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.

/* 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. */

/* 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.
