re PR middle-end/68067 (Wrong constant folding)
2015-10-28 Richard Biener <rguenther@suse.de>
PR middle-end/68067
* fold-const.c (negate_expr_p): We cannot negate plus or minus
if overflow is not wrapping. Likewise multiplication unless
one operand is constant and not power of two.
(fold_negate_expr): Adjust accordingly.
* gcc.dg/torture/pr68067-1.c: New testcase.
* gcc.dg/torture/pr68067-2.c: Likewise.
