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: unassignedb...@nondot.org
Reporter: rprich...@google.com
CC: llvm-bugs@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).
