61 | You can use these macros to manipulate and query Valgrind's |

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. */ |

220 | they will rot your brain. |
221 | |
222 | The assembly code sequences for all architectures is in this one |
223 | file. This is because this file must be stand-alone, and we don't |
224 | want to have multiple files. |
225 | |
226 | For VALGRIND_DO_CLIENT_REQUEST, we must ensure that the default |
227 | value gets put in the return slot, so that everything works when |
228 | this is executed not under Valgrind. Args are passed in a memory |
229 | block, and so there's no intrinsic limit to the number that could |
230 | be passed, but it's currently five. |
231 | |
232 | The macro args are: |
233 | _zzq_rlval result lvalue |
234 | _zzq_default default value (result returned when running on real CPU) |
235 | _zzq_request request code |
236 | _zzq_arg1..5 request params |
237 | |
238 | The other two macros are used to support function wrapping, and are |
239 | a lot simpler. VALGRIND_GET_NR_CONTEXT returns the value of the |
240 | guest's NRADDR pseudo-register and whatever other information is |
241 | needed to safely run the call original from the wrapper: on |
242 | ppc64-linux, the R2 value at the divert point is also needed. This |
243 | information is abstracted into a user-visible type, OrigFn. |
244 | |
245 | VALGRIND_CALL_NOREDIR_* behaves the same as the following on the |
246 | guest, but guarantees that the branch instruction will not be |
247 | redirected: x86: call *%eax, amd64: call *%rax, ppc32/ppc64: |
248 | branch-and-link-to-r11. VALGRIND_CALL_NOREDIR is just text, not a |
249 | complete inline asm, since it needs to be combined with more magic |
250 | inline asm stuff to be useful. |

1588 | /* This is all pretty complex. It's so as to make stack unwinding |
1589 | work reliably. See bug 243270. The basic problem is the sub and |
1590 | add of 128 of %rsp in all of the following macros. If gcc believes |
1591 | the CFA is in %rsp, then unwinding may fail, because what's at the |
1592 | CFA is not what gcc "expected" when it constructs the CFIs for the |
1593 | places where the macros are instantiated. |
1594 | |
1595 | But we can't just add a CFI annotation to increase the CFA offset |
1596 | by 128, to match the sub of 128 from %rsp, because we don't know |
1597 | whether gcc has chosen %rsp as the CFA at that point, or whether it |
1598 | has chosen some other register (eg, %rbp). In the latter case, |
1599 | adding a CFI annotation to change the CFA offset is simply wrong. |
1600 | |
1601 | So the solution is to get hold of the CFA using |
1602 | __builtin_dwarf_cfa(), put it in a known register, and add a |
1603 | CFI annotation to say what the register is. We choose %rbp for |
1604 | this (perhaps perversely), because: |
1605 | |
1606 | (1) %rbp is already subject to unwinding. If a new register was |
1607 | chosen then the unwinder would have to unwind it in all stack |
1608 | traces, which is expensive, and |
1609 | |
1610 | (2) %rbp is already subject to precise exception updates in the |
1611 | JIT. If a new register was chosen, we'd have to have precise |
1612 | exceptions for it too, which reduces performance of the |
1613 | generated code. |
1614 | |
1615 | However .. one extra complication. We can't just whack the result |
1616 | of __builtin_dwarf_cfa() into %rbp and then add %rbp to the |
1617 | list of trashed registers at the end of the inline assembly |
1618 | fragments; gcc won't allow %rbp to appear in that list. Hence |
1619 | instead we need to stash %rbp in %r15 for the duration of the asm, |
1620 | and say that %r15 is trashed instead. gcc seems happy to go with |
1621 | that. |
1622 | |
1623 | Oh .. and this all needs to be conditionalised so that it is |
1624 | unchanged from before this commit, when compiled with older gccs |
1625 | that don't support __builtin_dwarf_cfa. Furthermore, since |
1626 | this header file is freestanding, it has to be independent of |
1627 | config.h, and so the following conditionalisation cannot depend on |
1628 | configure time checks. |
1629 | |
1630 | Although it's not clear from |
1631 | 'defined(__GNUC__) && defined(__GCC_HAVE_DWARF2_CFI_ASM)', |
1632 | this expression excludes Darwin. |
1633 | .cfi directives in Darwin assembly appear to be completely |
1634 | different and I haven't investigated how they work. |
1635 | |
1636 | For even more entertainment value, note we have to use the |
1637 | completely undocumented __builtin_dwarf_cfa(), which appears to |
1638 | really compute the CFA, whereas __builtin_frame_address(0) claims |
1639 | to but actually doesn't. See |

