Analyze Statically Linked Binaries on Linux* Targets

To profile a statically linked binary file, temporary stop stripping the binary file during compilation and make sure the binary file exports the following symbols from system libraries:
  • _init()
     in the main executable: if you profile a tree of processes, consider using the option.
  • libc.so
    :
    • A target exports
      setenv
      ,
      getenv()
      , and
      __errno_location()
       symbols unconditionally.
    • If a target employs
      recv()
      API, it exports
      recv()
       and
      poll()
      .
    • If a target employs
      sleep()
       or
      usleep()
       APIs, it exports
      sleep()
       or
      usleep()
       respectively, and
      nanosleep()
       symbol.
  • libpthread.so
    :
    • If a target employs
      pthread_create()
       API, it exports the following symbols:
      • pthread_create()
      • pthread_key_create()
      • pthread_setspecific()
      • pthread_getspecific()
      • pthread_self()
      • pthread_getattr_np()
      • pthread_attr_destroy()
      • pthread_attr_setstack()
      • pthread_attr_getstack()
      • pthread_attr_getstacksize()
      • pthread_attr_setstacksize()
      • If a target employs
        pthread_cancel()
         API, it exports the following symbols:
        • pthread_cancel()
        • _pthread_cleanup_push()
        • _pthread_cleanup_pop()
      • If a target employs
        _pthread_cleanup_push()
         or
        _pthread_cleanup_pop()
         API, it exports the following symbols:
        • _pthread_cleanup_push()
        • _pthread_cleanup_pop()
      • If a target employs
        pthread_mutex_lock()
         API, it exports
        pthread_mutex_lock()
         and
        pthread_mutex_trylock()
         symbol.
      • If a target employs
        pthread_spin_lock()
         API, it exports
        pthread_spin_lock()
         and
        pthread_spin_trylock()
         symbol.
  • libdl.so
    :
    If a target employs any of
    dlopen()
    ,
    dlsym()
    , or
    dlclose()
     APIs, it exports all three of them simultaneously.
If the binary file does not export some of the symbols above, use the
-u
 linker switch (for example, specify
-Wl,-u__errno_location
 if you use compiler for linking) to include symbols into the binary file at the linking stage of compilation.
