Make an error message more inclusive.
compiler/comp_unit_interface.m:
When we cannot generate a .int0/.int/.int2 file because of file access
issues, the reason is *usually* that we can't read a .int3 file.
However, it is also possible that the reason is that we can't read
a .int0 file, so include that possibility in the overall error message.
(The "can't read this file" message, with the specifics of the file
that couldn't be read, would have been printed earlier.)
tests/invalid_make_int/missing_parent_import.int_err_exp:
tests/invalid_make_int/sub_c.int_err_exp:

Move code to generate interface to comp_unit_interface.m.
compiler/write_module_interface_files.m:
compiler/comp_unit_interface.m:
Move the predicates that generate the parse trees of interface files
from write_module_interface_files.m to comp_unit_interface.m.
Move the types they need with them, and document them.
Rename the predicates involved to make clear whether they generate
parse trees, write them out, or both.
In comp_unit_interface.m keep private the previously exported predicates,
because their only callers are the moved predicates, so all calls them
are now local to the module.
compiler/make.get_module_dep_info.m:
compiler/mercury_compile_main.m:
Conform to the changes above.

compiler/comp_unit_interface.m:
Add use_module declarations for modules referenced by the right hand sides
of equivalence type definitions to the implementation sections of .int2

accumulate_modules_in_qual_type, which do *almost* the same job,
as similar to each other as possible.

Separate marker pragmas from other decl/impl pragmas.
compiler/prog_item.m:
Previously, both decl and impl pragmas contained some pragma kinds
that contained only the specification of a predicate or function.
These served only to specify a marker to be applied to the named
predicate or function.
This diff separates out those kinds of pragmas from the types of
both the decl pragmas and the impl pragmas (the difference is that
decl pragmas may appear in module interfaces, while impl pragmas may not),
and gives them two new representations: decl markers and impl markers.
While in the old representation, each kind of marker had its own wrapper
around the predicate/function specification, in the new representation,
they are side-by-side, which allows simpler construction techniques
and smaller code.
Update the definition of parse_tree_module_src, parse_tree_plain_opt,
parse_tree_int0 and parse_tree_int1 to include markers alongside
pragmas of each kind. Use subtypes to restrict the kinds of markers
that can appear in parse_tree_plain_opts to the set that we actually
can put into them. (Source files of course can contain any markers,
and .intN files either get put into them either all of the markers
that occur in the source file in a given section, or none of them.)
Delete the item_pragma_info type, which was a wrapper around
the specific info of each pragma, and stored a context and an item
sequence number alongside it. Move the context and the item sequence
number into the representation of each pragma. This should reduce
visual clutter in the source code at places that construct or deconstruct
pragmas, and at runtime (with direct args) it should reduce both
the number of memory cells we need to allocate, and the number
of pointers we need to follow.
Include decl vs impl in the names of some function symbols.
Partly to counteract that, shorten some names to avoid excessive
line lengths.
compiler/add_pragma.m:
Add predicates to add decl and impl markers.
Move the predicates looping over lists of pragma next to the
predicates handling those pragmas.
compiler/make_hlds_passes.m:
Add both decl and impl markers before adding foreign_procs.
The ability to do this was the original motivation for this diff.
Update the comments both about this issue, and about why we delay
adding tabling pragmas to the HLDS.

Conform to the changes above.
Add an XXX about something fishy.

Make foreign_procs their own top-level item kind.
compiler/prog_item.m:
Change foreign_procs from being one kind of impl_pragma item
to being their own item kind. Because of this, the changes to
some of the modules listed below delete "pragma" from the names
of predicates and types referring to foreign_procs.
Include foreign_proc items in parse_tree_module_srcs and
parse_tree_plain_opts, the two kinds of parse trees that may contain
foreign_procs.
compiler/make_hlds_separate_items.m:
Gather foreign procs independently of impl pragmas.
compiler/make_hlds_passes.m:
Add foreign_procs from the parse_tree_module_src and any
parse_tree_plain_opts to the HLDS at the same time as we add
foreign_procs generated by the compiler to implement solver types
and mutables. Document the reason for this.
Document also the reason why we should add all marker pragmas
just before we do this. Document the reason why two tests will fail
until that, or something similar, is done.
compiler/add_foreign_proc.m:
Delete a test that was required only because we couldn't guarantee
the relative order of adding foreign_procs and pragmas that mark
predicates as external on one backend.

