for gcc/ChangeLog PR rtl-optimization/64164 * Makefile.in (OBJS): Drop tree-ssa-copyrename.o. * tree-ssa-copyrename.c: Removed. * opts.c (default_options_table): Drop -ftree-copyrename. Add -ftree-coalesce-vars. * passes.def: Drop all occurrences of pass_rename_ssa_copies. * common.opt (ftree-copyrename): Ignore. (ftree-coalesce-inlined-vars): Likewise. * doc/invoke.texi: Remove the ignored options above. * gimple-expr.h (gimple_can_coalesce_p): Move declaration * tree-ssa-coalesce.h: ... here. * tree-ssa-uncprop.c: Include tree-ssa-coalesce.h and other headers required by it. * gimple-expr.c (gimple_can_coalesce_p): Allow coalescing across variables when flag_tree_coalesce_vars. Check register use and promoted modes to allow coalescing. Moved to tree-ssa-coalesce.c. * tree-ssa-live.c (struct tree_int_map_hasher): Move along with its member functions to tree-ssa-coalesce.c. (var_map_base_init): Likewise. Renamed to compute_samebase_partition_bases. (partition_view_normal): Drop want_bases parameter. (partition_view_bitmap): Likewise. * tree-ssa-live.h: Adjust declarations. * tree-ssa-coalesce.c: Include explow.h. (build_ssa_conflict_graph): Process PARM_ and RESULT_DECLs's default defs at the entry point. (dump_part_var_map): New. (compute_optimized_partition_bases): New, called by... (coalesce_ssa_name): ... when flag_tree_coalesce_vars, instead of compute_samebase_partition_bases. Adjust. * alias.c (nonoverlapping_memrefs_p): Disregard gimple-regs. * cfgexpand.c (leader_merge): New. (get_rtl_for_parm_ssa_default_def): New. (set_rtl): Merge exprs and attrs, even for MEMs and non-SSA vars. Update DECL_RTL for PARM_DECLs and RESULT_DECLs too. (expand_one_stack_var_at): Handle anonymous SSA_NAMEs. Drop redundant MEM attr setting. (expand_one_stack_var_1): Handle anonymous SSA_NAMEs. Renamed from... (expand_one_stack_var): ... this. New wrapper to check and skip already expanded SSA partitions. (record_alignment_for_reg_var): New, factored out of... (expand_one_var): ... this. (expand_one_ssa_partition): New. (adjust_one_expanded_partition_var): New. (expand_one_register_var): Check and skip already expanded SSA partitions. (expand_used_vars): Don't create DECLs for anonymous SSA names. Expand all SSA partitions, then adjust all SSA names. (pass::execute): Replace the loops that set SA.partition_to_pseudo from partition leaders and cleared DECL_RTL for multi-location variables, and that which used to rename vars and set attrs, with one that clears DECL_RTL and checks that PARMs and RESULTs default_defs match DECL_RTL. * cfgexpand.h (get_rtl_for_parm_ssa_default_def): Declare. * emit-rtl.c (set_reg_attrs_for_parm): Handle NULL decl. * explow.c (promote_ssa_mode): New. * explow.h (promote_ssa_mode): Declare. * expr.c (expand_expr_real_1): Handle anonymous SSA_NAMEs. * function.c: Include cfgexpand.h. (use_register_for_decl): Handle SSA_NAMEs, anonymous or not. (use_register_for_parm_decl): Wrapper for the above to special-case the result_ptr. (rtl_for_parm): Ditto for get_rtl_for_parm_ssa_default_def. (maybe_reset_rtl_for_parm): Reset DECL_RTL of parms with multiple locations. (assign_parm_adjust_stack_rtl): Add all and parm arguments, for rtl_for_parm. For SSA-assigned parms, zero stack_parm. (assign_parm_setup_block): Prefer SSA-assigned location. (assign_parm_setup_reg): Likewise. Use entry_parm for equiv if stack_parm is NULL. (assign_parm_setup_stack): Prefer SSA-assigned location. (assign_parms): Maybe reset DECL_RTL of params. Adjust stack rtl before testing for pointer bounds. Special-case result_ptr. (expand_function_start): Maybe reset DECL_RTL of result. Prefer SSA-assigned location for result and static chain. Factor out DECL_RESULT and SET_DECL_RTL. * tree-outof-ssa.c (insert_value_copy_on_edge): Handle anonymous SSA names. Use promote_ssa_mode. (get_temp_reg): Likewise. (remove_ssa_form): Adjust. * var-tracking.c (dataflow_set_clear_at_call): Take call_insn and get its reg_usage for reg invalidation. (compute_bb_dataflow): Pass it insn. (emit_notes_in_bb): Likewise. * tree-ssa-loop-niter.c (loop_exits_before_overflow): Don't fail assert on conversion between unsigned types. for gcc/testsuite/ChangeLog * gcc.dg/guality/pr54200.c: Add -fno-tree-coalesce-vars. * gcc.dg/ssp-1.c: Make counter a register. * gcc.dg/ssp-2.c: Likewise. * gcc.dg/torture/parm-coalesce.c: New.

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
