If a function has no arguments and no results,
the pointer information can be omitted.
This is indicated by an argument size annotation of <code>$<i>n</i>-0</code>
on the <code>TEXT</code> instruction.
Otherwise, pointer information must be provided by
a Go prototype for the function in a Go source file,
even for assembly functions not called directly from Go.
