This diagnostic rule is based on the software development guidelines developed by MISRA (Motor Industry Software Reliability Association).
The use of a 'goto' statement that jumps to a previously declared label obscures the code and, therefore, makes it harder to maintain.
Here is an example of code that will trigger this warning:
void init(....)
{
....
again:
....
if (....)
if (....)
goto again;
....
}To eliminate the warning, delete the 'goto' statement or rewrite the code so that the 'goto' statement is followed, rather than preceded, by the label it refers to.
