What you'll learn

• Explain why compilers use intermediate representations instead of translating directly from AST to assembly
• Identify the main properties of a good IR: machine independence, ease of analysis, and ease of transformation
• Describe the typical phases of the optimization pipeline (high-level, machine-independent, machine-dependent)
• Define the structure of a three-address code instruction
• Translate simple arithmetic and assignment expressions into TAC
• Explain the roles of temporaries, labels, and control-flow instructions in TAC
