Are you sure that's not happening now?


It is on the Sparc platform. AFAIK Intels netburst (P4) architecture does
the reordering, so there is no benefit in scheduling the code and they don't
bother on the P3 and other x86 clones.

Of course one could fire up shark, part of Apple's CHUD tools, and do sample a run of your java application to see how it utilizes the CPU on a G5 / G4 / etc (at least in theory you could... never tried to peer at JVM generated code with shark, just native library code in response to the java code). That could give you an idea of how good the generated code is.
