tree-ssa-sccvn.c (copy_reference_ops_from_ref): Record TMR_ORIGINAL.
2009-05-22 Richard Guenther <rguenther@suse.de>
* tree-ssa-sccvn.c (copy_reference_ops_from_ref): Record
TMR_ORIGINAL. Always either record TMR_SYMBOL or TMR_BASE.
* tree-ssa-pre.c (create_component_ref_by_pieces_1): Handle
TARGET_MEM_REF.
(create_expression_by_pieces): Only convert if necessary.
* gimplify.c (gimplify_expr): Handle TARGET_MEM_REF.
* tree-ssa-loop-im.c (gen_lsm_tmp_name): Handle INTEGER_CST.