Use abstract typeclasses in parse_tree_int[13].
compiler/prog_data.m:
Define a subtype of the typeclass interface type for abstract typeclasses.
compiler/prog_item.m:
Change the types of the fields representing
- implementation section typeclasses in .int files, and
- interface section typeclasses in .int3 files
to a subtype that allows the definition of only abstract typeclasses.
The interface section typeclasses in .int3 files have more invariants
than just being abstract, but these cannot currently be expressed
using subtypes.

Delete mer_inst's abstract_inst functor.
We have never supported abstract insts, and we are not likely to start
using them any time soon, but we have had them in the representation of insts
since the beginning. Since they were never actually generated, the code
that operated on them was never really tested, which is good, because
in many places, that code simply threw an exception. The code that didn't
throw an exception when it found an abstract inst had to work correctly
for the abstract_insts that we actually generated, which were abstract
only in the sense that they were references to a would-be user-defined inst
name that wasn't actually defined.
There were two sources of such "abstract" insts.
- One was failed calls to inst_lookup that specified an user_inst inst_name.
- The other consisted of predicates whose job was to construct error messages
involving insts. These either converted cons_ids into abstract insts,
or mangled valid user_inst inst_names into invalid user_inst inst_names,
because error_msg_inst.m generated good-looking messages when given
the results of such conversions.
The first is handled by the fact that module qualification detects and
reports references to undefined insts and modes, and does not let the
compiler proceed to the compiler phases that may call inst_lookup.
The second is handled by the changes to error_msg_inst.m below.
These change to handle the use cases of the two error-message-constructing
predicates that used to employ abstract_insts, but now employ user_inst
defined_insts with a two particular kinds of undefined inst ctor,
one for each use case.
compiler/prog_data.m:
Delete the abstract_int function symbol from the mer_inst type.
compiler/inst_lookup.m:
When the lookup of an user_inst inst_name inside a defined_inst
fails, don't convert that defined_inst into abstract inst,
throw an exception.
compiler/error_msg_inst.m:
Add code to deal with the insts that add_mutable_aux_preds.m and
mode_errors.m generate for us to convert to lists of error message pieces.
The addition is done twice, in an as identical a fashion as possible,
when generating non-inline pieces and when generating inline pieces.

Delete module_names_contexts fields from parse trees.
compiler/prog_item.m:
We used to include information about include_module, import_module
and use_module declarations in a module in the parse_tree_module_src
in two forms: an unchecked form, which had type module_names_contexts,
and a checked form, which had types include_module_map and
import_and_or_use_map respectively. We have been gradually switching
more and more code working on parse trees from taking the unchecked form
as input to taking the checked form as input.
This diff completes the process.
- It deletes the ptms_{int,imp}_includes and ptms_{int,imp}{imports,uses}
fields from parse_tree_module_src. Their checked versions remain.
- It changes the parse_tree_int3 type to store include and import
information using checked rather than unchecked types. The reason
why this wasn't done before is that the checked data structures
could not preserve the relevant invariants until subtypes were added
to the language. This diff thus also defines the needed new subtype.
Fix a typo (wrong int file number) in a field name.
compiler/item_util.m:
Add some utility predicates needed by new code in the modules below.
Change the interface of a utility predicate
- to stop requiring the caller to supply unchecked data structures,
constructing them internally as intermediate data structures instead,
and
- to stop returning some now-unneeded unchecked data structures.
Keep some utility predicates private that are no longer needed
outside this module.
Delete a whole bunch of utility predicates which are no longer needed
at all.

