There may be some advantage to trying to be smarter about the initial placement, rather than putting everything at the end. -2. The handling of 2-byte padding for Thumb is overly conservative. There -would be a small gain to keeping accurate track of the padding (which would -require aligning functions containing constant pools to 4-byte boundaries). - -3. There might be some compile-time efficiency to be had by representing +2. There might be some compile-time efficiency to be had by representing consecutive islands as a single block rather than multiple blocks. -4. Use a priority queue to sort constant pool users in inverse order of +3. Use a priority queue to sort constant pool users in inverse order of position so we always process the one closed to the end of functions first. This may simply CreateNewWater.
