Delay SLP instance loads gathering
This delays filling SLP_INSTANCE_LOADS.
2020-11-16 Richard Biener <rguenther@suse.de>
* tree-vectorizer.h (vect_gather_slp_loads): Declare.
* tree-vect-loop.c (vect_analyze_loop_2): Call
vect_gather_slp_loads.
* tree-vect-slp.c (vect_build_slp_instance): Do not gather
SLP loads here.
(vect_gather_slp_loads): Remove wrapper, new function.
(vect_slp_analyze_bb_1): Call it.
