2017-05-01[ubsan] Fall back to the fast unwinder when print_stacktrace=1Vedant Kumar
This makes it possible to get stacktrace info when print_stacktrace=1 on Darwin (where the slow unwinder is not currently supported [1]). This should not regress any other platforms. [1] The thread about r300295 has a relatively recent discusion about this. We should be able to enable the existing slow unwind functionality for Darwin, but this needs more testing.

These were added in r301016, but they're failing, because -fsanitize=cfi seemingly causes -flto=thin to emit raw bitcode objects, rather than the mach-o-wrapped bitcode we emit with -flto=thin alone.

based on the caller PC We need to make sure that the "external" API isn't dup'ing all data races into a single one (because the stack might look the same) and suppressing all external races.

2017-04-21[tsan] Ignore memory accesses for libignored modules for "external" racesKuba Mracek
On Darwin, the setting ignore_noninstrumented_modules is used to suppress false positives in code that users don't have control of. The recently added "external" API (which can be used to detect races on objects provided by system libraries, but the race is actually user's fault) ignores this flag and it can report issues in non-instrumented modules. This patch fixes that. Differential Revision: https://reviews.llvm.org/D31553 git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@301000 91177308-0d34-0410-b5e6-96231b3b80d8
