Alexey Samsonov 1cb684381a [Sanitizer] Add generic ThreadRegistry class for sanitizer runtimes. This class holds basic thread bookkeeping logic and allows specific sanitizer runtimes to create thread contexts and mark threads as created/running/joined etc. The class is based on the way we currently store thread contexts in TSan.

llvm-svn: 176804
 2013-03-11 13:36:39 +00:00
Alexander Potapenko 18c916c6c5 [ASan] Try to use a small (512 bytes) stack-local buffer in Report() for short messages, fall back to MmapOrDie() in the case of a failure. 
This shall eliminate most of the cryptic "ERROR: failed to mmap" messages caused by recursively calling MmapOrDie() from MmapOrDie().
