2019-11-18  Richard Biener  <rguenther@suse.de>

	PR tree-optimization/92516
	* tree-vect-slp.c (vect_analyze_slp_instance): Add bst_map
	argument, hoist bst_map creation/destruction to ...
	(vect_analyze_slp): ... here, forming a true graph with
	SLP instances being the entries.
	(vect_detect_hybrid_slp_stmts): Remove wrapper.
	(vect_detect_hybrid_slp): Use one visited set for all
	graph entries.
	(vect_slp_analyze_node_operations): Simplify visited/lvisited
	to hash-sets of slp_tree.
	(vect_slp_analyze_operations): Likewise.
	(vect_bb_slp_scalar_cost): Remove wrapper.
	(vect_bb_vectorization_profitable_p): Use one visited set for
	all graph entries.
	(vect_schedule_slp_instance): Elide bst_map use.
	(vect_schedule_slp): Likewise.

	* g++.dg/vect/slp-pr92516.cc: New testcase.

2019-11-18  Richard Biener  <rguenther@suse.de>

	* tree-vect-slp.c (vect_analyze_slp_instance): When a CTOR
	was vectorized with just external refs fail.

	* gcc.dg/vect/vect-ctor-1.c: New testcase.
