[llvm-commits] What requires __debug_frame?

[Rafael Avila de Espindola]

I was wondering what software requires __debug_frame. I decided to try 
changing the default and see what would break. Surprisingly, it was just 
a a single test that I needed to update to expect cfi directives.

I used a clang modified with the attached patch to build a debug version 
of clang itself and gdb is happy with it. I can set breakpoints, get 
backtraces, etc.

So, is __debug_frame just an historical thing right now?

Thanks,
Rafael
