    c++: non-static member, array bound, sizeof [PR93314]

    N2253 allowed referring to non-static data members without an object in
    unevaluated operands like that of sizeof, but in a constant-expression
    context like an array bound or template argument within such an unevaluated
    operand we do actually need a value, so that permission cannot apply.

            * semantics.c (finish_id_expression_1): Clear

patch for stage 1

A more general, but also more risky, fix for next stage 1.

    c++: constant expressions are evaluated [PR93314]

    My GCC 11 patch for PR93314 turned off cp_unevaluated_operand while
    processing an id-expression that names a non-static data member, but the
    broader issue is that in general, a constant-expression is evaluated even
in
    an unevaluated operand.

    This also fixes 100205, introduced by the earlier patch that couldn't
    distinguish between the different allow_non_constant_p cases.

            PR c++/100205
            PR c++/93314

    gcc/cp/ChangeLog:

            * cp-tree.h (cp_evaluated): Add reset parm to constructor.
            * parser.c (cp_parser_constant_expression): Change
            allow_non_constant_p to int.  Use cp_evaluated.
            (cp_parser_initializer_clause): Pass 2 to allow_non_constant_p.
            * semantics.c (finish_id_expression_1): Don't mess with
            cp_unevaluated_operand here.

    gcc/testsuite/ChangeLog:

            * g++.dg/cpp0x/decltype-nonstatic1.C: New test.
