How's this?

        * mips-tdep.c (mips_gdbarch_init): Set size of long double
        to 128 bits for N32 and N64 ABIs.
        * mips-irix-tdep.c: Include "floatformat.h".
        (mips_irix_floatformat_always_valid): New function.
        (floatformat_mips_irix_long_double_big): New constant.
        (mips_irix_init_abi): Set the long double floatformat.

Tested on mips-irix. OK to apply?

Thanks,
