How costly would it be if we do as a first data dependence test a call to operand_equal_p on the array references? That certainly would avoid lot of computations downstream in the data dependence test, but would be applied as an initial test to all dependence relations. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=36228
