Why should it be ready to merge the dfa-based scheduler? The bigger
patch, the harder to merge it. My plan is to merge the dfa-based
scheduler into the main trunk and after that use the branch to work on
software pipelining and may be a new interblock insn scheduler.
I agree with Vladimir, software pipelining should need to be available
as a prerequisite for DFA merging. It would only complicate matters.
