Alexey Samsonov 9585613334 [ASan] fixes for Android build 
llvm-svn: 172800
 2013-01-18 09:20:06 +00:00
Kostya Serebryany 69fe0ba415 [sanitizer] reapply r172719, r172721-172723, r172725, and also fix the warning on Mac. 
llvm-svn: 172791
 2013-01-18 06:43:13 +00:00
Jakob Stoklund Olesen 7956e0094d Revert r172719, r172721-172723, and r172725. 
The r172719 patch broke the build on Mac, the others depended on it.

compiler-rt/lib/asan/asan_interceptors.cc:78:13: error: unused function
      'SetThreadName' [-Werror,-Wunused-function]
      static void SetThreadName(const char *name) {

Orignal headlines:

  [asan] attempting to fix the Mac build
  [asan] restructure read/pread/pread64 tests
  [sanitizer] move write/pwrite/pwrite64 interceptors to common
  [msan] start using common interceptors in msan
  [tsan] move prctl interceptor from asan to common_interceptors thus enabling it for tsan too

Peter Collingbourne 6600516a58 Have ReExec read environment from /proc/self/environ 
It is possible for ReExec to be called before the C standard library
has initialised itself sufficiently for execv to work properly.
Fix this by parsing the environment ourselves and using execve.

Will Dietz 9d3209b5c7 [ubsan] Use __sanitizer::atomic_exchange(), prefer shared impl. 
Specify weaker memory order in case we optimize for it in the future,
presently still doing same __sync_lock_test_and_set() as before.

Change suggested by Alexey Samsonov, thanks!
