re PR tree-optimization/60510 (SLP blocks loop vectorization (with reduction))
2017-07-03 Richard Biener <rguenther@suse.de>
PR tree-optimization/60510
* tree-vect-loop.c (vect_create_epilog_for_reduction): Pass in
the scalar reduction PHI and use it.
(vectorizable_reduction): Properly guard the single_defuse_cycle
path for non-SLP reduction chains where we cannot use it.
Rework reduc_def/index and vector type deduction. Rework
vector operand gathering during reduction op code-gen.
* tree-vect-slp.c (vect_analyze_slp): For failed SLP reduction
chains dissolve the chain and leave it to non-SLP reduction
handling.
* gfortran.dg/vect/pr60510.f: New testcase.
