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. */

170 /* The following defines the magic code sequences which the JITter
171 spots and handles magically. Don't look too closely at them as
172 they will rot your brain.
173
174 The assembly code sequences for all architectures is in this one
175 file. This is because this file must be stand-alone, and we don't
176 want to have multiple files.
177
178 For VALGRIND_DO_CLIENT_REQUEST, we must ensure that the default
179 value gets put in the return slot, so that everything works when
180 this is executed not under Valgrind. Args are passed in a memory
181 block, and so there's no intrinsic limit to the number that could
182 be passed, but it's currently five.
183
184 The macro args are:
185 _zzq_rlval result lvalue
186 _zzq_default default value (result returned when running on real CPU)
187 _zzq_request request code
188 _zzq_arg1..5 request params
189
190 The other two macros are used to support function wrapping, and are
191 a lot simpler. VALGRIND_GET_NR_CONTEXT returns the value of the
192 guest's NRADDR pseudo-register and whatever other information is
193 needed to safely run the call original from the wrapper: on
194 ppc64-linux, the R2 value at the divert point is also needed. This
195 information is abstracted into a user-visible type, OrigFn.
196
197 VALGRIND_CALL_NOREDIR_* behaves the same as the following on the
198 guest, but guarantees that the branch instruction will not be
199 redirected: x86: call *%eax, amd64: call *%rax, ppc32/ppc64:
200 branch-and-link-to-r11. VALGRIND_CALL_NOREDIR is just text, not a
201 complete inline asm, since it needs to be combined with more magic
202 inline asm stuff to be useful.

711 construct standard call sequences, but to do the call itself with a

1196 /* This is all pretty complex. It's so as to make stack unwinding
1197 work reliably. See bug 243270. The basic problem is the sub and
1198 add of 128 of %rsp in all of the following macros. If gcc believes
1199 the CFA is in %rsp, then unwinding may fail, because what's at the
1200 CFA is not what gcc "expected" when it constructs the CFIs for the
1201 places where the macros are instantiated.
1202
1203 But we can't just add a CFI annotation to increase the CFA offset
1204 by 128, to match the sub of 128 from %rsp, because we don't know
1205 whether gcc has chosen %rsp as the CFA at that point, or whether it
1206 has chosen some other register (eg, %rbp). In the latter case,
1207 adding a CFI annotation to change the CFA offset is simply wrong.
1208
1209 So the solution is to get hold of the CFA using
1210 __builtin_dwarf_cfa(), put it in a known register, and add a
1211 CFI annotation to say what the register is. We choose %rbp for
1212 this (perhaps perversely), because:
1213
1214 (1) %rbp is already subject to unwinding. If a new register was
1215 chosen then the unwinder would have to unwind it in all stack
1216 traces, which is expensive, and
1217
1218 (2) %rbp is already subject to precise exception updates in the
1219 JIT. If a new register was chosen, we'd have to have precise
1220 exceptions for it too, which reduces performance of the
1221 generated code.
1222
1223 However .. one extra complication. We can't just whack the result
1224 of __builtin_dwarf_cfa() into %rbp and then add %rbp to the
1225 list of trashed registers at the end of the inline assembly
1226 fragments; gcc won't allow %rbp to appear in that list. Hence
1227 instead we need to stash %rbp in %r15 for the duration of the asm,
1228 and say that %r15 is trashed instead. gcc seems happy to go with
1229 that.
1230
1231 Oh .. and this all needs to be conditionalised so that it is
1232 unchanged from before this commit, when compiled with older gccs
1233 that don't support __builtin_dwarf_cfa. Furthermore, since
1234 this header file is freestanding, it has to be independent of
1235 config.h, and so the following conditionalisation cannot depend on
1236 configure time checks.
1237
1238 Although it's not clear from
1239 'defined(__GNUC__) && defined(__GCC_HAVE_DWARF2_CFI_ASM)',
1240 this expression excludes Darwin.
1241 .cfi directives in Darwin assembly appear to be completely
1242 different and I haven't investigated how they work.
1243
1244 For even more entertainment value, note we have to use the
1245 completely undocumented __builtin_dwarf_cfa(), which appears to
1246 really compute the CFA, whereas __builtin_frame_address(0) claims
1247 to but actually doesn't. See
1248 https://bugs.kde.org/show_bug.cgi?id=243270#c47

1271 /* NB 9 Sept 07. There is a nasty kludge here in all these CALL_FN_
1272 macros. In order not to trash the stack redzone, we need to drop
1273 %rsp by 128 before the hidden call, and restore afterwards. The
1274 nastyness is that it is only by luck that the stack still appears
1275 to be unwindable during the hidden call - since then the behaviour
1276 of any routine using this macro does not match what the CFI data
1277 says. Sigh.
1278
1279 Why is this important? Imagine that a wrapper has a stack
1280 allocated local, and passes to the hidden call, a pointer to it.
1281 Because gcc does not know about the hidden call, it may allocate
1282 that local in the redzone. Unfortunately the hidden call may then
1283 trash it before it comes to use it. So we must step clear of the
1284 redzone, for the duration of the hidden call, to make it safe.
1285
1286 Probably the same problem afflicts the other redzone-style ABIs too
1287 (ppc64-linux, ppc32-aix5, ppc64-aix5); but for those, the stack is
1288 self describing (none of this CFI nonsense) so at least messing
1289 with the stack pointer doesn't give a danger of non-unwindable
1290 stack. */

