Richard Biener <rguenth at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Priority|P3 |P2 Known to work| |8.3.1 Known to fail| |9.2.1 --- Comment #4 from Richard Biener <rguenth at gcc dot gnu.org> --- I can confirm this on the GCC 9 branch but trunk is fine apart from at -O1. Maybe tuning/default arch affects this (didn't check, I use x86-64 and generic).
