Learning outcomes:
Students will become acquainted with the concept of and motivation behind virtual machines using the CMa as an example.
Students will be able to translate C code to CMa code.
 
Students will be familiar with the most important program analyses (available expressions,
interval analysis, constant propagation, dead variables, etc.).
Students will be able to work out the (fixed-point) algorithms used in program analysis:
naive fixed-point iteration, round robin, worklist, recursive iteration.
Students will understand the mathematics behind the methods of analysis, in particular
the concept of complete lattices.
 
State-of-the-art analyzers will be used in the project
"Statische Analyse von sicherheitskritischem C-Code" to analyze code
used in industry. Students will gain insights into which analyses
are technically possible and how the development/programming style of
safety-critical software (e. g. from the aerospace or automotive
industry) differs from the development of
"normal software".
