PR middle-end/45297
* graphite-poly.c (new_poly_bb): Returns a poly_bb_p. Do not take
the reduction bool in parameter. Clear PBB_IS_REDUCTION. Set GBB_PBB.
* graphite-poly.h (new_poly_bb): Update declaration.
(gbb_from_bb): Moved here...
(pbb_from_bb): New.
* graphite-sese-to-poly.c (var_used_in_not_loop_header_phi_node):
Removed.
(graphite_stmt_p): Removed.
(try_generate_gimple_bb): Returns a gimple_bb_p. Do not pass in
sbitmap reductions. Always build a gimple_bb_p. Do not call
new_poly_bb.
(build_scop_bbs_1): Do not pass in sbitmap reductions.
(build_scop_bbs): Same.
(gbb_from_bb): ... from here.
(add_conditions_to_constraints): Moved up.
(analyze_drs): New.
(build_scop_drs): Call analyze_drs. Remove all the PBBs that do
not contain data references.
(new_pbb_from_pbb): New.
(insert_out_of_ssa_copy_on_edge): Call new_pbb_from_pbb after a
block is split.
(rewrite_close_phi_out_of_ssa): Update call to
insert_out_of_ssa_copy_on_edge.
(rewrite_reductions_out_of_ssa): Now static.
(rewrite_cross_bb_scalar_deps_out_of_ssa): Same.
(split_pbb): New.
(split_reduction_stmt): Call split_pbb.
(translate_scalar_reduction_to_array): Pass in the scop, do not
pass in the sbitmap reductions.
(rewrite_commutative_reductions_out_of_ssa_close_phi): Same.
(rewrite_commutative_reductions_out_of_ssa_loop): Same.
(rewrite_commutative_reductions_out_of_ssa): Same.
(build_poly_scop): Call build_scop_bbs,
rewrite_commutative_reductions_out_of_ssa,
rewrite_reductions_out_of_ssa, and
rewrite_cross_bb_scalar_deps_out_of_ssa. Move build_scop_drs
before scop_to_lst.
* graphite-sese-to-poly.h (rewrite_commutative_reductions_out_of_ssa):
Removed declaration.
(rewrite_reductions_out_of_ssa): Same.
(rewrite_cross_bb_scalar_deps_out_of_ssa): Same.
(build_scop_bbs): Same.
* graphite.c (graphite_transform_loops): Do not initialize reductions.
Do not call build_scop_bbs,
rewrite_commutative_reductions_out_of_ssa,
rewrite_reductions_out_of_ssa, and
rewrite_cross_bb_scalar_deps_out_of_ssa.
* sese.h (struct gimple_bb): Add field pbb.
(GBB_PBB): New.
* gcc.dg/graphite/pr45297.c: New.
