@xazax.hun did you actually run the tool on the LLVM codebase?
Because this check generates **tons** of false-positive reports during codebase analysis.
See the minimal example below.
omtcyf0-laptop:playground omtcyf0$ cat main.cpp
#include <vector>
int main() {
std::vector<int> numbers = {1, 2, 3, 4, 5, 6};
for (std::vector<int>::const_iterator it = begin(numbers), end = end(numbers);
it != end; ++it) {
(*it)++;
}
return 0;
}
omtcyf0-laptop:playground omtcyf0$ /Users/omtcyf0/Documents/dev/build/Release/llvm/bin/clang-tidy -checks=misc-suspicious-semicolon main.cpp
Error while trying to load a compilation database:

/Users/omtcyf0/Documents/dev/playground/main.cpp:6:17: warning: potentially unintended semicolon [misc-suspicious-semicolon]
it != end; ++it) {
^
/usr/include/wchar.h:89:10: error: 'stdarg.h' file not found [clang-diagnostic-error]
#include <stdarg.h>
^
And this is happening all over the LLVM codebase, because there is nothing bad there.
Can you please fix that?
