 """Dump functions called by static intializers in a Linux Release binary.
 
 Usage example:
   tools/linux/dump-static-intializers.py out/Release/chrome
 
 A brief overview of static initialization:
 1) the compiler writes out, per object file, a function that contains
    the static intializers for that file.
 2) the compiler also writes out a pointer to that function in a special
    section.
 3) at link time, the linker concatenates the function pointer sections
    into a single list of all initializers.
 4) at run time, on startup the binary runs all function pointers.
 
 The functions in (1) all have mangled names of the form
   _GLOBAL__I_foobar.cc
 using objdump, we can disassemble those functions and dump all symbols that
 they reference.
