--- Comment #11 from Paolo Carlini <paolo.carlini at oracle dot com> 2010-10-26 15:42:58 UTC --- Can we please stop talking about nano and giga numbers like kids? If an optimization like complete loop unrolling is involved of course very small or large numbers can be involved, doesn't really contribute anything to the problem talking about the exact figure.
