<pre>Ah, OK, I see better now - thanks for the sample.
Yes, I believe this is by design and the explicit (and only) intent of r265876.
Once a function is optimized away entirely, we will no longer generate debug
info for it (as of r265876).
Normal member functions will remain in a type - but implicit special members
and member function template specializations are special in a way. To talk
about member function template specializations: The set is unbounded, so the
absence of debug info for such a specialization doesn't mean one isn't present
in another translation unit, etc. So there's not much point generating debug
info for it.
Once a function is optimized away, we should produce debug info as if it were
never there/never generated. That's the goal & I think this patch brought us
much closer to that - though I forget/not sure how close we were before this
patch.</pre>
