I just committed a patch to lang/gcc6-devel that adds a new option
GRAPHITE which enables support for Graphite loop optimizations and
am looking into pushing this back into the gcc5-devel and later
gcc5 ports.
Since this pulls in libisl as an additional dependency and I have
only seen two requests for this (including yours) so far, I'm a
little hesitant to make enable this option by default.
What do you think? (Patch below.)
Gerald
