--- Comment #2 from Marek Polacek <mpolacek at gcc dot gnu.org> ---
As for the doc, I'll do it.

But note that -fsanitize=return and -fsanitize=use-after-return are two
different options: -fsanitize=return is a part of ubsan and checks that the
function doesn't have a missing "return" statement (currently done only for
C++).
-fsanitize=use-after-return is described in the link you provided and is a part
of asan.
