* 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.
end-sanitize-r5900
