gimplify.c (gimplify_expr): Gimplify TRUTH_NOT_EXPR as BIT_XOR_EXPR, same as the RTL expander does.
2011-07-19 Richard Guenther <rguenther@suse.de>
* gimplify.c (gimplify_expr): Gimplify TRUTH_NOT_EXPR as
BIT_XOR_EXPR, same as the RTL expander does.
* tree-cfg.c (verify_expr): Disallow TRUTH_NOT_EXPR in the gimple IL.
(verify_gimple_assign_unary): Likewise.
* tree-ssa-propagate.c (valid_gimple_rhs_p): Disallow TRUTH_*_EXPR.
* tree-ssa-forwprop.c (forward_propagate_comparison): Handle
BIT_NOT_EXPR and BIT_XOR_EXPR instead of TRUTH_NOT_EXPR.
* gcc.dg/tree-ssa/bool-10.c: Adjust expected pattern.
* gcc.dg/tree-ssa/bool-11.c: Likewise.
* gcc.dg/torture/20110719-1.c: New testcase.
