What is the advantage of using an abstract syntax tree (AST) in intermediate code generation?

Step 1: Understand what an abstract syntax tree (AST) is. It is a tree-like structure that represents the syntax of a program in a hierarchical way.
Step 2: Recognize that the AST shows the relationships between different parts of the program, like functions, variables, and operations.
Step 3: Compare the AST to a linear representation (like a list of instructions). A linear representation is flat and does not show how parts of the program relate to each other.
Step 4: Realize that because the AST is hierarchical, it is easier to see patterns and relationships, which helps in optimizing the code.
Step 5: Conclude that using an AST in intermediate code generation allows for more effective optimizations, leading to better performance of the final program.
