[LLVMdev] Using isa with derived types

[Zappel-Phillip]

Hello,

I am writing an optimization pass which optimizes code based on an online
pointer analysis algorithm and need to detect pointers which are pointing to
derived types. I have not had any problem identifying pointers in general
using isa<PointerType>(...), but I can't seem to figure out how I can make
sure that the pointer is pointing to a scalar value and not a function,
array, struct, etc.

What am I missing?
