Makefile.in (OBJS): Add graphite-optimize-isl.o.
2012-07-04 Tobias Grosser <tobias@grosser.es>
Michael Matz <matz@suse.de>
* Makefile.in (OBJS): Add graphite-optimize-isl.o.
(graphite-optimize-isl.o): Add dependencies.
* common.opt (floop-nest-optimize): New flag.
* doc/invoke.texi (floop-nest-optimize): Document.
* graphite-dependences.c (compute_deps): Export.
* graphite-poly.h (compute_deps): Declare.
* graphite-optimize-isl.c: New file.
* graphite-poly.c (apply_poly_transforms): Run the loop
nest optimizer.
* tree-ssa-loop.c (gate_graphite_transforms): Enable graphite
if -floop-nest-optimize is enabled.
