2005-07-16  Danny Berlin <dberlin@dberlin.org>

	* Makefile.in: Added rules for ipa-pure-const.c, ipa-reference.c,
	ipa-reference.h, ipa-utils.c, ipa-utils.h, ipa-type-escape.c,
	ipa-type-escape.h, tree-promote-statics.c
	* ipa-pure-const.c, ipa-reference.c, ipa-reference.h, ipa-utils.c,
	ipa-utils.h, ipa-type-escape.c, ipa-type-escape.h,
	tree-promote-statics.c: new files.
	* alias.c: (nonlocal_mentioned_p_1, nonlocal_mentioned_p,
	nonlocal_referenced_p_1, nonlocal_referenced_p, nonlocal_set_p_1,
	int nonlocal_set_p, mark_constant_function): Deleted.
	(rest_of_handle_cfg): Removed call to mark_constant_function.
        (nonoverlapping_component_refs_p): Added calls to support
	type based aliasing.
        * tree-ssa-alias.c (may_alias_p,
	compute_flow_insensitive_aliasing): Ditto.
	* calls.c (flags_from_decl_or_type): Removed reference to
	cgraph_rtl_info.
	(flags_from_decl_or_type): Support ECF_POINTER_NO_CAPTURE attribute.
	* c-common.c (handle_pointer_no_capture_attribute): New function
	and added pointer_no_capture attribute.
      	* c-typeck.c (convert_arguments): Make builtins tolerant of having
	too many arguments.  This is necessary for Spec 2000.
	* cgraph.h (const_function, pure_function): Removed.
	* common.opt: Added "fipa-pure-const", "fipa-reference",
	"fipa-type-escape", and "ftree-promote-static".
	* opts.c: Ditto.
	* passes.c: Added ipa and tree-promote-statics passes.
	* timevar.def: Added TV_IPA_PURE_CONST, TV_IPA_REFERENCE,
	TV_IPA_TYPE_ESCAPE, and TV_PROMOTE_STATICS.
	* tree.h: Support ECF_POINTER_NO_CAPTURE attribute.
	* tree-dfa.c (referenced_var_lookup_if_exists): New function.
	* tree-flow.h: Added exposed sra calls and addition of
	reference_vars_info field for FUNCTION_DECLS.
	* tree-pass.h: Added passes.
	* tree-sra.c: (sra_init_cache): New function.
	(sra_insert_before, sra_insert_after) Made public.
	(type_can_be_decomposed_p): Renamed from type_can_be_decomposed_p
	and made public.
	* tree-ssa-alias.c (dump_alias_stats): Added stats for type based
	aliasing. (may_alias_p): Added code to use type escape analysis to
	improve alias sets.
	* tree-ssa-operands.c (add_call_clobber_ops): Added parameter and
	code to prune clobbers of static variables based on information
	produced in ipa-reference pass.  Changed call clobbering so that
	statics are not marked as clobbered if the call does not clobber
	them.

	    Kenneth Zadeck <zadeck@naturalbridge.com>

	* gcc.dg/tree-ssa/ssa-dce-2.c: Changed dg-options to run at -O2
	since pure const detection cannot run at -O1 in c compiler.
	* gcc.dg/tree-ssa/20030714-1.c Changed scanning patterns because we
	can now optimize this case properly.
	* gcc.dg/tree-ssa/sra-2.c: Changed to -O3 and removed xfail
	because we now pass.
	* gcc.dg/vect/vect-92.c: Removed out of bounds array access.
