[LLVMdev] Variable-length Phi-node

[William Moses]

All,

Is it possible to create something which has the same effect of a
variable-length phi node in the C++ api. Specifically, create a phi-node
where the number of incoming values is not known at the time of its
creation.

If there is no such way of creating a phinode like that, would it be
possible to create a dummy instruction and perform a replaceAllUsesWith? If
so, what should the dummy instruction be?

Thanks,
Billy
