2016-05-18[LSAN] Fix test swapcontext.cc on MIPSSagar Thakur
There is no frame validity check in the slow unwinder like there is in the fast unwinder due to which lsan reports a leak even for heap allocated coroutine in the test swapcontext.cc. Since mips/linux uses slow unwindwer instead of fast unwinder, the test fails for mips/linux. Therefore adding the checks before unwinding fixes the test for mips/linux. Reviewed by aizatsky.

2015-10-01[compiler-rt] Apply modernize-use-nullptr fixes in sanitizersVedant Kumar
- Trim spaces. - Use nullptr in place of 0 for pointer variables. - Use '!p' in place of 'p == 0' for null pointer checks. - Add blank lines to separate function definitions. - Add 'extern "C"' or 'namespace foo' comments after the appropriate closing brackets This is a continuation of work from 409b7b82. The focus here is on the various sanitizers (not sanitizer_common, as before). Patch by Eugene Zelenko!

Summary: Introduce __asan::malloc_context_size atomic that is used to determine required malloc/free stack trace size. It is initialized with common_flags()->malloc_context_size flag, but can later be overwritten at runtime (e.g. when ASan is activated / deactivated).

2014-10-26[Sanitizer] Make StackTrace a lightweight reference to array of PCs, andAlexey Samsonov
introduce a BufferedStackTrace class, which owns this array. Summary: This change splits __sanitizer::StackTrace class into a lightweight __sanitizer::StackTrace, which doesn't own array of PCs, and BufferedStackTrace, which owns it. This would allow us to simplify the interface of StackDepot, and eventually merge __sanitizer::StackTrace with __tsan::StackTrace. Test Plan: regression test suite.

Allows to specify the unwinder to use for CHECK failures. Previous behaviour was to use the "fatal" unwinder. As compiler-rt is built without frame pointers, only the slow unwinder really makes sense here, and it is the default. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@219677 91177308-0d34-0410-b5e6-96231b3b80d8

2014-02-11[sanitizer] Use system unwinder in signal handlers on Android.Evgeniy Stepanov
Because of the way Bionic sets up signal stack frames, libc unwinder is unable to step through it, resulting in broken SEGV stack traces. Luckily, libcorkscrew.so on Android implements an unwinder that can start with a signal context, thus sidestepping the issue. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@201151 91177308-0d34-0410-b5e6-96231b3b80d8
