Pointer Aliasing
Aliasing is a situation where it is possible for a change to one variable or
reference to affect another. In the C language, aliasing can occur due to the
indirection introduced by pointers. If the address ranges referenced by
two pointers overlap, the pointers alias. Pointer aliasing is another form
of data dependency that the C2H Compiler must consider. Any read or
write operation with a pointer is dependent on all pointer write-
