2019-10-29 Richard Biener <rguenther@suse.de>
PR tree-optimization/65930
* tree-vect-loop.c (check_reduction_path): Relax single-use
check allowing out-of-loop uses.
(vect_is_simple_reduction): SLP reduction chains cannot have
intermediate stmts used outside of the loop.
(vect_create_epilog_for_reduction): The adjustment might need
to be converted.
(vectorizable_reduction): Annotate live stmts of the reduction
chain with STMT_VINFO_REDUC_DEF.
* tree-vect-stms.c (process_use): Remove no longer true asserts.
* gcc.dg/vect/pr65930-1.c: New testcase.
