* config/mips/tm-mips.h (MAKE_MSYMBOL_SPECIAL): Force MIPS16

	addresses to be odd.
	(MIPS_FPU_SINGLE_REGSIZE, MIPS_FPU_DOUBLE_REGSIZE): Define.
	* mips-tdep.c (mips_extract_return_value): Doubles aren't
	returned in FP0 if FP registers are single-precision only.
start-sanitize-r5900
	* config/mips/tm-r5900.h (MIPS_LAST_FP_ARG_REGNUM): Redefine
	to disable use of FP registers for function arguments.
