--- Comment #5 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
So mips64-elf uses long double as 64bit and supports TImode (128bit integer)
but MAX_FIXED_MODE_SIZE is incorrectly defined as:
#define MAX_FIXED_MODE_SIZE MIPS_LONG_DOUBLE_TYPE_SIZE

I think it should be:
#define MAX_FIXED_MODE_SIZE (MAX (GET_MODE_BITSIZE (TARGET_64BIT ? TImode :
DImode), MIPS_LONG_DOUBLE_TYPE_SIZE))


And that fixes the ICE.
