C++ intermediate bytecode

[Optymizer Sez <optymizer@xxxxxxxxx>]

Hi!

I'd like to ask if there is a way to use GCC in order to compile a C++ source program into machine-independent code (bytecode, perhaps?) and then translate the bytecode into processor-dependent code on the target machine?
Something like the Amsterdam Compiler Kit, but for C++ and x86_64 would be great!

Thanks!
