--- Comment #2 from Eric Gallager <egallager at gcc dot gnu.org> ---
As a user, I don't know if this is really something I'd expect
-Wduplicated-cond to warn about; my impression was that that was for when the
programmer literally writes the same condition twice, not when the compiler is
being smart and figures out conditions are redundant via VRP or whatever... I
mean, -Wduplicated-cond prints "previously used here" notes; where would that
point in this case? The covered condition is covered by 2 separate previous
conditions; would both get notes? I think this warning would make more sense as
part of -Wtautological-compare or -Wlogical-op instead, or as part of a revival
of -Wunreachable-code, in which case this would be related to (or a dup of) bug
