Which begs the question I've tried to ask a number of times in different forums. Who's working on P4 optimizations and code generation for the P4? Sure, i386 code will run but the benchmarks seem to indicate that peak performance is heavily dependent on a good optimizing compiler. A query to the gcc mailing list returned no responses.
