Consider this file:
```
#include <_types/_uint32_t.h>
enum class test_enum : uint32_t {
val1 = 0,
val2 = 1
};
static test_enum getVal() {
return test_enum::val1;
}
int main() {
auto v = getVal();
switch(v) {
case test_enum::val1:
return 1;
case test_enum::val2:
return 2;
}
return 0;
}
```
Run this file with clang-tidy 18.1.5 with `-checks=clang` and this error is reported:
`error: 'switch' missing 'default' label [clang-diagnostic-switch-default]`
but adding a default label will cause this error:
`error: default label in switch which covers all enumeration values [clang-diagnostic-covered-switch-default]`
It seems like you can't make clang-tidy happy either way.
Clang-tidy version: Homebrew LLVM version 18.1.5. Optimized build.
Platform: MacOS 14.1, Apple M3 Pro
