if all goes well.  I will do bootstrap & regtesting on the archs
I have available (x86_64, i?86, ppc, ppc64, ia64, s390 and s390x).

I am absolutely thrilled to test it on our weather forecasting system. The top routine in our profile looks a *lot* like the loop you got such an improvement on in SPEC's mgrid ...

Unfortunately, the improvement is not as large as I had hoped:

Before the merge of the alias-improvements branch into mainline:
00 UTC run 20090405, last file produced:

-rw-r--r-- 1 hirlam hirlam  21492000 2009-04-05 08:31 fc20090405_00+048ve

After the merge of the alias-improvements branch into mainline:
00 UTC run 20090406, last file produced:

-rw-r--r-- 1 hirlam hirlam  21648000 2009-04-06 08:29 fc20090406_00+048ve

So the improvement is 2 minutes for a 3.5 hour run (~ 1%).

Kind regards,
