[Bug tree-optimization/34223] missed optimization - complete unrolling pass before the vectorizer

[steven 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??
