[PATCH] D96336: [AMDGPU] Save VGPR of whole wave when spilling

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added inline comments.


================
Comment at: llvm/lib/Target/AMDGPU/SIInstructions.td:117-118
+// be live in a currently inactive lane, but LLVM does not track this.
+def FAKE_DEF : PseudoInstSI <(outs unknown:$vdst), (ins),
+  [], ";;#FAKE_DEF $vdst">;
+
----------------
I think a better name would be something like COPY_INACTIVE_LANES or something like that?
