Hi All, As you probably know by now, recent gcc's make use of PPL (Parma Polyhedra Library) and Cloog-PPL (A branch of the Code Generator in the Polyhedral Model making use of PPL for polyhedral functions). If I gather correctly, LFS has up to now avoided including this in favor of sticking closely to traditional build methods and wanting to keep LFS trim and build times shorter. However, despite the extra build times and MBs of added space, I feel these are inclusions worthy of consideration given that their intent is to provide GCC with a methodology to further 'optimizations over a wide variety of processors'. I think the readers are missing out on a good deal of performance/functionality for GCC without these packages.
I'm still reading up on all that's involved with using the 'graphite loop optimizations' as the GCC prereqs refer to them (http://gcc.gnu.org/install/prerequisites.html), so I'm no expert as to all that's involved. I do think LFS should at least look into it. -- JH -- http://linuxfromscratch.org/mailman/listinfo/lfs-dev FAQ: http://www.linuxfromscratch.org/faq/ Unsubscribe: See the above information page
