Jules Villard 9690dba871 [pulse] a slow example for pudge ... Summary: Add a test to the repo to try and detect perf regressions in pulse. Currently analyzed in ~0.1s. With `--pudge`, takes ~10s. Sledge does eager normalization and canonicalization when incorporating new facts into formula contexts and the algorithm is polynomial in the number of equalities. This example generates one equality per location in the array => boom. This bypasses the recency model of arrays because the formula needs to be constructed before it can be simplified to get rid of dead variables. The new arithmetic is not as complete as sledge's algorithm but linear in time. We could use it to simplify the formula *before* passing it to sledge. In fact, that was the original motivation.
