Commit 92f60e5c7 inadvertently changed the conjunction operator recognised by
this program from "," to ", ". Fix that.
samples/interpreter.m:
tests/debugger/interpreter.m:
As above.
compiler/unused_args.m:
Make the new version of a test succeeds, where the old version
*looked like* it failed, but did not.
compiler/lambda.m:
Fix misleading module comment.
compiler/build_eqv_maps.m:
compiler/equiv_type.m:
As above.
compiler/parse_tree.m:
compiler/notes/compiler_design.html:
Include and document the new module.
compiler/decide_type_repn.m:
compiler/equiv_type_hlds.m:
compiler/make_hlds_passes.m:
compiler/mercury_compile_make_hlds.m:
compiler/qual_info.m:
Conform to the changes above.
compiler/parse_type_defn.m:
As above.
tests/invalid/field_syntax_error.{m,err_exp}:
tests/invalid/types.{m,err_exp}:
Add an instance of each bug the diagnostics are for,
and test for the updated diagnostic text.
compiler/parse_module.m:
When complaining about missing ":- interface"/":- implementation" markers,
reword the diagnostic to clarify that these should come after
the initial ":- module" declaration.

Expect the updated wording.
compiler/unused_args.m:
The old code that we use to decide whether we want to warn
about unused args in a predicate was built up piecemeal
over a long time, mostly before the creation pred_origins.
It never had a cohesive design.
Add a new version of the test that has a cohesive design,
consisting of just a test of the pred_status, and a case analysis
of the various possible values of the pred's origin.
Add code to automatically compare the result of the old and new tests,
and abort if they do not match. After a few days of tests on code
other than the Mercury system that don't trigger any of the new exceptions,
we can throw away the old code.
When set, this option tells the compiler to generate warnings
about locally-defined types that are neither used in the module
nor exported to any other module.
compiler/options.m:
Add the new option.
compiler/unused_types.m:
New module to implement the new option.
compiler/mercury_compile_front_end.m:
Invoke the new module, unless the presence of previous errors
would make its warnings just a distraction.
compiler/check_hlds.m:
Include the new module.
compiler/notes/compiler_design.html:
Document the new module.
compiler/typecheck_error_wrong_type.m:
Simplify some code.
browser/declarative_tree.m:
compiler/accumulator.m:
compiler/du_type_layout.m:
compiler/intermod.m:
compiler/mode_errors.m:
compiler/parse_inst_mode_defn.m:
compiler/polyhedron.m:
compiler/split_parse_tree_src.m:
compiler/tag_switch_util.m:
compiler/typecheck_error_unify.m:
compiler/unneeded_code.m:
deep_profiler/mdprof_test.m:
library/getopt.m:
library/getopt_io.m:
Delete unused types reported by the new option.
library/rtti_implementation.m:
Comment out unused type reported by the new option. This type was exported
to both Java and C#, but this diff comments it out because neither language
the Java or the C# runtime system seems to use the exported versions
either. (Bootcheck in both java and csharp grades worked, with the
same number of test case failures as before.) We do not delete it,
because it may be useful in the future.
tests/warnings/help_text.err_exp:
Expect the documentation of the new option.
tests/invalid_nodepend/Mmakefile:
Specify --warn-unused-types for two test cases to test that the compiler
does NOT generate warnings about unused types in the presence of previous
errors.
tests/warnings/abstract_type_decl.err_exp:
tests/warnings/bug412.err_exp:
tests/warnings/warn_dead_procs.err_exp:
Expect the new warnings for unused types.
tests/warnings/Mmakefile:
Specify --warn-unused-types for the three test cases listed above.
compiler/mercury_compile_middle_passes.m:
Pass the main predicate of unused_args.m two flags that together
specify what it should do, besides generating warnings. This makes
the code easier to understand, since each ignored argument representing
a set of unused_args pragmas is now preceded by a flag argument
that says "do not generate those pragmas".
compiler/unused_args.m:
Delete the code for deciding whether (a) we want to generate unused_args
pragmas or (b) record unused_args information in the analysis registry.
This is because the code doing that was duplicating the code fragments
in mercury_compile_front_end.m and mercury_compile_augment.m that decided
which predicate to call in mercury_compile_middle_passes.m:
either middle_pass_for_opt_file, or output_analysis_file.
This duplication not only violates the "Don't repeat yourself" principle",
but also led to hard-to-understand code in unused_args.m.
This addresses an XXX added by Zoltan in commit eb623b17a,
which misunderstands what the intended semantics of the duration/0
type are.
library/calender.m:
As above.
compiler/unused_args.m:
Put both the primitive operations on the module's main analysis
data structure, and the code required for the analysis typeclass
instances, into separate blocks near the end of the module,
just before the debugging routines.
Replace more uses of bools with the maybe_changed type.
Do not allocate new hlds_goal structures that are identical to
already existing hlds_goal structure.
Carve two new small predicates out of an existing too-big one.
Make some other simplifications, and improve some other type,
predicate and variable names.
compiler/maybe_util.m:
Add two utility functions for use by unused_args.m.
compiler/mmc_analysis.m:
As above.
compiler/exception_analysis.m:
compiler/structure_reuse.analysis.m:
compiler/structure_sharing.analysis.m:
compiler/tabling_analysis.m:
compiler/trailing_analysis.m:
compiler/unused_args.m:
Conform to the changes above.
Give some types, predicates and variables more descriptive and more
consistent names.
Document some predicates rather better. Add XXXs indicating where
further documentation would help :-(
Redirect some references to map.set to map.det_{insert,update}.
samples/c_interface/standalone_c/Makefile:
Fix grammar in a couple of spots.
Use ':=' in place of '=' in some assignments.
samples/c_interface/standalone_c/c_main.c:
Fix grammar in a couple of spots.
Do not say that access to Mercury mutables from C is currently
not thread safe; it will never be thread without the programmer
putting in their own synchronization.
util/mkinit.c:
Delete the variable "init_suffix", which has never been used.
(It was added in commit 04e614485, where it was merged on to the then CVS
trunk from the deep2 branch.)
doc/mercury_reference_manual.texi:
Fix spelling and grammar.
Expand "iff" to "if and only if".
Use "choice point" consistently in the text instead of a mixture
of that and "choicepoint".
