I know;)

> Does the good old version gets vectorized?

I don't have any working 4.5 version, but 4.4.2 is working. The differences are

(4.4.2)

where_2.f90:5: note: LOOP VECTORIZED.
where_2.f90:2: note: vectorized 1 loops in function.

(4.5.0)

where_2.f90:11: note: LOOP VECTORIZED.
where_2.f90:11: note: not vectorized: relevant stmt not supported: cond.23_79 =
D.1255_78 > 6;

where_2.f90:11: note: not vectorized: relevant stmt not supported: cond.15_57 =
D.1238_56 == 0;

where_2.f90:11: note: not vectorized: relevant stmt not supported: cond.9_43 =
D.1227_42 < 0;

where_2.f90:5: note: LOOP VECTORIZED.
where_2.f90:2: note: vectorized 2 loops in function.

I'll attach the files dumped with -fdump-tree-vect for 4.4 and 4.5.

Note that I make a mistake when looking to my log files: the last working
revision is 149758 and the first failing one is 150041.
