Specifically, make it warn about interface imports that are not used
in the initial HLDS, even if they *are* used after the expansion of
type-, inst- and mode-equivalences.
compiler/hlds_module.m:
Add a slot to the HLDS to store the set of modules that are
imported in the interface but are unused there when the HLDS
is first constructed.
compiler/module_qual.qualify_items.m:
Compute this set, and return it to mercury_compile_make_hlds.m.
Make the code module qualifying aug_compilation_units warn about
unused interface imports only if unused_imports.m won't do the same later.
compiler/mercury_compile_make_hlds.m:
Pass the set to make_hlds_passes.m.
compiler/make_hlds_passes.m:
Store the set in the initial HLDS.
compiler/prog_data_used_modules.m:
Replace set_ordlists with set_tree234s.
compiler/unused_imports.m:
Consider an interface-imported module unused in the interface
if module_qual.qualify_items.m considered it unused, even if
changes made by equiv_type.m has added uses of it later.
compiler/handle_options.m:
Stop making --warn-unused-imports imply --no-warn-unused-interface-imports,
since new logic in module_qual.qualify_items.m makes this unnecessary.
compiler/make_module_file_names.m:
compiler/type_inst_mode_map.m:
compiler/write_deps_file.m:
Move imports from the interface section to the implementation section,
in response to the new, more thorough warnings.
Mercury
Mercury is a logic/functional programming language which combines the clarity and the expressiveness of declarative programming with advanced static analysis and error detection features.
More information is available on the website's about pages, in other README files in the source code repository, and in the documentation.
Small sample programs written in Mercury can be found in the samples and extras directories of the source code repository.
README files
The Mercury compiler has two different backends and works on different operating systems. Specific information is contained in individual README files:
-
Bootstrapping discusses how to get Mercury installed.
This is important, as the Mercury compiler is written in Mercury.
-
C Low-level backend
This backend works well with GCC but also works with:
-
High-level backend targets
-
Supported operating systems
-
Other platform information
Other information
See the current release notes for the latest stable release. The news file lists any recent changes. The history file is relevant if you want to find out more about the past development of Mercury. The limitations file lists some ways in which the Mercury implementation does not yet meet its goals.
Information for developers
If you are considering contributing to the Mercury project, the website contains some documents that may be helpful. These include a document about contributions in general and specific information about contributing such as coding styles.
