Yes, I think you are right. I can see a substantial slowdown in compilation times on IA64 HP-UX at -O2 (though it doesn't time out there). gcc 4.0.0 - 81 seconds gcc 3.4.1 - 38 seconds gcc 3.4.0 - 37 seconds gcc 3.3.5 - 89 seconds gcc 3.3.1 - 91 seconds 3.3 is slow, 3.4 is faster, 4.0.0 seems slow agin, I don't have 4.0.* hanging around to test. Looking at a timing report based on the 4.0.0 compiler it looks like half the compile time is spent in the phase "dominance frontiers". I will investigate some more. Steve Ellcey [EMAIL PROTECTED]
