------- Comment #9 from pcarlini at suse dot de 2007-02-05 18:53 -------
Referring to Comment #7, currently in mainline, 4_2-branch and even 4.1.1 the
only loop not eliminated at -O2 is foo2 - actually, that is pretty good for the
library: very nice that we don't need special code to avoid foo4. Anyway,
should we eliminate foo2 too?
