Estimated hours taken: 250 Add support for tabling. This change allows for model_det, model_semidet and model_non memoing, minimal model and loop detection tabling. compiler/base_type_layout.m: Update comments to reflect new runtime naming standard. compiler/det_analysis.m: Allow tabling to change the result of det analysis. This is necessary in the case of minimal model tabling which can turn a det procedure into a semidet one. compiler/det_report.m: compiler/hlds_data.m: Add code to report error messages for various non compatible tabling methods and determinism. compiler/hlds_out.m: compiler/modules.m: Remove reference to the old memo marker. compiler/hlds_pred.m: Create new type (eval_method) to define which of the available evaluation methods should be used each procedure. Add new field to the proc_info structure. Add several new predicates relating to the new eval_method type. compiler/inlining.m: compiler/intermod.m: Make sure only procedures with normal evaluation are inlined. compiler/make_hlds.m: Add code to process new tabling pragmas. compiler/mercury_compile.m: Call the tabling transformation code. compiler/modes.m: Make sure that all procedures with non normal evaluation have no unique/partially instantiated modes. Produce error messages if they do. Support for partially instantiated modes is currently missing as it represents a large amount of work for a case that is currently not used. compiler/module_qual.m: compile/prog_data.m: compiler/prog_io_pragma.m: Add three new pragma types: `memo' `loop_check' `minimal_model' and code to support them. compiler/simplify.m: Don't report infinite recursion warning if a procedure has minimal model evaluation. compiler/stratify.m: Change the stratification analyser so that it reports cases of definite non-stratification. Rather than reporting warnings for any code that is not definitely stratified. Remove reference to the old memo marker. compiler/switch_detection.m: Fix a small bug where goal were being placed in reverse order. Call list__reverse on the list of goals. compiler/table_gen.m: New module to do the actual tabling transformation. compiler/notes/compiler_design.html: Document addition of new tabling pass to the compiler. doc/reference_manual.texi: Fix mistake in example. library/mercury_builtin.m: Add many new predicates for support of tabling. library/std_util.m: library/store.m: Move the functions : ML_compare_type_info ML_collapse_equivalences ML_create_type_info to the runtime. runtime/mercury_deep_copy.c: runtime/mercury_type_info.h: runtime/mercury_type_info.c: Move the make_type_info function into the mercury_type_info module and make it public. runtime/Mmakefile: runtime/mercury_imp.h: Add references to new files added for tabling support. runtime/mercury_string.h: Change hash macro so it does not cause a name clash with any variable called "hash". runtime/mercury_type_info.c: runtime/mercury_type_info.h: Add three new functions taken from the library : MR_compare_type_info MR_collapse_equivalences MR_create_type_info. runtime/mercury_table_any.c: runtime/mercury_table_any.h: runtime/mercury_table_enum.c: runtime/mercury_table_enum.h: runtime/mercury_table_int_float_string.c: runtime/mercury_table_int_float_string.h: runtime/mercury_table_type_info.c: runtime/mercury_table_type_info.h: runtime/mercury_tabling.h: New modules for the support of tabling.
