From 475bf707b958f37844534b7b45c905521c7401a2 Mon Sep 17 00:00:00 2001 From: David Oberhollenzer Date: Thu, 21 Sep 2017 11:15:32 +0200 Subject: Mark or fix switch cases that fall through Now that C++17 introduced a special fallthrough keyword for explicitly tagging switch cases that are supposed to fall through, newer gcc versions also implement a feature request from 2002 to warn about maybe unwanted fall-throughs in switch cases in other languages (like C). For C code, we can either add a gcc specific attribute at the end of the switch case, or use a special comment that gcc checks for, indicating that the fall-through behaviour is indeed intended. This patch adds a "/* fall-through */" comment at the end of various case blocks to silence gcc warnings and in some cases a break, where fall-through was probably not intended.
