A data symbol marked with the <code>NOPTR</code> flag (see above)
is treated as containing no pointers to runtime-allocated data.
A data symbol with the <code>RODATA</code> flag
is allocated in read-only memory and is therefore treated
as implicitly marked <code>NOPTR</code>.
A data symbol with a total size smaller than a pointer
is also treated as implicitly marked <code>NOPTR</code>.
