Subject: Low overhead looping problem

We are porting GCC to our own target. We have encountered a problem during
the optimization phase. It is not able to match the
"decrement_and_branch_until_zero" pattern though we have given the rtl
pattern specified in the manual-- "GNU compiler internals" , topic 8.12 .For
further reference please see the attatched md file.
