| 64 The resulting executables will still run without Valgrind, just a | |

| 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. */ | |

| 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. | |

| 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 | |

| 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. | |
