Also rewrite out of SSA scalar dependences going outside the SCoP region.
2010-06-12 Sebastian Pop <sebastian.pop@amd.com>
* graphite-clast-to-gimple.c (gloog): Remove call to
sese_adjust_liveout_phis.
* graphite-sese-to-poly.c (scev_analyzable_p): When scev returns an
SSA_NAME, allow it to be handled by rewrite_cross_bb_scalar_deps.
(rewrite_cross_bb_scalar_deps): Handle GIMPLE_PHI nodes: call
rewrite_phi_out_of_ssa.
* sese.c (get_vdef_before_sese): Removed.
(sese_adjust_vphi): Removed.
(sese_adjust_liveout_phis): Removed.
* sese.h (sese_adjust_liveout_phis): Removed.
