tree.def (TARGET_MEM_REF): Merge TMR_SYMBOL and TMR_BASE.
2010-09-03 Richard Guenther <rguenther@suse.de>
* tree.def (TARGET_MEM_REF): Merge TMR_SYMBOL and TMR_BASE.
Move TMR_OFFSET to second operand. Add TMR_INDEX2.
* tree.h (TMR_SYMBOL): Remove.
(TMR_BASE, TMR_OFFSET): Adjust.
(TMR_INDEX2): New.
* alias.c (ao_ref_from_mem): Use TMR_BASE.
* builtins.c (get_object_alignment): Merge TMR_BASE and
TMR_SYMBOL handling.
* cfgexpand.c (expand_debug_expr): Use TMR_BASE.
* gimple.c (get_base_address): Merge MEM_REF and TARGET_MEM_REF
handling. Also allow TARGET_MEM_REF as base address.
(walk_stmt_load_store_addr_ops): TMR_BASE is always non-NULL.
* gimplify.c (gimplify_expr): Gimplify TMR_BASE like MEM_REF
base. Gimplify TMR_INDEX2.
* tree-cfg.c (verify_types_in_gimple_reference): Adjust.
* tree-dfa.c (get_ref_base_and_extent): Likewise.
(get_addr_base_and_unit_offset): Likewise.
* tree-eh.c (tree_could_trap_p): Likewise.
* tree-pretty-print.c (dump_generic_node): Likewise.
* tree-ssa-address.c (tree_mem_ref_addr): Simplify. Handle
TMR_INDEX2.
(create_mem_ref_raw): Merge symbol and base. Move 2ndary
base to index2.
(get_address_description): Reconstruct addres description
from merged TMR_BASE and TMR_INDEX2.
(maybe_fold_tmr): Fold propagated addresses.
* tree-ssa-alias.c (indirect_ref_may_alias_decl_p): Merge
MEM_REF and TARGET_MEM_REF paths.
(indirect_refs_may_alias_p): Likewise.
* tree-ssa-live.c (mark_all_vars_used_1): Handle TMR_INDEX2
instead of TMR_SYMBOL.
* tree-ssa-operands.c (get_tmr_operands): Simplify.
* tree-ssa-pre.c (create_component_ref_by_pieces_1): Adjust
according to changes ...
* tree-ssa-sccvn.c (copy_reference_ops_from_ref): ... here.
Split TARGET_MEM_REF into two fields plus the base.
* tree.c (mem_ref_offset): Simplify.
* tree-ssa-loop-im.c (for_each_index): Handle TMR_INDEX2.
* tree-ssa-loop-ivopts.c (find_interesting_uses_address): Likewise.
Strip NOPs when folding MEM_REF addresses.
* tree-ssa-sink.c (is_hidden_global_store): Handle TARGET_MEM_REF.
* gimple-fold.c (maybe_fold_reference): Fold TARGET_MEM_REF here ...
(fold_gimple_assign): ... not here.
