Keywords: GCC, performance, question

Is there a comparison of gcc's performance against other compilers,
like AT&T cc, and HP's optimizings compiler? Especially one that
compares by optimizations like register allocation, loop unrolling,
inlining, etc. How does the different versions of gcc (for different
architectures) compare against each other in various optimizations.
Also is there a version of gcc that generate predicated code using the
cmove instruction? Does you know where I can get source?

I'm doing this project in my spare time to learn about compiler
optimizations so if anyone can give me more pointers, I'd really
appreciate it.
