@thakis believes the problem was the lack of -n on my llvm-cxxfilt call,
so hopefully this is the only problem. Committing to see if this makes
all the buildbots happy.
AND the followups that fixed builds.
I attempted to get 'cute' and use llvm-cxxfilt to make the test look
nicer, but apparently some of the bots have a version of llvm-cxxfilt
that is not the in-tree one, so it fails to properly demangle the stuff.
I've disabled this "RUN" line.
This reverts commit 50186b63d1.
As reported in https://github.com/llvm/llvm-project/issues/54588
and discussed in https://github.com/itanium-cxx-abi/cxx-abi/issues/139
We are supposed to do a DFS, pre-order, decl-order search for a name for
the union in this case. Prevoiusly we crashed because the IdentiferInfo
pointer was nullptr, so this makes sure we have a name in the cases
described by the ABI.
I added an llvm-unreachable to cover an unexpected case at the end of
the new function with information/reference to the ABI in case we come
up with some way to get back to here.
