re PR tree-optimization/69168 (ICE in vect_analyze_loop_2, at tree-vect-loop.c:2182)
2016-01-12 Richard Biener <rguenther@suse.de>
PR tree-optimization/69168
* tree-vect-loop.c (vect_analyze_loop_2): Reset both main and
pattern stmt SLP type.
* tree-vect-slp.c (vect_detect_hybrid_slp_stmts): Patterns may
end up unused so cope with that case.
* gcc.dg/torture/pr69168.c: New testcase.
