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/nrv2.C | 28 ++++++++++++++++++++++++++++ 1 file changed, 28 insertions(+) create mode 100644 gcc/testsuite/g++.dg/opt/nrv2.C (limited to 'gcc/testsuite/g++.dg/opt/nrv2.C') diff --git a/gcc/testsuite/g++.dg/opt/nrv2.C b/gcc/testsuite/g++.dg/opt/nrv2.C new file mode 100644 index 000000000..4ffc07587 --- /dev/null +++ b/gcc/testsuite/g++.dg/opt/nrv2.C @@ -0,0 +1,28 @@ +// Test for the named return value optimization, this time with inlining. +// { dg-do run } +// { dg-options -O2 } + +int c; +int d; + +struct A +{ + A() { ++c; } + A(const A&) { ++c; }; + ~A() { ++d; } +}; + +inline A f () +{ + A a; + return a; +} + +int main () +{ + { + A a = f (); + } + + return !(c == 1 && c == d); +} -- cgit v1.2.3
