Kostya Serebryany e91930a7e6 [asan] implement an experimental detector of ODR violations. Not tested yet outside of a tiny test, may need tuning. 
llvm-svn: 207210
 2014-04-25 08:58:28 +00:00
Kostya Serebryany 7afc6b2c72 [asan] enable use_sigaltstack by default (this will provide verbose reports on stack-overflow instead of silently crashing with SEGV) 
llvm-svn: 207099
 2014-04-24 11:55:17 +00:00
Kostya Serebryany 8cd3d27879 [asan] disable lsan back. :( -- It appears that quite a few lit tests have leaks and they were not covered by out buildbot 
llvm-svn: 206955
 2014-04-23 08:15:16 +00:00
Kostya Serebryany c9db838267 [asan] enable LeakSanitizer (LSan) by default in asan. This only affects Linux x86_64. LSan has been used in various projects for more than half a year and we now consider it quite stable to be on by default.

 2014-04-22 13:56:56 +00:00
Alexander Potapenko 6e647c13e4 [ASan] Fixed the expectation for Darwin memset test. 
Added a comment about keeping the Linux/Darwin test versions in sync.

 2014-04-22 10:53:57 +00:00
Kostya Serebryany 26c4e96455 [sanitizer] enable check_printf by default for asan and tsan. We've been using this flag for a while and it seems to be stable enough for the rest of the world.

 2014-04-21 11:58:25 +00:00
Kostya Serebryany 498b18a01e [asan] try to harden __tls_get_addr interceptor against signals (no good test still); update the comment in a test. 
llvm-svn: 206367

Alexander Potapenko 65a6c57013 [ASan] Replace a CHECK for mmap_limit_mb with a RAW_CHECK. 
In the case of a CHECK failure the program tries to fork and launch llvm-symbolizer,
but hangs in mz_force_lock because one of the allocator locks is already acquired.

Kostya Serebryany b1232474b2 [asan] try fixing the mmap_limit_mb failure on buildbot (tests pass locally)

 2014-04-14 15:37:02 +00:00
Evgeniy Stepanov 681016b2ea [asan] Do not use lambda in sanitizer lit tests. 
We may be building with a very old C++ library.

 2014-04-14 15:19:07 +00:00
Kostya Serebryany bcfbea6d4e [asan] added internal flag mmap_limit_mb
