61  You can use these macros to manipulate and query Valgrind's
62  execution inside your own programs.
63 
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. */

214  they will rot your brain.
215 
216  The assembly code sequences for all architectures is in this one
217  file. This is because this file must be stand-alone, and we don't
218  want to have multiple files.
219 
220  For VALGRIND_DO_CLIENT_REQUEST, we must ensure that the default
221  value gets put in the return slot, so that everything works when
222  this is executed not under Valgrind. Args are passed in a memory
223  block, and so there's no intrinsic limit to the number that could
224  be passed, but it's currently five.
225 
226  The macro args are:
227  _zzq_rlval result lvalue
228  _zzq_default default value (result returned when running on real CPU)
229  _zzq_request request code
230  _zzq_arg1..5 request params
231 
232  The other two macros are used to support function wrapping, and are
233  a lot simpler. VALGRIND_GET_NR_CONTEXT returns the value of the
234  guest's NRADDR pseudo-register and whatever other information is
235  needed to safely run the call original from the wrapper: on
236  ppc64-linux, the R2 value at the divert point is also needed. This
237  information is abstracted into a user-visible type, OrigFn.
238 
239  VALGRIND_CALL_NOREDIR_* behaves the same as the following on the
240  guest, but guarantees that the branch instruction will not be
241  redirected: x86: call *%eax, amd64: call *%rax, ppc32/ppc64:
242  branch-and-link-to-r11. VALGRIND_CALL_NOREDIR is just text, not a
243  complete inline asm, since it needs to be combined with more magic
244  inline asm stuff to be useful.

1576 /* This is all pretty complex. It's so as to make stack unwinding
1577  work reliably. See bug 243270. The basic problem is the sub and
1578  add of 128 of %rsp in all of the following macros. If gcc believes
1579  the CFA is in %rsp, then unwinding may fail, because what's at the
1580  CFA is not what gcc "expected" when it constructs the CFIs for the
1581  places where the macros are instantiated.
1582 
1583  But we can't just add a CFI annotation to increase the CFA offset
1584  by 128, to match the sub of 128 from %rsp, because we don't know
1585  whether gcc has chosen %rsp as the CFA at that point, or whether it
1586  has chosen some other register (eg, %rbp). In the latter case,
1587  adding a CFI annotation to change the CFA offset is simply wrong.
1588 
1589  So the solution is to get hold of the CFA using
1590  __builtin_dwarf_cfa(), put it in a known register, and add a
1591  CFI annotation to say what the register is. We choose %rbp for
1592  this (perhaps perversely), because:
1593 
1594  (1) %rbp is already subject to unwinding. If a new register was
1595  chosen then the unwinder would have to unwind it in all stack
1596  traces, which is expensive, and
1597 
1598  (2) %rbp is already subject to precise exception updates in the
1599  JIT. If a new register was chosen, we'd have to have precise
1600  exceptions for it too, which reduces performance of the
1601  generated code.
1602 
1603  However .. one extra complication. We can't just whack the result
1604  of __builtin_dwarf_cfa() into %rbp and then add %rbp to the
1605  list of trashed registers at the end of the inline assembly
1606  fragments; gcc won't allow %rbp to appear in that list. Hence
1607  instead we need to stash %rbp in %r15 for the duration of the asm,
1608  and say that %r15 is trashed instead. gcc seems happy to go with
1609  that.
1610 
1611  Oh .. and this all needs to be conditionalised so that it is
1612  unchanged from before this commit, when compiled with older gccs
1613  that don't support __builtin_dwarf_cfa. Furthermore, since
1614  this header file is freestanding, it has to be independent of
1615  config.h, and so the following conditionalisation cannot depend on
1616  configure time checks.
1617 
1618  Although it's not clear from
1619  'defined(__GNUC__) && defined(__GCC_HAVE_DWARF2_CFI_ASM)',
1620  this expression excludes Darwin.
1621  .cfi directives in Darwin assembly appear to be completely
1622  different and I haven't investigated how they work.
1623 
1624  For even more entertainment value, note we have to use the
1625  completely undocumented __builtin_dwarf_cfa(), which appears to
1626  really compute the CFA, whereas __builtin_frame_address(0) claims
1627  to but actually doesn't. See

1662  macros. In order not to trash the stack redzone, we need to drop
1663  %rsp by 128 before the hidden call, and restore afterwards. The
1664  nastyness is that it is only by luck that the stack still appears
1665  to be unwindable during the hidden call - since then the behaviour
1666  of any routine using this macro does not match what the CFI data
1667  says. Sigh.
1668 
1669  Why is this important? Imagine that a wrapper has a stack
1670  allocated local, and passes to the hidden call, a pointer to it.
1671  Because gcc does not know about the hidden call, it may allocate
1672  that local in the redzone. Unfortunately the hidden call may then
1673  trash it before it comes to use it. So we must step clear of the
1674  redzone, for the duration of the hidden call, to make it safe.
1675 
1676  Probably the same problem afflicts the other redzone-style ABIs too
1677  (ppc64-linux); but for those, the stack is
1678  self describing (none of this CFI nonsense) so at least messing
1679  with the stack pointer doesn't give a danger of non-unwindable

