--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Looking again what ICC does here: ICC 16 emits a1 (i.e. like aligned(i_x:1)), ICC 17 emits a8 (i.e. like aligned(i_x:8)), ICC 18 and 19 don't emit anything (i.e. ignore the aligned clause that doesn't tell anything interesting. I guess that is the most reasonable behavior, so will implement it in GCC.
