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++.old-deja/g++.jason/rvalue2.C | 18 ++++++++++++++++++ 1 file changed, 18 insertions(+) create mode 100644 gcc/testsuite/g++.old-deja/g++.jason/rvalue2.C (limited to 'gcc/testsuite/g++.old-deja/g++.jason/rvalue2.C') diff --git a/gcc/testsuite/g++.old-deja/g++.jason/rvalue2.C b/gcc/testsuite/g++.old-deja/g++.jason/rvalue2.C new file mode 100644 index 000000000..77189a5eb --- /dev/null +++ b/gcc/testsuite/g++.old-deja/g++.jason/rvalue2.C @@ -0,0 +1,18 @@ +// { dg-do run } +// Test for undesired aliasing. + +struct A { + const A * get_this () const { return this; } +}; + +int main () +{ + A a; + int r = 0; + const A& ar1 = (A)a; + if (&ar1 == &a) + r |= 1; + if (A(a).get_this () == &a) + r |= 2; + return r; +} -- cgit v1.2.3
