https://reviews.llvm.org/D28926 provides perfectly clear definitions of what those functions are supposed to return; if something is wrong, just fix it (or file a bug). From your description, it sounds like we need to split "SignBitOnly" into "NegZeroSignBitSignificant" and "NanSignBitSignificant"?
