From 554fd8c5195424bdbcabf5de30fdc183aba391bd Mon Sep 17 00:00:00 2001 From: upstream source tree Date: Sun, 15 Mar 2015 20:14:05 -0400 Subject: obtained gcc-4.6.4.tar.bz2 from upstream website; verified gcc-4.6.4.tar.bz2.sig; imported gcc-4.6.4 source tree from verified upstream tarball. downloading a git-generated archive based on the 'upstream' tag should provide you with a source tree that is binary identical to the one extracted from the above tarball. if you have obtained the source via the command 'git clone', however, do note that line-endings of files in your working directory might differ from line-endings of the respective files in the upstream repository. --- gcc/testsuite/g++.dg/cpp0x/constexpr-diag1.C | 20 ++++++++++++++++++++ 1 file changed, 20 insertions(+) create mode 100644 gcc/testsuite/g++.dg/cpp0x/constexpr-diag1.C (limited to 'gcc/testsuite/g++.dg/cpp0x/constexpr-diag1.C') diff --git a/gcc/testsuite/g++.dg/cpp0x/constexpr-diag1.C b/gcc/testsuite/g++.dg/cpp0x/constexpr-diag1.C new file mode 100644 index 000000000..183d3f768 --- /dev/null +++ b/gcc/testsuite/g++.dg/cpp0x/constexpr-diag1.C @@ -0,0 +1,20 @@ +// Test that we explain why a template instantiation isn't constexpr +// { dg-options -std=c++0x } + +template +struct A +{ + T t; + constexpr int f() { return 42; } // { dg-error "enclosing class" } +}; + +struct B { B(); operator int(); }; + +constexpr A ai = { 42 }; +constexpr int i = ai.f(); + +constexpr int b = A().f(); // { dg-error "not a constexpr function" } + +template +constexpr int f (T t) { return 42; } // { dg-error "parameter" } +constexpr int x = f(B()); // { dg-error "constexpr function" } -- cgit v1.2.3
