Subject: Feature request: typeof_unqual keyword support
Date: Tue, 13 Aug 2024 08:33:45 +0200 [thread overview]
Message-ID: <CAFULd4a70uMBT0mby98ocEUy3OiA1U83a9zB+qHmq-eY7AkuTw@mail.gmail.com> (raw)
Hello!
C23 introduced a new typeof operator, typeof_unqual [1], same as
typeof, but removes qualifiers. gcc-14 [2] and clang (19?) also
introduced __typeof_unqual__ and __typeof_unqual alternate spelling,
available in all C modes.
A recent kernel patch [3] would like to introduce __typeof_unqual__ to
kernel sources. Since this keyword is not known to the sparse checker,
it breaks C=1 checking.
It would be nice if sparse supports this new keyword and its alternate
spellings.

Thanks,
Uros.
