Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jakub at gcc dot gnu.org --- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> --- For the xmm16 to xmm31 registers a possible workaround could be to turn those registers fixed on mingw (thus unavailable for register allocation and not call saved). See PR79127.
