re PR tree-optimization/56270 (loop over array of struct float causes compiler error: segmentation fault)

2013-04-19  Richard Biener  <rguenther@suse.de>

	* tree-vectorizer.h (struct _slp_instance): Move load_permutation
	member ...
	(struct _slp_tree): ... here.  Make it a vector of unsigned ints.
	(SLP_INSTANCE_LOAD_PERMUTATION): Remove.
	(SLP_TREE_LOAD_PERMUTATION): Add.
	(vect_transform_slp_perm_load): Adjust prototype.
	* tree-vect-slp.c (vect_free_slp_tree): Adjust.
	(vect_free_slp_instance): Likewise.
	(vect_create_new_slp_node): Likewise.
	(vect_supported_slp_permutation_p): Remove.
	(vect_slp_rearrange_stmts): Adjust.
	(vect_supported_load_permutation_p): Likewise.  Inline
	vect_supported_slp_permutation_p here.
	(vect_analyze_slp_instance): Compute load permutations per
	slp node instead of per instance.
	(vect_get_slp_defs): Adjust.
	(vect_transform_slp_perm_load): Likewise.
	(vect_schedule_slp_instance): Remove redundant code.
	(vect_schedule_slp): Remove hack for PR56270, add it ...
	* tree-vect-stmts.c (vectorizable_load): ... here, do not
	CSE loads for SLP.  Adjust.
