New Revision: 187393
URL: http://llvm.org/viewvc/llvm-project?rev=187393&view=rev
Log:
Fix a truly egregious thinko in anonymous namespace check,
update testcase to make sure we generate debug info for walrus
by adding a non-trivial constructor and verify that we don't
emit an ODR signature for the type.
