[PATCH] D125349: [Sema] Fix crash for C11 atomic in gnu++ mode

[Akira Hatanaka via Phabricator via cfe-commits]

ahatanak added a comment.

Is it not possible to handle this similarly to `volatile unsigned`? If I replace `_Atomic unsigned` with `volatile unsigned`, I see `LookupOverloadedBinOp` succeed without having to strip volatile because `addAssignmentArithmeticOverloads` adds candidates with volatile types.
