-/* Compute object sizes for VAR.
- For ADDR_EXPR an object size is the number of remaining bytes
- to the end of the object (where what is considered an object depends on
- OSI->object_size_type).
- For allocation GIMPLE_CALL like malloc or calloc object size is the size
- of the allocation.
- For POINTER_PLUS_EXPR where second operand is a constant integer,
- object size is object size of the first operand minus the constant.
- If the constant is bigger than the number of remaining bytes until the
- end of the object, object size is 0, but if it is instead a pointer
- subtraction, object size is size_unknown (object_size_type).
- To differentiate addition from subtraction, ADDR_EXPR returns
- size_unknown (object_size_type) for all objects bigger than half of the
- address space, and constants less than half of the address space are
- considered addition, while bigger constants subtraction.
- For a memcpy like GIMPLE_CALL that always returns one of its arguments, the
- object size is object size of that argument.
- Otherwise, object size is the maximum of object sizes of variables
- that it might be set to. */
