  1. LL Compiler Igor Dultsev DanilTumaykin Winter School 2012 @ NSU-Intel Lab

  2. Project Specification How we saw our project at the beginning: • Source Language: LL(Lisp Dialect – Little Lisp) • Target: C, maybe our VM Code • Project Language: C# • VCS: git/github.com • License: CC • Deadline: 2012/02/04 • Key features: standard types, list, string, λ-functions • Standard library • Interface: • Console, GUI • Unit Tests

  3. Architecture & Design Four phases – four classes: • Lexic analyzer – Lexer • Syntax analyzer - Parser • Semantic analyzer • Code generator

  4. Lexer Performs lexical analysis of LL language source code. Input: String containing LL source. Output: Collection of IToken’s.

  5. Lexer use sample (defunsqr (x) (* x x))

  6. Parser Parses a collection of IToken’s into a collection of IParsedValue’s. Input: Collection of IToken’s.. Output: Collection of IParsedValue.

  7. Parser Use Sample (defun f (x y) (+ (* x y) 7))

  8. Semantic analyzer Adds semantic information to the parse tree and builds the symbol table & computes types information. Input: Collection of IParsedValue. Output: List of Function’s.

  9. Semantic analyzer use sample

  10. Type System Any Int Char String List Nothing

  11. Code generator Generates code from a Function’s. CG also generates code snippets for standart functions. Input: List of Function’s. Output: List of GeneratedCFunction’s, string or file.

  12. Code generation sample

  13. GUI

  14. Features we didn’t implemented (yet) • Our VM Bytecode Generator • λ-functions • Standard Library • Good IDE :o

  15. Why did we do it at all? • Projects reasons-to exists • Future • Intel-NSU Laboratory compiler project

  16. Thank you! Q&A Section begins here
