Consider the following lines of code that represent a MIPS procedure func. For this question, we do not care about the functionality of func. Our goal is to make sure func follows the conventions of MIPS procedure calls. Assume that func uses Sa0 as input and returns the output in $v0. Add as many lines of MIPS code as you need to complete this function. Do not put unnecessary data on the stack. There may be more than one correct answer. Use the provided callouts to insert your MIPS instructions. Some callouts may be left empty. func: addi $a0, $a0, -1 addi $v0, 90, 1 ble $a0, $0, END add $80, $a0, $a0 sub $t0,$50, $50 jal func add $s0, $v0, $t0 addi $a0, $v0, $50 END: jr fra
