    SUSE C Compiler Question

    Apologies in advance but I am a Linux newbie.....

    Will SuSE-9 C programs compiled with the option -M31 be able to execute on 64 bit versions of SuSE-10 without a re-compile?

    Alrighty. So I can't find any "-M31" option in the gcc man pages. I assume it specifies 32-bit registers?

    If this is the case, then yes. 64-bit chips can run 32-bit programs, just they will not take full advantage of the 64-bit chip.
