While trying to find a solution for this bug http://llvm.org/bugs/show_bug.cgi?id=11235 , I came to the conclusion that the following things can happen while optimizing: - after gvn, I get new constants which are inserted into br and add/sum/..., so there should be at least one more jump-threading and/or instsimplify - after instsimplify, I get new constants which are inserted into br, so there
