[PATCH] D71726: Let clang atomic builtins fetch add/sub support floating point types

[Yaxun Liu via Phabricator via cfe-commits]

yaxunl added a comment.

If the concern is that diagnose fp atomics as unsupported hinders middle end and backend work for fixing fp atomic issues, how about adding a -fenable-fp-atomics to clang which can override target info about fp atomics support.
