Author: jakub Date: Tue May 11 18:12:28 2010 New Revision: 159286 URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=159286 Log: PR c++/44062 * c-parser.c (c_parser_expression): Mark LHS of a comma expression as read if it is a decl, handled component or COMPOUND_EXPR with that on the RHS. * c-typeck.c (c_process_expr_stmt): Mark RHS of COMPOUND_EXPR if it is a decl or handled component. * semantics.c (finish_expr_stmt): Don't call mark_exp_read here... * cvt.c (convert_to_void): ... but here. If expr is a COMPOUND_EXPR, look at its second operand. * c-c++-common/Wunused-var-7.c: New test. * g++.dg/warn/Wunused-var-9.C: New test.
