tree-optimization/114068 - missed virtual LC PHI after vect peeling
When we choose the IV exit to be one leading to no virtual use we
fail to have a virtual LC PHI even though we need it for the epilog
entry. The following makes sure to create it so that later updating
works.
PR tree-optimization/114068
* tree-vect-loop-manip.cc (get_live_virtual_operand_on_edge):
New function.
(slpeel_tree_duplicate_loop_to_edge_cfg): Add a virtual LC PHI
on the main exit if needed. Remove band-aid for the case
it was missing.
* gcc.dg/vect/vect-early-break_118-pr114068.c: New testcase.
* gcc.dg/vect/vect-early-break_119-pr114068.c: Likewise.
