实例1:

求1+2+3+......+100的和, 并将结果存入0x80000100地址空间中.

 1     area text, code, readonly
 2     entry
 3     code32
 4 start
 5     mov r1, #0
 6     mov r2, #100
 7 loop
 8     add r3, r3, r1 ;累加
 9     add r1, r1, #1 ;自增
10     cmp r1, r2
11     ble loop
12     ldr r2, =0x80000100
13     str r3, [r2]   ;保存结果
14     nop
