/* This file is for inclusion into client (your!) code.

   You can use these macros to manipulate and query Valgrind's
   execution inside your own programs.

   The resulting executables will still run without Valgrind, just a
   little bit more slowly than they otherwise would, but otherwise
   unchanged.  When not running on valgrind, each client request
   consumes very few (eg. 7) instructions, so the resulting performance
   loss is negligible unless you plan to execute client requests
   millions of times per second.  Nevertheless, if that is still a
   problem, you can compile with the NVALGRIND symbol defined (gcc
   -DNVALGRIND) so that client requests are not even compiled in.  */

/* The following defines the magic code sequences which the JITter
   spots and handles magically.  Don't look too closely at them as
   they will rot your brain.

   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 section defines magic (a.k.a appalling-hack) macros for doing
   guaranteed-no-redirection macros, so as to get from function
   wrappers to the functions they are wrapping.  The whole point is to
   construct standard call sequences, but to do the call itself with a
   special no-redirect call pseudo-instruction that the JIT
   understands and handles specially.  This section is long and
   repetitious, and I can't see a way to make it shorter.

   The naming scheme is as follows:

      CALL_FN_{W,v}_{v,W,WW,WWW,WWWW,5W,6W,7W,etc}

   'W' stands for "word" and 'v' for "void".  Hence there are
   different macros for calling arity 0, 1, 2, 3, 4, etc, functions,
   and for each, the possibility of returning a word-typed result, or
   no result.

/* These CALL_FN_ macros assume that on amd64-linux, sizeof(unsigned
   long) == 8. */

/* NB 9 Sept 07.  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); 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
   stack. */

   these working are made higher if the called function does not refer to
   any global variables, and does not refer to any libc or other functions
   (printf et al).  Any kind of entanglement with libc or dynamic linking is
   likely to have a bad outcome, for tricky reasons which we've grappled

/* 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.

   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.