Don't generate duplicate instance declarations.
We used to include in the .int0 file the abstract form of all the instance
declarations in both the interface and the implementation sections.
When an instance is declared (in an already-abstract form) in the interface
section and defined in the implementation section, this resulted in the
abstract interface declaration being included in the .int0 file twice,
once in the interface section, and once in the implementation section.
compiler/comp_unit_interface.m:
Fix this by including an abstract instance declaration in the
implementation section of a .int0 file only if it does not also appear
in the interface section.
Conform to the changes in prog_item.m below.
compiler/parse_tree_out.m:
To help implement the above test, add a function to return the string
form of an abstract instance declaration.
It is easy to make this change for *abstract* instance declarations,
but not *concrete* instance definitions, because (in order to handle
instances that define methods by clauses, instead of by pred/func names)
the latter would require generalizing *all* the code for writing out
clauses, with all the overhead associated with replacing first order calls
with method calls.
Another change (unrelated to the problem above) is to write out
typeclass and instance definitions for typeclasses with no methods
in a nicer form. Instead of looking like this:
:- instance classname(argtypes) where [
].
they now look like this:
:- instance classname(argtypes) where [].
Another formatting change unrelated to the above: don't put parentheses
around typeclass names in instance declarations/definitions if the name
is all alphanumeric and not an operator.
Conform to the changes in prog_item.m below.
compiler/prog_data.m:
compiler/prog_item.m:
To be able to use the new code to convert abstract instances to strings
in comp_unit_interface, and to write out abstract instance declarations
inside .int0 (and other .intN) files, it helps to know which instance
items can only be abstract in these files. As it turns out, none can be
concrete. So define a subtype of item_instance_info that can contain
only abstract instance declarations, and use it to replace
item_instance_info in parse_tree_intN for all N.
compiler/parse_tree_out_info.m:
Add a utility function for new code in comp_unit_interface.m
invoking new code in parse_tree_out.m.
compiler/convert_parse_tree.m:
Conform to the changes in prog_item.m by insisting that instances
read in from .intN files are all abstract.

tests/invalid/instances_pc.instances_pc_helper_1.err_exp:
Expect a reference to only ONE old instance declaration in
instances_pc.int0. Expect it at a new line number, due to the first
formatting change above.

Delete include context maps from parse_tree_int[012].
compiler/prog_item.m:
We used to record information about include declarations
in parse_tree_int[012] in two forms:
- as a pair of maps from module names to contexts (one each for
includes in the interface and implementation sections), and
- as a single map from module names to an include_module_info, which
recorded the section of its appearance along with its context.
The second of these data structures is derived from the first,
in a process that can result in the generation of diagnostic messages.
In the absence of any issues reported by these diagnostics, the two forms
contain the same information.
Avoid this redundancy by keeping only the second form in the parse trees
of .int0, .int and .int2 files. (.int3 files cannot contain include_module
declarations.)
Since .int2 files may contain include_module declarations only in
the interface section, change the representation of the second form
to a type that expresses this invariant: int_include_module_map,
which is a subtype of the existing type include_module_map.

Delete import/use context maps from parse_tree_int[012].
compiler/prog_item.m:
We used to record information about import and use declarations
in parse_tree_int[012] in two forms:
- as a quartet of maps from module names to contexts (one each for
int imports, int uses, imp imports and imp uses), and
- as a single map from module names to a section_import_and_or_use,
which recorded the section and kind (import or use) of its appearance
along with its one context, except for the case of modules that have
an use_module declaration in the interface section and an import_module
declaration in the implementation section.
The second of these data structures is derived from the first,
in a process that can result in the generation of diagnostic messages.
In the absence of any issues reported by these diagnostics, the two forms
contain the same information.
Avoid this redundancy by keeping only the second form in the parse trees
of .int0, .int and .int2 files. (For .int3 files, which can contain
only import_modules, and only in the interface section, this redundancy
has not been present even before now.)
Since .int and .int2 files may contain only use_module declarations
and not import_module declarations, change the representation of the
second form to a type that expresses this invariant: the new type
section_use_map, which is a subtype of the existing type
section_import_and_or_use_map.
For .int2 files, we could use an even tighter type right now, but
a fix for Mantis bug #563 would have to undo such a change, so
don't bother.

Don't provide for implicit imports in .intN parse trees.
compiler/prog_item.m:
The ptiN_import_use_map fields in the representations of .int0, .int
and .int2 files had the same type as the ptms_import_use_map field
in the parse trees of .m files, which is where they were derived from.
However, while the ptms_import_use_map field needs to be able to represent
implicit imports, the parse trees of .int0, .int and .int2 files
should never include any implicit imports, and in fact any implicit
imports in these fields were already ignored.
Encode the invariant that interface files never include implicit imports
in the types of these fields.

