            Bug ID: 35066
           Summary: Clang never gives hidden visibility to fundamental
                    types, even with -fvisibility=hidden
           Product: clang
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++
          Assignee: unassignedclangbugs at nondot.org
          Reporter: thomasanderson at google.com

__cxxabiv1::__fundamental_type_info is a special class that causes the compiler
to generate type info for fundamental types (void, bool, char, ..).  When
building with -fvisibility=hidden, the __fundamental_type_info class itself is
given hidden visibility, but the generated types do not.
