The table below collects some statistics about the projects you gave back.

The first group of columns gives the size of each compiler in lines of Java code. These were collected trivially using the wc command, and are therefore not very representative of the actual code length. They give a rough idea, though. For each project, we report both the total line count, and the number of lines added to our initial version, which is 6580 lines long.

Then the speedups for the various benchmarks are reported. On two occasions, a compiler produced an incorrect program, and we decided to count this as a negative speedup of 5% (italicized in the table). We used a set of bigger inputs for these runs than the ones we had given you previously. These inputs are: fib.input, bignums.input, matrix.input, maze.input, sort.input. At the right end of the table, the average speedup is reported. This is the number we actually used to compute a part of the grade for this project.
