Locking StackDepotBase fully is very expensive, as 2^20 buckets needs to be locked. Not locking, and unclocking only buckets, needed to be unlocked to avoid deadlocks, increases a chance of data race, when same item can be inserted into table twice. However this is just a small additional memory usage by forked process. _______________________________________________ llvm-branch-commits mailing list llvm-branch-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/llvm-branch-commits
