* config/mips/tm-mips.h (FUNCTION_START_OFFSET, IN_SIGTRAMP,
	REGISTER_VIRTUAL_SIZE): Delete.
	(REGISTER_CONVERT_FROM_TYPE, REGISTER_CONVERT_TO_TYPE): Convert
	from macros to functions.

	* mips-tdep.c (mips_register_convert_from_type,
        mips_register_convert_to_type): New functions.
        (mips_gdbarch_init): Set up function_start_offset,
	register_virtual_size, pc_in_sigtramp.
