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

132  _zzq_rlval, _zzq_default, _zzq_request, \
133  _zzq_arg1, _zzq_arg2, _zzq_arg3, _zzq_arg4, _zzq_arg5) \

140 /* The following defines the magic code sequences which the JITter
141  spots and handles magically. Don't look too closely at them as
142  they will rot your brain.
143 
144  The assembly code sequences for all architectures is in this one
145  file. This is because this file must be stand-alone, and we don't
146  want to have multiple files.
147 
148  For VALGRIND_DO_CLIENT_REQUEST, we must ensure that the default
149  value gets put in the return slot, so that everything works when
150  this is executed not under Valgrind. Args are passed in a memory
151  block, and so there's no intrinsic limit to the number that could
152  be passed, but it's currently five.
153 
154  The macro args are:
155  _zzq_rlval result lvalue
156  _zzq_default default value (result returned when running on real CPU)
157  _zzq_request request code
158  _zzq_arg1..5 request params
159 
160  The other two macros are used to support function wrapping, and are
161  a lot simpler. VALGRIND_GET_NR_CONTEXT returns the value of the
162  guest's NRADDR pseudo-register and whatever other information is
163  needed to safely run the call original from the wrapper: on
164  ppc64-linux, the R2 value at the divert point is also needed. This
165  information is abstracted into a user-visible type, OrigFn.
166 
167  VALGRIND_CALL_NOREDIR_* behaves the same as the following on the
168  guest, but guarantees that the branch instruction will not be
169  redirected: x86: call *%eax, amd64: call *%rax, ppc32/ppc64:
170  branch-and-link-to-r11. VALGRIND_CALL_NOREDIR is just text, not a
171  complete inline asm, since it needs to be combined with more magic
172  inline asm stuff to be useful.

1045 /* NB 9 Sept 07. There is a nasty kludge here in all these CALL_FN_
1046  macros. In order not to trash the stack redzone, we need to drop
1047  %rsp by 128 before the hidden call, and restore afterwards. The
1048  nastyness is that it is only by luck that the stack still appears
1049  to be unwindable during the hidden call - since then the behaviour
1050  of any routine using this macro does not match what the CFI data
1051  says. Sigh.
1052 
1053  Why is this important? Imagine that a wrapper has a stack
1054  allocated local, and passes to the hidden call, a pointer to it.
1055  Because gcc does not know about the hidden call, it may allocate
1056  that local in the redzone. Unfortunately the hidden call may then
1057  trash it before it comes to use it. So we must step clear of the
1058  redzone, for the duration of the hidden call, to make it safe.
1059 
1060  Probably the same problem afflicts the other redzone-style ABIs too
1061  (ppc64-linux, ppc32-aix5, ppc64-aix5); but for those, the stack is
1062  self describing (none of this CFI nonsense) so at least messing
1063  with the stack pointer doesn't give a danger of non-unwindable
1064  stack. */

3807 /* Several Valgrind tools (Memcheck, Massif, Helgrind, DRD) rely on knowing
3808  when heap blocks are allocated in order to give accurate results. This
3809  happens automatically for the standard allocator functions such as
3810  malloc(), calloc(), realloc(), memalign(), new, new[], free(), delete,
3811  delete[], etc.
3812 
3813  But if your program uses a custom allocator, this doesn't automatically
3814  happen, and Valgrind will not do as well. For example, if you allocate
3815  superblocks with mmap() and then allocates chunks of the superblocks, all
3816  Valgrind's observations will be at the mmap() level and it won't know that
3817  the chunks should be considered separate entities. In Memcheck's case,
3818  that means you probably won't get heap block overrun detection (because
3819  there won't be redzones marked as unaddressable) and you definitely won't
3820  get any leak detection.
3821 
3822  The following client requests allow a custom allocator to be annotated so
3823  that it can be handled accurately by Valgrind.
3824 
3825  VALGRIND_MALLOCLIKE_BLOCK marks a region of memory as having been allocated
3826  by a malloc()-like function. For Memcheck (an illustrative case), this
3827  does two things:
3828 
3829  - It records that the block has been allocated. This means any addresses
3830  within the block mentioned in error messages will be
3831  identified as belonging to the block. It also means that if the block
3832  isn't freed it will be detected by the leak checker.
3833 
3834  - It marks the block as being addressable and undefined (if 'is_zeroed' is
3835  not set), or addressable and defined (if 'is_zeroed' is set). This
3836  controls how accesses to the block by the program are handled.
3837 
3838  'addr' is the start of the usable block (ie. after any
3839  redzone), 'sizeB' is its size. 'rzB' is the redzone size if the allocator
3840  can apply redzones -- these are blocks of padding at the start and end of
3841  each block. Adding redzones is recommended as it makes it much more likely
3842  Valgrind will spot block overruns. `is_zeroed' indicates if the memory is
3843  zeroed (or filled with another predictable value), as is the case for
3844  calloc().
3845 
3846  VALGRIND_MALLOCLIKE_BLOCK should be put immediately after the point where a
3847  heap block -- that will be used by the client program -- is allocated.
3848  It's best to put it at the outermost level of the allocator if possible;
3849  for example, if you have a function my_alloc() which calls
3850  internal_alloc(), and the client request is put inside internal_alloc(),
3851  stack traces relating to the heap block will contain entries for both
3852  my_alloc() and internal_alloc(), which is probably not what you want.
3853 
3854  For Memcheck users: if you use VALGRIND_MALLOCLIKE_BLOCK to carve out
3855  custom blocks from within a heap block, B, that has been allocated with
3856  malloc/calloc/new/etc, then block B will be *ignored* during leak-checking
3857  -- the custom blocks will take precedence.
3858 
3859  VALGRIND_FREELIKE_BLOCK is the partner to VALGRIND_MALLOCLIKE_BLOCK. For
3860  Memcheck, it does two things:
3861 
3862  - It records that the block has been deallocated. This assumes that the
3863  block was annotated as having been allocated via
3864  VALGRIND_MALLOCLIKE_BLOCK. Otherwise, an error will be issued.
3865 
3866  - It marks the block as being unaddressable.
3867 
3868  VALGRIND_FREELIKE_BLOCK should be put immediately after the point where a
3869  heap block is deallocated.
3870 
3871  In many cases, these two client requests will not be enough to get your
3872  allocator working well with Memcheck. More specifically, if your allocator
3873  writes to freed blocks in any way then a VALGRIND_MAKE_MEM_UNDEFINED call
3874  will be necessary to mark the memory as addressable just before the zeroing
3875  occurs, otherwise you'll get a lot of invalid write errors. For example,
3876  you'll need to do this if your allocator recycles freed blocks, but it
3877  zeroes them before handing them back out (via VALGRIND_MALLOCLIKE_BLOCK).
3878  Alternatively, if your allocator reuses freed blocks for allocator-internal
3879  data structures, VALGRIND_MAKE_MEM_UNDEFINED calls will also be necessary.
3880 
3881  Really, what's happening is a blurring of the lines between the client
3882  program and the allocator... after VALGRIND_FREELIKE_BLOCK is called, the
3883  memory should be considered unaddressable to the client program, but the
3884  allocator knows more than the rest of the client program and so may be able
3885  to safely access it. Extra client requests are necessary for Valgrind to
3886  understand the distinction between the allocator and the rest of the
3887  program.
3888 
3889  Note: there is currently no VALGRIND_REALLOCLIKE_BLOCK client request; it
3890  has to be emulated with MALLOCLIKE/FREELIKE and memory copying.
