GCC7 adds -Wimplicit-fallthrough to warn when a switch case falls through,
|
|
however this causes warnings (which are promoted to errors) with the elfutils
|
|
patches from Debian for mips and parisc, which use fallthrough's by design.
|
|
|
|
Explicitly mark the intentional fallthrough switch cases with a comment to
|
|
disable the warnings where the fallthrough behaviour is desired.
