Richard Biener <rguenth at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Resolution|--- |WONTFIX Status|NEW |RESOLVED --- Comment #6 from Richard Biener <rguenth at gcc dot gnu.org> --- There is nothing to fix, the only possibility would be to move uninit diagnostics earlier. The "regression" is that we now vectorize at -O2, but that's a feature. So you can argue this behavior is a feature. So, WONTFIX.