Split up error_util.m into five modules.
compiler/error_spec.m:
This new module contains the part of the old error_util.m that defines
the error_spec type, and some functions that can help construct pieces
of error_specs. Most modules of the compiler that deal with errors
will need to import only this part of the old error_util.m.
This change also renames the format_component type to format_piece,
which matches our long-standing naming convention for variables containing
(lists of) values of this type.
compiler/write_error_spec.m:
This new module contains the part of the old error_util.m that
writes out error specs, and converts them to strings.
This diff marks as obsolete the versions of predicates that
write out error specs to the current output stream, without
*explicitly* specifying the intended stream.
compiler/error_sort.m:
This new module contains the part of the old error_util.m that
sorts lists of error specs and error msgs.
compiler/error_type_util.m:
This new module contains the part of the old error_util.m that
convert types to format_pieces that generate readable output.
compiler/parse_tree.m:
compiler/notes/compiler_design.html:
Include and document the new modules.
compiler/error_util.m:
The code remaining in the original error_util.m consists of
general utility predicates and functions that don't fit into
any of the modules above.
Delete an unneeded pair of I/O states from the argument list
of a predicate.
compiler/file_util.m:
Move the unable_to_open_file predicate here from error_util.m,
since it belongs here. Mark another predicate that writes
to the current output stream as obsolete.
compiler/hlds_error_util.m:
Mark two predicates that wrote out error_spec to the current output
stream as obsolete, and add versions that take an explicit output stream.
compiler/Mercury.options:
Compile the modules that call the newly obsoleted predicates
with --no-warn-obsolete, for the time being.
compiler/*.m:
Conform to the changes above, mostly by updating import_module
declarations, and renaming format_component to format_piece.

Tighten representation of include/import/use decls.
compiler/prog_item.m:
Change the representation of include, import and use declarations
in the data structures of .int0 and .int3 files.
For both .int0 and .int3 files, switch from data structures that can
associate one or more contexts with each such declaration with
data structures that can associate just one. Any duplicates would be
errors, and we don't want to allow the representation of errors in
compiler-generated interface files. (Similar updates to .int/.int2
files are coming soon.)
For .int3 files, delete two fields that hold information about include
declarations and import/use declarations respectively in a fully checked
form. They are not needed, because with invariants that .int3 files
are subject to (no uses, no implementation section, no implicit imports),
they contain just the same info as the new data structures mentioned
in the paragraph above.
compiler/comp_unit_interface.m:
Update the code that computes the contents of .int0/.int3 files.
Fix some out-of-sequence variable names.
compiler/convert_parse_tree.m:
Update the code that converts the generic parsed representation of
interface files to the specific representations of .int0/.int3 files.
compiler/item_util.m:
Update the utility predicates that comp_unit_interface.m and
convert_parse_tree.m use to do their jobs. Add new variants
of some existing predicates.

Use checked types/insts/modes in parse_tree_module_src.
This means that we can do the exact same checks (and, if needed, generate
the exact same error messages) when generating interface files as when
generating target language code.
This should also allow us to simplify the process of adding type, inst
and mode definitions to the HLDS.
compiler/prog_item.m:
As above.
Delete unused function.
compiler/error_util.m:
Add mechanisms that allow us to distinguish (a) error specs that represent
a type, inst or mode name definition being invalid, from (b) other error
specs.
compiler/check_type_inst_mode_defns.m:
Improve the error messages we generate, in several ways.
First, for each message, specify a real severity. When the messages
could be seen only when generating interface files, making them all
warnings was fine and preserved old behavior, but since soon these
will be the only place for these checks, we need to call errors errors.
Second, specify, in the phase, which errors represent a invalid type,
inst or mode definition, and which don't.
Third, improve the wording of messages. In some places, do this by
being clearer about the distinction between declarations and definitions.
In others, do it by including more information in the message. In yet
others, do it by recovering some kinds of mistakes (mostly items being
in the wrong section) enough to avoid avalanche errors.
Fourth, fix a bug. If a type ctor has an exported *declaration*,
then it is ok for any foreign type definitions for that type_ctor
being in the implementation section, but if the type_ctor has an
exported Mercury *definition*, then any foreign_type definitions
must be in the interface section as well. The code that handled
both these situations did not enforce that.
Fifth, fix another bug: do not include foreign type definitions
in the source definitions of a type_ctor twice, once as a "du" (sic)
definition, and once as itself.
compiler/convert_parse_tree.m:
Check type, inst and mode definitions in raw_compilation_units

