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. */

140 _zzq_rlval, _zzq_default, _zzq_request, \
141 _zzq_arg1, _zzq_arg2, _zzq_arg3, _zzq_arg4, _zzq_arg5) \

148 /* The following defines the magic code sequences which the JITter
149 spots and handles magically. Don't look too closely at them as
150 they will rot your brain.
151
152 The assembly code sequences for all architectures is in this one
153 file. This is because this file must be stand-alone, and we don't
154 want to have multiple files.
155
156 For VALGRIND_DO_CLIENT_REQUEST, we must ensure that the default
157 value gets put in the return slot, so that everything works when
158 this is executed not under Valgrind. Args are passed in a memory
159 block, and so there's no intrinsic limit to the number that could
160 be passed, but it's currently five.
161
162 The macro args are:
163 _zzq_rlval result lvalue
164 _zzq_default default value (result returned when running on real CPU)
165 _zzq_request request code
166 _zzq_arg1..5 request params
167
168 The other two macros are used to support function wrapping, and are
169 a lot simpler. VALGRIND_GET_NR_CONTEXT returns the value of the
170 guest's NRADDR pseudo-register and whatever other information is
171 needed to safely run the call original from the wrapper: on
172 ppc64-linux, the R2 value at the divert point is also needed. This
173 information is abstracted into a user-visible type, OrigFn.
174
175 VALGRIND_CALL_NOREDIR_* behaves the same as the following on the
176 guest, but guarantees that the branch instruction will not be
177 redirected: x86: call *%eax, amd64: call *%rax, ppc32/ppc64:
178 branch-and-link-to-r11. VALGRIND_CALL_NOREDIR is just text, not a
179 complete inline asm, since it needs to be combined with more magic
180 inline asm stuff to be useful.

631 guaranteed-no-redirection macros, so as to get from function
632 wrappers to the functions they are wrapping. The whole point is to
633 construct standard call sequences, but to do the call itself with a
634 special no-redirect call pseudo-instruction that the JIT
635 understands and handles specially. This section is long and
636 repetitious, and I can't see a way to make it shorter.

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

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

1112 /* NB 9 Sept 07. There is a nasty kludge here in all these CALL_FN_
1113 macros. In order not to trash the stack redzone, we need to drop
1114 %rsp by 128 before the hidden call, and restore afterwards. The
1115 nastyness is that it is only by luck that the stack still appears
1116 to be unwindable during the hidden call - since then the behaviour
1117 of any routine using this macro does not match what the CFI data
1118 says. Sigh.
1119
1120 Why is this important? Imagine that a wrapper has a stack
1121 allocated local, and passes to the hidden call, a pointer to it.
1122 Because gcc does not know about the hidden call, it may allocate
1123 that local in the redzone. Unfortunately the hidden call may then
1124 trash it before it comes to use it. So we must step clear of the
1125 redzone, for the duration of the hidden call, to make it safe.
1126
1127 Probably the same problem afflicts the other redzone-style ABIs too
1128 (ppc64-linux, ppc32-aix5, ppc64-aix5); but for those, the stack is
1129 self describing (none of this CFI nonsense) so at least messing
1130 with the stack pointer doesn't give a danger of non-unwindable
1131 stack. */

