-        * tree-ssa-pre.c: Fix typo in comment.
-        (init_antic, fini_antic): Add explicit funtions for
-        initializing and deinitializing ANTIC and AVAIL sets.
-        (create_expression_by_pieces): Fix typo in comment.
-        Remove redundant set of new_stuff and use NULL_TREE instead of
-        NULL.
-        (execute_pre): Eventually dump details about ANTIC_IN.
