THere's still the opportunitity to use range information to simplify a conditional. However, fixing that is just basically iterating VRP in response to CFG changes -- not something we're going to do as it's simply too expensive. Thus I'm changing the state of this bug to WONTFIX. -- law at redhat dot com changed: What |Removed |Added ---------------------------------------------------------------------------- Status|NEW |RESOLVED Resolution| |WONTFIX http://gcc.gnu.org/bugzilla/show_bug.cgi?id=21829
