I've seen contrary evidence to the conventional wisdom that Sun's compilers
generate faster code. Particularly on x86 architectures, I think GCC gets a
lot of attention and I suspect that recent GCC generates pretty tight code.
Historically we've seen situations where GCC performs better for some code, and
Studio performs better for others.
I don't know that anyone has done a comprehensive comparison between the two
using more recent builds.
Note that I *do* believe that studio probably generates better code for SPARC
-- if only because the Sun engineers have historically had more access to the
h/w folks with a better understanding of the intricacies of the timing details,
etc. for the SPARC cpus.
