compilers (C/C++)

Here's a somewhat highly technical subject https://www.sharkyforums.com/images/.../2005/06/5.gif

Does anyone know of good compilers for x86 linux? I'm doing some work which is quite intensive and the gnu gcc / g++ compilers just don't cut it. I know that if I had time to hand optimize (loop unrolling, ...) the assembly code the compiler creates I would achieve quite a performance gain. I'm by _no_ means an expert in compilers, but I thought we might be able to get an interesting thread going talking about compiler technology.

I'd be happy to talk about it with you. More information would be good. Yes, it's true that a good compiler can give you a good speed up. Using assembly can give a bit more. But generally a better algorithm is the way to go. You should be generally able to find a few spot areas in code that give significant performance increases.

You might get better answers to this question in the programming forum.

I think Intel's VTune compiler has a Linux version but VTune is not known for reliability and the Linux version would still be new. AFAIK most people working in Linux use gcc.
