But like @srhines said, doing this one function at a time is preferable but not always possible (or maybe we can wrap consecutive functions within the same pragma push/pop pair? I tried to verify but ran into error: attribute 'uninitialized' is not supported by '#pragma clang attribute), and automating it is more difficult. From this perspective, I think the proposed patch is complementary to pragma and not meant to replace it.


Right, support needs to be added, and I was wondering if you'd want to do this because it seems like a tool that would help you out.
