I wonder how the CALL handling is correct in > using add_non_frame_wild_read then for the case we pass the address > of a frame variable to it. See kill_on_calls. > So I suppose add_wild_read () would do the trick. Nope, since it also calls free_read_records. > So better would be to include the original effects of the insn _plus_ > the non-frame wild read effect. Yes, exactly.
