--- Comment #8 from Uroš Bizjak <ubizjak at gmail dot com> --- (In reply to Levy Hsu from comment #5) > case E_V16QImode: > mode = V8HImode; > gen_shr = gen_vlshrv8hi3; > gen_shl = gen_vashlv8hi3; Hm, why vector-by-vector shift here? Should there be a call to gen_lshrv8hi3 and gen_ashlv8hi3 instead?
