<div dir="auto">Hello, <br>
<br>
<span style="white-space:pre"> Recently, I am reading the code of Instruction schedule in llvm.</span><br>
But it is confused me, because I found llvm have two classes named ScheduleDAGSDNodes and ScheuleDAGInstrs. The first one is used for scheduling SDNode-based DAG, the other is used for MachineInst.<br>
<span style="white-space:pre"> But could we use ScheuleDAGInstrs directly?</span><br>
<br>
Thanks in advance.<br>
<br>
Best Regards<br>
