It's so as to make stack unwinding - work reliably. See bug 243270. The basic problem is the sub and - add of 128 of %rsp in all of the following macros. If gcc believes - the CFA is in %rsp, then unwinding may fail, because what's at the - CFA is not what gcc "expected" when it constructs the CFIs for the - places where the macros are instantiated. - - But we can't just add a CFI annotation to increase the CFA offset - by 128, to match the sub of 128 from %rsp, because we don't know - whether gcc has chosen %rsp as the CFA at that point, or whether it - has chosen some other register (eg, %rbp). In the latter case, - adding a CFI annotation to change the CFA offset is simply wrong. - - So the solution is to get hold of the CFA using - __builtin_dwarf_cfa(), put it in a known register, and add a - CFI annotation to say what the register is. We choose %rbp for - this (perhaps perversely), because: - - (1) %rbp is already subject to unwinding. If a new register was - chosen then the unwinder would have to unwind it in all stack - traces, which is expensive, and - - (2) %rbp is already subject to precise exception updates in the - JIT. If a new register was chosen, we'd have to have precise - exceptions for it too, which reduces performance of the - generated code. - - However .. one extra complication. We can't just whack the result - of __builtin_dwarf_cfa() into %rbp and then add %rbp to the - list of trashed registers at the end of the inline assembly - fragments; gcc won't allow %rbp to appear in that list. Hence - instead we need to stash %rbp in %r15 for the duration of the asm, - and say that %r15 is trashed instead. gcc seems happy to go with - that. - - Oh .. and this all needs to be conditionalised so that it is - unchanged from before this commit, when compiled with older gccs - that don't support __builtin_dwarf_cfa. Furthermore, since - this header file is freestanding, it has to be independent of - config.h, and so the following conditionalisation cannot depend on - configure time checks. - - Although it's not clear from - 'defined(__GNUC__) && defined(__GCC_HAVE_DWARF2_CFI_ASM)', - this expression excludes Darwin. - .cfi directives in Darwin assembly appear to be completely - different and I haven't investigated how they work. - - For even more entertainment value, note we have to use the - completely undocumented __builtin_dwarf_cfa(), which appears to - really compute the CFA, whereas __builtin_frame_address(0) claims - to but actually doesn't.

There is a nasty kludge here in all these CALL_FN_ - macros. In order not to trash the stack redzone, we need to drop - %rsp by 128 before the hidden call, and restore afterwards. The - nastyness is that it is only by luck that the stack still appears - to be unwindable during the hidden call - since then the behaviour - of any routine using this macro does not match what the CFI data - says. Sigh. - - Why is this important? Imagine that a wrapper has a stack - allocated local, and passes to the hidden call, a pointer to it. - Because gcc does not know about the hidden call, it may allocate - that local in the redzone. Unfortunately the hidden call may then - trash it before it comes to use it. So we must step clear of the - redzone, for the duration of the hidden call, to make it safe. - - Probably the same problem afflicts the other redzone-style ABIs too - (ppc64-linux, ppc32-aix5, ppc64-aix5);

This - happens automatically for the standard allocator functions such as - malloc(), calloc(), realloc(), memalign(), new, new[], free(), delete, - delete[], etc. - - But if your program uses a custom allocator, this doesn't automatically - happen, and Valgrind will not do as well. For example, if you allocate - superblocks with mmap() and then allocates chunks of the superblocks, all - Valgrind's observations will be at the mmap() level and it won't know that - the chunks should be considered separate entities. In Memcheck's case, - that means you probably won't get heap block overrun detection (because - there won't be redzones marked as unaddressable) and you definitely won't - get any leak detection. - - The following client requests allow a custom allocator to be annotated so - that it can be handled accurately by Valgrind. - - VALGRIND_MALLOCLIKE_BLOCK marks a region of memory as having been allocated - by a malloc()-like function. For Memcheck (an illustrative case), this - does two things: - - - It records that the block has been allocated. This means any addresses - within the block mentioned in error messages will be - identified as belonging to the block. It also means that if the block - isn't freed it will be detected by the leak checker. - - - It marks the block as being addressable and undefined (if 'is_zeroed' is - not set), or addressable and defined (if 'is_zeroed' is set). This - controls how accesses to the block by the program are handled. - - 'addr' is the start of the usable block (ie. after any - redzone), 'sizeB' is its size. 