Any suggestions? Hi Gary, You have to write custom encoding logic in C++ for this. This should go in PPCCodeEmitter::emitBasicBlock. I admit this isn't very elegant. A bet...

PPCTargetLowering::EmitInstrWithCustomInserter has a reference to the current MachineFunction for other purposes. Can you use MachineFunction::getRegInfo instead?

Hi Gary, This does not patch cleanly for me (PPCISelLowering.cpp). Can you prepare a updated patch? Thanks, Evan On Jul 10, 2008, at 11:45 AM, Gary Benson wrote: > Cool, that worked.

Just cast both values to const TargetRegisterClass*.

Would it be acceptable to change MachineInstr::getRegInfo from private to public so I can use it from PPCTargetLowering::EmitInstrWithCustomInserter?
