Subject: [Bug c++/100700] -Wreturn-type has many false positives
Date: Sun, 23 May 2021 14:32:29 +0000	[thread overview]

--- Comment #7 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Right, and of course there are many -Wreturn-type cases where no switches or
enums are involved at all.

The warning is about the missing return from the end of the function, not about
the switch that happens before that. Determining that the end of the function
was reached because of a misunderstanding about how enumerations work (either
in the standard, or in GCC without -fstrict-enums) is probably not easy.
