Subject: [PATCH] graphite-clast-to-gimple.c (gloog): Do not call
sese_reset_aux_in_loops.
2009-10-26 Sebastian Pop <sebastian.pop@amd.com>
* graphite-clast-to-gimple.c (gloog): Do not call
sese_reset_aux_in_loops.
* graphite-sese-to-poly.c (build_loop_iteration_domains): Pass an
extra argument for domains. Do not use loop->aux.
(build_scop_iteration_domain): Initialize and free domains, pass it
to build_loop_iteration_domains and extract the information from
domains. Do not use loop->aux.
* sese.c (sese_reset_aux_in_loops): Removed.
* sese.h (sese_reset_aux_in_loops): Removed.
