just the header comments at the top, though. Don't update to this rev if you don't have time for a complete rebuild, and exclude this rev if you want to see what's new across a range of commits. (this commit was certified error- and warning-free by the test-and-commit script.)
2012-06-09Cleanup and comments for the dag-ifier. Also some unit testing for it.Morgan Deters
2012-06-09Dagification of output expressions.Morgan Deters
By default, common subexpressions are dagified if they appear > 1 time and are not constants or variables. This can be changed with --default-expr-dag=N --- N is a threshold such that if the subexpression occurs > N times, it is dagified; a setting of 0 turns off dagification entirely. If you notice strange dumping behavior (taking too long to print anything, e.g.), revert to the old behavior with --default-expr-dag=0 and let me know of the problem.
