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>.
It is not possible to define a symbol containing pointers in an assembly source file;
such a symbol must be defined in a Go source file instead.
