re PR c++/5520 (Add a warning to detect empty body of if statements (like in the C frontend))
2006-01-20 Dirk Mueller <dmueller@suse.com>
PR c++/5520
* c-parser.c (c_parser_if_body): Use build_empty_stmt()
instead of a special NOP marker.
* c-typeck.c (c_finish_if_stmt): Remove obsoleted special
NOP marker handling.
* c-common.h (empty_body_warning): Add forward declaration.
* c-common.c (empty_body_warning): Add (from c_finish_if_stmt).
Now uses IS_EMPTY_STMT() instead of special NOP markers.
* semantics.c (finish_if_stmt): Call empty_body_warning.
* parser.c (cp_parser_implicitly_scoped_statement):
Mark empty statement with an empty stmt.
* g++.dg/warn/empty-body.C: New.
