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

+/* 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

+ %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

+/* Several Valgrind tools (Memcheck, Massif, Helgrind, DRD) rely on knowing
+ when heap blocks are allocated in order to give accurate results. 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. Extra client requests are necessary for Valgrind to
+ understand the distinction between the allocator and the rest of the
+ program.
