How to reassign types to their nested component type when initial pointer setup and offsets relate to the parent structure.

[Wall-AF]

I have a situation where a register is being set to the start of a parent structure and offsets are being added to get the member. So far so good! However, the members these offsets refer to belong to an array of embedded structures (with structures within etc.) that are being iterated over (and the array is not at the start of the parent). At the end of the loop, the member's size is being added to aforementioned register, however because Ghidra recognises that register as the parent structure the addition isn't correclty understood and the array elements are missed too, leading to bad C.

I've tried to use offset pointers, but that doesn't work!

Below is a simplified example of the structures involved:

typedef struct tagSubComponent<T> {
    ...;
    T * aData;
} SubComponent;

typedef struct tagComponent {
    int nTotal;
    int nElems;
    ...;
    SubComponent<int> data;
    ...;
} Component;

typedef struct tagParent {
    int nDepth;
    ...;
    Component aComps[5];
    ...;
} Parent;
