re PR tree-optimization/23855 (loop header should also be pulled out of the inner loop too)
2016-08-17 Richard Biener <rguenther@suse.de>
PR tree-optimization/23855
* tree-ssa-loop-unswitch.c: Include tree-ssa-loop-manip.h.
(tree_unswitch_outer_loop): Iterate find_loop_guard as long as we
find guards to hoist. Do not update SSA form but rewrite virtuals
into loop closed SSA.
(find_loop_guard): Adjust to skip already hoisted guards. Do
not mark virtuals for renaming or update SSA form.
* gcc.dg/loop-unswitch-2.c: Adjust.
