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.

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. */ 1693 1694 #define CALL_FN_W_v(lval, orig) \ 1695 do { \ 1696 volatile OrigFn _orig = (orig);

This 6375 happens automatically for the standard allocator functions such as 6376 malloc(), calloc(), realloc(), memalign(), new, new[], free(), delete, 6377 delete[], etc. 6378 6379 But if your program uses a custom allocator, this doesn't automatically 6380 happen, and Valgrind will not do as well. For example, if you allocate 6381 superblocks with mmap() and then allocates chunks of the superblocks, all 6382 Valgrind's observations will be at the mmap() level and it won't know that 6383 the chunks should be considered separate entities. In Memcheck's case, 6384 that means you probably won't get heap block overrun detection (because 6385 there won't be redzones marked as unaddressable) and you definitely won't 6386 get any leak detection. 6387 6388 The following client requests allow a custom allocator to be annotated so 6389 that it can be handled accurately by Valgrind. 6390 6391 VALGRIND_MALLOCLIKE_BLOCK marks a region of memory as having been allocated 6392 by a malloc()-like function. For Memcheck (an illustrative case), this 6393 does two things: 6394 6395 - It records that the block has been allocated. This means any addresses 6396 within the block mentioned in error messages will be 6397 identified as belonging to the block. It also means that if the block 6398 isn't freed it will be detected by the leak checker. 6399 6400 - It marks the block as being addressable and undefined (if 'is_zeroed' is 6401 not set), or addressable and defined (if 'is_zeroed' is set). This 6402 controls how accesses to the block by the program are handled. 6403 6404 'addr' is the start of the usable block (ie. after any 6405 redzone), 'sizeB' is its size. 'rzB' is the redzone size if the allocator 6406 can apply redzones -- these are blocks of padding at the start and end of 6407 each block. Adding redzones is recommended as it makes it much more likely 6408 Valgrind will spot block overruns. `is_zeroed' indicates if the memory is 6409 zeroed (or filled with another predictable value), as is the case for 6410 calloc(). 6411 6412 VALGRIND_MALLOCLIKE_BLOCK should be put immediately after the point where a 6413 heap block -- that will be used by the client program -- is allocated. 6414 It's best to put it at the outermost level of the allocator if possible; 6415 for example, if you have a function my_alloc() which calls 6416 internal_alloc(), and the client request is put inside internal_alloc(), 6417 stack traces relating to the heap block will contain entries for both 6418 my_alloc() and internal_alloc(), which is probably not what you want. 6419 6420 For Memcheck users: if you use VALGRIND_MALLOCLIKE_BLOCK to carve out 6421 custom blocks from within a heap block, B, that has been allocated with 6422 malloc/calloc/new/etc, then block B will be *ignored* during leak-checking 6423 -- the custom blocks will take precedence. 6424 6425 VALGRIND_FREELIKE_BLOCK is the partner to VALGRIND_MALLOCLIKE_BLOCK. For 6426 Memcheck, it does two things: 6427 6428 - It records that the block has been deallocated. This assumes that the 6429 block was annotated as having been allocated via 6430 VALGRIND_MALLOCLIKE_BLOCK. Otherwise, an error will be issued. 6431 6432 - It marks the block as being unaddressable. 6433 6434 VALGRIND_FREELIKE_BLOCK should be put immediately after the point where a 6435 heap block is deallocated. 