re PR tree-optimization/37021 (Fortran Complex reduction / multiplication not vectorized)
2015-05-12 Richard Biener <rguenther@suse.de>
PR tree-optimization/37021
* tree-vectorizer.h (struct _slp_tree): Add two_operators flag.
(SLP_TREE_TWO_OPERATORS): New define.
* tree-vect-slp.c (vect_create_new_slp_node): Initialize
SLP_TREE_TWO_OPERATORS.
(vect_build_slp_tree_1): Allow two mixing plus/minus in an
SLP node.
(vect_build_slp_tree): Adjust.
(vect_analyze_slp_cost_1): Likewise.
(vect_schedule_slp_instance): Vectorize mixing plus/minus by
emitting two vector stmts and mixing the results.
* gcc.target/i386/vect-addsub.c: New testcase.
