You're just plain wrong. :P x86_64 is the generic name for amd64, emt64, and x64 (see below) so that is correct for the CHOST setting for that architecture. Chips using that architecture are also generally happy running as a x86 CHOST. For Itanium, the correct CHOST is (IIRC) ia64, and I'm not sure how well Gentoo supports it. > EM64T should always use nocona in the CFLAGS for 64bit. EMT64 and AMD64 are the same technology, just different marketing names. X64 is another name you'll see is some of Sun's literature. In any case, the -march setting is CPU specific, if your CPU isn't specificly mentioned as supported under a -march setting, you could produce broken executables. -- "If there's one thing we've established over the years, it's that the vast majority of our users don't have the slightest clue what's best for them in terms of package stability." -- Gentoo Developer Ciaran McCreesh
