re PR tree-optimization/80776 (-Wformat-overflow false positive for %d on integer bounded by __builtin_unreachable)
2017-11-28 Richard Biener <rguenther@suse.de>
PR tree-optimization/80776
* gimple-ssa-evrp-analyze.h (evrp_range_analyzer::set_ssa_range_info):
Declare.
* gimple-ssa-evrp-analyze.c (evrp_range_analyzer::set_ssa_range_info):
New function.
(evrp_range_analyzer::record_ranges_from_incoming_edges):
If the incoming edge is an effective fallthru because the other
edge only reaches a __builtin_unreachable () then record ranges
derived from the controlling condition in SSA info.
(evrp_range_analyzer::record_ranges_from_phis): Use set_ssa_range_info.
(evrp_range_analyzer::record_ranges_from_stmt): Likewise.
* gcc.dg/pr80776-1.c: New testcase.
* gcc.dg/pr80776-2.c: Likewise.
