Can you name the assemblers which support this extension? Porting
of assembly code is nice, but very low priority. For this particular extension,
I think assembly code should be changed according to IA32/Intel64 SDM.

BTW, I have some MASM assembly codes I'd like to assemble with gas.

When I look at  fcomip and fucomip in assembly code, I have to guess
what they are.
