* domwalk.h (struct dom_walk_data): Remove all callbacks except
before_dom_children_before_stmts and after_dom_children_after_stmts.
Rename the two remaining callbacks to just before_dom_children and
after_dom_children. Remove other GIMPLE statement walking bits.
* domwalk.c (walk_dominator_tree): Remove now unsupported features.
* graphite.c: Do not include domwalk.h.
* tree-into-ssa.c (interesting_blocks): New global.
(struct mark_def_sites_global_data): Remove it and names_to_rename.
(mark_def_sites, rewrite_stmt, rewrite_add_phi_arguments,
rewrite_update_stmt, rewrite_update_phi_arguments): Simplify
now that they're not domwalk callbacks.
(rewrite_initialize_block): Rename to...
(rewrite_enter_block): ... this, place after called functions. Test
interesting_blocks, call rewrite_stmt and rewrite_add_phi_arguments.
(rewrite_finalize_block): Rename to...
(rewrite_leave_block): ... this, place after called functions.
(rewrite_update_init_block): Rename to...
(rewrite_update_enter_block): ... this, place after called functions.
Test interesting_blocks, call rewrite_update_stmt and
rewrite_update_phi_arguments.
(rewrite_update_fini_block): Rename to...
(rewrite_leave_block): ... this, place after called functions.
(rewrite_blocks): Remove last argument, simplify initialization of
walk_data.
(mark_def_sites_initialize_block): Rename to...
(mark_def_sites_block): ... this, call mark_def_sites.
(mark_def_sites_blocks): Remove argument, simplify initialization of
walk_data.
(rewrite_into_ssa): Adjust for interesting_blocks_being a global.
(update_ssa): Likewise.
* tree-ssa-dom.c (optimize_stmt): Simplify now that it's not a domwalk
callback.
(tree_ssa_dominator_optimize): Simplify initialization of walk_data.
(dom_opt_initialize_block): Rename to...
(dom_opt_enter_block): ... this, place after called functions. Walk
statements here, inline propagate_to_outgoing_edges.
(dom_opt_finalize_block): Rename to...
(dom_opt_leave_block): ... this, place after called functions.
* tree-ssa-dse.c (dse_optimize_stmt): Simplify now that it's not a
domwalk callback.
(dse_enter_block, dse_record_phi): New.
(dse_record_phis): Delete.
(dse_finalize_block): Rename to...
(dse_leave_block): ... this.
(tree_ssa_dse): Simplify initialization of walk_data.
* tree-ssa-loop-im.c (determine_invariantness, move_computations):
Adjust initialization of walk_data.
* tree-ssa-loop-unswitch.c: Do not include domwalk.h.
* tree-ssa-loop-phiopt.c (get_non_trapping):
Adjust initialization of walk_data.
* tree-ssa-loop-threadedge.c: Do not include domwalk.h.
* tree-ssa-uncprop.c (uncprop_into_successor_phis): Simplify now that
it's not a domwalk callback.
(uncprop_initialize_block): Rename to...
(dse_enter_block): ... this, call uncprop_into_successor_phis.
(dse_finalize_block): Rename to...
(dse_leave_block): ... this.
(tree_ssa_uncprop): Simplify initialization of walk_data.
* Makefile.in: Adjust dependencies.

README
This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the file COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs.html for how to report bugs usefully.
