    • [C++] [PR84231] overload on cond_expr in template · 23d63b45 
      A non-type-dependent COND_EXPR within a template is reconstructed with
the original operands, after one with non-dependent proxies is built to
determine its result type.  This is problematic because the operands of
a COND_EXPR determined to be an rvalue may have been converted to denote
their rvalue nature.  The reconstructed one, however, won't have such
conversions, so lvalue_kind may not recognize it as an rvalue, which may
lead to e.g. incorrect overload resolution decisions.

If we mistake such a COND_EXPR for an lvalue, overload resolution might
regard a conversion sequence that binds it to a non-const reference as
viable, and then select that over one that binds it to a const
reference.  Only after template substitution would we rebuild the
COND_EXPR, realize it is an rvalue, and conclude the reference binding
is ill-formed, but at that point we'd have long discarded any alternate
candidates we could have used.

This patch modifies the logic that determines whether a
(non-type-dependent) COND_EXPR in a template is an lvalue, to rely on
its type, more specifically, on the presence of a REFERENCE_TYPE
wrapper.  In order to avoid a type bootstrapping problem, the
REFERENCE_TYPE that wraps the type of some such COND_EXPRs is
introduced earlier, so that we don't have to test for lvalueness of
the expression using the very code that we wish to change.

    • [PR c++/84492] stmt expr ending with overload · 1ea71a82 
      We ICEd when returning a stmt expr that ends with an overloaded
function, because instantiate_type did not know what to do with
STMT_EXPRs.  And it shouldn't have to: the expected type of a stmt
expr cannot be used to resolve its value: an unresolved overload
cannot supply the result of a stmt expr.  Catch that and report the
error in the stmt expr before we have a chance to instantiate it.
