re PR tree-optimization/39129 (The meaning of 'BB' in "too many BBs in loop")
PR tree-optimization/39129
* tree-vect-loop-manip.c (conservative_cost_threshold): Change the
printed message.
(vect_do_peeling_for_loop_bound): Use
LOOP_REQUIRES_VERSIONING_FOR_ALIGNMENT and
LOOP_REQUIRES_VERSIONING_FOR_ALIAS macros.
(vect_loop_versioning): Likewise.
(vect_create_cond_for_alias_checks): Fix indentation.
* tree-vectorizer.h (struct _loop_vec_info): Fix indentation of the
macros.
(LOOP_REQUIRES_VERSIONING_FOR_ALIGNMENT): Define.
(LOOP_REQUIRES_VERSIONING_FOR_ALIAS): Likewise.
* tree-vect-loop.c (vect_analyze_loop_form): Change "too many BBs" to
"control flow in loop".
(vect_estimate_min_profitable_iters): Use
LOOP_REQUIRES_VERSIONING_FOR_ALIGNMENT and
LOOP_REQUIRES_VERSIONING_FOR_ALIAS macros.
* tree-vect-data-refs.c (vect_enhance_data_refs_alignment): Likewise.
(vect_create_data_ref_ptr): Don't mention array dimension in printing.
* tree-vect-stmts.c (vectorizable_store): Replace the check that the
statement belongs to a group of strided accesses with the exact code
check.
(vectorizable_load): Likewise.
* tree-vect-slp.c (vect_analyze_slp_instance): Spell out "basic block".
(vect_slp_analyze_bb, vect_slp_transform_bb): Likewise.
