I think this could be problematic when building a Clang without an X86 target, unless you also mark X86 REQUIRED (at least in the CodeGen tests). Would using cc1 and hardcoding --debug-info-kind=limited (or something like that) work, too?

I'm just going to revert cbd8ec93709376fbf404c99f4eee399790e26db7 and e486921fd6cf96ae9114adac455f7c0b5c1088a7 and sort this out on Monday.

Oh, sorry I didn't notice this in the original review - tests outside of test/Driver should only use %clang_cc1, rather than testing through the driver. Could you update this test and the C test to use %clang_cc1?

& why did this need a specific target triple? What did that change in the output?

It looks like maybe the/a bug is that the RETTYPES check has a hardcoded value in it (!5, in this test, !17 in the C test) - those should be removed, replaced with {{![0-9]*}} for instance. That might make these tests work without a specific triple, which would get us some more test coverage.
