Hi Derek,

> Another option might be to use a similar factoring (which splits the code that must deal with virtual registers out from the code that need not), but not actually create 2 different MachineFunctionPasses. We could say that the pass itself supports virtual registers, but we'd have better organization and clearer separation.


This may be the cleanest solution.

Could you prepare a patch for that direction?

Thanks,
-Quentin
