Sebastian already pointed out. We will apply them together, such that we get the documentation with the features. Cheers Tobi

I find this a bit confusing. Assuming I managed to parse this correct, how about saying "The former is the default right now. It can be downloaded from...and configured with" (and omit the "The code in..."). On the other hand, if this is the default, why does it need to be configured explicitly? > The @option{--with-cloog} configure option should be used if CLooG is > not installed in your default library search path. Ah, yes. So is this only necessary for the other case, CLooG 0.16, or for CLooG-PPL as well? Or in both cases, in which case this should be made explicit? > +CLooG 0.16 support is still in testing stage, but will be the default in future > +gcc releases.

And the first line is too long Now you are really loosing me. CLooG-PPL 0.15 is configured with --with-ppl, whereas CLooG 0.16 via --enable-cloog-backend=isl ?? Gerald

CLooG-PPL is configured with --with-ppl. CLooG 0.16 is configured with --with-isl (I think this is the default though so maybe not necessary). To use CLooG 0.16, GCC itself must be configured with --enable-cloog-backend=isl. The default is --enable-cloog-backend=ppl-legacy. Could you also comment on whether or not PPL is still a dependency of GCC when using CLooG 0.16 with the ISL backend? I'm a little confused on this matter. Also, if CLooG-PPL will remain the default, will the minimum PPL version remain 0.10 or be bumped to 0.11? If the latter, you will need to update the stated minimum CLooG-PPL filename to cloog-ppl-0.15.10.tar.gz.
