re PR tree-optimization/41881 (Complete unrolling (inner) versus vectorization of reduction)
PR tree-optimization/41881
* tree-vectorizer.h (struct _loop_vec_info): Add new field
reduction_chains along with a macro for its access.
* tree-vect-loop.c (new_loop_vec_info): Initialize
reduction chains.
(destroy_loop_vec_info): Free reduction chains.
(vect_analyze_loop_2): Return false if
vect_analyze_slp() returns false.
(vect_is_slp_reduction): New function.
(vect_is_simple_reduction_1): Call
vect_is_slp_reduction.
(vect_create_epilog_for_reduction): Support SLP
reduction chains.
* tree-vect-slp.c (vect_get_and_check_slp_defs): Allow
different definition types for reduction chains.
(vect_supported_load_permutation_p): Don't allow
permutations for reduction chains.
(vect_analyze_slp_instance): Support reduction chains.
(vect_analyze_slp): Try to build SLP instance from
reduction chains.
(vect_get_constant_vectors): Handle reduction chains.
(vect_schedule_slp_instance): Mark the first statement
of the reduction chain as reduction.
