Descriptors: Representation of formal languages, lexical analysis, syntactic analysis, semantic analysis, code generation, error recovery, code optimization UNIT I: Introduction History of compilers and languages Basics Languages and grammars Formal definitions of Grammar, Regular Expressions and Automata Phases and structure of a compiler Tombstone diagrams TOPIC II: Lexical Analysis Design of a Lexical Analyzer Finite Automata Regular Languages ¿¿recognizers Construction of a Finite Automaton. Examples Automatic Lexical Analyzer Generator: LEX Handling Lexical Errors THEME III: Parsing Introduction to Syntactic Analysis Classification of methods of syntactic analysis Descending Scan, Syntactic LL LL obtaining table (1). Examples Ascending Scan, Syntactic LR Treatment of Ambiguous Grammars. Examples Automatic Parser Generator: YACC UNIT IV: Treatment of Syntactic Errors Errors. Detection and Recovery Strategies. Examples Recovery with different analyzers Descent parser LL Up operator precedence parser Ascending LR Parser UNIT V: Semantic Analysis Attribute Grammars, Examples, Registration Specifying a translator: Translation Directed by Syntax and Translation Schemes Evaluation of grammars Construction of Abstract Syntax Trees UNIT VI: Verification of Types Introduction Type expressions Type systems. Checking static and dynamic Sample construction and verification of simple types Equivalence of type expressions Overloading and Object Orientation UNIT VII: Intermediate Code Generation Types of Intermediate Languages Codes three directions. Alternatives Intermediate code generation: statements, arithmetic expressions, arrays Control Flow Statements UNIT VIII: Machine Code Generation Machine and target machine code Options machine code Instructions and addressing and cost Simple code generation from intermediate language Basic blocks and flow graphs Register allocation Translation of other instructions UNIT IX: Table of Symbols and Execution Environment Memory allocation Static and dynamic allocation Stack and heap management. Examples Function calls Activation records Passing parameters Operations and organization of the symbol table UNIT X: Code Optimization Code optimization concept Local optimization of basic blocks Function preserving transformations Elimination of dead code Loops optimizatio Global analysis of the data stream UNIT XI: Specific Aspects Other language processor interpreter Preprocesadotes and macroprocesadores Language desig Data structures and contro Aspects of compilation for specific types of language Examples of compilers
Learning activities and methodology
Theoretical lectures: 1.5 ECTS. To achieve the specific cognitive competences of the course. Practical lectures: 1,5 ECTS. To develop the specific instrumental competences and most of the general competences, such as analysis, abstraction, problem solving and capacity to apply theoretical concepts. Besides, to develop the specific attitudinal competences. They consist in proposing during the practical lectures a compiler/interpreter project to be developed in teamwork. -Guided academic activities (present teacher): 1 ECTS. The student proposes a project according to the teachers guidance to go deeply into some aspect of the course, followed by public presentation. -Guided academic activities (absent teacher): 1.5 ECTS. Exercises and complementary readings proposed by teacher. Exercises and examination: 0,5 ECTS. To complete the development of specific cognitive and procedimental capacities.
