--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
The scalar is handled by match:
(for code1 (eq ne)
(for code2 (eq ne lt gt le ge)
(simplify
(bit_ior:c (code1:c@3 @0 @1) (code2:c@4 (convert?@c0 @0) @2))
(if ((TREE_CODE (@1) == INTEGER_CST
&& TREE_CODE (@2) == INTEGER_CST)
|| ((INTEGRAL_TYPE_P (TREE_TYPE (@1))
|| POINTER_TYPE_P (TREE_TYPE (@1)))
&& bitwise_equal_p (@1, @2)))
I suspsect s/INTEGRAL_TYPE_P/ANY_INTEGRAL_TYPE_P/ here is enough for integral
types.
