Code generation for expressions.Generate CMA code for the following expressions:

a 2(c+(b3)) b b (a + 3)

Assume the following address environment:

= {a 5, b 6, c 7}

Execute the generated code by displaying the stack contents after each instruction! Assume that the variables are initialised with the values a = 22, b = 33 and c =44.

Code generation for loops.Generate CMA code for the two loops:

while (x > y) {if (2 y > x) y y + x; else x x y;

}for (x 0; x < 42; x x + z)

if ((x = y))z z + 1; Use the following address environment:

= {x 2, y 3, z 5}

Code generation for statement sequences. Consider the following sequence of statements:

z 1;while (n > 0) {

j 1;y x;while (2 j n) {

y y y;

j j 2; }

z y z;

n n j; }

What does this statement sequence compute?

Translate the statement sequence into CMA code! Use the following address environment:

= {n 1, j 2, x 3, y 4, z 5}
