Humbly, I'd like to suggest again that we have a look to the assembly produced
by other compilers. I remember that some GCC contributors have access to
compilers such as ICC, XLC++, Sun, etc. and I don't think we should strive at
all costs for perfect optimization, if that means keeping busy our best
contributors for months and risking producing wrong code. We can always return
to the issue later, as an enhancement.
