Non-portable test?

[Yuri Gribov]

Hi all,

This is my first post to the list so do not be too harsh)

I have expected all c-torture tests to be highly portable but I have
recently ran into test which relies on int being 32-bit
(execute/980526-2.c).

The test runs to_kdev_t(0x12345678) (see below) and verifies that
result equals 0x15800078. But this is true only with 32-bit ints. With
64-bits we have 0x48d15800078.

static inline kdev_t to_kdev_t(int dev)
{
   int major, minor;

   if (sizeof(kdev_t) == 16)
       return (kdev_t)dev;
   major = (dev >> 8);
   minor = (dev & 0xff);
   return ((( major ) << 22 ) | (  minor )) ;
}

Shouldn't we modify a precondition in main:
   if (sizeof (int) < 4)
     exit (0);
to be
   if (sizeof (int) != 4)
     exit (0);
or better
   if( sizeof(int)*CHAR_BIT != 32 )
     exit(0)
?

Best regards,
Yuri
