Objectives

Study and implementation of principles of construction of compiler and interpreters for imperative programming languages.

Learning outcomes and competences

At the end of this course students should be able to:
1) Understand the decomposition of a compiler in phases: lexical analysis, syntactical analysis, semantic analysis, intermediate code generation and machine code generation
2) Understand the concept of concrete and abstract syntax and intermediate language representations
3) Implement a compiler for a small imperative programming language following the phases of point 1)

Working method

Presencial

Pre-requirements (prior knowledge) and co-requirements (common knowledge)

Basic knowlege of imperative and functional programming.
Basic knowlege of assembly language (e.g. MIPS).
Models of computation (regular expressions, finite automata and context free grammars).

Program

Introduction to programming language execution principles. Compilers vs interpreters. Lexical analysis. Scanner generators. Syntactic analysis (LL,LR, LALR parsers). Parser generators. Syntax oriented compilation. Attribute grammars. Semantic analysis: symbol table, type checking. Activation records. Three address code translation. Code generation: flow analysis, register allocation.

Eligibility for exams

To be eligible for exam the student should be present at the two assement moments for the practical project.

Calculation formula of final grade

Final mark = 15*P1 + 15%*P2 + 70%*E

where

P1: Mark for the 1st project milestone
P2: Mark for the 2nd project mileston
E : Mark obtained in exam

To obtain aproval the student must achive a minimum of 40% mark on the exam.

Special assessment (TE, DA, ...)

The assement parameters are the same as for ordinary students.
Eligibility for exam of worker students requires only the presentation of the two assement phases of the practical project.

Classification improvement

Students may attend the exam and improve their grade in that assement parameter, but maintain the grade of the project component and practical exercises of their first aproval.
