Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jakub at gcc dot gnu.org --- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Without -mavx512vl the 128/256-bit pseudos should never be allocated in xmm16-31 registers, so I really wonder how this happens. If you don't mind attaching unreduced code (compressed), I can do the reduction myself.
