   1 /* Compile with:
   2    clang -g -c  odr-uniquing.cpp -o odr-uniquing/1.o
   3    cp odr-uniquing/1.o odr-uniquing/2.o
   4    The aim of these test is to check that all the 'type types' that
   5    should be uniqued through the ODR really are.
   6
   7    The resulting object file is linked against itself using a fake
   8    debug map. The end result is:
   9     - with ODR uniquing: all types in second and third CUs should point back
  10    to the types of the first CU(except types from anonymous namespace).
  11     - without ODR uniquing: all types are re-emited in the second CU.
