Question

What is data-flow analysis in the code analysis stage of a decompiler?

a.

Where high-level control flow constructs are recovered from the unstructured control flow graph created by the front end

b.

Where complex and primitive data types are detected

c.

Where expressions are formed

d.

None of the above

Posted under Reverse Engineering

Answer: (c).Where expressions are formed Explanation:Data-flow analysis in the code analysis stage of a decompiler is where expressions are formed. This is why option c) is correct. Option a) is referring to control flow analysis, not data-flow analysis. Option b) is referring to type analysis, not data-flow analysis. Option d) is incorrect because data-flow analysis is a part of the code analysis stage.
