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.

(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.

(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.
