            Bug ID: 46709
           Summary: LIBUNWIND_HERMETIC_STATIC_LIBRARY: unw_getcontext
                    isn't hidden
           Product: Runtime Libraries
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: libunwind
          Assignee: unassignedbugs at nondot.org
          Reporter: rprichard at google.com
                CC: llvm-bugs at lists.llvm.org

The LIBUNWIND_HERMETIC_STATIC_LIBRARY flag marks the libunwind APIs as hidden,
so they aren't exported from an executable or shared object. CMake passes
-fvisibility=hidden to the compiler and defines
_LIBUNWIND_DISABLE_VISIBILITY_ANNOTATIONS to disable explicit visibility
attributes on individual functions.

The flag doesn't apply to unw_getcontext, though, which is declared in assembly
(UnwindRegistersSave.S).
