<font face="Verdana,Arial,Helvetica,sans-serif" size="2"><div>Hi, all,<br style="box-sizing: inherit;"><br style="box-sizing: inherit;">I am trying to do some improvement to forward the scheduling state between MBB for MI scheduler. It is based on the idea that, if MBB2 has single pred MBB1, then, the MBB1's scheduling state is valid to MBB2. I have posted all the needed patches for months. I really need your input.
