[PATCH] D26897: AMDGPU: Refactor immediate folding logic

[Matt Arsenault via llvm-commits]

arsenm added a comment.

This will help for short term making 16-bit operands correct, but longer term it might be better to look at use instructions and finding the operand defs. Right now there seem to be some mis-optimizations when multiple operands might be able to be folded into the same instruction, and the wrong operand is selected
