re PR tree-optimization/59245 (ICE on valid code at -O3 on x86_64-linux-gnu in set_value_range, at tree-vrp.c:443)
2013-11-26 Richard Biener <rguenther@suse.de>
PR tree-optimization/59245
* tree-vrp.c (set_value_range): Assert that we don't have
overflowed constants (but our infinities).
(set_value_range_to_value): Drop all overflow flags.
(vrp_visit_phi_node): Likewise.
(vrp_visit_assignment_or_call): Use set_value_range_to_value
to set a constant range.
* gcc.dg/torture/pr59245.c: New testcase.
