Better not modify copy/paster files otherwise this will regress again
later. It's better to not include valgrind.h at all when using MSVC.
This reverts commit bbcce75d4e.

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.

guaranteed-no-redirection macros, so as to get from function

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.

/* 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

/* 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); 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. */

/* 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.

The flag VALGRIND_MEMPOOL_METAPOOL specifies that the pieces of memory

|
by the application as superblocks to dole out MALLOC_LIKE blocks using

|
VALGRIND_MALLOCLIKE_BLOCK. In other words, a meta pool is a "2 levels"

pool : first level is the blocks described by VALGRIND_MEMPOOL_ALLOC.
|
|
The second level blocks are described using VALGRIND_MALLOCLIKE_BLOCK.
|
|
Note that the association between the pool and the second level blocks
|
|
is implicit : second level blocks will be located inside first level
|
|
blocks. It is necessary to use the VALGRIND_MEMPOOL_METAPOOL flag
|
|
for such 2 levels pools, as otherwise valgrind will detect overlapping
|
|
memory blocks, and will abort execution (e.g. during leak search).
|
|
|
|
Such a meta pool can also be marked as an 'auto free' pool using the flag
|
|
VALGRIND_MEMPOOL_AUTO_FREE, which must be OR-ed together with the

VALGRIND_MEMPOOL_METAPOOL. For an 'auto free' pool, VALGRIND_MEMPOOL_FREE

|
will automatically free the second level blocks that are contained

|
inside the first level block freed with VALGRIND_MEMPOOL_FREE.
|
|
In other words, calling VALGRIND_MEMPOOL_FREE will cause implicit calls
|
|
to VALGRIND_FREELIKE_BLOCK for all the second level blocks included
|
|
in the first level block.
|
|
Note: it is an error to use the VALGRIND_MEMPOOL_AUTO_FREE flag
|
|
without the VALGRIND_MEMPOOL_METAPOOL flag.
