Friendly ping to everybody watching. I'd like to get this in soon if possible.

Hi All, I'm going on leave for two weeks, returning October 14th. I can plausibly respond to comments until 14:00 UTC tomorrow (Thu 25th Sept).

Thanks everyone for your comments.

• Fixed spurious comma
• Fixed incorrect comment and changed comment wrapping.

Updated comment for IsFlangMode.

Updated for review comments and spotted a couple of things myself.

Fixed assertion message "Input output." => "Invalid output". The erroneous text came was copied from: https://github.com/llvm/llvm-project/blob/6b9df910d04fae62dacc22c1c84f66c0f126cde0/clang/lib/Driver/ToolChains/Clang.cpp#L3849

I updated this "prototype" revision into the real thing I would like to submit. Please let me know if that was the wrong thing to do and I will resubmit it.

I do not have submit permissions, please can someone submit on my behalf?

Updated for code review comment.

Add target triple to test.

Include full context.

Note: In case you see this early, the email isn't yet sent to the list. I'll link it here when it is, likely tomorrow.
