I don't understand the comment. Comparisons constructed due to may_eliminate_iv are always either EQ_EXPRs or NE_EXPRs. Comparing directly with a value in a different type (regardless of what comparison operator is used) is however always an invalid gimple. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=19937
