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/not_special.C | 52 ++++++++++++++++++++++++++++++++ 1 file changed, 52 insertions(+) create mode 100644 gcc/testsuite/g++.dg/cpp0x/not_special.C (limited to 'gcc/testsuite/g++.dg/cpp0x/not_special.C') diff --git a/gcc/testsuite/g++.dg/cpp0x/not_special.C b/gcc/testsuite/g++.dg/cpp0x/not_special.C new file mode 100644 index 000000000..6d73bd086 --- /dev/null +++ b/gcc/testsuite/g++.dg/cpp0x/not_special.C @@ -0,0 +1,52 @@ +// I, Howard Hinnant, hereby place this code in the public domain. + +// Test that move constructor and move assignement are special. +// That is, their presence should inhibit compiler generated +// copy ctor or assignment. + +// { dg-options "-std=c++0x" } + +#include + +template struct sa; +template <> struct sa {}; + +struct one {char x[1];}; +struct two {char x[2];}; + +int copy = 0; +int assign = 0; + +struct base +{ + base() {} + base(const base&) {++copy;} + base& operator=(const base&) {++assign; return *this;} +}; + +struct derived + : base +{ + derived() {} + derived(derived&&) {} // { dg-error "argument 1" } + derived& operator=(derived&&) {return *this;} // { dg-error "argument 1" } +}; + +int test1() +{ + derived d; + derived d2(static_cast(d)); // should not call base::(const base&) + assert(copy == 0); + derived d3(d); // { dg-error "lvalue" } + assert(copy == 1); + d2 = static_cast(d); // should not call base::operator= + assert(assign == 0); + d3 = d; // { dg-error "lvalue" } + assert(assign == 1); + return 0; +} + +int main() +{ + return test1(); +} -- cgit v1.2.3
