	* config/darwin-protos.h (machopic_function_base_name): Delete.
	(machopic_function_base_sym): Likewise.
	(machopic_gen_offset): Declare.
	* config/darwin.h (MACHOPIC_FUNCTION_BASE_NAME): New macro.
	(ASM_OUTPUT_LABELREF): Use it instead of a hard-coded string constant.
	* config/darwin.c (machopic_function_base_name): Delete.
	(machopic_function_base_sym): Likewise.
	(gen_pic_offset): Rename to...
	(machopic_gen_offset): ...this and remove the pic_base argument.
	Instead use MACHO_DYNAMIC_NO_PIC_P to decide whether a PIC offset
	is needed.  Create an UNSPEC_MACHOPIC_OFFSET if so, and set
	crtl->uses_pic_offset_table.
	(machopic_indirect_data_reference): Use new machopic_gen_offset
	interface.
	(machopic_legitimize_pic_address): Likewise.
	(machopic_operand_p): Check for UNSPEC_MACHOPIC_OFFSET.

	* config/i386/darwin.h (GOT_SYMBOL_NAME): Use
	MACHOPIC_FUNCTION_BASE_NAME instead of machopic_function_base_name.
	* config/i386/i386.c (output_set_got): Likewise.
	(darwin_local_data_pic): Check for an UNSPEC_MACHOPIC_OFFSET

	(ix86_delegitimize_address): Expect darwin_local_data_pic to
	match an UNSPEC rather than a MINUS.
	* config/i386/i386.md (UNSPEC_MACHOPIC_OFFSET): Define.
	(builtin_setjmp_receiver): Use machopic_gen_offset.
	* config/i386/predicates.md (pic_symbolic_operand): Handle
	UNSPEC_MACHOPIC_OFFSET.

	* config/rs6000/rs6000.c (rs6000_legitimize_reload_address):
	Use machopic_gen_offset and machopic_operand_p.
