[PATCH] D37981: AMDGPU: Start selecting s_xnor_{b32, b64}

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added inline comments.


================
Comment at: lib/Target/AMDGPU/SOPInstructions.td:396
+def S_XNOR_B32 : SOP2_32 <"s_xnor_b32",
+  [(set i32:$sdst, (xor (xor_oneuse i32:$src0, i32:$src1), (i32 -1)))]
+>;
----------------
Minor clean would be not use the not PatFrag rather than xor -1 yourself
