Alexander Potapenko fefc1e989c If the program is linked to a dynamic ASan runtime which is not present in DYLD_INSERT_LIBRARIES 
(which, in turn, is required for our interceptors to take effect), re-exec the program with
DYLD_INSERT_LIBRARIES set.

Alexander Potapenko 51e6488b31 Intercept CFAllocator for each thread in the program. 
Test that child threads use the ASan allocator, that allocated memory can be passed to another thread and deallocated on it.
This should fix http://code.google.com/p/address-sanitizer/issues/detail?id=81

 2012-05-22 11:54:44 +00:00
Evgeniy Stepanov 4cc2631c7d Avoid including link.h. 
It's not available on Android. We only use this header to find out if _DYNAMIC
is present; declaring it "extern void*" does the trick.

Evgeniy Stepanov 84c44a8b8b EHABI-based stack trace on ARM. 
The change removes the unused FLAG_fast_unwind, and forces EHABI-based unwind
on ARM, and fast (FP-based) unwind everywhere else.

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()
