Question

The following code is in MIPS. How would it be converted into RISC-V?

main:
    la  $t0, Array      # Copy the base address of your array into $t1
    add $t0, $t0, 40    # 4 bytes per int * 10 ints = 40 bytes                              
outterLoop:             # Used to determine when we are done iterating over the Array
    add $t1, $0, $0     # $t1 holds a flag 
    la  $a0, Array      # Set $a0 to the base address of the Array
innerLoop:                  # The inner loop will iterate 
    lw  $t2, 0($a0)         # sets $t0 to the current element in array
    lw  $t3, 4($a0)         # sets $t1 to the next element in array
    slt $t5, $t2, $t3       # $t5 = 1 if $t0 < $t1
    beq $t5, $0, continue   
    add $t1, $0, 1          
    sw  $t2, 4($a0)         
    sw  $t3, 0($a0)         
continue:
    addi $a0, $a0, 4            
    bne  $a0, $t0, innerLoop   
    bne  $t1, $0, outterLoop

RISC-V program :-

.text
.global main
main:
push {r4-r10, lr}
mov r1, #10

outterLoop:
mov r10, #0
sub r1, #1 @ Decrement Counter for loop

   ldr r0, =Array
   mov r4, #1
  
   innerLoop:
       ldr r5, [r0]
       ldr r7, [r0, #4]
       cmp r5, r7
       ble continue
       strgt r7, [r0]
       strgt r5, [r0, #4]
       add r10, #1
   continue:
       add r0, #4
       cmp r4, r1
       add r4, #1
       blt innerLoop

   cmp r10, #0
   bne outterLoop

exit:
pop {r4-r10, lr}
mov r0, #0
bx lr