Separate subtypes from du types in parse trees.
compiler/prog_data.m:
Split type_details_sub from type_details_du, and separate
parse_tree_sub_type from parse_tree_du_type. This gets us two things:
- It allows us to encode the prohibition on user-specified equality and
comparison predicates, and "where direct_arg is" clauses,
on subtype definitions.
- It gives us data types we can use to represent (a) only subtype
definitions, and (b) only non-subtype du definitions.
Note that this diff deliberately leaves the HLDS representation
of subtypes unchanged. This is because while a subtype *definition*
may not specify e.g. equality and comparison predicates, a subtype *can*
have equality and comparison predicates; it just has to get them from
its base type. And the same applies to direct args.
compiler/parse_type_defn.m:
Enforce the invariant that subtypes may not have user-specified equality
and comparison predicates, or "where direct_arg is" clauses.
If we find a subtype definition that does have one or both of these
non-allowed and now-nonrepresentable components, we do still want to
return the rest of the type definition, in order to avoid misleading
error messages about that type having no definition at all. To make this
possible, allow the parsing predicate to return error_specs "alongside",
as well as "instead of", the item or marker being parsed.

Use checked type/inst/modes in parse_tree_int[123]s.
With this change, we guarantee that if any type, inst or mode
has inconsistent definitions in its defining module, those inconsistencies
will not make it into the the module's .int/.int2/.int3 files, where
they would confuse any compiler invocation that reads them in.
compiler/prog_item.m:
Replace {type,inst,mode}_ctor_defn_maps, which are unchecked,
with {type,inst,mode}_ctor_checked_maps in parse_tree_int[123]s.
To make this possible,
- generalize the items containing inst and mode definitions the way that
items containing type definitions have been generalized previously,
to allow them to store particular *kinds* of inst or mode definitions;
- move the definitions of type_ctor_checked_map and its components
here from check_type_inst_mode_defns.m; and
- add similar, but simpler, definitions for {inst,mode}_ctor_checked_map.
compiler/check_type_inst_mode_defns.m:
Delete the type definitions moved to prog_item.m.
Modify the checking process slightly to allow it to check properly
the definitions we now put into .int, .int2 and .int3 files.
Add code to check inst and mode definitions as well as type definitions.
Since insts and modes have only one non-abstract kind of definition,
these codes are much simpler than the code for checking types.
compiler/comp_unit_interface.m:
Construct checked type, inst and mode definitions to put into
.int, .int2 and .int3 files. The .int2 and .int3 parts were
reasonably simple, but the .int part requires some detailed
case-by-case analysis.
compiler/convert_parse_tree.m:
Check the type, inst and mode definitions read in from .int/.int2/.int3
files when creating their parse trees. If those files were generated
by a compiler that has this diff, then this checking process should
not find any problems.
compiler/equiv_type.m:
Operate on checked type, inst and mode definitions instead of their
unchecked versions.
Delete an unneeded field from a structure.
compiler/error_util.m:
Add {qual,unqual}_{inst,mode}_ctor as format components, so that
any error messages about inst and mode definitions do not have to convert
inst_ctors and mode_ctors to symname/arity pairs.
compiler/item_util.m:
Add some utility predicates and functions needed by the changes above.
compiler/module_qual.collect_mq_info.m:
Since checked type, inst and mode definitions can contain info that is
derived from both the interface and implementation sections of a module,
add the capability to get only the *publicly* declared types, insts and
modes from their respective kinds of checked definitions.
compiler/module_qual.qualify_items.m:
Module qualify checked type, inst and mode definitions.
compiler/module_qual.qual_errors.m:
Treat references to inst_ctors and mode_ctors in qualification error
messages the same way as we treat type_ctors.
Also replace mq_ids that are intended to represent classes with class_ids,
to represent the intent better.

Don't put duplicate imports/uses in .int{,0,2}.
The problem addressed by this diff is that copying any duplicate
import_module and/or use_module declarations in .m files to
automatically generated .intN files will cause those errors to be
reported 1+M times, once when compiling the source module, and
once for each of the M modules that import it. Those extra M reports
are not useful; they are only clutter.
compiler/comp_unit_interface.m:
Do not copy the raw set of import_module and use_module declarations
from the source file to the .int0 file. Instead, compute them anew
from the import_and_or_use map, which was built by discarding any
duplicate declarations, either within a single section, or across
both sections.
When deciding which modules to generate a use_module declaration for
in the implementation section of a .int or .int2 file, do not include
one for any module which has a use_module declaration in the interface.
compiler/item_util.m:
Add a predicate that comp_unit_interface.m uses in the first task above.