6350 /* Several Valgrind tools (Memcheck, Massif, Helgrind, DRD) rely on knowing
6351  when heap blocks are allocated in order to give accurate results. This
6352  happens automatically for the standard allocator functions such as
6353  malloc(), calloc(), realloc(), memalign(), new, new[], free(), delete,
6354  delete[], etc.
6355 
6356  But if your program uses a custom allocator, this doesn't automatically
6357  happen, and Valgrind will not do as well. For example, if you allocate
6358  superblocks with mmap() and then allocates chunks of the superblocks, all
6359  Valgrind's observations will be at the mmap() level and it won't know that
6360  the chunks should be considered separate entities. In Memcheck's case,
6361  that means you probably won't get heap block overrun detection (because
6362  there won't be redzones marked as unaddressable) and you definitely won't
6363  get any leak detection.
6364 
6365  The following client requests allow a custom allocator to be annotated so
6366  that it can be handled accurately by Valgrind.
6367 
6368  VALGRIND_MALLOCLIKE_BLOCK marks a region of memory as having been allocated
6369  by a malloc()-like function. For Memcheck (an illustrative case), this
6370  does two things:
6371 
6372  - It records that the block has been allocated. This means any addresses
6373  within the block mentioned in error messages will be
6374  identified as belonging to the block. It also means that if the block
6375  isn't freed it will be detected by the leak checker.
6376 
6377  - It marks the block as being addressable and undefined (if 'is_zeroed' is
6378  not set), or addressable and defined (if 'is_zeroed' is set). This
6379  controls how accesses to the block by the program are handled.
6380 
6381  'addr' is the start of the usable block (ie. after any
6382  redzone), 'sizeB' is its size. 'rzB' is the redzone size if the allocator
6383  can apply redzones -- these are blocks of padding at the start and end of
6384  each block. Adding redzones is recommended as it makes it much more likely
6385  Valgrind will spot block overruns. `is_zeroed' indicates if the memory is
6386  zeroed (or filled with another predictable value), as is the case for
6387  calloc().
6388 
6389  VALGRIND_MALLOCLIKE_BLOCK should be put immediately after the point where a
6390  heap block -- that will be used by the client program -- is allocated.
6391  It's best to put it at the outermost level of the allocator if possible;
6392  for example, if you have a function my_alloc() which calls
6393  internal_alloc(), and the client request is put inside internal_alloc(),
6394  stack traces relating to the heap block will contain entries for both
6395  my_alloc() and internal_alloc(), which is probably not what you want.
6396 
6397  For Memcheck users: if you use VALGRIND_MALLOCLIKE_BLOCK to carve out
6398  custom blocks from within a heap block, B, that has been allocated with
6399  malloc/calloc/new/etc, then block B will be *ignored* during leak-checking
6400  -- the custom blocks will take precedence.
6401 
6402  VALGRIND_FREELIKE_BLOCK is the partner to VALGRIND_MALLOCLIKE_BLOCK. For
6403  Memcheck, it does two things:
6404 
6405  - It records that the block has been deallocated. This assumes that the
6406  block was annotated as having been allocated via
6407  VALGRIND_MALLOCLIKE_BLOCK. Otherwise, an error will be issued.
6408 
6409  - It marks the block as being unaddressable.
6410 
6411  VALGRIND_FREELIKE_BLOCK should be put immediately after the point where a
6412  heap block is deallocated.
6413 
6414  VALGRIND_RESIZEINPLACE_BLOCK informs a tool about reallocation. For
6415  Memcheck, it does four things:
6416 
6417  - It records that the size of a block has been changed. This assumes that
6418  the block was annotated as having been allocated via
6419  VALGRIND_MALLOCLIKE_BLOCK. Otherwise, an error will be issued.
6420 
6421  - If the block shrunk, it marks the freed memory as being unaddressable.
6422 
6423  - If the block grew, it marks the new area as undefined and defines a red
6424  zone past the end of the new block.
6425 
6426  - The V-bits of the overlap between the old and the new block are preserved.
6427 
6428  VALGRIND_RESIZEINPLACE_BLOCK should be put after allocation of the new block
6429  and before deallocation of the old block.
6430 
6431  In many cases, these three client requests will not be enough to get your
6432  allocator working well with Memcheck. More specifically, if your allocator
6433  writes to freed blocks in any way then a VALGRIND_MAKE_MEM_UNDEFINED call
6434  will be necessary to mark the memory as addressable just before the zeroing
6435  occurs, otherwise you'll get a lot of invalid write errors. For example,
6436  you'll need to do this if your allocator recycles freed blocks, but it
6437  zeroes them before handing them back out (via VALGRIND_MALLOCLIKE_BLOCK).
6438  Alternatively, if your allocator reuses freed blocks for allocator-internal
6439  data structures, VALGRIND_MAKE_MEM_UNDEFINED calls will also be necessary.
6440 
6441  Really, what's happening is a blurring of the lines between the client
6442  program and the allocator... after VALGRIND_FREELIKE_BLOCK is called, the
6443  memory should be considered unaddressable to the client program, but the
6444  allocator knows more than the rest of the client program and so may be able
6445  to safely access it. Extra client requests are necessary for Valgrind to
6446  understand the distinction between the allocator and the rest of the
6447  program.
