This doesn't look right....

...how come the optimizer didn't clean up the two comparisons at
instructions 001 and 002?  (Looking at the branch destinations, it's
obvious the instruction at 001 can be deleted without affecting the
results.)  Is it broken, or does it just not know how to do that?

This is 1.4T on /sparc.  Fuller details available on request.
