[PATCH] D128252: [AMDGPU] VGPR to SGPR copies lowering

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added inline comments.


================
Comment at: llvm/lib/Target/AMDGPU/SIFixSGPRCopies.cpp:575
+  // Is kept aside to process V2S copies before the rest of the stuff
+  lowerVGPR2SGPRCopies(MF);
+
----------------
What's the advantage of splitting this into a separate loop?
