The Result of the Compiler Construction Competition

The compilers were tested on a large collection of programs.

Correctness as well as speed of Knapsack.hun for the different groups can be seen below. Note that marks in the tables do not necessarily indicate an error situation. We have also used these tests to see which run-time errors the groups have decided to catch, and to get a feel for decisions regarding evaluation orders etc.

Thus, some of the markings indicate indisputable errors whereas others more have the character of decisions reflecting matters of opinion. So, some markings have not been counted as errors, and among the ones which have been counted as errors, some are more serious than others.

Also note that features other than correctness and speed have also been taking into account.

The winners

The lecturer and teaching assistant of the course have together evaluated the compilers and we have agreed to announce the following group as winner of the competition:

Group 4
Alexei Mihalchuk
Kenneth A. Knudsen
Lars Andersen
The decision was based on a perfect test score with regards to correctness and very fast code on the announced speed test.

Honorary Award

This does not happen every year, but we have this year decided to grant an honorary award. The compiler of this group did very well on correctness and contained advanced garbage collection. In addition, the work was carried out by one person.

The recipient of the honorary award is the following group:

Group 7
Thies Pierdola
