koakuma added a comment.

I have a little bit of question regarding aesthetics: In the text assembly language, if the destination of FP compare is not specified, then it is taken as %fcc0.
(that is, `fcmp<s|d|q> rs1, rs2` is encoded in the same way as `fcmp<s|d|q> %fcc0, rs1, rs2` in the binary machine language)
Currently LLVM prefers to emit the former form. Is it okay to leave it as-is, or should it be changed so it explicitly spells out the %fcc0 destination?
