Richard, There's no simple way to do such a check, as the control variable increment stmt is explicitly created in canonicalize_loop_ivs and not in tree-parloops. What we do know is that it is put in the latch because we ask for it when we call canonicalize_loop_ivs from parloops. One way to get the control variable increment stmt is to use canonicalize_loop_ivs() return value and look for the stmts that use it. Do you think I should add all this functionality to the code in order to assert the stmt that is in the latch? or can I skip it ? Thanks, Razya
