Compiler of a pseudo-asssembly langage for a school project

Corewar ASM compiler

My part of one of the final project of the first part of the 42 cursus It's a compiler of a pseudo-asm language.

The bytecode generated are used in a other part of the subject!

How to create a champ (not a good one, just one that don't throw an error)

• You should have a .name and .comment section with something in !
• You should use choose an instruction and some args, that work with (be carefull with the type of the argument!)
• The operation are described here : https://docs.google.com/spreadsheets/d/1pFwSCne-mh-u5ZLsjZS8VI9QvecYk-gWTyNaPstjpLE/edit#gid=0

What is my program doing ?

• I'm parsing the .s file that you're giving to me !
  • I'm getting the .name and .comment and keep it safe in my cool structure 😎
  • If there's a label ( label: for instance ), I'm adding it to a list of labels, keeping his address in this list
  • And I'm parsing all the instructions with his args, adding all instructions in another linked list!
• After, I'm looking for calls to a label in my instruction ( jmp %:label for instance), and change the content of the instruction by the address of the label!
• And I'm good, I just need to write to my .cor file!
  • I'm writing the name and comment of course!
  • I need to calculate some parameter encode number (it's just some binary mask)
  • Then I'm writing it directly in a file, for instance if I have a live %42 I writing to my file : 01 00 00 00 2a ,01 being the opcode.
