Compiler Construction

Speaker Dr. Michael Petter
Location BBB
Date Thursday, 14:00 - 16:00
Module IN2227

News

  1. Due to COVID-19, we plan to give the lecture in form of Flipped Classroom. This means, that you get TTT recordings of the lecture in advance, and pepare for a virtual classroom in form of a teleconference where you can ask questions, work on examples, discuss deeper topics etc.
  2. As for the tutorial, this will also be in form of a teleconference

A Compiler is an essential part of the system software stack. Its job consists in translating programs from a high-level programming language like C or Java into a sequence of machine instructions of an actual processor. Compilers are comparatively complex programs. Their construction involves ideas and approaches from many different areas of computer science. The first two phases, i.e. lexical and syntactical analysis of the input program, are a major application for formal methods. Later on, e.g. during code generation, we treat methods for register allocation via approximative graph colouring.

The lecture is divided into the following topics:

  1. Outline of compiler construction
  2. Lexikal analysis:
    From regular expressions to NFAs
    Scannerdesign with NFAs
  3. Syntactical analysis
    Contextfree languages & pushdown automata
    Item-Pushdownautomata & Recursive Descent Parsing
    Shift-Reduce Parsing & LR(1) Parser
  4. Semantical analysis
    Attributevaluation
    Typechecking
  5. Codegeneration
    Registerallocation
    Code generation schemes
  6. Optimizations

Finally we may find time for less standard techniques for compilers, as e.g. the type inference of programs.

Tutorial

The tutorial is given by Michael Schwarz, Mondays from 14:15-15:45, starting on May 4th. Join the tutorial in moodle!
