From 5258202a81598e8f6f97751a0b0045e5aa1b8978 Mon Sep 17 00:00:00 2001 From: Richard Smith Date: Thu, 3 Oct 2019 01:20:27 +0000 Subject: PR43519: don't inject a diagnostic when constant-evaulation of a pointer-to-member call can't determine a callee. We will have produced a diagnostic already if the callee is known to be unevaluatable, and diagnosing here rejects valid code during potential constant expression checking. llvm-svn: 373553 --- clang/test/SemaCXX/constant-expression-cxx11.cpp | 5 +++++ 1 file changed, 5 insertions(+) (limited to 'clang/test') diff --git a/clang/test/SemaCXX/constant-expression-cxx11.cpp b/clang/test/SemaCXX/constant-expression-cxx11.cpp index bd7094f4d4f..27ad0f654f5 100644 --- a/clang/test/SemaCXX/constant-expression-cxx11.cpp +++ b/clang/test/SemaCXX/constant-expression-cxx11.cpp @@ -1108,6 +1108,11 @@ namespace MemberPointer { static_assert((int Derived::*)(int Mid<0>::*)&Mid<0>::n != (int Derived::*)(int Mid<1>::*)&Mid<1>::n, ""); static_assert(&Mid<0>::n == (int Mid<0>::*)&Base::n, ""); + + constexpr int apply(const A &a, int (A::*f)() const) { + return (a.*f)(); + } + static_assert(apply(A(2), &A::f) == 5, ""); } namespace ArrayBaseDerived { -- cgit v1.2.3
