Study notes

Intermediate, Built from scratch. Step 7 of 10 in How a computer works

Helpful first

• Comfort reading code
• Basic computer architecture

What it builds

• Separate source-language structure from execution.
• Identify the parser and intermediate representation inside a compiler.
• Connect compiler output to a virtual machine.

Useful moments

• 0:21Virtual machines and the example compiler
• 1:00Parser and intermediate representation

Check yourself: Why is translating source text directly into machine behaviour usually split into stages?
