A small testcase:
[hjl@gnu-16 bld]$ cat x.c
#include <ctype.h>
#if ((' ' & 0x0FF) == 0x020)
# define ISLOWER(c) ('a' <= (c) && (c) <= 'z')
# define TOUPPER(c) (ISLOWER(c) ? 'A' + ((c) - 'a') : (c))
#else
# define ISLOWER(c) (('a' <= (c) && (c) <= 'i') ||
('j' <= (c) && (c) <= 'r') || ('s' <= (c) && (c) <= 'z'))
# define TOUPPER(c) (ISLOWER(c) ? ((c) | 0x40) : (c))
#endif
#define XOR(e, f) (((e) && !(f)) || (!(e) && (f)))
int
main ()
{
int i;
for (i = 0; i < 256; i++)
if (XOR (islower (i), ISLOWER (i))
|| toupper (i) != TOUPPER (i))
return 2;
return 0;
}
[hjl@gnu-16 bld]$ gcc -g -O2 -c -fprofile-use x.c
