If I understand correct, we have the current region scheduler, the
extended basic block scheduler, an extended basic block scheduler
converted to use CFG, and something you refer to as a superblock
scheduler. May I please get access to your CFG-based EBB scheduler and
your superblock scheduler? I am investigating how to improve the GCC
scheduler and would like to include your proposals.
Thanks, David
