Estimated hours taken: 12 Branches: main compiler/*.m: Convert predicates that used to have one clause for each kind of HLDS goal into explicit disjunctions, since this gives the debugger a meaningful name for each argument. In some cases, this exposed arguments that were used by *no* clause. In other cases, it allowed factoring out common code, as well as code that *should* have been common but wasn't. Put the disjuncts in a meaningful order. In too many cases, they were almost random. Merge the resulting predicates into their parents, in places where the Prolog indexing one could get from separate clauses was the only reason for separating those predicates from their parents in the first place. Similarly, merge child predicates handling generic call kinds and such back into the main predicate where this improves clarity. In some cases, this allows putting the extraction of hlds_goal_expr from a hlds_goal into one place, instead of repeating it in lots of places. Give some predicates more descriptive names. In some cases, rationalize argument order. In some cases, rationalize the order of predicates in the module. Replace some uses of booleans with purpose-specific types. Give some fields names, and put type-identifying prefixes on the names of other fields, to make tag files work better. In some cases, reorder fields to them put into related groups. Use more standard and/or more descriptive variable names Use a standard syntax for if-then-else in each module. Follow our style convention for comments.
