Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jakub at gcc dot gnu.org --- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> --- As we use inline functions, it is required to diagnose this only after inlining, and historically we've been doing that during expansion, so that even if a constant materializes through optimizations it is accepted. I think not diagnosing this when the loop is unrolled and only constants make it in is just fine.
