Can someone please answer the following three questions (from 1 to 3)?

48 2 Imperative Programming Languages potentials offered by their architectures. One problem is to optimally make use of the register file of the target machine. Such problems will also be addressed in Volume 4. 2.11 Exercises 1. Code generation for expressions. Generate CMA code for the following expressions: a 2.(c +(5-3)) b- b. (a +3) Assume the following address environment: p= {a 5, 6,CH7} Execute the generated code by displaying the stack contents after each instruc- tion! Assume that the variables are initialized with the values a = 22, b= 33 and c = 44. 2. Code generation for loops. Generate CMA code for the two loops: while (x > y) { if (2.y > x) y + else x + x - y; y + x; for (x = 0; x y) { if (2.y > x) y + else x + x - y; y + x; for (x = 0; x
