llvm-svn: 180184
 2013-04-24 11:16:47 +00:00
Dmitry Vyukov beaf786151 tsan: disable getpwuid_r() and glob64() interceptors under tsan, because they cause interceptor recursion if user intercepts fopen()

Alexey Samsonov 6021e94774 [TSan] Allocate fd table in user heap instead of using internal allocator. We need this to catch races on fds.

Chandler Carruth 2b3c00eec7 Revert r179012: "[msan] Intercept glob()." 
This was committed without tests and contains obvious bugs. That's not
acceptable. It broke address sanitizer for most programs using glob(3).

 2013-03-26 12:40:23 +00:00
Alexander Potapenko f8109dd0f8 [libsanitizer] Unmapping the old cache partially invalidates the memory layout, so add
