	* attribs.h (sorted_attr_string): Move machine independent
	functions for target clone support from the i386 port to common
	code.  Rename ix86_function_versions to common_function_versions.
	Rename make_name to make_unique_name.
	(common_function_versions): Likewise.
	(make_unique_name): Likewise.
	(make_dispatcher_decl): Likewise.
	(is_function_default_version): Likewise.
	* attribs.c (attr_strcmp): Likewise.
	(sorted_attr_string): Likewise.
	(common_function_versions): Likewise.
	(make_unique_name): Likewise.
	(make_dispatcher_decl): Likewise.
	(is_function_default_version): Likewise.
	* config/i386/i386.c (attr_strcmp): Likewise.
	(sorted_attr_string): Likewise.
	(ix86_function_versions): Likewise.
	(make_name): Likewise.
	(make_dispatcher_decl): Likewise.
	(is_function_default_version): Likewise.
	(TARGET_OPTION_FUNCTION_VERSIONS): Update target function hook.

	Back port from trunk

	* config/rs6000/rs6000.c (toplevel): Include attribs.h.
	(CLONE_*): New constants to define the processors we can generate
	code for with the target_clone attribute.
	(rs6000_clone_map): New array to identify which clone processors
	the current program is running on.
	(TARGET_COMPARE_VERSION_PRIORITY): Define to enable the
	target_clone attribute.
	(TARGET_GENERATE_VERSION_DISPATCHER_BODY): Likewise.
	(TARGET_GET_FUNCTION_VERSIONS_DISPATCHER): Likewise.
	(TARGET_OPTION_FUNCTION_VERSIONS): Likewise.
	(cpu_expand_builtin): Add support for target_clone attribute.
	(rs6000_valid_attribute_p): Allow "default" attribute.
	(get_decl_name): New debug function to simplify printing the
	current function name in debugging statements.
	(rs6000_clone_priority): New functions to support the target_clone
	attribute, and be able to generate code to switch between ISA 2.05
	through ISA 3.0 (power6 through power9).
	(rs6000_compare_version_priority): Likewise.
	(rs6000_get_function_versions_dispatcher): Likewise.
	(make_resolver_func): Likewise.
	(add_condition_to_bb): Likewise.
	(dispatch_function_versions): Likewise.
	(rs6000_generate_version_dispatcher_body): Likewise.
	(rs6000_can_inline_p): Call get_decl_name for debugging usage.
	(fusion_gpr_load_p): Fix a spacing issue.
	* doc/extend.texi (Common Function Attributes): Document that the
	PowerPC supports the target_clone attribute.
