AMD64 optimization on FreeBSD 5.4 i386 - FreeBSD

Hi, I have a AMD64 and use FreeBSD 5.4 i386. I have set CPUTYPE=k8 to optimize a little for my computer. I have seen they set march=athlon-mp when it compile something. Ok, I have see they is a difference between march=k8 and march=athlon-mp Have a idea ? Does I compile with march=k8 under cflags ? for example: CFLAGS=-O2 -march=k8 -pipe CXXFLAGS=$CFLAGS Well, what do you think ? could I optimize more than CPUTYPE=k8 ? ok see ya -- Vincent Bachelier <fr> Language : Francais / English Societ(e/y) : Solintech - http://www.solintech.fr - Serveurs linux Citation (fortune): we will invent new ...

    Default AMD64 optimization on FreeBSD 5.4 i386

    Hi, I have a AMD64 and use FreeBSD 5.4 i386.
    I have set CPUTYPE=k8 to optimize a little for my computer.
    I have seen they set march=athlon-mp when it compile something.

    Ok, I have see they is a difference between march=k8 and march=athlon-mp

    Have a idea ?
    Does I compile with march=k8 under cflags ?
    for example: CFLAGS=-O2 -march=k8 -pipe
    CXXFLAGS=$CFLAGS

    Well, what do you think ?
    could I optimize more than CPUTYPE=k8 ?
    ok see ya

    Why aren't you using the amd64 version of FreeBSD?
     

    I you were running amd64, you could use CPUTYPE=athlon64.
     

    Yes, download the ISO for amd64 and install it. :-)
     

    I think the CXXFLAGS setting is unnecessary, as this will happen by
    default.
     

    I think you should be running amd64. :-)
     

    Yes. See above. :-)

    Seriously, though, the amd64 version of FreeBSD is quite stable and
    usable, and would allow you to take full advantage of your machine's
    64-bit architecture. Why settle for less?

    Ok, I have found the solution

    CFLAGS += -march=k8

    and use pkgtools.conf for certain application that doesn't support it.
    gcc32 gcc33 fr-openoffice ...

    doesn't the nvidia driver works on amd64 version of freebsd ?

    ok see ya
