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*.

You need to insert new basic blocks and update CFG to accomplish this. There is a hackish way to do this right now. Add a pseudo instruction to represent this operation and mark it usesCustomDAGSchedInserter. This means the intrinsic is mapped to a single (pseudo) node. But it is then expanded into instructions that can span multiple basic blocks. See

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