population of libstdc++-v3/libsupc++/fundamental_type_info.o

[Korisk]

Hello!
File fundamental_type_info.o comprises symbols of typeinfo for fundamental types (typeinfo of int, typeinfo of char ... etc).
Source file (libstdc++-v3/libsupc++/fundamental_type_info.cc) contains a small piece of code:
 #include "tinfo.h"
 namespace __cxxabiv1 {
  __fundamental_type_info::
 ~__fundamental_type_info ()
 {}
 }
Compilation command for the source file doesn´t contain any unusual options.

So the question:
How fundamental_type_info.o is populated with symbols? Any hints or suggestions would be helpful.

Thank you.
