Some refactoring might make the flow easier to follow but I've refrained from doing that with this patch. I've kept some fixes in reduction epilogue generation from the earlier attempt fixing this PR. PR tree-optimization/113373 * tree-vect-loop-manip.cc (slpeel_tree_duplicate_loop_to_edge_cfg): Create LC PHIs in the exit blocks where necessary. * tree-vect-loop.cc (vectorizable_live_operation): Do not try to handle missing LC PHIs. (find_connected_edge): Remove. (vect_create_epilog_for_reduction): Cleanup use of auto_vec. * gcc.dg/vect/vect-early-break_104-pr113373.c: New testcase.
