[LLVMdev] Help using getSUnit

[Ziqiang Patrick Huang]

If I remember correctly about friend classes

class YourClass {
    friend class ScheduleDAGInstrs;
    ...
}

This only allows ScheduleDAGInstr to access the private/protected members
of YourClass, not the other way around.

Hope this helps,
Patrick
