Guys, Just got access to a CoreDuo machine, and tested things there. I had to do some hand-translation of assemblies, as I didn't have access to the gnu compiler there, so there's the possibility of error, but it looked like to me that the Core likes the gcc4 x87 code stream better than the gcc3, so I think you'll want to select amongst them according to -march . . . Core is a PIII-based architecture, so when I have a moment I'll try to find a PIII that's still running to see if PIIIs in general like that code stream, while P4s and Athlons like the gcc3 way of things . . .
