Contents:

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.

Exam FAQ:

  1. Attention: There will be only one exam at the end of the semester, and no repetition exam in the winter!
  2. You are allowed to bring all printed or handwritten material, you like
  3. In case you did not pass, you have the opportunity to take "Programming Languages" or "Program Optimization" next semester or alternatively repeat the exam next summer.
  4. We will provide two printouts of the lecture slides in case there is some information you forgot to add to your A4 sheet. We will also provide some copies of the RCMa specification document.
