/* Compile with:
   clang -g -c  odr-uniquing.cpp -o odr-uniquing/1.o
   cp odr-uniquing/1.o odr-uniquing/2.o
   The aim of these test is to check that all the 'type types' that
   should be uniqued through the ODR really are.

   The resulting object file is linked against itself using a fake
   debug map. The end result is:
    - with ODR uniquing: all types in second and third CUs should point back
   to the types of the first CU(except types from anonymous namespace).
    - without ODR uniquing: all types are re-emited in the second CU.
