--- Comment #4 from Uroš Bizjak <ubizjak at gmail dot com> ---
Something is wrong in [printf added by me]:
static int
check_sword2dword ()
{
int i, j, s, t, check_fails = 0;
for (i = 0; i < (NUM * 8); i = i + 8)
{
for (j = 0; j < 4; j++)
{
t = i + (2 * j);
s = (i / 2) + j;
printf ("%i %i %i %i\n", i, j, s, t);
res.li[s] = src1.si[t] - src1.si[t + 1] ;
if (res.li[s] != dst.li[s])
check_fails++;
}
}
}
gcc -O2 -msse -m32
$ ./a.out

i and j should start from 0.
