While you're right about sparc64, amd64 is a little different because you get more registers when you're running in 64bit mode. I think there's some other advantages too that actually make up for the fact that the pointers and whatnot are larger. > But that's not a reason to delay AMD64 from being in Sid IMHO.

Sure, biarch is good, will be useful on amd64 as well as other things when it eventually happens, but let's get a pure amd64 into the archive since it's ready to go now. Stephen
