[PATCH] D105836: [AMDGPU] Add TII::isAmbientPhysRegUse() to allow VOP rematerialization

[Krzysztof Parzyszek via Phabricator via llvm-commits]

kparzysz added a comment.

Then either implement "isRematerializableUse", and add support for rematerializing it that does nothing for your target, or change it to something like "isIgnorableUse".

What I'm trying to accomplish is to make it applicable to other targets as well, so I'm trying to classify it as a special case of an issue that can occur elsewhere.
