Timur Iskhodzhanov f2061453bd [ASan] Remove one FIXME - re-enable "free-not-malloced" reports on Windows 
llvm-svn: 151051
 2012-02-21 09:58:39 +00:00
Alexander Potapenko 0be25d562c Check that the FakeStack size is non-zero before looking into it. 
Sometimes DescribeStackAddress is called before another thread's FakeStack is initialized, which could previously cause a check to fire.

Alexander Potapenko c97434ecaf Disable wrapping memcpy() on Mac OS Lion, where it 
actually falls back to memmove.
In this case we still need to initialize real_memcpy, so we set it to

Leopard and Lion are supported.

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!)

Alexander Potapenko bd53f597de This patch adds two methods, __asan_allocate_island and __asan_deallocate_island 
and switches our interceptors to using them instead of the default
vm_allocate-based approach used by mach_override_ptr.

To simplify the code, a fixed memory mapping is used for the allocation pool --
note that we can't mmap an arbitrary chunk of memory, because the shadow memory hasn't been mapped yet
(for the reasons discussed in http://code.google.com/p/address-sanitizer/issues/detail?id=24, we cannot map the shadow earlier)

The patch drops the program startup time from several second to half a second,
which speeds up the execution of ASan tests noticeably.
Because of the virtual memory size occupied by the programs it's hard
to speed up the shutdown time, which would've also helped the tests.

Alexander Potapenko 553c208d22 This patch moves the code reading /proc/self/environ into AsanGetEnv 
in asan_linux.cc, because /proc is unavailable on Mac.
Instead the Mac version of AsanGetEnv iterates over the array of
environment variables obtained from _NSGetEnviron()

Kostya Serebryany 8b981c2564 The code instrumented with ASan may have its own instance of the 
mach_override library.
In this case chances are that functions from it will be called from
mach_override_ptr() during ASan initialization.
This may lead to crashes (if those functions are instrumented) or
incorrect behavior (if the implementations differ).

The attached patch renames mach_override_ptr() into
__asan_mach_override_ptr() and makes the rest of the mach_override
internals hidden.
The corresponding AddressSanitizer bug is
