如何将地址分配给标签？ winmips64

Question

一切都很好，直到我到达LW R9，0（R7），因为我没有标签的地址。我该如何制作，以便可以存储标签的地址并跳到标签上？

IM应该使其在WinMIPS64

//C code
switch (k){
          case 0: f = i + j; break ; /* k = 0*/
          case 1: f = g + h; break ; /* k = 1*/
          case 2: f = g - h; break ; /* k = 2*/
          case 3: f = i - j; break ; /* k = 3*/
          }

“理论” MIPS代码（不是实际的MIP）

    slt $t3, $s5, $zero   # $t3=1 if k < 0
    bne $t3, $zero , Exit # if k < 0 go to Done
    slt $t3, $s5, $t2     # Test if k < 4
    beq $t3, $zero , Exit # if k >= 4 go to Done

    add $t1, $s5, $s5
    add $t1, $t1, $t1

    #Assume Four sequential words in memory with the address in $t4 contain the 
    #addresses corresponding to the Labels L0,L1....

    add $t1, $t1, $t4 # $t1=address of JumpTable[k]
    lw $t0, 0($t1)     # $t1=JumpTable[k]

    jr $t0

    L0: add $s0, $s3, $s4  # f = i + j
       j Done
    L1: add $s0, $s1, $s2  # f = g + h
       j Done
    L2: sub $s0, $s3, $s4  # f = g - h
       j Done
    L3: sub $s0, $s1, $s2  # f = i - j
    Done:

中起作用，因为我使用的是WinMIPS64，

;r0 = $zero
;r1 = f s0
;r2 = h s2
;r3 = i s3
;r4 = j s4
;r5 = k s5
;r10 = g s1
;r6 = Temp1
;r7 = Temp2
;r8 = Temp3
;r9 = Temp4

    .data
f:      .word 0,0
h:  .word 0x00000010
i:  .word 0x00000000
j:  .word 0x00000000
k:  .word 0x00000010
Temp1:  .word 0x00000000
Temp2:  .word 0x00000000
Temp3:  .word 0x00000000
Temp4:  .word 0x00101000
g:      .word 0x00001000

    .text
start: jal SwitchCases   ; call subroutine
       nop
       halt

SwitchCases: 
         lw r1, f(r0)
         lw r2, h(r0)
         lw r3, i(r0)
         lw r4, j(r0)
         lw r5, k(r0)
         lw r6, Temp1(r0)
         lw r7, Temp2(r0)
         lw r8, Temp3(r0)
         lw r9, Temp4(r0)
         lw r10, g(r0)
         slt r6, r5, r0
         bne r6, r0, Exit
             slt r6, r5, r7
             beq r6, r0, Exit
             dadd r7, r5, r5
             dadd r7, r7, r7
         
         dadd r7, r7, r8
         lw r9, 0(r7)
         
             jr r9
             
L0:          dadd r1, r3, r4
             j Exit  
L1:          dadd r1, r10, r2
             j Exit
L2:          dsub r1, r3, r4
             j Exit
L3:          dsub r1, r10, r2
             j Exit
Exit:
        

因为先前的代码$ t1必须存储Jumptable [k]的地址。
