--- Comment #10 from jbeulich at suse dot com --- (In reply to Hongtao.liu from comment #9) > We don't have single instruction for V8HI/V16QImode broadcast without AVX2, > that's why the first splitter only have VI48_128. Does this matter? The splitters are about subsuming the "not". How the "vec_duplicate" is carried out isn't really relevant here, is it?
