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/warn/weak1.C | 22 ++++++++++++++++++++++ 1 file changed, 22 insertions(+) create mode 100644 gcc/testsuite/g++.dg/warn/weak1.C (limited to 'gcc/testsuite/g++.dg/warn/weak1.C') diff --git a/gcc/testsuite/g++.dg/warn/weak1.C b/gcc/testsuite/g++.dg/warn/weak1.C new file mode 100644 index 000000000..8a50030bc --- /dev/null +++ b/gcc/testsuite/g++.dg/warn/weak1.C @@ -0,0 +1,22 @@ +// { dg-do run } +// { dg-require-weak "" } +// The PA HP-UX and Tru64 UNIX dynamic loaders don't support unsatisfied +// weak symbols. +// { dg-skip-if "No unsat" { alpha*-dec-osf* hppa*-*-hpux* } { "*" } { "" } } +// The darwin loader does, but they do need to exist at link time. +// { dg-skip-if "No link unsat" { *-*-darwin* } { "*" } { "" } } +// For kernel modules and static RTPs, the loader treats undefined weak +// symbols in the same way as undefined strong symbols.
