+; CHECK-NEXT:    [[RES:%.*]] = tail call <12 x double> @llvm.matrix.multiply.v12f64.v15f64.v20f64(<15 x double> [[A]], <20 x double> [[B:%.*]], i32 3, i32 5, i32 4)
+; CHECK-NEXT:    [[TMP1:%.*]] = fneg <12 x double> [[RES]]
 ; CHECK-NEXT:    store <15 x double> [[A_NEG]], ptr [[A_LOC:%.*]], align 128
----------------
We added an fneg to this sequence without removing the existing one. How is this better?
