[PATCH] D129089: [BOLT] Fix concurrency bugs in the instrumentation runtime

[Vladislav Khmelevsky via Phabricator via llvm-commits]

yota9 added a comment.

@ayermolo The runtime libs such as instrumentation must not depend on external libraries like libstdc++. But in our (currently internal) implementation we are using __atomic_test_and_set, I think it is better option here which eliminates inline asm usage and is arch independent
