block shrunk, it marks the freed memory as being unaddressable.
5795
5796 - If the block grew, it marks the new area as undefined and defines a red
5797 zone past the end of the new block.
5798
5799 - The V-bits of the overlap between the old and the new block are preserved.
5800
5801 VALGRIND_RESIZEINPLACE_BLOCK should be put after allocation of the new block
5802 and before deallocation of the old block.
5803
5804 In many cases, these three client requests will not be enough to get your
5805 allocator working well with Memcheck. More specifically, if your allocator
5806 writes to freed blocks in any way then a VALGRIND_MAKE_MEM_UNDEFINED call
5807 will be necessary to mark the memory as addressable just before the zeroing
5808 occurs, otherwise you'll get a lot of invalid write errors. For example,
5809 you'll need to do this if your allocator recycles freed blocks, but it
5810 zeroes them before handing them back out (via VALGRIND_MALLOCLIKE_BLOCK).
5811 Alternatively, if your allocator reuses freed blocks for allocator-internal
5812 data structures, VALGRIND_MAKE_MEM_UNDEFINED calls will also be necessary.
5813
5814 Really, what's happening is a blurring of the lines between the client
5815 program and the allocator... after VALGRIND_FREELIKE_BLOCK is called, the
5816 memory should be considered unaddressable to the client program, but the
5817 allocator knows more than the rest of the client program and so may be able
5818 to safely access it. Extra client requests are necessary for Valgrind to
5819 understand the distinction between the allocator and the rest of the
5820 program.
