I've just done, but unfortunately it reduces to a test-case that's not useful:

typedef struct tree_node *tree;
struct A {
  tree type;
};
struct tree_node {
  A typed;
};
bool vect_recog_mask_conversion_pattern_load;
void fn1(tree);
void fn2() {
  tree __trans_tmp_3, lhs;
  if (vect_recog_mask_conversion_pattern_load) {
    __trans_tmp_3 = lhs;
    fn1((__trans_tmp_3->typed.type));
  }
}

Any idea how to write reduce script properly to isolate that?

Thanks,
Martin
