--- Comment #1 from rguenth at gcc dot gnu dot org 2007-11-25 12:50 --- Related to PR18754 - but vectorizer folks say early complete unrolling defeats the vectorizer. So possibly a compromise is to do early complete unrolling only for nested loops. -- rguenth at gcc dot gnu dot org

--- Comment #2 from steven at gcc dot gnu dot org 2007-11-25 13:36 --- Why is this a shift not supported: not vectorized: relevant stmt not supported: D.1652_13 = j_29 3 Is j_29*8 supported (i.e. if you hack this expression to turn it into a MULT_EXPR), does the vectorizer work then??
