% This module contains information about various modules of the Mercury
% standard library that serve to implement various kinds of builtin operations.
% The compiler can generate references to types, predicates or functions
% in these modules, and the debugger and the profilers need access to
% many of these as well.

% XXX We do not document whether the functions in this section are
% intended to return, when we start add a "std" wrapper around the
% names of modules in the Mercury standard library,
%
% - the name without the wrapper, or
% - the name with the wrapper.
%
% At the moment, the two are identical, so the issue is moot.
% However, different parts of the rest of the system seem to make
% conflicting assumptions about the answer, and these will have to be
% sorted out if/when we add that wrapper.
% Returns all the modules which are automatically imported.
%
:- func all_builtin_modules = list(sym_name).
% Returns the name of the module containing public builtins;
% originally this was "mercury_builtin", but it later became
% just "builtin", and it may eventually be renamed "std.builtin".
% This module is automatically imported, as if via `import_module'.
%
:- func mercury_public_builtin_module = sym_name.
% Returns the name of the module containing private builtins;
% traditionally this was "mercury_builtin", but it later became
% "private_builtin", and it may eventually be renamed
% "std.private_builtin". This module is automatically imported,
% as if via `use_module'.
%
:- func mercury_private_builtin_module = sym_name.
% Returns the name of the module containing builtins for region-based
% memory management. This module is automatically imported iff
% RBMM is enabled.
%
:- func mercury_region_builtin_module = sym_name.
% Returns the name of the module containing builtins for software
% transactional memory.
% This module is automatically imported iff STM is used in a module.
%
:- func mercury_stm_builtin_module = sym_name.
% Returns the name of the module implementing exceptions.
% This module is automatically imported iff STM is used in a module.
%
:- func mercury_exception_module = sym_name.
% Returns the name of the module implementing univs.
% This module is automatically imported iff STM is used in a module.
%
:- func mercury_univ_module = sym_name.
% Returns the name of the module containing builtins for tabling;
% originally these were in "private_builtin", but were then moved into
% a separate module. This module is automatically imported iff any
% predicate is tabled.
%
:- func mercury_table_builtin_module = sym_name.
% Returns the name of the module that handles tabling statistics.
% This is separate from table_builtin, since its contents need to be
% visible to users, while the contents of table_builtin are private.
% This module is automatically imported iff any tabled predicate
% gather statistics.
%
:- func mercury_table_statistics_module = sym_name.
% Returns the name of the module containing the builtins for deep
% profiling. This module is automatically imported iff deep profiling
% is enabled.
%
:- func mercury_profiling_builtin_module = sym_name.
% Returns the name of the module containing the builtins for term size
% profiling. This module is automatically imported iff term size profiling
% is enabled.
%
:- func mercury_term_size_prof_builtin_module = sym_name.
% Returns the name of the module containing the builtins for parallelism.
% This module is automatically imported iff building in a .par grade.
%
:- func mercury_par_builtin_module = sym_name.
% Returns the name of the module containing the RTTI implementation for
% certain backends.
%
:- func mercury_rtti_implementation_builtin_module = sym_name.
% Returns the name of the module containing the builtins for the
% source-to-source debugger.
%
:- func mercury_ssdb_builtin_module = sym_name.
% Returns the name of the list module.
%

% Succeeds iff the specified module will never be traced.
%
:- pred non_traced_mercury_builtin_module(sym_name::in) is semidet.
%---------------------------------------------------------------------------%
% Returns the sym_name of the module with the given name in the
% Mercury standard library. In the future, this may add a wrapper
% around the original module name, though for now, this function
% is a no-op.
%
% NOTE: If you want to change the status quo, see the XXX above
% about conflicting assumptions.
%
:- func maybe_add_stdlib_wrapper(module_name) = module_name.
% Remove any wrapper added by maybe_add_stdlib_wrapper, without checking
% whether the module name inside is actually the name of a module
% in the Mercury standard library or not. If you want that check,
% call is_std_lib_module_name instead. This predicate is intended
% for uses which follow a call to the predicate with tests for
% individual, specific standard library modules. In such cases,
% a generic test for "does this module name occur in the standard library"
% would be useless work.
%
% At the moment, maybe_add_stdlib_wrapper does not add a wrapper,
% so cannot fail to find it. This is why this predicate is deterministic.
% When we change maybe_add_stdlib_wrapper to add a wrapper, this predicate
% will change to be semidet.
