tree.c (init_ttree): Add STRUCT_FIELD_TAG handling.
2006-02-15 Daniel Berlin <dberlin@dberlin.org>
* tree.c (init_ttree): Add STRUCT_FIELD_TAG handling.
(tree_code_size): Ditto.
* tree.h (struct tree_memory_tag): Remove parent_var.
(struct tree_struct_field_tag): New.
(SFT_OFFSET): New.
(SFT_SIZE): New.
(union tree_node): Add sft member.
* tree-ssa-alias.c (get_tmt_for): Don't handle TYPE_READONLY
specially here.
(create_sft): Add size and offset argument, set SFT_OFFSET and
SFT_SIZE.
(create_overlap_variables_for): Update for SFT_OFFSET/SFT_SIZE.
* treestruct.def: Add TS_STRUCT_FIELD_TAG.
* tree-flow-inline.h (get_subvar_at): Update for
SFT_OFFSET/SFT_SIZE.
(var_can_have_subvars): Ditto.
(overlap_subvar): Ditto.
* print-tree.c (print_node): Print out interesting things for
SFT's.
* tree-flow.h (struct subvar): Remove offset and size members.
* tree-ssa-operands.c (get_expr_operands): Update for
get_indirect_ref_operands changes.
(get_indirect_ref_operands): Call add_virtual_operand instead of
add_stmt_operand. Only recurse on base var if requested.
(access_can_touch_variable): New function.
(add_stmt_operand): Split virtual operand handling into ...
(add_virtual_operand): Here. Add offset, size, and for_clobber
arguments. Prune alias sets.
(add_call_clobber_ops): Call add_virtual_operand.
