Comment at: lib/Target/AMDGPU/SOPInstructions.td:561
 
-  let isCommutable = 1 in {
-    def S_MUL_HI_U32 : SOP2_32<"s_mul_hi_u32",
-      [(set i32:$sdst, (UniformBinFrag<mulhu> SSrc_b32:$src0, SSrc_b32:$src1))]>;
-    def S_MUL_HI_I32 : SOP2_32<"s_mul_hi_i32",
-      [(set i32:$sdst, (UniformBinFrag<mulhs> SSrc_b32:$src0, SSrc_b32:$src1))]>;
-  }
+  def S_MUL_HI_U32 : SOP2_32<"s_mul_hi_u32">;
+  def S_MUL_HI_I32 : SOP2_32<"s_mul_hi_i32">;
----------------
Actually it is still isCommutable, even if you drop the pattern.
