Re: 80 bit floating point support for i960.



> The patch permits 80-bit floating point numbers for i960.

I think it may be impractical to select this at run time (i.e. not worth
the amount of effort it would require).  The size of long double is a
compile time constant macro, and the definition of a REAL_VALUE_TYPE
depends on that size.  You can build the compiler one way or the other but
not both ways at once.

To permit building either a 96-bit or 128-bit long double version for i960
you would need to check the size in i960_output_long_double.
