The doubledouble type is available for PowerPC. In fact, I try to use this for my PowerPC64 port of LDC. The partial support here is a bit annoying but I did not find the time to implement the missing functions myself.It is "native" in the sense that it is a supported type by gcc and xlc.
Doesn't SSE2 effectively operate on double doubles too with instructions like addpd (and others *pd)?
