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/visibility/arm3.C | 36 ++++++++++++++++++++++++++++++ 1 file changed, 36 insertions(+) create mode 100644 gcc/testsuite/g++.dg/ext/visibility/arm3.C (limited to 'gcc/testsuite/g++.dg/ext/visibility/arm3.C') diff --git a/gcc/testsuite/g++.dg/ext/visibility/arm3.C b/gcc/testsuite/g++.dg/ext/visibility/arm3.C new file mode 100644 index 000000000..9be7082ce --- /dev/null +++ b/gcc/testsuite/g++.dg/ext/visibility/arm3.C @@ -0,0 +1,36 @@ +// { dg-do compile { target arm*-*-*eabi* } } +// { dg-require-dll "" } +// { dg-options "-fvisibility=hidden" } + +/* From ARM C++ ABI \S 3.2.5.5: + + A class should be exported unless explicitly tagged otherwise. + + This admonition applies even on DLL-based systems where hidden + visibility is the default.
