[llvm-dev] X86_FP80 in APFloat

Hi all,

I want to extract the actual value of an X86_FP80 APFloat Constant. Is
there any API with which I can get the value of mantissa and exponent?

I tried ConvertToHexString, but for x86_fp80 0xK8FFFC000000000000000, it
just returns nan, instead I want the actual byte information.

There are APIs like convertToDouble and convertToFloat for APFloat single
and double precision, I am looking for something similar for extended
