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/opt/nrv10.C | 48 ++++++++++++++++++++++++++++++++++++++++ 1 file changed, 48 insertions(+) create mode 100644 gcc/testsuite/g++.dg/opt/nrv10.C (limited to 'gcc/testsuite/g++.dg/opt/nrv10.C') diff --git a/gcc/testsuite/g++.dg/opt/nrv10.C b/gcc/testsuite/g++.dg/opt/nrv10.C new file mode 100644 index 000000000..d4cb92c33 --- /dev/null +++ b/gcc/testsuite/g++.dg/opt/nrv10.C @@ -0,0 +1,48 @@ +// PR c++/25979 +// Bug: we were eliding too many temporaries, so that a1 was used +// as both 'a' and 'x' in the second operator+. +// { dg-do run } + +struct A +{ + A() : data1_(0), data2_(0) {} + A(int i, int j) : data1_(i), data2_(j) {} + A operator+(int); + friend A operator+(int, const A&); + ~A() {} +//private: + int data1_; + int data2_; +}; + +extern bool x; + +extern "C" void abort (); + +int main() +{ + A a1(1,2); + a1 = (x ? a1 + 3 : 3 + a1); + if (a1.data1_ != 3 || a1.data2_ != 2) + abort (); +} + +bool x = false; + +A +A::operator+(int i) +{ + A a; + a = *this; + a.data2_ = i; + return a; +} + +A +operator+(int i, const A& x) +{ + A a; + a = x; + a.data1_ = i; + return a; +} -- cgit v1.2.3
