#include<stdio.h>

unsigned long value1[2]={0x12a2e670,0xa2435649};
unsigned long value2[2]={0x12a2e670,0xa2435649};
unsigned long result[2];

unsigned long *a=&value1;
unsigned long *b=&value2;
unsigned long *c=&result;


main()
{
asm("ldr r0,%[v]\n\t"
                "ldr r1,[r0]\n\t"
                "ldr r2,[r0,#4]\n\t"
                ::[v] "r" (a));
asm volatile( "ldr r0,%0\n\t"
                "ldr r3,[r0]\n\t"
                "ldr r4,[r0,#4]\n\t"
                ::"r" (b):"memory");
asm volatile( "adds r6,r2,r4\n\t"
                "adc r5,r1,r3\n\t"
                "ldr r0,%0\n\t"
                "str r5,[r0]\n\t"
                "str r6,[r0,#4]\n\t"
                ::"r" (c):"memory");
