+/* This is all pretty complex.  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.  See
+   https://bugs.kde.org/show_bug.cgi?id=243270#c47

+   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); but for those, the stack is
+   self describing (none of this CFI nonsense) so at least messing
+   with the stack pointer doesn't give a danger of non-unwindable

+   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.
-   If you're allocating memory via superblocks, and then handing out small
+   'addr' is the start of the usable block (ie. after any
-   chunks of each superblock, if you don't have redzones on your small
+   redzone), 'sizeB' is its size.  'rzB' is the redzone size if the allocator
-   blocks, it's worth marking the superblock with VALGRIND_MAKE_NOACCESS
+   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
-   when it's created, so that block overruns are detected.  But if you can
+   Valgrind will spot block overruns.  `is_zeroed' indicates if the memory is

+   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.
-   for small overruns are described in terms of the small block rather than
+   It's best to put it at the outermost level of the allocator if possible;
-   the superblock (but if you have a big overrun that skips over a redzone,

+   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

+   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).
