There is a LONG LONG way to go before the compiler will be ready for us (but considering the progress that they have been making, a "long long way" might mean a month or so :-)). I think that they are doing it "right", and moving aggressively. I have been making my own PPRO optimizations, and been tracking their work. I'll likely offer the stuff to them, if I see that my stuff is good enough. (I am NOT a compiler person, but have played with GCC internals since the 1.2X days.) We should do better to support the effort, and optionally offer the EGCS compiler as a port. My guess is that it won't be ready to be the 3.0-RELEASE default compiler. -- John | Never try to teach a pig to sing, dyson@freebsd.org | it just makes you look stupid, and jdyson@nc.com | it irritates the pig.
