tree-vectorizer.h (_stmt_vec_info::v_reduc_type): Remove.
2019-10-08 Richard Biener <rguenther@suse.de>
* tree-vectorizer.h (_stmt_vec_info::v_reduc_type): Remove.
(_stmt_vec_info::is_reduc_info): Add.
(STMT_VINFO_VEC_REDUCTION_TYPE): Remove.
(vectorizable_condition): Remove.
(vectorizable_shift): Likewise.
(vectorizable_reduction): Adjust.
(info_for_reduction): New.
* tree-vect-loop.c (vect_force_simple_reduction): Fold into...
(vect_analyze_scalar_cycles_1): ... here.
(vect_analyze_loop_operations): Adjust.
(needs_fold_left_reduction_p): Simplify for single caller.
(vect_is_simple_reduction): Likewise. Remove stmt restriction
for nested cycles not part of double reductions.
(vect_model_reduction_cost): Pass in the reduction type.
(info_for_reduction): New function.
(vect_create_epilog_for_reduction): Use it, access reduction
meta off the stmt info it returns. Use STMT_VINFO_REDUC_TYPE
instead of STMT_VINFO_VEC_REDUCTION_TYPE.
(vectorize_fold_left_reduction): Remove pointless assert.
(vectorizable_reduction): Analyze the full reduction when
visiting the outermost PHI. Simplify. Use STMT_VINFO_REDUC_TYPE
instead of STMT_VINFO_VEC_REDUCTION_TYPE. Direct reduction
stmt code-generation to vectorizable_* in most cases. Verify
code-generation only for cases handled by
vect_transform_reductuon.
(vect_transform_reduction): Use info_for_reduction to get at
reduction meta. Simplify.
(vect_transform_cycle_phi): Likewise.
(vectorizable_live_operation): Likewise.
* tree-vect-patterns.c (vect_reassociating_reduction_p): Look
at the PHI node for STMT_VINFO_REDUC_TYPE.
* tree-vect-slp.c (vect_schedule_slp_instance): Remove no
longer necessary code.
* tree-vect-stmts.c (vectorizable_shift): Make static again.
(vectorizable_condition): Likewise. Get at reduction related
info via info_for_reduction.
(vect_analyze_stmt): Adjust.
(vect_transform_stmt): Likewise.
* tree-vectorizer.c (vec_info::new_stmt_vec_info): Initialize
STMT_VINFO_REDUC_TYPE instead of STMT_VINFO_VEC_REDUCTION_TYPE.
* gcc.dg/vect/pr65947-1.c: Adjust.
* gcc.dg/vect/pr65947-13.c: Likewise.
* gcc.dg/vect/pr65947-14.c: Likewise.
* gcc.dg/vect/pr65947-4.c: Likewise.
* gcc.dg/vect/pr80631-1.c: Likewise.
* gcc.dg/vect/pr80631-2.c: Likewise.
