    Athlon optimised compilation scripts
    Posted on Monday, July 23 @ 13:55:05 BST

    AMD
    Not that I condone the
    calls
    for Debian to maintain a separate tree for i586/i686
    packages, but for those who believe religiously in the powers of -mcpu/-march
    (ie. processor-specific optimisations), they will now be happy to know that they
    can now easily practice their religion in the privacy of their own box
    away from the prying eyes of bigotted trolls! Junichi Uekawa has just annouced
    the release of the AMD counterpart of Adrian Bunk's
    pentium-builder
    -- gcc3.0-athlon-builder at deb
    http://people.debian.org/~dancer/athlon-builder/ ./. The
    former of the two is already included stable and unstable with the latest
    version of it at
    http://osiris.978.org/~alex/pentium-builder/

    These two
    respective packages replace gcc, cc, and g++ with scripts that will
    build processor-optimised code. To take advantage of this
    automatically whenever you build packages using debhelper/apt-get, add
    either export DEBIAN_BUILDARCH=pentium or export
    DEBIAN_BUILDARCH=athlon
    to your .bashrc first and relogin before
    you begin building packages with forced optimisations.

    PS: Don't forget that compiling packages in this manner will make them
    incompatible with machines containing a different type of processor.

    This isn't that great. All the time wasted downloading, setting up, and compiling special packages will take a while to make up through optimizations. What we need is precompiled binaries optimized for specific processors or some automatic runtime optimization.

    After witnessing the performance improvement of pgcc on my old pentium based system I would really love to see more options to optimize code for my new Athlon. I was told that athlonlinux.org was a site detailing how to get more out of the Athlon, but all links to it appear to be dead. Does anyone know what happen to this site?

    I do like the idea behind athlon-builder and hope that more projects of this nature appear in the future.
