// in safe mode correctly folds functions in a shared object. The

// foo_* functions below should not be folded.  For x86-64,

// foo_glob and bar_glob should be folded as their function pointers

// are addresses of PLT entries in shared objects.  For 32-bit X86,

// the hidden protected and internal symbols can be folded.
