<p>In a way that is what is slowly happening. With C++17 there will be a <a href="https://en.cppreference.com/w/cpp/language/attributes/fallthrough" class="remarkup-link" target="_blank" rel="noreferrer">standardized</a> attribute <tt style="background: #ebebeb; font-size: 13px;">[[fallthrough]]</tt> and I suspect that <tt style="background: #ebebeb; font-size: 13px;">-Wfallthrough</tt> will become a standard warning like <tt style="background: #ebebeb; font-size: 13px;">-Wreturn-type</tt> by then. (The latter warns if some code paths in a function don't return a value, as in <tt style="background: #ebebeb; font-size: 13px;">int f() {}</tt>.) As for Qt, there is of course <tt style="background: #ebebeb; font-size: 13px;">Q_FALLTHROUGH()</tt> in <tt style="background: #ebebeb; font-size: 13px;">qcompilerdetection.h</tt>, which chooses one of <tt style="background: #ebebeb; font-size: 13px;">[[{,gnu::,clang::}fallthrough]]</tt>, depending on which is available.</p>
<p>With that attribute fallthroughs can be annotated, so the compiler can easily warn if a <tt style="background: #ebebeb; font-size: 13px;">break</tt> statement is missing. When there is a false positive, it can easily be fixed by adding the attribute.</p></div></div><br /><div><strong>REPOSITORY</strong><div><div>R32 KDevelop</div></div></div><br /><div><strong>REVISION DETAIL</strong><div><a href="https://phabricator.kde.org/D15532">https://phabricator.kde.org/D15532</a></div></div><br /><div><strong>To: </strong>rjvbb, KDevelop, kossebau, kfunk<br /><strong>Cc: </strong>aaronpuchert, kfunk, pino, kossebau, kdevelop-devel, glebaccon, antismap, iodelay, vbspam, geetamc, Pilzschaf, akshaydeo, surgenight, arrowd<br /></div>