4567 /* Several Valgrind tools (Memcheck, Massif, Helgrind, DRD) rely on knowing
4568 when heap blocks are allocated in order to give accurate results. This
4569 happens automatically for the standard allocator functions such as
4570 malloc(), calloc(), realloc(), memalign(), new, new[], free(), delete,
4571 delete[], etc.
4572
4573 But if your program uses a custom allocator, this doesn't automatically
4574 happen, and Valgrind will not do as well. For example, if you allocate
4575 superblocks with mmap() and then allocates chunks of the superblocks, all
4576 Valgrind's observations will be at the mmap() level and it won't know that
4577 the chunks should be considered separate entities. In Memcheck's case,
4578 that means you probably won't get heap block overrun detection (because
4579 there won't be redzones marked as unaddressable) and you definitely won't
4580 get any leak detection.
4581
4582 The following client requests allow a custom allocator to be annotated so
4583 that it can be handled accurately by Valgrind.
4584
4585 VALGRIND_MALLOCLIKE_BLOCK marks a region of memory as having been allocated
4586 by a malloc()-like function. For Memcheck (an illustrative case), this
4587 does two things:
4588
4589 - It records that the block has been allocated. This means any addresses
4590 within the block mentioned in error messages will be
4591 identified as belonging to the block. It also means that if the block
4592 isn't freed it will be detected by the leak checker.
4593
4594 - It marks the block as being addressable and undefined (if 'is_zeroed' is
4595 not set), or addressable and defined (if 'is_zeroed' is set). This
4596 controls how accesses to the block by the program are handled.
4597
4598 'addr' is the start of the usable block (ie. after any
4599 redzone), 'sizeB' is its size. 'rzB' is the redzone size if the allocator
4600 can apply redzones -- these are blocks of padding at the start and end of
4601 each block. Adding redzones is recommended as it makes it much more likely
4602 Valgrind will spot block overruns. `is_zeroed' indicates if the memory is
4603 zeroed (or filled with another predictable value), as is the case for
4604 calloc().
4605
4606 VALGRIND_MALLOCLIKE_BLOCK should be put immediately after the point where a
4607 heap block -- that will be used by the client program -- is allocated.
4608 It's best to put it at the outermost level of the allocator if possible;
4609 for example, if you have a function my_alloc() which calls
4610 internal_alloc(), and the client request is put inside internal_alloc(),
4611 stack traces relating to the heap block will contain entries for both
4612 my_alloc() and internal_alloc(), which is probably not what you want.
4613
4614 For Memcheck users: if you use VALGRIND_MALLOCLIKE_BLOCK to carve out
4615 custom blocks from within a heap block, B, that has been allocated with
4616 malloc/calloc/new/etc, then block B will be *ignored* during leak-checking
4617 -- the custom blocks will take precedence.
4618
4619 VALGRIND_FREELIKE_BLOCK is the partner to VALGRIND_MALLOCLIKE_BLOCK. For
4620 Memcheck, it does two things:
4621
4622 - It records that the block has been deallocated. This assumes that the
4623 block was annotated as having been allocated via
4624 VALGRIND_MALLOCLIKE_BLOCK. Otherwise, an error will be issued.
4625
4626 - It marks the block as being unaddressable.
4627
4628 VALGRIND_FREELIKE_BLOCK should be put immediately after the point where a
4629 heap block is deallocated.
4630
4631 In many cases, these two client requests will not be enough to get your
4632 allocator working well with Memcheck. More specifically, if your allocator
4633 writes to freed blocks in any way then a VALGRIND_MAKE_MEM_UNDEFINED call
4634 will be necessary to mark the memory as addressable just before the zeroing
4635 occurs, otherwise you'll get a lot of invalid write errors. For example,
4636 you'll need to do this if your allocator recycles freed blocks, but it
4637 zeroes them before handing them back out (via VALGRIND_MALLOCLIKE_BLOCK).
4638 Alternatively, if your allocator reuses freed blocks for allocator-internal
4639 data structures, VALGRIND_MAKE_MEM_UNDEFINED calls will also be necessary.
4640
4641 Really, what's happening is a blurring of the lines between the client
4642 program and the allocator... after VALGRIND_FREELIKE_BLOCK is called, the
4643 memory should be considered unaddressable to the client program, but the
4644 allocator knows more than the rest of the client program and so may be able
4645 to safely access it. Extra client requests are necessary for Valgrind to
4646 understand the distinction between the allocator and the rest of the
4647 program.
4648
4649 Note: there is currently no VALGRIND_REALLOCLIKE_BLOCK client request; it
4650 has to be emulated with MALLOCLIKE/FREELIKE and memory copying.
