Consider the following Tiger code that gets converted to its MIPS assembly: function main()    begin        let            var a, i : int := 0;            var b : int := 1;        begin            a := a + b;            while (i < 10) do                a := a + b;                if (i < 5) then                    a := a + b;                else                    a := a - b;                endif;                a := a + b;                i := i + 1;            enddo;            printi(a);        end    end main:   addi $sp, $sp, __    li $t1, 0    li $s2, 0   li $t0, __    add $s2, $s2, $t0_L0:   li $t8, __   bge $t1, $t8, __    add $s2, $s2, $t0    li $t8, 5   bge $t1, $t8, _L2    add $s2, $s2, $t0   j ___L2:    sub $s2, $s2, $t0_L3:    add $s2, $s2, $t0   addi __, __, 1   j ___L1:    move $a0, $s2    li $v0, 1    syscall    li $a0, 10    li $v0, 11    syscall   addiu $sp, $sp, 40    jr $ra The MIPS assembly for the above code has some parts replaced with underline blanks. What values, temporary variables or labels need to be in these blanks?

Given L1 and L2  is a regular language, which of the following are regular languages?

Compilers, like programmers, can introduce inefficiencies while translating source language into IR. As a result, the compiler’s optimizer is very important in removing these inefficiencies. Give two examples of inefficiencies you would expect an optimizer to improve. Give two examples of inefficiencies you would expect an optimizer to miss, even though they can be improved. Explain why an optimizer would have difficulty improving them. (8 pts)
