re PR tree-optimization/35972 (load-PRE missed opportunities without SFTs)

2008-08-19  Richard Guenther  <rguenther@suse.de>

	PR tree-optimization/35972
	PR tree-optimization/23094
	* tree-ssa-sccvn.h (vn_reference_lookup_pieces): Add maywalk
	parameter.
	* tree-ssa-sccvn.c (copy_reference_ops_from_ref): Properly
	handle MISALIGNED_INDIRECT_REF.
	(get_ref_from_reference_ops): New helper.
	(vn_reference_lookup_pieces): Walk the use-def chain using the
	alias-oracle if requested.
	* tree-ssa-pre.c (phi_translate_1): Do reference lookup with
	walking the use-def chain.
	(compute_avail): But not here.
	(create_component_ref_by_pieces_1): Properly handle
	MISALIGNED_INDIRECT_REF.
	(do_regular_insertion): Handle fully redundant
	expressions after PHI-translation also for SSA_NAME values, not
	only constants.  Correctly use edoubleprime for that.

	* gcc.dg/tree-ssa/ssa-pre-19.c: New testcase.
	* gcc.dg/autopar/reduc-1.c: Move constant initialized arrays to
	global memory.
