For more context see:https://groups.google.com/forum/#!topic/thread-sanitizer/ecH2P0QUqPsThe added test captures this pattern.While we are here rename ThreadTid to ThreadConsumeTid to make it clear thatit's not just a "getter", it resets user_id to 0. This lead to confusion recently.Reviewed in https://reviews.llvm.org/D74828 List of files: /llvm-project-15.0.7/compiler-rt/test/tsan/ignore_lib6.cpp.supp Wed, 19 Feb 2020 13:18:53 +0000 Dmitry Vyukov <dvyukov@google.com>
