The reason why it is not caught is because we don't cleanup the cfg while doing the loop optimizations, this has been fixed already on the tcb. Oh, by the way I see that sixtrack has regressed on x86 now with your patch applied, I think this is because we still have the same problem as before as ivopts puts the new instruction in an empty BB which becomes from not cleaning up the cfg. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=19038
