Genetic Algorithms and Compiler Optimizations

Posted by michael on from the when-it-absolutely-positively-has-to-run-overnight dept.

mfago writes "Scott Robert Ladd has written an enlightening article and accompanying software package that utilizes genetic algorithms to optimize the optimization flags fed to a compiler. Those who have tried to squeeze the last drop of performance from a code know that it can be very difficult to determine the set of optimization flags beyond -O3 (with gcc for example) that yields the best performance. Lots of background links included in the article."

    Troll.

    A trivial "puts("hello world")" application with GCC 3.2.3 in GNU/Linux is a mere 2984 bytes.

    Maybe you're

    a)an idiot

    b)ignorant as to how GCC works

    c)a troll

    d) all of the above.

  6. It has come to my attention that you completely in by Anonymous Coward · · Score: -1, Troll

    It has come to my attention that you completely inhale the shit out of goatse's ass. Read on for more about this fascinating topic.

    The world went into shock a few weeks ago when goatse.info reported the results of a study which concluded that inhaling shit is a very dangerous pastime, one that no one is advised to take up. Eventually, everyone adapted to the new state of affairs and began inhaling other things. Almost everyone, that is. But not you! According to my records, you still inhale shit!

    Why?! What the fuck is wrong with you?!

    You moron, you idiot, you imbecile, you gay nigger ! Arg! You make me so fucking sick! FUCK YOU FUCK YOU FUCK YOU FUCK YOU FUCK YOU FUCK YOU FUCK YOU FUCK YOU FUCK YOU FUCK YOU FUCK YOU FUCK YOU FUCK YOU FUCK YOU FUCK YOU FUCK YOU FUCK YOU FUCK YOU.

    This is a new low. Next we'll see papers
    on using genetic algorithms to find the best
    channel on TV.

    What would be interesting is a genetic system
    to select meso-scale optimizations in a
    compile back-end, for example.
