[PATCH] D96517: [AMDGPU] Optimize SGPR to scratch spilling

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added a comment.

I think once we're spilling SGPRs to memory with these tricks, you've given up on performance. We just need *anything* that works, and put effort into guaranteeing we never need to do this (aside from the degenerate inline-asm case using all VGPRs). I'm not worried about getting the ideal SGPR-to-memory sequence
