Estimated hours taken: 18 Branches: main Move the univ, maybe, pair and unit types from std_util into their own modules. std_util still contains the general purpose higher-order programming constructs. library/std_util.m: Move univ, maybe, pair and unit (plus any other related types and procedures) into their own modules. library/maybe.m: New module. This contains the maybe and maybe_error types and the associated procedures. library/pair.m: New module. This contains the pair type and associated procedures. library/unit.m: New module. This contains the types unit/0 and unit/1. library/univ.m: New module. This contains the univ type and associated procedures. library/library.m: Add the new modules. library/private_builtin.m: Update the declaration of the type_ctor_info struct for univ. runtime/mercury.h: Update the declaration for the type_ctor_info struct for univ. runtime/mercury_mcpp.h: runtime/mercury_hlc_types.h: Update the definition of MR_Univ. runtime/mercury_init.h: Fix a comment: ML_type_name is now exported from type_desc.m. compiler/mlds_to_il.m: Update the the name of the module that defines univs (which are handled specially by the il code generator.) library/*.m: compiler/*.m: browser/*.m: mdbcomp/*.m: profiler/*.m: deep_profiler/*.m: Conform to the above changes. Import the new modules where they are needed; don't import std_util where it isn't needed. Fix formatting in lots of modules. Delete duplicate module imports. tests/*: Update the test suite to confrom to the above changes.
For documentation on the deep profiler, see the following:
- The "Deep Profiler" section of the Mercury web page
<http://www.cs.mu.oz.au/mercury/information/deep_demo.html>
gives an overview of what deep profiling is.
- The deep profiling paper on our web site, "Deep profiling:
engineering a profiler for a declarative programming language"
<http://www.cs.mu.oz.au/mercury/information/papers.html#mu_01_24>
explains in detail what deep profiling is, why it is needed,
and how it is implemented in the Mercury compiler.
- The "Using mdprof" section of the "Profiling" chapter of the
Mercury user's guide explains how to use it.
- The file deep_profiler/notes/deep_profiling.html gives an overview of
the specifics details of our implementation of deep profiling.