1673 | /* NB 9 Sept 07. There is a nasty kludge here in all these CALL_FN_ |
1674 | macros. In order not to trash the stack redzone, we need to drop |
1675 | %rsp by 128 before the hidden call, and restore afterwards. The |
1676 | nastyness is that it is only by luck that the stack still appears |
1677 | to be unwindable during the hidden call - since then the behaviour |
1678 | of any routine using this macro does not match what the CFI data |
1679 | says. Sigh. |
1680 | |
1681 | Why is this important? Imagine that a wrapper has a stack |
1682 | allocated local, and passes to the hidden call, a pointer to it. |
1683 | Because gcc does not know about the hidden call, it may allocate |
1684 | that local in the redzone. Unfortunately the hidden call may then |
1685 | trash it before it comes to use it. So we must step clear of the |
1686 | redzone, for the duration of the hidden call, to make it safe. |
1687 | |
1688 | Probably the same problem afflicts the other redzone-style ABIs too |
1689 | (ppc64-linux); but for those, the stack is |
1690 | self describing (none of this CFI nonsense) so at least messing |
1691 | with the stack pointer doesn't give a danger of non-unwindable |
1692 | stack. */ |

6376 | /* Several Valgrind tools (Memcheck, Massif, Helgrind, DRD) rely on knowing |
6377 | when heap blocks are allocated in order to give accurate results. This |
6378 | happens automatically for the standard allocator functions such as |
6379 | malloc(), calloc(), realloc(), memalign(), new, new[], free(), delete, |
6380 | delete[], etc. |
6381 | |
6382 | But if your program uses a custom allocator, this doesn't automatically |
6383 | happen, and Valgrind will not do as well. For example, if you allocate |
6384 | superblocks with mmap() and then allocates chunks of the superblocks, all |
6385 | Valgrind's observations will be at the mmap() level and it won't know that |
6386 | the chunks should be considered separate entities. In Memcheck's case, |
6387 | that means you probably won't get heap block overrun detection (because |
6388 | there won't be redzones marked as unaddressable) and you definitely won't |
6389 | get any leak detection. |
6390 | |
6391 | The following client requests allow a custom allocator to be annotated so |
6392 | that it can be handled accurately by Valgrind. |
6393 | |
6394 | VALGRIND_MALLOCLIKE_BLOCK marks a region of memory as having been allocated |
6395 | by a malloc()-like function. For Memcheck (an illustrative case), this |
6396 | does two things: |
6397 | |
6398 | - It records that the block has been allocated. This means any addresses |
6399 | within the block mentioned in error messages will be |
6400 | identified as belonging to the block. It also means that if the block |
6401 | isn't freed it will be detected by the leak checker. |
6402 | |
6403 | - It marks the block as being addressable and undefined (if 'is_zeroed' is |
6404 | not set), or addressable and defined (if 'is_zeroed' is set). This |
6405 | controls how accesses to the block by the program are handled. |
6406 | |
6407 | 'addr' is the start of the usable block (ie. after any |
6408 | redzone), 'sizeB' is its size. 'rzB' is the redzone size if the allocator |
6409 | can apply redzones -- these are blocks of padding at the start and end of |
6410 | each block. Adding redzones is recommended as it makes it much more likely |
6411 | Valgrind will spot block overruns. `is_zeroed' indicates if the memory is |
6412 | zeroed (or filled with another predictable value), as is the case for |
6413 | calloc(). |
6414 | |
6415 | VALGRIND_MALLOCLIKE_BLOCK should be put immediately after the point where a |
6416 | heap block -- that will be used by the client program -- is allocated. |
6417 | It's best to put it at the outermost level of the allocator if possible; |
6418 | for example, if you have a function my_alloc() which calls |
6419 | internal_alloc(), and the client request is put inside internal_alloc(), |
6420 | stack traces relating to the heap block will contain entries for both |
6421 | my_alloc() and internal_alloc(), which is probably not what you want. |
6422 | |
6423 | For Memcheck users: if you use VALGRIND_MALLOCLIKE_BLOCK to carve out |
6424 | custom blocks from within a heap block, B, that has been allocated with |
6425 | malloc/calloc/new/etc, then block B will be *ignored* during leak-checking |
6426 | -- the custom blocks will take precedence. |
6427 | |
6428 | VALGRIND_FREELIKE_BLOCK is the partner to VALGRIND_MALLOCLIKE_BLOCK. For |
6429 | Memcheck, it does two things: |
6430 | |
6431 | - It records that the block has been deallocated. This assumes that the |
6432 | block was annotated as having been allocated via |
6433 | VALGRIND_MALLOCLIKE_BLOCK. Otherwise, an error will be issued. |
6434 | |
6435 | - It marks the block as being unaddressable. |
6436 | |
6437 | VALGRIND_FREELIKE_BLOCK should be put immediately after the point where a |
6438 | heap block is deallocated. |
6439 | |
6440 | VALGRIND_RESIZEINPLACE_BLOCK informs a tool about reallocation. For |
6441 | Memcheck, it does four things: |
6442 | |
6443 | - It records that the size of a block has been changed. This assumes that |
6444 | the block was annotated as having been allocated via |
6445 | VALGRIND_MALLOCLIKE_BLOCK. Otherwise, an error will be issued. |
6446 | |
6447 | - If the block shrunk, it marks the freed memory as being unaddressable. |
6448 | |
6449 | - If the block grew, it marks the new area as undefined and defines a red |
6450 | zone past the end of the new block. |
6451 | |
6452 | - The V-bits of the overlap between the old and the new block are preserved. |
6453 | |
6454 | VALGRIND_RESIZEINPLACE_BLOCK should be put after allocation of the new block |
6455 | and before deallocation of the old block. |
6456 | |
6457 | In many cases, these three client requests will not be enough to get your |
6458 | allocator working well with Memcheck. More specifically, if your allocator |
6459 | writes to freed blocks in any way then a VALGRIND_MAKE_MEM_UNDEFINED call |
6460 | will be necessary to mark the memory as addressable just before the zeroing |
6461 | occurs, otherwise you'll get a lot of invalid write errors. For example, |
6462 | you'll need to do this if your allocator recycles freed blocks, but it |
6463 | zeroes them before handing them back out (via VALGRIND_MALLOCLIKE_BLOCK). |
6464 | Alternatively, if your allocator reuses freed blocks for allocator-internal |
6465 | data structures, VALGRIND_MAKE_MEM_UNDEFINED calls will also be necessary. |
6466 | |
6467 | Really, what's happening is a blurring of the lines between the client |
6468 | program and the allocator... after VALGRIND_FREELIKE_BLOCK is called, the |
6469 | memory should be considered unaddressable to the client program, but the |
6470 | allocator knows more than the rest of the client program and so may be able |
6471 | to safely access it. Extra client requests are necessary for Valgrind to |
6472 | understand the distinction between the allocator and the rest of the |
6473 | program. |

