we would still have the other arches to do ie power,arm etc ,to make it unconditional addsub needs to allocate some tmp space ,I suppose we could split the addsub it to various overlap cases this may be possible , but for sumdiff I dont think it is > Is there a reason to not have an assembly optimised version for core2? > I havent found one for core2 or sandybridge which is faster than a separate add and sub > Bill. > > -- You received this message because you are subscribed to the Google Groups "mpir-devel" group.
