--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> --- Yep, but it will for label: # DEBUG ... _1 = xyz; return 'label'. It surely depends on what the users intend (and we have only very few). Likely the tree-vect-slp.cc case (I've only added recently ...) is wrong in this regard since. It wants first non-label non-debug.
