Anyway, my objection to using ``ia64_ext'' for the 82-bit register
type stems from the fact that this name would probably be more
appropriate for the 80-bit double-extended type. Especially since
this is the convention already used for x86. How 'bout this instead?

ia64_ext - 80-bit double-extended
ia64_reg - 82-bit fp register
ia64_quad - 128-bit quad-precision

I was going to propose exactly the same :-). FYI Andrew, the ia64_ext
type is stored in 10 bytes of memory, the ia64_reg type is stored in
16 bytes of memory and ia64_quad is also stored in 16 bytes of memory.
It seems that ia64_ext would be identical to i387_ext, so we could
simply

#define floatformat_ia64_ext floatformat_i387_ext

in floatformat.h.
