Hello,
Here is some temporary source for a class project that exhibits worse
performance (about 15% worse) with the -freduce-all-givs option set. The
performance degrades even more if -fmove-all-movables is set, in case that
helps you at all.
I'm not a compiler guy, so sorry if the source is all I can offer...
Thanks,
Kevin
