2016-07-14[compiler-rt] Add internal wcslen to avoid crashing on windows 64-bitsEtienne Bergeron
Summary: The function wcslen is incorrectly hooked on windows 64-bits. The interception library is not able to hook without breaking the code. The function is too small and the interception must be done with trampoline-hooking which turned out to be incorrect on a small loop (first few instructions have a backedge).

2015-11-20[compiler-rt] Add internal implementations for strlcat and strlcpyAnna Zaks
The compiler-rt should make use of strlcpy() rather than strncpy(). Using internal_strncpy() may be fine with appropriate bounds checking or enforcement of nul-termination elsewhere, but it's just good practice these days to avoid using strncpy() in new code.

2015-02-06[compiler-rt] Make MaybeReexec properly process DYLD_INSERT_LIBRARIES when ↵Kuba Brecka
using non-absolute paths MaybeReexec() in asan_mac.cc checks for presence of the ASan dylib in DYLD_INSERT_LIBRARIES, and if it is there, it will process this env. var. and remove the dylib from its value, so that spawned children don't have this variable set. However, the current implementation only works when using a canonical absolute path to the dylib, it fails to remove the dylib for example when using @executable_path. This patch changes the processing of DYLD_INSERT_LIBRARIES to comparing values only based on filenames (ignoring directories).

2014-11-21[ASan] Get fake stack code working with GCC 4.8.2.Jay Foad
Summary: TestCases/Linux/heavy_uar_test.cc was failing on my PowerPC64 box with GCC 4.8.2, because the compiler recognised a memset-like loop and turned it into a call to memset, which got intercepted by __asan_memset, which got upset because it was being called on an address in high shadow memory. Use break_optimization to stop the compiler from doing this.
