No, the new RA assigns hardregs to every pseudo it can find ;-) I.e. you
would need to change some code. Stack pseudos (on HEAD they are
identified by having a reg number >= max_normal_pseudo) sometimes are not
colored. But in the final rewriting phase they are replaced by stack
slots. This means, that after the new RA run no pseudos without
assignment are left.
Ciao,
Michael.
