在这个 MIPS 程序中
当这段代码片段运行时,一共会执行多少条指令?
i1: ori $t0, $0, 1000
i2: ori $t1, $0, 2000
i3: addi $t2, $t0, 100
i4: lw $t3, 0($t1)
i5: lw $t4, 0($t0)
i6: add $t3, $t3, $t4
i7: sra $t3, $t3, 1
i8: sw $t3, 0($t0)
i9: sw $t3, 0($t1)
i10: addi $t0, $t0, 4
i11: addi $t1, $t1, 4
i12: slt $t3, $t0, $t2
i13: bne $0, $t3, i4
