You can use these macros to manipulate and query Valgrind's execution inside your own programs. The resulting executables will still run without Valgrind, just a little bit more slowly than they otherwise would, but otherwise unchanged. When not running on valgrind, each client request consumes very few (eg. 7) instructions, so the resulting performance loss is negligible unless you plan to execute client requests millions of times per second. Nevertheless, if that is still a problem, you can compile with the NVALGRIND symbol defined (gcc -DNVALGRIND) so that client requests are not even compiled in. */ #ifndef __VALGRIND_H #define __VALGRIND_H #include /* Nb: this file might be included in a file compiled with -ansi.

The assembly code sequences for all architectures is in this one file. This is because this file must be stand-alone, and we don't want to have multiple files. For VALGRIND_DO_CLIENT_REQUEST, we must ensure that the default value gets put in the return slot, so that everything works when this is executed not under Valgrind. Args are passed in a memory block, and so there's no intrinsic limit to the number that could be passed, but it's currently five. The macro args are: _zzq_rlval result lvalue _zzq_default default value (result returned when running on real CPU) _zzq_request request code _zzq_arg1..5 request params The other two macros are used to support function wrapping, and are a lot simpler. VALGRIND_GET_NR_CONTEXT returns the value of the guest's NRADDR pseudo-register and whatever other information is needed to safely run the call original from the wrapper: on ppc64-linux, the R2 value at the divert point is also needed. This information is abstracted into a user-visible type, OrigFn. VALGRIND_CALL_NOREDIR_* behaves the same as the following on the guest, but guarantees that the branch instruction will not be redirected: x86: call *%eax, amd64: call *%rax, ppc32/ppc64: branch-and-link-to-r11. VALGRIND_CALL_NOREDIR is just text, not a complete inline asm, since it needs to be combined with more magic inline asm stuff to be useful. */ /* ------------------------- x86-linux ------------------------- */ #if defined(PLAT_x86_linux) typedef struct { unsigned int nraddr; /* where's the code?

There is a nasty kludge here in all these CALL_FN_ macros. In order not to trash the stack redzone, we need to drop %rsp by 128 before the hidden call, and restore afterwards. The nastyness is that it is only by luck that the stack still appears to be unwindable during the hidden call - since then the behaviour of any routine using this macro does not match what the CFI data says. Sigh. Why is this important? Imagine that a wrapper has a stack allocated local, and passes to the hidden call, a pointer to it. Because gcc does not know about the hidden call, it may allocate that local in the redzone. Unfortunately the hidden call may then trash it before it comes to use it. So we must step clear of the redzone, for the duration of the hidden call, to make it safe. Probably the same problem afflicts the other redzone-style ABIs too (ppc64-linux, ppc32-aix5, ppc64-aix5); but for those, the stack is self describing (none of this CFI nonsense) so at least messing with the stack pointer doesn't give a danger of non-unwindable stack. */ #define CALL_FN_W_v(lval, orig) \ do { \ volatile OrigFn _orig = (orig);

See memcheck/tests/custom_alloc.c for an example.
