以mips方式循环和访问数组

Question

我正在尝试遍历数组并找到最大值（int）然后打印出该值。使用下面的代码我得到一个运行时错误，说

＆＃34;在pc = 0x00400034

时发生异常

inst / data fetch中的未对齐地址：0x10010001

尝试在0x80000180＆＃34;

执行非指令

.globl __start
.data
purchases:  .word 5,10,15,20,25,7
.text

__start:
li $t1, 0 # the "i" variable
li $t2, 6 # amount of elements in the array
lw $t0 , purchases+0  #Read the value of the element [0] into $t0
j For_loop

print_int:
li $v0, 1 
syscall
li $v0, 10 
syscall

For_loop:
blt $t2,$t1,End_loop
lw $t4, purchases($t1)
ble $t0 , $t4, True
add $t1, $t1, 1           #Increment
j For_loop

True:
lw $t0 , purchases($t1)
add $t1, $t1, 1    #Increment
j For_loop         #loop

End_loop:
move $a0, $t0 
j print_int

li $v0, 10
syscall 

感谢所有反馈！
