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. Signed-off-by: Joshua Watt <[email protected]>
