You're just plain wrong. :P |

x86_64 is the generic name for amd64, emt64, and x64 (see below) so that is |
11 |
correct for the CHOST setting for that architecture. Chips using that |
12 |
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 |
15 |
Gentoo supports it. |

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, |
21 |
the -march setting is CPU specific, if your CPU isn't specificly mentioned |
22 |
as supported under a -march setting, you could produce broken executables. |
