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-array-ptr5.C | 32 +++++++++++++++++++++++ 1 file changed, 32 insertions(+) create mode 100644 gcc/testsuite/g++.dg/cpp0x/constexpr-array-ptr5.C (limited to 'gcc/testsuite/g++.dg/cpp0x/constexpr-array-ptr5.C') diff --git a/gcc/testsuite/g++.dg/cpp0x/constexpr-array-ptr5.C b/gcc/testsuite/g++.dg/cpp0x/constexpr-array-ptr5.C new file mode 100644 index 000000000..d58f254f6 --- /dev/null +++ b/gcc/testsuite/g++.dg/cpp0x/constexpr-array-ptr5.C @@ -0,0 +1,32 @@ +// { dg-options -std=c++0x } + +template +constexpr T do_last(T* x, int n) { + return x[n - 1]; // +} + +template +constexpr T last(T (&x)[N]) { + return do_last(x, N); +} + +constexpr bool is_negative(int x) { return x < 0; } + +template +struct IsNegative { + constexpr bool operator()(const T& x) { + return x < T(0); + } +}; + +template +constexpr bool has_neg(T (&x)[N], Pred p) { + return p(last(x)); // Line 22 +} + +constexpr int a[] = {1, -2}; + +constexpr auto answer1 = has_neg(a, IsNegative{}); // Line 27 +constexpr auto answer2 = has_neg(a, is_negative); + +static_assert(answer2 == answer1, "Error"); -- cgit v1.2.3
