As I understand, the memory model are defined to set the accesses to global non-constant data,
i.e. small model has 14 bit access, medium model has 18 bit and large model has 24bit access.
According these memory model, the size of pointer to non-constant data (int *) must be like,
Small = 2 byte(14bit), Medium= 3byte(18bit) , Large = 3byte (24bit).
But I observed that this is the not right scenario considering the small memory model. In the case of small memory model it is also of size 3byte.
This I confirmed as follows -
Created the project with Small memory model in Code warrior 10.6.4
int data = 0xff;
ptr1 = &data;
sizePtr = sizeof(ptr1);
Here the size of pointer 'ptr1' getting in sizePtr as 3.
Also I have confirmed the size of memory allocated for the pointer ptr1by looking into map file and here also it taking as 3 byte.
Please clarify/correct me. Is it a wrong scenario? or compiler is not taking care properly.
