    http://cs.nmu.edu/~benchmark/ has an interesting little graph
    of LMBench results vs. Linux kernel version, all done with the
    same compiler.

    Has anyone seen a similar graph showing LMBench results vs. gcc version,
    all done with the same Linux kernel?
    And does everyone agree that's a meaningful way to compare the
    performance of code generated by different compilers?

    I happen to have a number of versions of gcc handy, and was
    considering making such a graph, but was hoping somebody
    else had already done it.

    (There seems to be large variations in successive runs of LMBench
    when I try it, so it may take me a bit of work to get repeatable
    results.)

    Thanks,
    Dan
