| # Source Code Representation | |
| This part describes the process of taking raw source code from the user and | |
| transforming it into various forms that the compiler can work with easily. | |
| These are called _intermediate representations (IRs)_. | |
| This process starts with compiler understanding what the user has asked for: | |
| parsing the command line arguments given and determining what it is to compile. | |
| After that, the compiler transforms the user input into a series of IRs that | |
| look progressively less like what the user wrote. |
