canonicalize_loop_ivs should add the IV bump in loop->header.
2010-03-16 Sebastian Pop <sebastian.pop@amd.com> * graphite-sese-to-poly.c (graphite_loop_normal_form): Add the IV bump in loop->header. * tree-flow.h (canonicalize_loop_ivs): Updated declaration. * tree-parloops.c (gen_parallel_loop): Add the IV bump in loop->latch. * tree-ssa-loop-manip.c (canonicalize_loop_ivs): Add a new parameter to switch between adding the IV bump in loop->latch or in loop->header.
