fold-const.c (fold): Optimize ~X|X and X|~X as -1.
...
* fold-const.c (fold) <BIT_IOR_EXPR>: Optimize ~X|X and X|~X as -1.
<BIT_XOR_EXPR>: Optimize ~X|X and X|~X as -1.
<BIT_AND_EXPR>: Optimize ~X&X and X&~X as 0.
<TRUTH_AND_EXPR, TRUTH_ANDIF_EXPR>: Optimize !X&&X and X&&!X as false.
<TRUTH_OR_EXPR, TRUTH_ORIF_EXPR>: Optimize !X||X and !X||X as true.
<TRUTH_XOR_EXPR>: Optimize !X^X and X^X! as true. Now that
TRUTH_XOR_EXPR is a commutative tree code, don't test whether arg0
is a constant.
* gcc.dg/20040527-1.c: New test case.
