[LLVMdev] Lowering formal pointer arguments

[Christoph Erhardt]

Hi Patrik,

> DAG.getMachineFunction().getFunction() only works in LowerFormalArguments (there it returns the callee), not in LowerCall (where it returns the caller, rather than the callee). You need to pass more information about the function type to LowerCall (besides partial information such as the isVarArg parameter).

please do! I have been facing the same problem and am very interested in
a clean solution for this.

Best regards,
Christoph
