[LLVMdev] Sethi-Ullman Scheduling

I'm looking over the RR list scheduler and am wondering about how the
Sethi-Ullman numbers are used.

The comments and the code indicate that the node with the lowest S-I
number is scheduled first.  Traditionally S-I scheduling schedules the
node with the highest S-I number first.

What am I missing?
