/* 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 (expect for the union for now) in
|
|
the second CU should point back to the types of the first CU.
|
|
- without ODR uniquing: all types are re-emited in the second CU
|
