Check for non-zero denorm in __adddf3. Need to check both the upper and
lower 32-bit chunks of a 64-bit float for a non-zero value when
checking to see if the value is -0.
Fix __addsf3 when the sum exponent is exactly 0xff to ensure that
produces infinity and not nan.
Handle converting NaN/inf values between formats.
Handle underflow and overflow when truncating.
Write a replacement for __fixxfsi so that it does not raise extra
exceptions during an extra conversion from long double to double.

I pushed this to the trunk after fixing a few minor whitespace nits.
You didn't mention the divdf change, but I'll assume that was just an
oversight.
I'm largely trusting your reputation on the fpgnulib changes. I won't
claim to know that code at all. The assembly bits were simple enough
that I could make out what you were doing relatively easily.
Thanks again,
Jeff
