--- Comment #4 from Marc Glisse <glisse at gcc dot gnu.org> ---
I am starting a bootstrap+regtest with:
/* (X ^ Y) ^ (X ^ Z) -> Y ^ Z */
(simplify
(bit_xor (convert1? (bit_xor:c @0 @1)) (convert2? (bit_xor:c @0 @2)))
(if (tree_nop_conversion_p (type, TREE_TYPE (@1))
&& tree_nop_conversion_p (type, TREE_TYPE (@2)))
- (convert (bit_xor @1 @2))))
+ (bit_xor (convert @1) (convert @2))))
