int main(void) {
unsigned long long a = 0x0ab0000000234432;
unsigned long long b = 0x0000000000000001;
unsigned long long c = 0x0000000032123001;
unsigned long long r1;

__asm__ __volatile__(
    "mov    %1, %%eax   \n\t"
    "xor    %2, %%eax   \n\t"
    "xor    %3, %%eax   "

    : "g" (a), "g" (b), "g"(c));

for(i=63; i>=0; i--) {
    printf("%d ", (r1 >> i) & 1 );
    if (i%8 == 0) printf(" ");
}
printf("\n");
return 0;
}

二进制值是
a = 00001010 10110000 00000000 00000000 00000000 00100011 …
