Re: [RFC] propagating loop dependences from trees to RTL (for SMS)
I will pull a patch together tomorrow. There is currently nothing in
the code for keeping the region stuff up to date as changes are made to
the cfg. For most changes this would not be hard, but for some it is
really hard.

4. Other ideas?
Preserving the information about loops throughout the
optimizations, and
just keeping this information attached at the loop description
would by
far be the cleanest approach -- admitedly also the one that
requires the
greatest amount of work.
Shouldn't the regions patch allow us to preserve loops quite easily?
Any pointer to this "regions patch" ?
Thanks,
