Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jakub at gcc dot gnu.org --- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Can't reproduce either. Maybe it got fixed with r264675 aka PR87149 fix? Before that change indeed those could be CODE_FOR_nothing if using a cross without assembler or with too old assembler that didn't support the power8 instructions.
