Subject: [Bug c++/46476] Missing Warning about unreachable code after return [-Wunreachable-code-return]

--- Comment #23 from Richard Biener <rguenth at gcc dot gnu.org> ---
Created attachment 51877
  --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=51877&action=edit
some fallout in GCC

This fixes some fallout appearant when bootstrapping with the patch, mostly
style, so not pushed to trunk.

There are more unresolved -Werror cases because of the change so I'm not sure
that warning at CFG construction is good enough for a narrow scope warning.

Instead the summary requested stmt after return could likely be implemented
at parsing time without too much hassle (but obviously repeated in every
frontend).
