Estimated hours taken: 4 Branches: main Add new fields to the goal_info structure for region based memory management. The fields are currently unused, but (a) Quan will add the code to fill them in, and then (b) I will modify the code generator to use the filled in fields. compiler/hlds_goal.m: Make the change described above. Group all the procedures that access goal_info components together. Some of the getters were predicates while some were functions, so this diff changes them all to be functions. (The setters remain predicates.) compiler/*.m: Trivial changes to conform to the change in hlds_goal.m. In simplify.m, break up a huge (800+ line) predicate into smaller pieces.
