[PATCH] D102486: Use a non-recursive mutex in GsymCreator.

[Simon Giesecke via Phabricator via llvm-commits]

simon.giesecke added a comment.

GSYM convertion still spends a significant time for locking in `GsymCreator::insertString` even with only 8 threads, so lock contention seems to be generally an issue here. I was wondering if we could avoid locking the mutex here, but using thread-local tables until finalization does not seem to be feasible since any thread might insert the same string IIUC and we want to have unique IDs at this point. A lock-free map might be an alternative here, though?
