Hi Anton,

thanks for this, it is a very useful comparison.

c++ support in LLVM is quite a new thing, so I didn't expect any
miracles. It is a "young" and very dynamic project so I would expect
LLVM to become much much better in near future (gcc as well, but it is
quite conservative in its development, perhaps because it does not have
such a well-defined internal structure); once they add (which might take
a long, since that is definitely not easy) openmp, the results might be
even more interesting.

Is this solved now for? I understand from the other e-mail that it is,
though confirm that to be sure.

Cheers, Vaclav
