* testsuite/gcc.dg/graphite/scop-18.c: Remove reduction, test for
the number of detected scops. Copy exact same test for loop
blocking...
* testsuite/gcc.dg/graphite/block-1.c: Fix the number of expected loops
to be blocked as reductions are not handled.
* testsuite/gcc.dg/graphite/block-4.c: ...here. New.
* tree-phinodes.c (remove_phi_nodes): New, extracted from...
* tree-cfg.c (remove_phi_nodes_and_edges_for_unreachable_block):
...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.

block have been translated to graphite.

dependence is correctly implemented.

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,
patch_phis_for_virtual_defs): Removed huge hack.

collect_scop_exit_phi_args, patch_scop_exit_phi_args,
gbb_can_be_ignored, scop_remove_ignoreable_gbbs, ): Removed.

sese_find_uses_to_rename_use, sese_find_uses_to_rename_bb,
sese_add_exit_phis_edge, sese_add_exit_phis_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.
