* optional parameter interface: ":opt_count" -> ":opt_flag"
So ":opt_count" should be replaced with ":opt_flag", which sets
its target register to a boolean indicating whether the
immediately preceding parameter was passed or not, rather than a
count of optionals present.
Done (r9254). The canonical sequence for passing optional args now is:
.sub foo
.param <type> arg1 :optional
.param int has_arg1 :opt_flag
.param <type> arg2 :optional
.param int has_arg2 :opt_flag
...
