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

Just cast both values to const TargetRegisterClass*.

I tried something like that yesterday:
const TargetRegisterClass *RC =
is64bit ? &PPC::GPRCRegClass : &PPC::G8RCRegClass;
but I kept getting this error no matter how I arranged it:

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?
Cheers,
