re PR tree-optimization/71595 (ICE on valid code at -O2 and -O3 on x86_64-linux-gnu: in check_loop_closed_ssa_use, at tree-ssa-loop-manip.c:704)
2016-11-24 Richard Biener <rguenther@suse.de>
PR tree-optimization/71595
* cfgloopmanip.h (remove_path): Add irred_invalidated and
loop_closed_ssa_invalidated parameters, defaulted to NULL.
* cfgloopmanip.c (remove_path): Likewise, pass them along to
called functions. Only fix irred flags if the caller didn't
request state.
* tree-ssa-loop-ivcanon.c (unloop_loops): Use add_bb_to_loop.
(unloop_loops): Pass irred_invalidated and loop_closed_ssa_invalidated
to remove_path.
* gcc.dg/torture/pr71595.c: New testcase.
