Just for the record, it is not at all clear that, on modern CPUs, code

The compiler can be quite good at opimizing your code for machine

However, a good assembly langunage programer can write code the is "leaner
and meaner" than a compiler generates. In practical terms, a good C
programmer can often write code that is close, and parallel processing
CPUs where the order of instructions is critical a good compiler
can outdo an assembly language programmer.
HOW do you write 'lean and mean' assembly for a quad core board with AMD
or Pentium stepping (to be chosen at runtime) ?