6501 | When flags is zero, the behaviour is identical to VALGRIND_CREATE_MEMPOOL. |

6503 | The flag VALGRIND_MEMPOOL_METAPOOL specifies that the pieces of memory |
6504 | associated with the pool using VALGRIND_MEMPOOL_ALLOC will be used |
6505 | by the application as superblocks to dole out MALLOC_LIKE blocks using |
6506 | VALGRIND_MALLOCLIKE_BLOCK. In other words, a meta pool is a "2 levels" |
6507 | pool : first level is the blocks described by VALGRIND_MEMPOOL_ALLOC. |
6508 | The second level blocks are described using VALGRIND_MALLOCLIKE_BLOCK. |
6509 | Note that the association between the pool and the second level blocks |
6510 | is implicit : second level blocks will be located inside first level |
6511 | blocks. It is necessary to use the VALGRIND_MEMPOOL_METAPOOL flag |
6512 | for such 2 levels pools, as otherwise valgrind will detect overlapping |
6513 | memory blocks, and will abort execution (e.g. during leak search). |
6514 | |
6515 | Such a meta pool can also be marked as an 'auto free' pool using the flag |
6516 | VALGRIND_MEMPOOL_AUTO_FREE, which must be OR-ed together with the |
6517 | VALGRIND_MEMPOOL_METAPOOL. For an 'auto free' pool, VALGRIND_MEMPOOL_FREE |
6518 | will automatically free the second level blocks that are contained |
6519 | inside the first level block freed with VALGRIND_MEMPOOL_FREE. |
6520 | In other words, calling VALGRIND_MEMPOOL_FREE will cause implicit calls |
6521 | to VALGRIND_FREELIKE_BLOCK for all the second level blocks included |
6522 | in the first level block. |
6523 | Note: it is an error to use the VALGRIND_MEMPOOL_AUTO_FREE flag |
6524 | without the VALGRIND_MEMPOOL_METAPOOL flag. |
