Question

What is the difference between linear sweep and recursive traversal in disassembly?

a.

Linear sweep disassembles instructions sequentially, while recursive traversal follows the control flow instructions in the program.

b.

Linear sweep disassembles instructions recursively, while recursive traversal follows the control flow instructions in the program.

c.

Linear sweep disassembles instructions based on their length, while recursive traversal disassembles instructions randomly.

d.

Linear sweep disassembles instructions based on their location, while recursive traversal disassembles instructions based on their length.

Answer: (a).Linear sweep disassembles instructions sequentially, while recursive traversal follows the control flow instructions in the program. Explanation:Linear sweep is the trivial approach that simply disassembles instruction sequentially in the entire module. Recursive traversal is the more intelligent approach whereby instructions are analyzed by traversing instructions while following the control flow instructions in the program.
