re PR tree-optimization/87873 (ICE: verify_gimple failed (error: incompatible types in PHI argument 0))
2018-11-05 Richard Biener <rguenther@suse.de>
PR tree-optimization/87873
* tree-ssa-loop-manip.h (split_loop_exit_edge): Add copy_constants_p
argument.
* tree-ssa-loop-manip.c (split_loop_exit_edge): Likewise.
* tree-vect-loop.c (vect_transform_loop): When splitting the
loop exit also create forwarder PHIs for constants.
* tree-vect-loop-manip.c (slpeel_duplicate_current_defs_from_edges):
Handle constant to_arg, add extra checking we match up the correct
PHIs.
* gcc.dg/pr87873.c: New testcase.
