--- Comment #3 from Reid Kleckner <rnk at google.com> ---
This appears to be fixed. I used this code to check:

#include <inttypes.h>
#include <stdio.h>
#include <stdlib.h>

#define FOO(_a) \
    (((_a) > 63 && (_a) < 128 ? (((uint64_t) 1)<<((_a)-64)) : (uint64_t) 0))

int
main(int argc, char *argv[])
{
        printf("%"PRIx64"\n", FOO(argc));

        printf("%"PRIx64"\n", FOO(1));

        return EXIT_SUCCESS;
}


Today I get this:

$ clang -c -Weverything clang-shift.c  -Werror
clang-shift.c:9:22: error: unused parameter 'argv' [-Werror,-Wunused-parameter]
main(int argc, char *argv[])
                     ^
1 error generated.
