 def : Pat<(fma (fneg v4f64:$A), v4f64:$C, v4f64:$B),
-          (QVFNMSUB $A, $B, $C)>;
+          (QVFNMSUB $A, $C, $B)>;
 def : Pat<(fma v4f64:$A, (fneg v4f64:$C), v4f64:$B),
----------------
This is not right as we didn't respect the nsz flag here. But it is not relative with this patch. D76585 miss to handle the QPX. @qiucf
