Among the unneeded temporaries, the array constructor (e.g. PR33341) is the
most annoying, i.e. the most often reported, one.

------- Comment #4 from jv244 at cam dot ac dot uk 2009-08-19 10:14 -------
more useless temps...the last two added eat quite a few percent of performance
in CP2K.
This really is an issue where frontend people need to step in to improve the
performance of gfortran.
