Hi,
I thought I sent the following email last Friday but found it in my
drafts folder right now, so let me send it now so that anybody
interested can see what the patch does on Haswell.
I have only skimmed through new messages in the thread. I am now
looking into something else right now but will get back to this matter
next week at the latest.

OK, I have the numbers now too. So far I do not know why, in addition
to 416.gamess, also 465.tonto failed to compile, I will investigate
why only later.
Because the machine is quite a bit slower and everything took forever,
I have measured only unpatched trunk three times and then re-run only
those benchmarks which were more than 2% off when compiled with the
patched compiler.
