it's great for the used/unused labels.
It won't work for this:
void a(int i){
if (i) got out;
printf("hi\n");
out:
}
the out:
}
is not legal, for reasons I don't agree with, but ...
a.c:4:1: error: label at end of compound statement
one way to fix it:
out:
return;
}
but it's not really right:
void a(int i){
if (i) {goto out; bad:}
printf("hi\n");
out:
return;
}
line 2 will get an error.
