jyknight added a comment. I still have the same fundamental objection as before to the parts of this patch for prohibiting FP add/sub on some targets.
If a particular LLVM target cannot handle transforming an FP add/sub (or any other RMW operations!) into the correct cmpxchg or LL/SC loop, that's a bug in the backend which should be fixed. I don't see why we ought to add a bunch of functionality in the frontend to workaround this? (Some of the other changes, e.g. to diagnose lack of support for large atomics is useful, though.)
