Estimated hours taken: 12 Branches: main Split up three big compiler modules: llds_out.m, hlds_out.m (5000+ lines each) and deep_profiling.m (3000+ lines). Put the predicates in the resulting smaller modules into cohesive groups where possible. A few of the predicates in the original modules were unused; this diff deletes them. There are no algorithmic changes. compiler/llds_out_code_addr.m: New module containing the part of llds_out.m that outputs code addresses and labels. compiler/llds_out_data.m: New module containing the part of llds_out.m that outputs lvals, rvals and their components. compiler/llds_out_global.m: New module containing the part of llds_out.m that generates global static C data structures. compiler/llds_out_instr.m: New module containing the part of llds_out.m that outputs instructions compiler/llds_out_file.m: New module containing the top level part of llds_out.m, which coordinates the generation of a whole C source file. compiler/llds_out_util.m: New module containing the utility parts of llds_out.m. compiler/llds_out.m: Replace everything in this file with just the includes of the submodules that now have all its previous contents. compiler/hlds_llds.m: Move a predicate here from llds_out.m, since it is a utility predicate operating on a type defined here. compiler/rtti_out.m: Move a predicate here from llds_out.m, since it is a predicate generating output from a rtti type. compiler/hlds_out_mode.m: The part of hlds_out.m that deals with writing out insts and modes. compiler/hlds_out_goal.m: The part of hlds_out.m that deals with writing out goals. compiler/hlds_out_pred.m: The part of hlds_out.m that deals with writing out predicates and procedures. compiler/hlds_out_module.m: The part of hlds_out.m that deals with writing out module-wide tables. compiler/hlds_out_util.m: Parts of hlds_out.m that don't fit in anywhere else. compiler/hlds_out.m: Replace everything in this file with just the includes of the submodules that now have all its previous contents. compiler/simplify.m: compiler/hlds_goal.m: Move some insts from simplify.m to hlds_goal.m to allow hlds_out_goal.m to use them also. compiler/coverage_profiling.m: The part of deep_profiling.m that deals with coverage profiling. compiler/deep_profiling.m: Remove the code moved to coverage_profiling.m, and export the utility predicates needed by coverage_profiling.m. Remove the things moved to prog_data.m and hlds_goal.m. Put the predicates into a more logical order. compiler/hlds_goal.m: Move some predicates here from deep_profiling.m, since they belong here. compiler/prog_data.m: Move a type from deep_profiling.m here, since it belongs here. compiler/add_pragma.m: Add a predicate from llds_out.m that is used only here. compiler/*.m: Conform to the changes above.
