Note: jr is an R$-$type instruction with an opcode $(000000)$ and function field $(001000).$ For jr $ra instruction, rs field will hold $ ra$/$ $$31($i$.$e$.,11111)$ and other register $(rd$ and $rt)$ fields will hold $0($i$.$e$.,00000).$

$3.$ Show the MIPS instructions that implement the following pseudoinstructions.

$($a$)$ beq $$11,$ imm ${?}_{31\text{:}0},L$

$($b$)$ ror $$s4,$$$t6,31($rotate $$t6$ right by $31$ and put the result in $$s4)$

$($c$)$ bgt $$t3,$$$t5L($branch to address $L$ if $$t3$ is greater than $$t5)$

$($d$)$ bge $$t3,$$$t5L($branch to address $L$ if $$t3$ is greater than or equal to $$t5)$

$4.$ Fill the blanks where registers should be stored or retrieved to$/$from the stack according to the function call convention of the MIPS assembly.
