Remove SLP_INSTANCE_GROUP_SIZE
This removes the SLP_INSTANCE_GROUP_SIZE member since the number of
lanes throughout a SLP subgraph is not necessarily constant.
2020-05-13 Richard Biener <rguenther@suse.de>
* tree-vectorizer.h (SLP_INSTANCE_GROUP_SIZE): Remove.
(_slp_instance::group_size): Likewise.
* tree-vect-loop.c (vectorizable_reduction): The group size
is the number of lanes in the node.
* tree-vect-slp.c (vect_attempt_slp_rearrange_stmts): Likewise.
(vect_analyze_slp_instance): Do not set SLP_INSTANCE_GROUP_SIZE,
verify it matches the instance trees number of lanes.
(vect_slp_analyze_node_operations_1): Use the numer of lanes
in the node as group size.
(vect_bb_vectorization_profitable_p): Use the instance root
number of lanes for the size of life.
(vect_schedule_slp_instance): Use the number of lanes as
group_size.
* tree-vect-stmts.c (vectorizable_load): Remove SLP instance
parameter. Use the number of lanes of the load for the group
size in the gap adjustment code.
(vect_analyze_stmt): Adjust.
(vect_transform_stmt): Likewise.
