Question

What is the purpose of the special notation used in data-flow analysis?

a.

To define a register, which means that it is loaded with a new value.

b.

To define a register, which means that its value is read.

c.

To simplify the process of identifying various points in the code where a register is defined in parallel in two different branches in the control flow graph.

d.

All of the above.

Posted under Reverse Engineering

Answer: (d).All of the above. Explanation:The special notation used in data-flow analysis must conveniently represent the concept of defining a register, which means that it is loaded with a new value and using a register, which simply means its value is read. The notation should also simplify the process of identifying various points in the code where a register is defined in parallel in two different branches in the control flow graph.
