[PATCH] D130869: [AMDGPU] Add GCNMaxILPSchedStrategy

[Jay Foad via Phabricator via llvm-commits]

foad added a comment.

Is scheduling for maximum ILP the same thing as scheduling for minimum latency?

Does this patch have anything in common with lib/Target/AMDGPU/GCNILPSched.cpp? (Is that even maintained?)

Oh I see. I somehow missed that change in AMDGPUTargetMachine.cpp.
