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/ext/packed3.C | 25 +++++++++++++++++++++++++ 1 file changed, 25 insertions(+) create mode 100644 gcc/testsuite/g++.dg/ext/packed3.C (limited to 'gcc/testsuite/g++.dg/ext/packed3.C') diff --git a/gcc/testsuite/g++.dg/ext/packed3.C b/gcc/testsuite/g++.dg/ext/packed3.C new file mode 100644 index 000000000..880b5d9b4 --- /dev/null +++ b/gcc/testsuite/g++.dg/ext/packed3.C @@ -0,0 +1,25 @@ +// { dg-do compile } + +// Copyright (C) 2003 Free Software Foundation, Inc. +// Contributed by Nathan Sidwell 15 Jul 2003 + +// Packed fields are unsuitable for direct reference binding. + +struct Unpacked { int i; }; + +void Ref (int &p); +void Ref (Unpacked &p); + +struct __attribute__ ((packed)) Packed +{ + char c; + int i; + Unpacked u; +}; + +void Foo (Packed &p) +{ + Ref (p.i); // { dg-error "cannot bind packed field" "" { target { ! default_packed } } } + Ref (p.u.i); // { dg-error "cannot bind packed field" "" { target { ! default_packed } } } + Ref (p.u); // { dg-error "cannot bind packed field" "" { target { ! default_packed } } } +} -- cgit v1.2.3
