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/other/offsetof2.C | 47 ++++++++++++++++++++++++++++++++++ 1 file changed, 47 insertions(+) create mode 100644 gcc/testsuite/g++.dg/other/offsetof2.C (limited to 'gcc/testsuite/g++.dg/other/offsetof2.C') diff --git a/gcc/testsuite/g++.dg/other/offsetof2.C b/gcc/testsuite/g++.dg/other/offsetof2.C new file mode 100644 index 000000000..3ab63981d --- /dev/null +++ b/gcc/testsuite/g++.dg/other/offsetof2.C @@ -0,0 +1,47 @@ +// { dg-do run } +// { dg-options -Wold-style-cast } + +// Copyright (C) 2003 Free Software Foundation, Inc. +// Contributed by Nathan Sidwell 22 Apr 2003 + +// DR273 POD can have an operator&, offsetof is still required to work + +#include + +struct POD1 +{ + int m; + + void *operator& () const {return 0;} // yes, still a pod! +}; + +struct POD2 +{ + int m; +}; + +void *operator& (POD2 const &) {return 0;} // ouch! + +struct POD3 +{ + int prefix; + + POD1 m; +}; + +struct POD4 +{ + int prefix; + + POD1 m; +}; + +int main () +{ + if (offsetof (POD3, m) != sizeof (int)) + return 1; + if (offsetof (POD4, m) != sizeof (int)) + return 2; + return 0; +} + -- cgit v1.2.3
