llvm dev - Apr 2015 - [LLVMdev] Help using getSUnit

Hello,
I’m a grad student working on project using LLVM.
I’m trying to reorder machine instructions within a basic block using a pre emit
pass. the pass relies on checking dependencies therefore getSUnit is a critical
method for this pass. The issue I’m having is I can not access the method SUnit*
getSUnit( MachineInstr *MI) const. I tried declaring my pass class as a
ScheduleDAGInstrs friend but I still can’t have access. Please advice.
Thanks,
Hamza Halli

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
