<pre>clang version 6.0.0 (trunk 317263)
This code:
int main(int argc, char** argv) {
if (argc > 4); // <-- Note semicolon!
return 0;
}
Gives:
eraseme.cc:2:16: warning: if statement has empty body [-Wempty-body]
if (argc > 4);
^
eraseme.cc:2:16: note: put the semicolon on a separate line to silence this
warning
1 warning generated.
This is good! And it also works for "else if" cases. But I just did the same
bug and put a semicolon after a bare else:
int main(int argc, char** argv) {
if (argc > 4)
return 1;
else; // <- Semicolon
return 2;
return 0;
}
And there is no warning. This was pretty tricky to find and it seems like the
same rule for "if" semicolons should just also be applied to "else".</pre>
