--- Comment #1 from David Binderman <dcb314 at hotmail dot com> ---
Interestingly, I tried a build of gcc trunk with the new clang-14
and got many cases of this warning.
$ grep "warning:.*Wbitwise-instead-of-logical" mk.out | sort | uniq -c > /tmp/0
$ wc -l /tmp/0
16 /tmp/0
$ cat /tmp/0

On the evidence of the source code of gcc, this new clang warning
might be worth implementing in gcc.
