Goals
Give Ph.D. students or practitioners knowledge about advanced compiler technology, including program analysis, intermediate representations, compiler optimizations, code generation, compiler frameworks, run-time systems, and compilation techniques for parallel and embedded systems.

Prerequisites
Basic course in compiler construction, corresponding to the undergraduate courses Compilers and Interpreters, or Compiler Construction.
Basic course in data structures and algorithms.
Basic knowledge in processor architecture.
For the labs: Programming in C++/Linux.

Organization
Lectures, lessons, programming labs, a written assignment, and student paper presentations.

Lectures are given in 2 intensive weeks, usually 09:15-12 and 13:15-17 every day.

Lessons are problem solving sessions, discussing exercises to complement the lectures. The lessons are moderated by the course assistant, Erik Hansson. The exercise sets are available here.

Lab series (3hp) using the LLVM compiler system.
Lab introduction slides
Lab instructions, part 1.
Lab instructions, part 2.

The lab assistant, Erik Hansson, will supervise labs and correct lab reports.

The presentation part of the course consists of student presentations of about 30 minutes each (25 minutes presentation plus 5 minutes questions) on a recent paper in compiler technology, with a written summary of 1-2 pages to be delivered within one week after the presentation. It also includes opposition of one other presentation.
See this link for detailed instructions and the list of assigned student papers.
For admission to the presentation it is required that at least 50% of the lectures and lessons have been attended.

Written exam: prel. friday 10/10, 13-17. Room: von Neumann, IDA, Linköping.
For participants from other sites: Contact the examiner in time if you intend to write the exam at your home university, and give the contact data of a teacher who will supervise your exam there.
No aids are allowed, except for a dictionary from English to your native language. Last admission time is 14:30.
For admission to the exam it is required that at least 50% of the lectures and lessons have been attended.

Old exams:
Part 1 (PDF), Part 2 (PDF), Solution proposal part 2 (PDF)

Literature
You should be able to follow the course mainly based on the slide material only. The following books and papers are recommended as additional reading wherever necessary:

Books:

No textbook covers the entire course contents completely. But parts of either of the following books and articles can be useful as accompanying text for a major part of the course (these are also available in the local library):

  • Alfred Aho, Monica Lam, Ravi Sethi, Jeffrey Ullman: Compilers: Principles, Techniques, and Tools. Second edition, Addison-Wesley, 2006.

  • Y.N. Srikant, P. Shankar (ed.): The compiler design handbook: optimizations and machine code generation, CRC Press, 2003.
    (Available in TekNat-library, also the first edition..
    More complete and more up to date than Muchnick's book, but a collection of independent chapters rather than a monograph, and expensive.)
    In particular, chapters 1 (WCET/WCEE analysis, using e.g. abstract interpretation techniques), 5 (Optimizations for memory hierarchy), 7 (Energy-aware compiler optimizations), 11 (SSA form), 16 (ADLs for retargetable compiling), 17 (Instruction selection), 18 (DSP VLIW compiler), 19 (Instruction scheduling), 20 (Software pipelining). The first edition contains a chapter on dataflow analysis.

  • Michael Scott: Programming Language Pragmatics. Morgan Kaufmann, 2000. (Excellent summary of concepts in programming languages and their implementation in compilers. Chapter 13 gives a summary of code optimization.)

LAB2: Compiler framework lab with written report 3hp (course assistant: Erik Hansson) Deadline: TBA

PRE1: Presentation, opposition and written summary 1.5hp (Christoph) Deadline (summary): TBA
For admission to the presentation it is required that at least 50% of the lectures and lessons have been attended.

Credit
Up to 9hp for the entire course, provided that the written exam is passed.
Admission to the exam and presentation requires physical presence in at least 50% of all lectures and lessons.
