Like this. We should never produce new non-constant value-numbers during phi-translation as that may spuriously increase the maximal set and thus cause insertion of non-redundant values. We do so for NARYs anyway - I'm not sure if that is good though. Maybe the idea is that repeated translation can eventually lead to a known value. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41783
