C到MIPS转换。数组加载字偏移？

我有一个C代码，在MIPS中需要帮助。C代码如下所示

for (i=0; i<100; i++){
   a[i] = b[i] + c[i] - d[i];
}

对于（i=0；i阵列以内存中最低的基址排列，并以4字节的偏移量索引到下一个元素。[来自Harris D.M.，Harris S.L.的图像-数字设计和计算机架构，第二版-2012]


用于_循环：
bgt$t0，100，对于_loop_done#i，您可以按每个循环一个数组项的大小递增s0、s1、s2…或者复制它们并递增它们，这样您就不会丢失原始的起始地址。这适用于大多数指令集，包括此指令集。
addi $t0, $zero, 0                #i = 0

for_loop:
   bgt $t0, 100, for_loop_done     #i <100
   addi $t0, $t0, 1               #i++ or i = i+1


   lw $t4, __($s0)              # load a in t4
   lw $t1, __($s1)              # load b in t1
   lw $t2, __($s2)              # load c in t2
   add $t4, $t2, $t1                 # add b with c and store in a
   lw $t3, __($s3)              # load d in t3
   sub $t4, $t3, $t4                 # sub contents of a from d
   sw $t4, __($s0)              # store contents of t4 into a

   j for_loop                     # go to start of loop

for_loop_done:

 for_loop:
         bgt $t0, 100, for_loop_done     #i <100
         addi $t0, $t0, 1               #i++ or i = i+1


         lw $t4, 0($s0)              # load a in t4
         lw $t1, 4($s1)              # load b in t1
         lw $t2, 8($s2)              # load c in t2
         add $t4, $t2, $t1            # add b with c and store in a
         lw $t3, 12($s3)              # load d in t3
         sub $t4, $t3, $t4            # sub contents of a from d
         sw $t4, 0($s0)              # store contents of t4 into a

         j for_loop                   # go to start of loop
