Oh, indeed. I had through that intptr_t and uintptr_t support normal 128-bit
integer arithmetic, but this is not the case:
================================================================================
#include <stdio.h>
#include <stdint.h>
int main ()
{
uintptr_t x;
intptr_t y;
int i;
printf ("sizeof = %d %d\n", (int) sizeof (uintptr_t), (int) sizeof
(intptr_t));
for (i = 0; i < 128; i++)
{
x = (uintptr_t)1 << i;
printf ("(uintptr_t)1 << %d = 0x%016lx%016lx = 0x%016lx%016lx\n", i,
(unsigned long)(x >> 64), (unsigned long) x,
(unsigned long)(x >> 32 >> 32), (unsigned long) x);
}
for (i = 0; i < 127; i++)
{
y = (intptr_t)1 << i;
printf ("(intptr_t)1 << %d = 0x%016lx%016lx = 0x%016lx%016lx\n", i,
(long)(y >> 64), (unsigned long) y,
(long)(y >> 32 >> 32), (unsigned long) y);
}
}
================================================================================
