A better example as on 32bit targets long and int are the same size which
removes the casts:
extern long long int llabs (long long int __x) __attribute__ ((__const__));
int main()
{
int a,b;
foo(&a, &b);
if (llabs(a) > b)
return 1;
else
return 0;
}
Or just as good:
extern int abs (int __x) __attribute__ ((__const__));
void foo(short *, short*);
int main()
{
short a,b;
foo(&a, &b);
if (abs(a) > b)
return 1;
else
return 0;
}
Though only the first one will have different asm and will be better optimized.
