d: Warn when casting from a D class to a C++ class.
Before, the warning was only issued when casting in the other direction.
Now a warning is printed for both directions.
gcc/d/ChangeLog:
* d-convert.cc (convert_expr): Warn when casting from a D class to a
C++ class.
gcc/testsuite/ChangeLog:
* gdc.dg/Waddress.d: New test.
* gdc.dg/Wcastresult1.d: New test.
* gdc.dg/Wcastresult2.d: New test.
