[PATCH] D66666: [AMDGPU] Remove unnecessary movs for v_fmac operands

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added a comment.

Can you also add a MIR test for this? Also testing the 16-bit case would be nice



================
Comment at: lib/Target/AMDGPU/SIFoldOperands.cpp:512-514
+      if (UseOpc != AMDGPU::V_MAC_F32_e64 &&
+          UseOpc != AMDGPU::V_MAC_F16_e64 &&
+          UseOpc != AMDGPU::V_FMAC_F32_e64)
----------------
Can you fold this opcode list into a canFoldTiedSrcOp (or something similar) predicate function
