From 76c37f74890359c96ff8da16749bfecd3562313d Mon Sep 17 00:00:00 2001 From: "Gustavo A. R. Silva" Date: Thu, 7 Mar 2019 16:28:25 -0800 Subject: [PATCH] lib/assoc_array.c: mark expected switch fall-through In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through. This patch fixes the following warning: lib/assoc_array.c: In function `assoc_array_delete': lib/assoc_array.c:1110:3: warning: this statement may fall through [-Wimplicit-fallthrough=] for (slot = 0; slot < ASSOC_ARRAY_FAN_OUT; slot++) { ^~~ lib/assoc_array.c:1118:2: note: here case assoc_array_walk_tree_empty: ^~~~ Warning level 3 was used: -Wimplicit-fallthrough=3 This patch is part of the ongoing efforts to enable -Wimplicit-fallthrough.
