tree-vectorizer.h (check_reduction_path): Declare.
2017-12-04 Richard Biener <rguenther@suse.de>
* tree-vectorizer.h (check_reduction_path): Declare.
* tree-vect-loop.c (check_reduction_path): New function, split out
from ...
(vect_is_simple_reduction): ... here.
* gimple-loop-interchange.cc: Include tree-vectorizer.h.
(loop_cand::analyze_iloop_reduction_var): Use single_imm_use.
Properly check for a supported reduction operation and a
valid expression if the reduction covers multiple stmts.
(prepare_perfect_loop_nest): Simpify allocation.
(pass_linterchange::execute): Likewise.
* gcc.dg/tree-ssa/loop-interchange-1.c: Add fast-math flags.
* gcc.dg/tree-ssa/loop-interchange-1b.c: New test variant.
* gcc.dg/tree-ssa/loop-interchange-4.c: XFAIL.
