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-ex2.C | 23 +++++++++++++++++++++++ 1 file changed, 23 insertions(+) create mode 100644 gcc/testsuite/g++.dg/cpp0x/constexpr-ex2.C (limited to 'gcc/testsuite/g++.dg/cpp0x/constexpr-ex2.C') diff --git a/gcc/testsuite/g++.dg/cpp0x/constexpr-ex2.C b/gcc/testsuite/g++.dg/cpp0x/constexpr-ex2.C new file mode 100644 index 000000000..29e835c4b --- /dev/null +++ b/gcc/testsuite/g++.dg/cpp0x/constexpr-ex2.C @@ -0,0 +1,23 @@ +// { dg-do compile } +// { dg-options "-std=gnu++0x" } + +// From N2235 + +// 4.5.3 constant expressions + +// p 4 +struct A { + constexpr A(int i) : val(i) { } + constexpr operator int() { return val; } + constexpr operator long() { return -1; } +private: + int val; +}; + +template struct X { static const int i = I; }; +constexpr A a = 42; + +X x; // OK: unique conversion to int +int ar[X::i]; // also OK +int ary[a]; // { dg-error "ambiguous|conversion|array" } ambiguous conversion + -- cgit v1.2.3
