We currently always schedule for Freeway processors; there are no options to change the instruction scheduling behaviour. As the resulting code is mostly optimal for G6 and earlier processors as well, there's probably not much point in adding these ... (This applies to recent versions of the compiler, e.g. the ones included with kernel 2.4 based distributions. The compilers included with the 2.2 based distros from 2000 have somewhat suboptimal scheduling. The upcoming gcc 3.1 should schedule even better, though ;-)) Bye, Ulrich -- Dr. Ulrich Weigand [EMAIL PROTECTED]
