	* ipa-pure-const.c (state_from_flags, local_pure_const): Use
	current_function_name instead of lang_hooks.decl_printable_name.

	* function.h (fndecl_name): New prototype.
	* function.c (fndecl_name): New function.
	* vecir.h (cgraph_node_p): New standard IR VEC type.
	* trans-mem.c (cgraph_node_p): No need anymore to define it here.
	* ipa-utils.h (ipa_get_nodes_in_cycle): New prototype.
	* ipa-utils.c (ipa_get_nodes_in_cycle): New function.
	* ipa-reference.c: Don't include langhooks.h, and certainly not twice.
	Fix many formatting issues (long lines, short lines, spacing, etc.).
	(get_static_name): Use fndecl_name.
	(dump_static_vars_set_to_file): New function split out from propagate.
	(union_static_var_sets): New function, union two sets and collapse
	to all_module_statics as quickly as possible.
	(intersect_static_var_sets): New function, similar to above.
	(copy_static_var_set): Renamed from copy_global_bitmap and rewritten
	to allocate a copy on the same bitmap_obstack as the source set.
	(propagate_bits): Simplify, and clarify by using union_static_var_sets.
	(generate_summary): Remove bm_temp.  Print UID of promotable globals.
	(read_write_all_from_decl): Use pass-by-reference, bless C++.
	(get_read_write_all_from_node): New function, split out from propagate.
	(propagate): Simplify and clarify with helper functions.  Use
	ipa_get_nodes_in_cycle to walk all nodes in a reduced node.
	(ipa_reference_read_optimization_summary): Use fndecl_name instead of
	lang_hooks.decl_printable_name.

	* rtl.h (print_rtl_single_with_indent): New prototype.
	* print-rtl.c (print_rtl_single_with_indent): New function.
	* cfghooks.h (empty_block_p, split_block_before_cond_jump): New hooks.
	* cfghooks.c (empty_block_p, split_block_before_cond_jump): Implement.
	* cfgrtl.c (rtl_block_empty_p, rtl_split_block_before_cond_jump):
	Implement RTL specific hooks.
	(rtl_cfg_hooks, cfg_layout_rtl_cfg_hooks): Register the new hooks.
	* tree-cfg.c (gimple_empty_block_p,
	gimple_split_block_before_cond_jump): Implement GIMPLE specific hooks.
	(gimple_cfg_hooks): Register the new hooks.
	* tree-ssa-phiopt.c (empty_block_p): Remove in favor of new hook.
