 The Algebraic With-Loop Folding (AWLF) project extends the capability of the With-Loop Folding optimization One problem we have observed in AWLF, specifically in the apex/​logd3/​logd.sac benchmark, is that WLSIMP eliminates a degenerate WL, replacing it by a sel() into a producerWL that may be otherwise unused. This results in degraded performance,​ because the producerWL generates a large intermediate result, but we only use one element of that result. The Algebraic With-Loop Folding (AWLF) project extends the capability of the With-Loop Folding optimization One problem we have observed in AWLF, specifically in the apex/​logd3/​logd.sac benchmark, is that WLSIMP eliminates a degenerate WL, replacing it by a sel() into a producerWL that may be otherwise unused.