4304 /* Several Valgrind tools (Memcheck, Massif, Helgrind, DRD) rely on knowing
4305 when heap blocks are allocated in order to give accurate results. This
4306 happens automatically for the standard allocator functions such as
4307 malloc(), calloc(), realloc(), memalign(), new, new[], free(), delete,
4308 delete[], etc.
4309
4310 But if your program uses a custom allocator, this doesn't automatically
4311 happen, and Valgrind will not do as well. For example, if you allocate
4312 superblocks with mmap() and then allocates chunks of the superblocks, all
4313 Valgrind's observations will be at the mmap() level and it won't know that
4314 the chunks should be considered separate entities. In Memcheck's case,
4315 that means you probably won't get heap block overrun detection (because
4316 there won't be redzones marked as unaddressable) and you definitely won't
4317 get any leak detection.
4318
4319 The following client requests allow a custom allocator to be annotated so
4320 that it can be handled accurately by Valgrind.
4321
4322 VALGRIND_MALLOCLIKE_BLOCK marks a region of memory as having been allocated
4323 by a malloc()-like function. For Memcheck (an illustrative case), this
4324 does two things:
4325
4326 - It records that the block has been allocated. This means any addresses
4327 within the block mentioned in error messages will be
4328 identified as belonging to the block. It also means that if the block
4329 isn't freed it will be detected by the leak checker.
4330
4331 - It marks the block as being addressable and undefined (if 'is_zeroed' is
4332 not set), or addressable and defined (if 'is_zeroed' is set). This
4333 controls how accesses to the block by the program are handled.
4334
4335 'addr' is the start of the usable block (ie. after any
4336 redzone), 'sizeB' is its size. 'rzB' is the redzone size if the allocator
4337 can apply redzones -- these are blocks of padding at the start and end of
4338 each block. Adding redzones is recommended as it makes it much more likely
4339 Valgrind will spot block overruns. `is_zeroed' indicates if the memory is
4340 zeroed (or filled with another predictable value), as is the case for
4341 calloc().
4342
4343 VALGRIND_MALLOCLIKE_BLOCK should be put immediately after the point where a
4344 heap block -- that will be used by the client program -- is allocated.
4345 It's best to put it at the outermost level of the allocator if possible;
4346 for example, if you have a function my_alloc() which calls
4347 internal_alloc(), and the client request is put inside internal_alloc(),
4348 stack traces relating to the heap block will contain entries for both
4349 my_alloc() and internal_alloc(), which is probably not what you want.
4350
4351 For Memcheck users: if you use VALGRIND_MALLOCLIKE_BLOCK to carve out
4352 custom blocks from within a heap block, B, that has been allocated with
4353 malloc/calloc/new/etc, then block B will be *ignored* during leak-checking
4354 -- the custom blocks will take precedence.
4355
4356 VALGRIND_FREELIKE_BLOCK is the partner to VALGRIND_MALLOCLIKE_BLOCK. For
4357 Memcheck, it does two things:
4358
4359 - It records that the block has been deallocated. This assumes that the
4360 block was annotated as having been allocated via
4361 VALGRIND_MALLOCLIKE_BLOCK. Otherwise, an error will be issued.
4362
4363 - It marks the block as being unaddressable.
4364
4365 VALGRIND_FREELIKE_BLOCK should be put immediately after the point where a
4366 heap block is deallocated.
4367
4368 In many cases, these two client requests will not be enough to get your
4369 allocator working well with Memcheck. More specifically, if your allocator
4370 writes to freed blocks in any way then a VALGRIND_MAKE_MEM_UNDEFINED call
4371 will be necessary to mark the memory as addressable just before the zeroing
4372 occurs, otherwise you'll get a lot of invalid write errors. For example,
4373 you'll need to do this if your allocator recycles freed blocks, but it
4374 zeroes them before handing them back out (via VALGRIND_MALLOCLIKE_BLOCK).
4375 Alternatively, if your allocator reuses freed blocks for allocator-internal
4376 data structures, VALGRIND_MAKE_MEM_UNDEFINED calls will also be necessary.
4377
4378 Really, what's happening is a blurring of the lines between the client
4379 program and the allocator... after VALGRIND_FREELIKE_BLOCK is called, the
4380 memory should be considered unaddressable to the client program, but the
4381 allocator knows more than the rest of the client program and so may be able
4382 to safely access it. Extra client requests are necessary for Valgrind to
4383 understand the distinction between the allocator and the rest of the
4384 program.
4385
4386 Note: there is currently no VALGRIND_REALLOCLIKE_BLOCK client request; it
4387 has to be emulated with MALLOCLIKE/FREELIKE and memory copying.
