graphite-isl-ast-to-gimple.c (graphite_verify): Inline into single caller.
2017-09-22 Richard Biener <rguenther@suse.de>
* graphite-isl-ast-to-gimple.c (graphite_verify): Inline into
single caller.
(graphite_regenerate_ast_isl): Do not reset SCEV. Move debug
print of no dependency loops ...
* graphite.c (graphite_transform_loops): ... here.
(canonicalize_loop_closed_ssa_form): Work from inner to outer
loops.
(same_close_phi_node, remove_duplicate_close_phi,
make_close_phi_nodes_unique, defined_in_loop_p): Fold into ...
(canonicalize_loop_closed_ssa): ... here and simplify.
* graphite-optimize-isl.c: Include tree-vectorizer.h.
(optimize_isl): Use dump_printf_loc to tell when we stopped
optimizing because of an ISL timeout.
* gcc.dg/graphite/scop-24.c: New testcase.
