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

124 _zzq_rlval, _zzq_default, _zzq_request, \

135
136 The assembly code sequences for all architectures is in this one
137 file. This is because this file must be stand-alone, and we don't
138 want to have multiple files.
139
140 For VALGRIND_DO_CLIENT_REQUEST, we must ensure that the default
141 value gets put in the return slot, so that everything works when
142 this is executed not under Valgrind. Args are passed in a memory
143 block, and so there's no intrinsic limit to the number that could
144 be passed, but it's currently five.
145
146 The macro args are:
147 _zzq_rlval result lvalue
148 _zzq_default default value (result returned when running on real CPU)
149 _zzq_request request code
150 _zzq_arg1..5 request params
151
152 The other two macros are used to support function wrapping, and are
153 a lot simpler. VALGRIND_GET_NR_CONTEXT returns the value of the
154 guest's NRADDR pseudo-register and whatever other information is
155 needed to safely run the call original from the wrapper: on
156 ppc64-linux, the R2 value at the divert point is also needed. This
157 information is abstracted into a user-visible type, OrigFn.
158
159 VALGRIND_CALL_NOREDIR_* behaves the same as the following on the
160 guest, but guarantees that the branch instruction will not be
161 redirected: x86: call *%eax, amd64: call *%rax, ppc32/ppc64:
162 branch-and-link-to-r11. VALGRIND_CALL_NOREDIR is just text, not a
163 complete inline asm, since it needs to be combined with more magic
164 inline asm stuff to be useful.

2435 use '0' if not. Adding redzones makes it more likely Valgrind will spot
2436 block overruns. `is_zeroed' indicates if the memory is zeroed, as it is
2437 for calloc(). Put it immediately after the point where a block is
2438 allocated.
2439
2440 If you're allocating memory via superblocks, and then handing out small
2441 chunks of each superblock, if you don't have redzones on your small
2442 blocks, it's worth marking the superblock with VALGRIND_MAKE_MEM_NOACCESS
2443 when it's created, so that block overruns are detected. But if you can
2444 put redzones on, it's probably better to not do this, so that messages
2445 for small overruns are described in terms of the small block rather than
2446 the superblock (but if you have a big overrun that skips over a redzone,
2447 you could miss an error this way). See memcheck/tests/custom_alloc.c
2448 for an example.
2449
2450 WARNING: if your allocator uses malloc() or 'new' to allocate
2451 superblocks, rather than mmap() or brk(), this will not work properly --
2452 you'll likely get assertion failures during leak detection. This is
2453 because Valgrind doesn't like seeing overlapping heap blocks. Sorry.
