2017-11-29 Richard Biener <rguenther@suse.de>
PR tree-optimization/83202
* tree-vect-slp.c (scalar_stmts_set_t): New typedef.
(bst_fail): Use it.
(vect_analyze_slp_cost_1): Add visited set, do not account SLP
nodes vectorized to the same stmts multiple times.
(vect_analyze_slp_cost): Allocate a visited set and pass it down.
(vect_analyze_slp_instance): Adjust.
(scalar_stmts_to_slp_tree_map_t): New typedef.
(vect_schedule_slp_instance): Add a map recording the SLP node
representing the vectorized stmts for a set of scalar stmts.
Avoid code-generating redundancies.
(vect_schedule_slp): Allocate map and pass it down.
* gcc.dg/vect/costmodel/x86_64/costmodel-pr83202.c: New testcase.
