7856 C_MAYBE_CONST_EXPR to be created, pass the inner expression to
7859 2012-09-14 Joseph Myers <joseph@codesourcery.com>
7862 * c-typeck.c (build_unary_op): Pass original argument of
7863 TRUTH_NOT_EXPR to c_objc_common_truthvalue_conversion, then remove
7864 any C_MAYBE_CONST_EXPR, if it has integer operands.
7865 (build_binary_op): Pass original arguments of TRUTH_ANDIF_EXPR,
7866 TRUTH_ORIF_EXPR, TRUTH_AND_EXPR, TRUTH_OR_EXPR and TRUTH_XOR_EXPR

7870 c_common_truthvalue_conversion.
7871 (c_objc_common_truthvalue_conversion): Build NE_EXPR directly and
7872 call note_integer_operands for arguments with integer operands
7873 that are not integer constants.

7892 * c-decl.c (c_parser_label): Pass true as nested and fix up comments
7893 for nested and empty_ok arguments in the call to
7894 c_parser_declaration_or_fndef.
7896 2012-08-17 Jakub Jelinek <jakub@redhat.com>
