[cfe-commits] [Patch] Warn about self-initialization of reference variables

[Hans Wennborg]

Hi all,

The attached patch makes Clang warn about self-initialization of
references, like:

  int &a = a;

Because that seems like a bad thing to do, and I don't think we should
suppress it like we do with "int x = x" which is a common way of
avoiding warnings about unused variables.

Please take a look.

Thanks,
Hans
