[PATCH] D62868: [libc++] Always build with -fvisibility=hidden

[Peter Smith via Phabricator via llvm-commits]

peter.smith added a comment.

Apologies for the late notice, we've just moved one our builders http://lab.llvm.org:8011/builders/libcxx-libcxxabi-libunwind-armv7-linux-noexceptions to use gcc rather than clang and we've just picked up some test failures due to this change. In summary when compiling libc++ with GCC the shared object defines a symbol as hidden that clang does not which is causing test failures due to linker errors. I've put the details in https://bugs.llvm.org/show_bug.cgi?id=43140 . It looks like the failure was first seen on http://lab.llvm.org:8011/builders/libcxx-libcxxabi-x86_64-linux-ubuntu-gcc5-cxx11/builds/345 (not run by us).
