This first step deals with the consequences of such removal.
The removal itself will happen in stage 2. That step will
add "is" to the prolog module in the library.
compiler/add_pred.m:
Prepare for "is" being in the prolog module.
compiler/options.m:
Add a way to test whether the change to add_pred.m is in the
installed compiler.

Replace calls to "is" with unifications. In many places,
bring programming style up to date.
compiler/module_qual.m:
The interface of a module A contains items (e.g. predicate declarations)
that refer to entities such as types, insts, modes etc. They may refer
to those entities if (a) they are defined in the interface of module A,
(b) in a parent module of module A, or (c) if they are imported from
another module, module B, which is imported into module A in the interface
of module A.
The old algorithm that attempted to enforce this requirement had a basic
design fault: it based the decision as to whether the use of an entity
in the interface was legal solely on the name of the module that defined
that entity. This correctly implements tests (b) and (c), but it does
not even attempt to implement the interface test part of (a).
It therefore allowed exported items to refer to nonexported entities.
This diff changes the whole design approach to the test. Instead of
keeping a list of modules *all* of whose entities may be used in the
interface of the current module, record for *every* entity whether
it may be used in the interface. Set the permissions differently
in the interface and implementation sections of the current module.
Improve the formatting of the ambiguity error message.
NEWS:
Announce the stricter enforcement of the documented language rules,
in a new section for potentially compatibility-breaking changes.
compiler/check_typeclass.m:
Delete a test for a special case of the situation that module_qual.m
now tests for. If this problem occurs, module_qual.m will pick it up,
and check_typeclass.m will never even be invoked, so this copy of the test
can never succeed.
library/hash_table.m:
Fix code that violated the language rules: we export a type that
includes another type, but didn't export the second type. We now do.
browser/declarative_analyser.m:
browser/declarative_edt.m:
compiler/coverage_profiling.m:
Fix code that violated the language rules. We used to export predicates
and functions whose argument types included nonexported types. As it
happens, none of those predicates and functions actually need to be
exported, so keep them private.
In coverage_profiling.m, don't abstract export a type that is not
used outside the module, and give a function a name that doesn't
clash with a type name.
tests/invalid/bug17.{m,err_exp}:
A new test case to test the error message we get if the module interface
refers to a nonexported type.
tests/invalid/bad_instance.err_exp:
This test case used to get two kinds of errors, one of which was
the illegal use of nonexported type in an exported abstract instance
declaration. We now discover this error earlier, and stop after we
do so. Update the expected error message.
tests/invalid/bad_instance2.{m,err_exp}:
New test case: a modified copy of bad_instance.m, testing the other
kind of error originally tested by bad_instance.m.
tests/invalid/instance_no_type.err_exp:
Update the expected error message.
tests/invalid/Mmakefile:
Enable the new test cases.

tests/warnings/unused_args_test.m:

the type that previously, we illegally used in the module interface.
tests/recompilation/add_type_re.err_exp.2:
Expect the updated ambiguity error message.

Make these tests use four-space indentation, and ensure that
each module is imported on its own line. (I intend to use the latter
to figure out which subdirectories' tests can be executed in parallel.)
These changes usually move code to different lines. For the debugger tests,
specify the new line numbers in .inp files and expect them in .exp files.
Estimated hours taken: 0.25
Branches: main
tests/benchmarks/*.m:
Move the declaration of main1/3 back into the interface section,
so that the instructions on how to "test the performance of the
benchmarks" in the Mmakefile still work. These predicates need
to be exported so that they can be used as entry points for
benchmarking.
Estimated hours taken: 0.2
Branches: main
tests/benchmarks/*.m:
Make these files conform to our coding conventions by putting predicate
declarations immediately before predicates.
Estimated hours taken: 0.25
Fix unique mode errors in the benchmark tests.
tests/benchmarks/{cqueens,crypt,queens,query}.m:
Change the determinism of main from `multi' to the new `cc_multi'.
tests/benchmarks/{deriv,deriv2}.m:
Rearrange the code slightly to move the I/O
out of the condition of an if-then-else.
tests/benchmarks:
Modify the nondet/semidet benchmarks so that `main' is either
det or multidet.
Remove files `Entry' and `NP_Entry' since they are no longer
needed.
