From 555e15ebe8bf1eb33d00747173cfc80cc65648a4 Mon Sep 17 00:00:00 2001 From: Joshua Watt Date: Fri, 9 Feb 2018 10:27:18 -0600 Subject: Use fallthrough attribute. Use __attribute__ ((fallthrough)) to indicate switch case fall through instead of a comment. This ensures that the fallthrough warning is not triggered even if the file is pre-processed (hence stripping the comments) before it is compiled. The actual fallback implementation is hidden behind a FALLBACK macro in case the compiler doesn't support it. Finally, the -Wimplict-fallthrough warning was upgraded to only allow the attribute to satisfy it; a comment alone is no longer sufficient.
