pass_init_datastructures is still necessary.
That was the problem-thanks.
New question (or still the original rather), is there existing
functionality to obtain the variables used in a function with external
visibility for that function-or in other words-any variable not local to
that function? is_global_vars() works for globals but misses:
struct foo {
int i;
void bar() {i=10;}
};
In bar, 'i' is not global but is not passed in via arguments either.
referenced_vars contains the 'this' ptr. Is there anything existing that
will obtain 'i' as an external variable w.r.t. bar?
Thanks again,
Mike
