[Openmp-commits] [PATCH] D45890: [OMPT] Add implementation and tests of Archer tool

[Joachim Protze via Phabricator via Openmp-commits]

The tool provides TSAN annotations for OpenMP synchronization. Enabled for 
application execution by setting OMP_TOOL_LIBRARIES=libarcher.so, this
library should get installed in the same order as libomp, so the linker
should find the file when the application is linked with OpenMP.

The tool detects whether the application was built with TSan and rejects
activation according to the OMPT protocol if there is no TSan-rt.

      

Further it is recommended to set
TSAN_OPTIONS="ignore_noninstrumented_modules=1"
This avoids some false positive errors from the OpenMP runtime.
