I'll submit a request outside of this thread later on then.  Thanks for the info!

As far as processing time goes, will that impact getting this patch committed? 
My understanding is end of August for new features for gcc-4.4.

That's an interesting thought then.  I largely left his code intact while I used 
this patch throughout gcc-3.2, 3.3, and 3.4 (I simply updated it to apply to the 
subsequent releases in the 3.x series).  I only converted it to DFA in gcc-4.0, 
which was largely a complete rewrite, using the original patch as a guide to 
learn how DFA changed things around.  Plus, the core information comes from the 
Vr10000 manual anyways, available off www.necel.com.  Considering the very 
original patch was posted once to gcc-patches years ago for gcc-3.0 
consideration, I would be surprised if the e-mail address of that submission 
still goes to him.

Thoughts?
