:> it a few times to build the cache before timing it.

:What is the stddev on your measurements ?
:
:a delta-T 1 second need a very tight stddev to be significant.
The timing was +/- 0.5 second ( I ran the test four times ). But, remember,
this is not comparing against GCC. This was simply comparing various
EGCC optimization features. stddev on ~160 seconds +/- 0.5s is basically
0, so it is not a useful measurement beyond noting that it is near 0.
I would love to see a comparison against GCC. I blew away my GCC :-( and
do not want to spend time reinstalling it.
