Add POINTER_PLUS_EXPR - Improvement?

It seems we miss the POINTER_PLUS_EXPR. In most cases in tree-scalar-evol.c and
tree-chrec.c it is handled like a PLUS_EXPR. If I add it, the test case passes
the front end, but fails again in gloog() with:

I will have to think about the patch. Opinions?

        graphite statement for the basic block.
        (free_graphite_bb): Do not free GBB_DATA_REFS: this is a bug
        in free_data_ref that calls BITMAP_FREE (DR_VOPS (dr)) without 
        reason.
        (recompute_all_dominators, graphite_verify,

        dependence is correctly implemented.

        Use replace_exp and update_stmt.
        (expand_scalar_variables_expr): Same.  Use the map to get the
        new names for the renaming of induction variables and for the
        renaming of variables after a basic block has been copied.
        (expand_scalar_variables): Same.

        do not move them.  Finally, in call cleanup_tree_cfg in gloog.

        consistency of the SSA, loops and dominators information.

        Fix testsuite/gfortran.dg/graphite/id-4.f90.
        * graphite.c (scan_tree_for_params): Do not compute the multiplicand
        when not needed.

2008-12-11  Sebastian Pop  <sebastian.pop@amd.com>

        * graphite.c (build_scops_1): Initialize open_scop.exit

...here.
        * tree-flow.h (remove_phi_nodes, canonicalize_loop_ivs): Declared.
        * Makefile.in (graphite.o): Depend on value-prof.h.
        (graphite.o-warn): Removed -Wno-error.
        * tree-parloops.c (canonicalize_loop_ivs): Allow reduction_list 
        to be a NULL pointer.  Call update_stmt.  Return the newly created 
        cannonical induction variable.

        * graphite.h (debug_rename_map): Declared.  Fix some comments.

        * graphite.c: Reimplement the code generation from graphite to gimple.
        Include value-prof.h.
        (loop_iv_stack_get_iv): Do not return NULL for constant substitutions.
        (get_old_iv_from_ssa_name): Removed.
        (graphite_stmt_p): New.
        (new_graphite_bb): Test for useful statements before building a
        graphite statement for the basic block.
        (free_graphite_bb): Do not free GBB_DATA_REFS: this is a bug
        in free_data_ref that calls BITMAP_FREE (DR_VOPS (dr)) without 
        reason.
        (recompute_all_dominators, graphite_verify,
        nb_reductions_in_loop, graphite_loop_normal_form): New.
        (scop_record_loop): Call graphite_loop_normal_form.
        (build_scop_loop_nests): Iterate over all the blocks of the
        function instead of relying on the incomplete information from
        SCOP_BBS.  Return the success of the operation.
        (find_params_in_bb): Use the data from GBB_DATA_REFS.
        (add_bb_domains): Removed.
        (build_loop_iteration_domains): Don't call add_bb_domains.
        Add the iteration domain only to the basic blocks that have been
        translated to graphite.
        (build_scop_conditions_1): Add constraints only if the basic
        block have been translated to graphite.
        (build_scop_data_accesses): Completely disabled until data
        dependence is correctly implemented.
        (debug_rename_elt, debug_rename_map_1, debug_rename_map): New.
        (remove_all_edges_1, remove_all_edges): Removed.
        (get_new_name_from_old_name): New.
        (graphite_rename_variables_in_stmt): Renamed 
        rename_variables_in_stmt.  Call get_new_name_from_old_name.
        Use replace_exp and update_stmt.
        (is_old_iv): Renamed is_iv.
        (expand_scalar_variables_stmt): Extra parameter for renaming map.
        Use replace_exp and update_stmt.
        (expand_scalar_variables_expr): Same.  Use the map to get the
        new names for the renaming of induction variables and for the
        renaming of variables after a basic block has been copied.
        (expand_scalar_variables): Same.
        (graphite_rename_variables): Renamed rename_variables.
        (move_phi_nodes): Removed.
        (get_false_edge_from_guard_bb): New.
        (build_iv_mapping): Do not insert the induction variable of a
        loop in the renaming iv map if the basic block does not belong
        to that loop.
        (register_old_new_names, graphite_copy_stmts_from_block,
        copy_bb_and_scalar_dependences): New.
        (translate_clast): Heavily reimplemented: copy basic blocks,
        do not move them.  Finally, in call cleanup_tree_cfg in gloog.
        At each translation step call graphite_verify ensuring the 
        consistency of the SSA, loops and dominators information.
        (collect_virtual_phis, find_vdef_for_var_in_bb,
        find_vdef_for_var_1, find_vdef_for_var,

        rewrite_into_sese_closed_ssa): New.
        (gloog): Remove dead code.  Early return if code cannot be
        generated.  Call cleanup_tree_cfg once the scop has been code
        generated.
        (graphite_trans_scop_block, graphite_trans_loop_block): Do not 
        block loops with less than two loops.
        (graphite_apply_transformations): Remove the call to
        scop_remove_ignoreable_gbbs.
        (limit_scops): When build_scop_loop_nests fails, continue on next scop.
        Fix open_scop.entry.
        (graphite_transform_loops): Call recompute_all_dominators: force the
        recomputation of correct CDI_DOMINATORS and CDI_POST_DOMINATORS.
        Call initialize_original_copy_tables and free_original_copy_tables
        to be able to copy basic blocks during code generation.

        (value_clast): New union.
        (clast_to_gcc_expression): Fix type cast warning.