'rzB' is the redzone size if the allocator - can apply redzones -- these are blocks of padding at the start and end of - each block. Adding redzones is recommended as it makes it much more likely - Valgrind will spot block overruns. `is_zeroed' indicates if the memory is - zeroed (or filled with another predictable value), as is the case for - calloc(). - - VALGRIND_MALLOCLIKE_BLOCK should be put immediately after the point where a - heap block -- that will be used by the client program -- is allocated. - It's best to put it at the outermost level of the allocator if possible; - for example, if you have a function my_alloc() which calls - internal_alloc(), and the client request is put inside internal_alloc(), - stack traces relating to the heap block will contain entries for both - my_alloc() and internal_alloc(), which is probably not what you want. - - For Memcheck users: if you use VALGRIND_MALLOCLIKE_BLOCK to carve out - custom blocks from within a heap block, B, that has been allocated with - malloc/calloc/new/etc, then block B will be *ignored* during leak-checking - -- the custom blocks will take precedence. - - VALGRIND_FREELIKE_BLOCK is the partner to VALGRIND_MALLOCLIKE_BLOCK. For - Memcheck, it does two things: - - - It records that the block has been deallocated. This assumes that the - block was annotated as having been allocated via - VALGRIND_MALLOCLIKE_BLOCK. Otherwise, an error will be issued. - - - It marks the block as being unaddressable. - - VALGRIND_FREELIKE_BLOCK should be put immediately after the point where a - heap block is deallocated. - - In many cases, these two client requests will not be enough to get your - allocator working well with Memcheck. More specifically, if your allocator - writes to freed blocks in any way then a VALGRIND_MAKE_MEM_UNDEFINED call - will be necessary to mark the memory as addressable just before the zeroing - occurs, otherwise you'll get a lot of invalid write errors. For example, - you'll need to do this if your allocator recycles freed blocks, but it - zeroes them before handing them back out (via VALGRIND_MALLOCLIKE_BLOCK). - Alternatively, if your allocator reuses freed blocks for allocator-internal - data structures, VALGRIND_MAKE_MEM_UNDEFINED calls will also be necessary. - - Really, what's happening is a blurring of the lines between the client - program and the allocator... after VALGRIND_FREELIKE_BLOCK is called, the - memory should be considered unaddressable to the client program, but the - allocator knows more than the rest of the client program and so may be able - to safely access it. Extra client requests are necessary for Valgrind to - understand the distinction between the allocator and the rest of the - program. - - Note: there is currently no VALGRIND_REALLOCLIKE_BLOCK client request; it - has to be emulated with MALLOCLIKE/FREELIKE and memory copying. - - Ignored if addr == 0. -*/ -#define VALGRIND_MALLOCLIKE_BLOCK(addr, sizeB, rzB, is_zeroed) \ - {unsigned int _qzz_res; \ - VALGRIND_DO_CLIENT_REQUEST(_qzz_res, 0, \ - VG_USERREQ__MALLOCLIKE_BLOCK, \ - addr, sizeB, rzB, is_zeroed, 0); \ - } - -/* See the comment for VALGRIND_MALLOCLIKE_BLOCK for details. - Ignored if addr == 0. -*/ -#define VALGRIND_FREELIKE_BLOCK(addr, rzB) \ - {unsigned int _qzz_res; \ - VALGRIND_DO_CLIENT_REQUEST(_qzz_res, 0, \ - VG_USERREQ__FREELIKE_BLOCK, \ - addr, rzB, 0, 0, 0); \ - } - -/* Create a memory pool. */ -#define VALGRIND_CREATE_MEMPOOL(pool, rzB, is_zeroed) \ - {unsigned int _qzz_res; \ - VALGRIND_DO_CLIENT_REQUEST(_qzz_res, 0, \ - VG_USERREQ__CREATE_MEMPOOL, \ - pool, rzB, is_zeroed, 0, 0); \ - } - -/* Destroy a memory pool. */ -#define VALGRIND_DESTROY_MEMPOOL(pool) \ - {unsigned int _qzz_res; \ - VALGRIND_DO_CLIENT_REQUEST(_qzz_res, 0, \ - VG_USERREQ__DESTROY_MEMPOOL, \ - pool, 0, 0, 0, 0); \ - } - -/* Associate a piece of memory with a memory pool. */ -#define VALGRIND_MEMPOOL_ALLOC(pool, addr, size) \ - {unsigned int _qzz_res; \ - VALGRIND_DO_CLIENT_REQUEST(_qzz_res, 0, \ - VG_USERREQ__MEMPOOL_ALLOC, \ - pool, addr, size, 0, 0); \ - } - -/* Disassociate a piece of memory from a memory pool. */ -#define VALGRIND_MEMPOOL_FREE(pool, addr) \ - {unsigned int _qzz_res; \ - VALGRIND_DO_CLIENT_REQUEST(_qzz_res, 0, \ - VG_USERREQ__MEMPOOL_FREE, \ - pool, addr, 0, 0, 0); \ - } - -/* Disassociate any pieces outside a particular range. */ -#define VALGRIND_MEMPOOL_TRIM(pool, addr, size) \ - {unsigned int _qzz_res; \ - VALGRIND_DO_CLIENT_REQUEST(_qzz_res, 0, \ - VG_USERREQ__MEMPOOL_TRIM, \ - pool, addr, size, 0, 0); \ - } - -/* Resize and/or move a piece associated with a memory pool. */ -#define VALGRIND_MOVE_MEMPOOL(poolA, poolB) \ - {unsigned int _qzz_res; \ - VALGRIND_DO_CLIENT_REQUEST(_qzz_res, 0, \ - VG_USERREQ__MOVE_MEMPOOL, \ - poolA, poolB, 0, 0, 0); \ - } - -/* Resize and/or move a piece associated with a memory pool. */ -#define VALGRIND_MEMPOOL_CHANGE(pool, addrA, addrB, size) \ - {unsigned int _qzz_res; \ - VALGRIND_DO_CLIENT_REQUEST(_qzz_res, 0, \ - VG_USERREQ__MEMPOOL_CHANGE, \ - pool, addrA, addrB, size, 0); \ - } - -/* Return 1 if a mempool exists, else 0. */ -#define VALGRIND_MEMPOOL_EXISTS(pool) \ - __extension__ \ - ({unsigned int _qzz_res; \ - VALGRIND_DO_CLIENT_REQUEST(_qzz_res, 0, \ - VG_USERREQ__MEMPOOL_EXISTS, \ - pool, 0, 0, 0, 0); \ - _qzz_res; \ - }) - -/* Mark a piece of memory as being a stack.
