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
