Students learn basic compiling methods of programming languages. They are introduced to intermediate representations used in current compilers GNU and LLVM. They learn to create a specification of a translation of a text that conforms a given syntax, to a target code and also to create a compiler based on the specification. The compiler can translate not only a programming language but any text in a language generated by a given LL input grammar.


The theory of automata and grammars, basic knowledge of programming (C and C++).

Theory of automata and grammars in the scope of BIE-AAG.21, basic knowledge of programming (C and C++).

A prerequisite for enrollment in BIE-PJP.21 is that the student has earned at least credit for BI-AAG.21 in a previous semester.

Syllabus of lectures:

1. Structure of a compiler, lexical analysis.

2. Deterministic top-down parsing: LL parsing.

3. [2] Implementing LL parsing, properties of LL grammars.

5. Transformations to LL(1) grammars, error recovery during LL parsing.

6. Formalisms for syntax-directed translation and semantics: translation and attributed grammar.

7. One-pass attributed translation directed by LL parsing, L-attributed grammars, examples of simple translations.

8. Data structures of a compiler, intermediate representations.

9. Abstract syntax tree, three address code - intermediate representations of GNU compiler.

10. Intermediate representations of the LLVM compiler.

11. An example of a simple compiler.

12. Local code optimization.

13. Other variants of LL parsing.

Syllabus of tutorials:

1. Lexer design and implementation.

2. Parser implementation using recursive descent.

3. Attribute translation grammars.

4. Compiling to a language of a stack machine.

5. Compiling to a syntax tree.

6. [2] Project consultations.

Study Objective:

After completing the course, students will be able to formally specify a translation of a text that has a certain syntax into the target form and write a compiler based on such specification. The notion of compiler in this context is not limited to compilers of programming languages but extends to all other programs for parsing and processing text in a language defined by a LL(1) grammar.
