Instead of checking stack limits that are not well defined for the main thread,
we rely on siginfo::si_code and distance from SP.

There are more cases when those manifest as an access below SP.

llvm-svn: 201664

Move asm tests to their own file.

These are runtime support functions for inline assembly instrumentation.
This is a re-submit of r201402.

This change allows to build compiler-rt libraries separately from
LLVM/Clang (path to LLVM build directory should be specified at
configure time). Running tests is not yet supported.

[tsan] in deadlock detector do not register locks on their creation and unregister them on destruction; added a relevant test

llvm-svn: 201568

Report segmentation faults near or below stack bottom as stack-overflow
(not stack-buffer-overflow!).

llvm-svn: 201565

Android libc always sets altstack on non-main threads, but it is too small for
our unwinder. With use_sigaltstack=1, override this setting with a larger one.

llvm-svn: 201557

[CMake] Add top-level target for each compiler-rt library, and add 'compiler-rt' target encompassing them all.

This fixes global-demangle.cc test on Android.

[tsan] rudimentary support for deadlock detector in tsan (nothing really works yet except for a single tiny test). Also rename tsan's DeadlockDetector to InternalDeadlockDetector

llvm-svn: 201407

llvm-svn: 201406

[sanitizer] add iterators to bit vectors; make bit vector operations use little stack; add common flag 'detect_deadlocks'

This is covered by existing ASan test.
This does not change anything for TSan by default (but provides a flag to 
change the threshold size).
