I wrote a prog called jdisasm to disassembly (readable!) java bytecode.
I used it to discover how compilers work, how to do things in java to
get best bytecode if i compile it... something like some people did with
Btw java microcode is too high-level, and translation java->bytecode is
strict, so you can't get any speed boost using bytecode assembly instead of
java. It is just parsed java source described by bytes :(
But java instruction set could be extended with some lowlevel stuff and
SIMD-like vector instructions, it should help multimedia apps a lot!
and as most new cpu has simd-like stuff (sparc, intel, alpha) the
JIT engines can compile them to native ones.
So, I say: java is the "portable assembly language" but currently too
