  Tell me one thing: For which processor would you make the asm code?
P-II code is optimized very differently from P4 code. Athlon is also another
different story. So which are you going to optimize for?
  And what happens when in the future Intel and AMD make new processors which
may require specific optimization (eg. because they are 64-bit)? Your asm
code will be optimized for the old architecture and the new compiler will
be unable to optimize it for the new processor. Are you going to write the
asm code for the new processor?
