--- Comment #1 from vincenzo Innocente <vincenzo.innocente at cern dot ch> 2011-10-03 08:40:53 UTC --- manage to vectorize this int j[1024]; void foo5() { for (int i=0; i!=N; ++i) j[i] = (a[i]<b[i] ? -1 : 0) & (c[i]<d[i] ? -1 : 0); } which is not bad, still a funny syntax (at least for those who are not used to code in native SSE)
