[Bug tree-optimization/17165] pass by reference inhibits vectorization


------- Additional Comments From pinskia at gcc dot gnu dot org  2004-08-24 15:14 -------
Confirmed on the mainline (since the vectorizer was merged):
Access function of ptr: {(T &)&a, +, 4}_1
step: 4,  init: (T &)&a
loop at pr17165.cc:4: not vectorized: non constant init/step for pointer access.
loop at pr17165.cc:4: bad data references.
