[PATCH] D78647: [MLIR] Lower GenericAtomicRMWOp to llvm.cmpxchg.

[Frank Laub via Phabricator via llvm-commits]

flaub added a comment.

OK, I could see always lowering enums that would lower to `cmpxchg` via the generic op. But at the moment we have a higher layer that uses the enumerated version for min/max, so I'd prefer to don't remove that. It's much easier to pattern match (even declaratively) the enumerated version than the one with a region.
