--- Comment #1 from Martin Cermak <mcermak at redhat dot com> ---
Other arches seem to work fine in this sense except that s390 has following
limitation in tapset/s390/registers.stp:
=======
if (%{ CONTEXT->user_mode_p %}) {
error("Cannot access function args in user context");
return 0;
}
=======
Not sure why this limitation is there. After commenting it out, int_arg() seems
to return correct values.
