[PATCH] D102391: [AMDGPU][GlobalISel] Legalize G_ABS

[Mirko Brkusanin via Phabricator via llvm-commits]

mbrkusanin added a comment.

- Added legalizeABS() as a custom lowering to be used by RegBankSelect.

I don't see a way to add multiple paths to already existing lower() for G_ABS and control which one to use. Not sure if this is the cleaner way of doing it that you had in mind.
