From: "j.wuttke@fz-juelich.de" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug c++/112309] New: enhancement: extra flags to let -Wshadow skip if..else and lambda blocks Date: Tue, 31 Oct 2023 10:48:21 +0000 [thread overview] Message-ID: <bug-112309-4@http.gcc.gnu.org/bugzilla/> (raw) https://gcc.gnu.org/bugzilla/show_bug.cgi?id=112309 Bug ID: 112309 Summary: enhancement: extra flags to let -Wshadow skip if..else and lambda blocks Product: gcc Version: 14.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ Assignee: unassigned at gcc dot gnu.org Reporter: j.wuttke@fz-juelich.de Target Milestone: --- Suggestion: add a flag -Wnoshadow-ifelse to prevent -Wshadow from reporting shadowing in "else if" constructs like if (auto* p = dynamic_cast<A>(x)) ... else if (auto* p = dynamic_cast<B>(x)) ... else if (auto* p = dynamic_cast<C>(x)) ... A similar approach (-Wnoshadow-lambda) could help to resolve https://gcc.gnu.org/bugzilla/show_bug.cgi?id=79328.
