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.

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. + + VALGRIND_RESIZEINPLACE_BLOCK informs a tool about reallocation. For + Memcheck, it does four things: + + - It records that the size of a block has been changed. This assumes that + the block was annotated as having been allocated via + VALGRIND_MALLOCLIKE_BLOCK. Otherwise, an error will be issued. + + - If the block shrunk, it marks the freed memory as being unaddressable. + + - If the block grew, it marks the new area as undefined and defines a red + zone past the end of the new block. + + - The V-bits of the overlap between the old and the new block are preserved. + + VALGRIND_RESIZEINPLACE_BLOCK should be put after allocation of the new block + and before deallocation of the old block. + + In many cases, these three 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.
