Well, with an a.out system, gcc 2.8.1 with all the latest patches from the port linked all my KDE apps and whatnot, but they all segfaulted when they ran. The egcs "snapshot" I was using, generated static kde libs fine, but some apps tended to segfault, but generally refused to create useable position independant code (multiply defined symbols). > It's also been observed that egcs is only producing worthwhile code on > i386 and sparc, and the alpha is becoming very important for us. I've heard it been observed from Linux/Alpha users that gcc has very poor 64 bit optimizations anyways. I think I've heard somewhere on one of these fbsd lists that it's not so much a problem paying people to do these types of optimizations, as it is finding the talent to do the grunt work. I wonder if compensation could persuade some Cygnus folks to work a little bit more on the Alpha bits. > Try building the rest of the world, and run with it for a few weeks. Been there, done that.

Yes, but is egcs really _worse_ than gcc 2.7 on the Alpha, or is just not as improved as the x86? Ideally I'd love to see TenDRA imported... Either way, I really haven't seen egcs break any C code, and hell if they got gnat working with it.. - alex To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
