------- 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.

I would like to ping this PR... progress here seems valuable, and typical stage

------- Comment #2 from dfranke at gcc dot gnu dot org  2009-01-04 00:40 -------
Among the unneeded temporaries, the array constructor (e.g. PR33341) is the
most annoying, i.e. the most often reported, one.
