high level language translation into mips

hey,
i am new to mips and have been trying to translate a quicksort algorithm into mips. problem is that when i load it into PCSpim, it gets hung up and just continues to run until I close Spim. can anyone look at what I have and see if you can figure out where its getting hung up?
Oh and i didnt comment it yet.
.data
array: .word 8,2,7,1,5,6,3,4,9,0
length: .word 10
.text
.globl main

main:
la $a0, array
move $a1, $zero
lw $a2, length
sub $a2, $a2, 1
jal QuickSort

li $v0, 10
syscall

Hi

If you already have a hi-level program so you don't need to translate it into mips assembly

just use MIPS gcc compiler.
you may face some compiling errors but it could be overcome

if you need the aeembly to simulate over SPIM just set GCC to generate assembly code

that is:

mips-elf-gcc -S -mips1

you can use these options.
but the assembly code will not contain the "syscall" statements. It will contain actual calls to libc primitives (i think).

it seems that you want to interpret and simulate your assembly file with spim.
