+Subject: [PATCH] [Build, Graphite] PR64017 - support ISL-0.14 (gcc/configure.ac and gcc/graphite*.c)
+
+This patch adds a configure check for isl_schedule_constraints_compute_schedule,
+which is new in ISL 0.13 - and uses it for conditional compilation.
+
+The graphite*c patch is based on the one of Jack Howarth,
+https://gcc.gnu.org/ml/gcc-patches/2014-11/msg00906.html - without checking
+whether the ISL replacements make sense.
+
+With the patch, I have successfully bootstrapped GCC with ISL 0.12.2 and
+ISL 0.14 (both using an in-tree build).  [I still have to regtest the two
+variants and I also want to do a system-ISL built with ISL 0.12.2]
+
+Is the patch OK for the trunk?
+
+Tobias
+
+PS: I'd be happy if some others could run additional tests.
+
+PPS: If the patch is in, can someone put ISL 0.14 to infrastructure? Then
+one can update contrib/download_prerequisites - such that the graphite
+failure is at least fixed for in-tree builds (cf. PR64017, PR62289).
