[cfe-dev] Tracing Typedef Chain

[Régis Portalez via cfe-dev]

At what level are you working? Once in llvm IR, you can cast your type to derived type, and then get the element type

I'm struggling to make this work.  Could you possibly give me a more complete example?

If you call `getTypePtr` it should give you the "next" type.

If I have code like this:


typedef int X;
typedef X Y;
typedef Y Z;


Z i = 0;


I have the QualType for i.  getAsString() returns "Z".  getCanonicalType().getAsString() returns "int".


Is there some way to trace the typedef chain such that I get "Z", "Y", "X", and "int"?  Order is not particularly important to me, but it would be nice to get them in that order.
