Earlier, if the QualType was sugared, then we would error out as it was not a pointer type, for example, typedef int *int_star; int_star __ptr32 p; Now, if ptr32 is given we apply it if the raw Canonical Type (i.e., the desugared type) is a PointerType, instead of only checking whether the sugared type is a pointer type. As before, we still disallow ptr32 usage if the pointer is used as a pointer to a member. Differential Revision: https://reviews.llvm.org/D130123
