Yes, that is correct.  Isl is needed only for the graphite loop
optimization features of gcc.

But then that leads to a new question: How important and/or useful
is the gcc-graphite optimization?  AFAIK it does improve performance
in many cases.

Also, as opposed to link-time optimization (LTO), gcc-graphite is
stable.

Since gcc-5.1.0 is not that urgent, I'll wait until the isl problem
is sorted out.
