actually falls back to memmove.
In this case we still need to initialize real_memcpy, so we set it to
real_memmove
We check for MACOS_VERSION_SNOW_LEOPARD, because currently only Snow
Leopard and Lion are supported.

where memcpy() in fact aliases memmove() and thus calling it with
overlapping parameters is not an error.

[asan] fix the wrong __WORDSIZE definition on Win x64, add ASAN_INTERFACE_FUNCTION_ATTRIBUTE. Patch by timurrrr@google.com

Patch by Timur Iskhodzhanov (timurrrr@google.com)

To test:
$ cl /c *.c*
in the asan directory.

The code fails to link if you omit the "/c" part but that's one of the
next steps,
as well as a few TODO's I've put into the Windows-specific code.

The double-extern thing is
http://llvm.org/bugs/show_bug.cgi?id=11869

And the #include <string[s].h> are only needed on Mac (see comments in
the original code)
and also including them might make strchr/index conflict with the g++
system headers (which don't follow the man pages, ouch!)

llvm-svn: 149129

These should fix the output tests on Mac.

llvm-svn: 149068

More Linux-like output on Mac (to match more output tests).

llvm-svn: 149064

Fix a bug in AsanProcMaps on Mac: on 64 bits the program was trying to read twice as many segment load commands as the binary actually contained.

llvm-svn: 149063

Add the DEBUG flag to test_output.sh

This should fix http://code.google.com/p/address-sanitizer/issues/detail?id=10

llvm-svn: 148696

Normally this function should not create copies of constant strings, but it does when the default CFAllocator
is replaced (e.g. under AddressSanitizer)

This test is related to http://code.google.com/p/address-sanitizer/issues/detail?id=10

llvm-svn: 148474

 -- make the load command scan linear (instead of quadratic)
 -- do not create a nested AsanProcMaps instance for each address lookup
 -- more comments

llvm-svn: 148472

The change removes the unused FLAG_fast_unwind, and forces EHABI-based unwind
on ARM, and fast (FP-based) unwind everywhere else.

llvm-svn: 148394

llvm-svn: 148386

Implement AsanProcMaps for Mac OS. The code from sysinfo/ is not needed anymore and should be cleaned up.

llvm-svn: 148385

[asan] workaround for bug http://llvm.org/bugs/show_bug.cgi?id=11763. Do not bark on memcpy(a, a, size).

AddressSanitizer: from this patch, ASan allocator returns false for __asan_get_ownership(NULL) and produce error reports for malloc_usable_size(NULL) and __asan_get_allocated_size(NULL)
