CC=gcc CFLAGS="-O4 -mcpu=v8"; export CC CFLAGS There are others as well. Also many times when doing a configure there is an option for something like --prefix=/foo/bar --hosth6 to optimize the code for my specific hardware. Does anyone know what the "optimal" flags are for an IA-64 in gcc? I realize you can't always use the ones you want, but if you could...? I have gone through a lot of the gcc documentation, but there is so much, and what I have seen so far doesn't cover this. Can anyone point me in the right direction? Ray
