From 4c33a3aaa38c94b103c51aa6a5553a4b1355c435 Mon Sep 17 00:00:00 2001 From: Jacob Garber Date: Fri, 12 Jul 2019 10:34:06 -0600 Subject: src: Make implicit fall throughs explicit Implicit fall throughs are a perpetual source of bugs and Coverity Scan issues, so let's squash them once and for all. GCC can flag implicit fall throughs using the -Wimplicit-fallthrough warning, and this should ensure no more enter the code base. However, many fall throughs are intentional, and we can use the following comment style to have GCC suppress the warning. switch (x) { case 1: y += 1; /* fall through */ case 2: y += 2; /* fall through - but this time with an explanation */ default: y += 3; } This patch adds comments for all remaining intentional fall throughs, and tweaks some existing fall through comments to fit the syntax that GCC expects.