6436 6437 VALGRIND_RESIZEINPLACE_BLOCK informs a tool about reallocation. For 6438 Memcheck, it does four things: 6439 6440 - It records that the size of a block has been changed. This assumes that 6441 the block was annotated as having been allocated via 6442 VALGRIND_MALLOCLIKE_BLOCK. Otherwise, an error will be issued. 6443 6444 - If the block shrunk, it marks the freed memory as being unaddressable. 6445 6446 - If the block grew, it marks the new area as undefined and defines a red 6447 zone past the end of the new block. 6448 6449 - The V-bits of the overlap between the old and the new block are preserved. 6450 6451 VALGRIND_RESIZEINPLACE_BLOCK should be put after allocation of the new block 6452 and before deallocation of the old block. 6453 6454 In many cases, these three client requests will not be enough to get your 6455 allocator working well with Memcheck. More specifically, if your allocator 6456 writes to freed blocks in any way then a VALGRIND_MAKE_MEM_UNDEFINED call 6457 will be necessary to mark the memory as addressable just before the zeroing 6458 occurs, otherwise you'll get a lot of invalid write errors. For example, 6459 you'll need to do this if your allocator recycles freed blocks, but it 6460 zeroes them before handing them back out (via VALGRIND_MALLOCLIKE_BLOCK). 6461 Alternatively, if your allocator reuses freed blocks for allocator-internal 6462 data structures, VALGRIND_MAKE_MEM_UNDEFINED calls will also be necessary. 6463 6464 Really, what's happening is a blurring of the lines between the client 6465 program and the allocator... after VALGRIND_FREELIKE_BLOCK is called, the 6466 memory should be considered unaddressable to the client program, but the 6467 allocator knows more than the rest of the client program and so may be able 6468 to safely access it. Extra client requests are necessary for Valgrind to 6469 understand the distinction between the allocator and the rest of the 6470 program. 6471 6472 Ignored if addr == 0. 6473 */ 6474 #define VALGRIND_MALLOCLIKE_BLOCK(addr, sizeB, rzB, is_zeroed) \ 6475 VALGRIND_DO_CLIENT_REQUEST_STMT(VG_USERREQ__MALLOCLIKE_BLOCK, \ 6476 addr, sizeB, rzB, is_zeroed, 0) 6477 6478 /* See the comment for VALGRIND_MALLOCLIKE_BLOCK for details. 6479 Ignored if addr == 0. 6480 */ 6481 #define VALGRIND_RESIZEINPLACE_BLOCK(addr, oldSizeB, newSizeB, rzB) \ 6482 VALGRIND_DO_CLIENT_REQUEST_STMT(VG_USERREQ__RESIZEINPLACE_BLOCK, \ 6483 addr, oldSizeB, newSizeB, rzB, 0) 6484 6485 /* See the comment for VALGRIND_MALLOCLIKE_BLOCK for details. 6486 Ignored if addr == 0. 6487 */ 6488 #define VALGRIND_FREELIKE_BLOCK(addr, rzB) \ 6489 VALGRIND_DO_CLIENT_REQUEST_STMT(VG_USERREQ__FREELIKE_BLOCK, \ 6490 addr, rzB, 0, 0, 0) 6491 6492 /* Create a memory pool. */ 6493 #define VALGRIND_CREATE_MEMPOOL(pool, rzB, is_zeroed) \ 6494 VALGRIND_DO_CLIENT_REQUEST_STMT(VG_USERREQ__CREATE_MEMPOOL, \ 6495 pool, rzB, is_zeroed, 0, 0) 6496 6497 /* Create a memory pool with some flags specifying extended behaviour. 6498 When flags is zero, the behaviour is identical to VALGRIND_CREATE_MEMPOOL. 6499 6500 The flag VALGRIND_MEMPOOL_METAPOOL specifies that the pieces of memory 6501 associated with the pool using VALGRIND_MEMPOOL_ALLOC will be used 6502 by the application as superblocks to dole out MALLOC_LIKE blocks using 6503 VALGRIND_MALLOCLIKE_BLOCK. In other words, a meta pool is a "2 levels" 6504 pool : first level is the blocks described by VALGRIND_MEMPOOL_ALLOC. 6505 The second level blocks are described using VALGRIND_MALLOCLIKE_BLOCK. 6506 Note that the association between the pool and the second level blocks 6507 is implicit : second level blocks will be located inside first level 6508 blocks.
