[tsan] Enable ignore_noninstrumented_modules=1 on Darwin by default TSan recently got the "ignore_noninstrumented_modules" flag, which disables tracking of read and writes that come from noninstrumented modules (via interceptors). This is a way of suppressing false positives coming from system libraries and other noninstrumented code. This patch turns this on by default on Darwin, where it's supposed to replace the previous solution, "ignore_interceptors_accesses", which disables tracking in all interceptors. The new approach should re-enable TSan's ability to find races via interceptors on Darwin. Differential Revision: https://reviews.llvm.org/D29041 llvm-svn: 292981 2017-01-25 05:37:50 +08:00
