[PATCH] D35299: [AArch64] Tie source and destination operands for AESMC/AESIMC.

[Florian Hahn via Phabricator via llvm-commits]

fhahn added a comment.

The previous patch had a smaller diff and was simpler, because it added the constraint to all AESMC/AESIMC instructions. The latest version of the patch only applies the constraint to AESMC/AESIMC instructions that are part of a pair and for targets with FeatureFuseAES, so the impact on the generated code is smaller. I think applying the constraint only to instruction pairs is nice, but I would be fine with adding the constraint to all AESMC/AESIMC instructions too.
