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/packed1.C | 29 +++++++++++++++++++++++++++++ 1 file changed, 29 insertions(+) create mode 100644 gcc/testsuite/g++.dg/other/packed1.C (limited to 'gcc/testsuite/g++.dg/other/packed1.C') diff --git a/gcc/testsuite/g++.dg/other/packed1.C b/gcc/testsuite/g++.dg/other/packed1.C new file mode 100644 index 000000000..ac586c6c0 --- /dev/null +++ b/gcc/testsuite/g++.dg/other/packed1.C @@ -0,0 +1,29 @@ +// { dg-do run { xfail sh-*-* lm32-*-* } } + +// NMS:2003-04-21 this fails on strict aligned architectures again, +// the patch was reverted because it broke something more important. + +// Copyright (C) 2002 Free Software Foundation, Inc. +// Contributed by Nathan Sidwell 8 Aug 2002 + +// WRS SPR 63496, lost packed attribute when accessing a packed +// field.
