Just verified that current trunk is not yet able to vectorize the test.f90
code,
it would be cool if this could be fixed (maybe along the lines of Richard's
previous patch?) as this is similar to CP2K's kernel routines:

I don't think any of those tests would be made correct simply by replacing 'f'
with 'f'
Maybe they would have been accepted by GCC 2.95 with the ampersand present, but
current GCC correctly requires 'C::f'

is this 'scalar code vectorization' the same as the SLP that has already been
