Makefile.in: Added rules for ipa-pure-const.c... 2005-07-16 Danny Berlin <dberlin@dberlin.org> Kenneth Zadeck <zadeck@naturalbridge.com> * 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. 2005-07-16 Danny Berlin <dberlin@dberlin.org> 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.
