--- Comment #3 from vincenzo Innocente <vincenzo.innocente at cern dot ch> --- what I am interested in is NOT a constant array, more a small-size "sparse"-matrix that I can build explicitly at run time from other sources. I have examples using Eigen if of any interest ( https://godbolt.org/z/2L9OBU ) Clang is excellent in optimizing out zeros and ones, gcc in vectorization. I hope to get the best of the two!
