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. */

132 _zzq_rlval, _zzq_default, _zzq_request, \
133 _zzq_arg1, _zzq_arg2, _zzq_arg3, _zzq_arg4, _zzq_arg5) \

140/* The following defines the magic code sequences which the JITter
141 spots and handles magically. Don't look too closely at them as
142 they will rot your brain.
143
144 The assembly code sequences for all architectures is in this one
145 file. This is because this file must be stand-alone, and we don't
146 want to have multiple files.
147
148 For VALGRIND_DO_CLIENT_REQUEST, we must ensure that the default
149 value gets put in the return slot, so that everything works when
150 this is executed not under Valgrind. Args are passed in a memory
151 block, and so there's no intrinsic limit to the number that could
152 be passed, but it's currently five.
153
154 The macro args are:
155 _zzq_rlval result lvalue
156 _zzq_default default value (result returned when running on real CPU)
157 _zzq_request request code
158 _zzq_arg1..5 request params
159
160 The other two macros are used to support function wrapping, and are
161 a lot simpler. VALGRIND_GET_NR_CONTEXT returns the value of the
162 guest's NRADDR pseudo-register and whatever other information is
163 needed to safely run the call original from the wrapper: on
164 ppc64-linux, the R2 value at the divert point is also needed. This
165 information is abstracted into a user-visible type, OrigFn.
166
167 VALGRIND_CALL_NOREDIR_* behaves the same as the following on the
168 guest, but guarantees that the branch instruction will not be
169 redirected: x86: call *%eax, amd64: call *%rax, ppc32/ppc64:
170 branch-and-link-to-r11. VALGRIND_CALL_NOREDIR is just text, not a
171 complete inline asm, since it needs to be combined with more magic
172 inline asm stuff to be useful.

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

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

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

1025/* NB 9 Sept 07. There is a nasty kludge here in all these CALL_FN_
1026 macros. In order not to trash the stack redzone, we need to drop
1027 %rsp by 128 before the hidden call, and restore afterwards. The
1028 nastyness is that it is only by luck that the stack still appears
1029 to be unwindable during the hidden call - since then the behaviour
1030 of any routine using this macro does not match what the CFI data
1031 says. Sigh.
1032
1033 Why is this important? Imagine that a wrapper has a stack
1034 allocated local, and passes to the hidden call, a pointer to it.
1035 Because gcc does not know about the hidden call, it may allocate
1036 that local in the redzone. Unfortunately the hidden call may then
1037 trash it before it comes to use it. So we must step clear of the
1038 redzone, for the duration of the hidden call, to make it safe.
1039
1040 Probably the same problem afflicts the other redzone-style ABIs too
1041 (ppc64-linux, ppc32-aix5, ppc64-aix5); but for those, the stack is
1042 self describing (none of this CFI nonsense) so at least messing
1043 with the stack pointer doesn't give a danger of non-unwindable
1044 stack. */

3720 if you call a function with them that subsequently calls printf(),

3722 these working are made higher if the called function does not refer to
3723 any global variables, and does not refer to any libc or other functions
3724 (printf et al). Any kind of entanglement with libc or dynamic linking is
3725 likely to have a bad outcome, for tricky reasons which we've grappled

3785 use '0' if not. Adding redzones makes it more likely Valgrind will spot
3786 block overruns. `is_zeroed' indicates if the memory is zeroed, as it is
3787 for calloc(). Put it immediately after the point where a block is
3788 allocated.
3789
3790 If you're using Memcheck: If you're allocating memory via superblocks,
3791 and then handing out small chunks of each superblock, if you don't have
3792 redzones on your small blocks, it's worth marking the superblock with
3793 VALGRIND_MAKE_MEM_NOACCESS when it's created, so that block overruns are
3794 detected. But if you can put redzones on, it's probably better to not do
3795 this, so that messages for small overruns are described in terms of the
3796 small block rather than the superblock (but if you have a big overrun
3797 that skips over a redzone, you could miss an error this way). See
3798 memcheck/tests/custom_alloc.c for an example.
3799
3800 WARNING: if your allocator uses malloc() or 'new' to allocate
3801 superblocks, rather than mmap() or brk(), this will not work properly --
3802 you'll likely get assertion failures during leak detection. This is
3803 because Valgrind doesn't like seeing overlapping heap blocks. Sorry.
