Introduce DDetector interface between the tool and the DD itself.
It will help to experiment with other DD implementation,
as well as reuse DD in other tools.

[sanitizer] do not acquire a global mutex in deadlock detector when dealing with Unlock (it is essentially a thread-local operation)

llvm-svn: 202401

this fixes obscure false positives
see the comments and the test for details

llvm-svn: 202400

we must go deeper!

[sanitizer] fix epoch handling in deadlock detector (before the fix, we could have had edges from locks in the previous epoch to locks in the current epoch)

AdjustStackSizeLinux() is used in Lsan, Tsan and Msan non-Linux-specific code so it seems it should have more generic name and moved to a common scope.
Renamed to AdjustStackSize.
Patch by Viktor Kutuzov.

error: address of array 'tctx->name' will always evaluate to 'true'

This reverts commit r201910.

While __func__ may be standard in C++11, it was only recently added to
MSVC in 2013 CTP, and LLVM supports MSVC 2012.  __FUNCTION__ may not be
standard, but it's *very* portable.

[tsan] add coarse-grained lock around the DeadlockDetector. We can do better than that, but that's a start.

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

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

[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

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).
