Bug ID: 33576
Summary: Libunwind needs a way to disable visibility
annotations [PATCH INCLUDED]
Product: libc++
Version: unspecified
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P

patch
libc++ and libc++abi both have _LIBCPP_DISABLE_VISIBILITY_ANNOTATIONS and
_LIBCXXABI_DISABLE_VISIBILITY_ANNOTATIONS respectively.
The same feature is needed for libunwind. This way, apps that statically link
libunwind can hide its symbols (otherwise libgcc will use the libunwind symbols
and crash).
