EricWF added a comment. Does anything actually need this? This interface was never really meant to be complete, just want was needed.

This is a minimal subset of atomic functionality needed to support `std::shared_ptr` and `std::call_once` among other things. All new code should use std::atomic IMO. It's not meant to reinvent the wheel, It's meant to be a portable option for when there is no "wheel" already. Does armv4 need lib calls for atomic operations on "unsigned long"? http://reviews.llvm.org/D13051 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