In some cases, this means passing around aug_make_int_units instead of
aug_compilation_units.
In a few cases, it means creating two copies of a predicate,
one for aug_compilation_units and one for aug_make_int_units.
In such cases, factor out any commonalities between the copies.
In many cases, it means updates to account for the specialized types
of the fields of aug_compilation_unit or aug_make_int_unit.
In some cases, it means deleting code that was always unreachable,
but the not-tight-enough types did not make this fact visible.
(Due to this effect, this diff removes more lines than it adds.)

Break a source file info parse_tree_module_srcs ...
... instead of into raw_compilation_units. Besides being more convenient to
work on, a parse_tree_module_src encodes in its type a significant number
of invariants that a raw_compilation unit does not.
compiler/split_parse_tree_src.m:
Immediately after creating a raw_compilation_unit for one of the modules
in a potentially multi-module source file, convert it to a
parse_tree_module_src.
Fix an old problem that can come up in contrived erroneous code.
Specifically, when a submodule is both nested inside its parent module,
*and* it also has an explicit include_module declaration, we used to
record the contexts of both "inclusions", after generating an error
message. The more rigorous checking that later code now does on the
resulting inclusion map would look at this "duplicate inclusion"
and generate *another* error message. To avoid this redundant message,
do not record the contexts of erroneous inclusions for which a message
has already been generated.
compiler/grab_modules.m:
Operate on parse_tree_module_srcs instead of raw_compilation_units.
This allows us to avoid having code for doing what converting the
raw_compilation_unit to a parse_tree_module_src has already done.
In fact, that conversion code does a better job. The old code assumed
that all implicitly available modules are used in the interface,
whereas in fact only some should be used in the interface, with
the rest being used in the implementation section.
compiler/module_imports.m:
Make the predicates that create module_and_imports structures
take a parse_tree_module_src instead of a raw_compilation_unit
as input. For now, we convert the parse_tree_module_src back to
a raw_compilation_unit for further processing, but I intend
a later diff to change this. Nevertheless, one immediate change
is that init_module_and_imports now stores the *actual*
parse_tree_module_src in the module_and_imports structure,
not a dummy.
compiler/prog_item.m:
Do not include a list of foreign_enum items in the interface section
of a parse_tree_module_src, since such items are not allowed to occur
in interface sections.
For the same reason, delete the field for foreign_enums in the interface
sections of .int0 and .int files.

A start on getting type_repn info from .int files.
compiler/du_type_layout.m:
Add a first draft of the code that will eventually get type representation
information from .int files. Invoke the new code only if undocumented,
developer-only experiment flags are set, and when invoked, compare
its output with the output of the old algorithm it is intended to
eventually replace.
The new code is not yet complete, and thus has not yet been tested.
compiler/prog_item.m:
Add a new field to the augmented compilation unit data type
that is intended to hold the .int file of the main module, the module
that the augmented compilation unit is for. For every module imported
by the main module, we read its .int or .int2 file and get the
representation information for the types they define from those files,
but we need this info for the main module's own types as well.
Add "need type representation information" as reason for reading
a .int file.
Break some types down into smaller types, to allow their components
to be manipulated individually by du_type_layout.m.
Start using uint8, not uint, in situations where we want to store
values that select bits in words, which fit into 6 bits.
Add XXXs where we could, and maybe should switch to uint8s.
Add extra documentation.
compiler/grab_modules.m:
Read in the main module's own .int file.
Replace a bool with a bespoke type.
compiler/module_imports.m:
Provide a slot for the main module's own interface file,
which will be used to set the new slot in augmented compilation units.
compiler/comp_unit_interface.m:
Put the exact same type_ctor_repn_map into .int2 files as .int files.
This should prevent the scenario where a compilation reads
e.g. mod_x.int2, gains access to the definitions of the exported types
of module mod_x, but then needs to read mod_x.int as well to find out
how those types are represented. Since neither type checking nor any
other semantic analysis pass pays any attention to type_repn items,
the additional type_repn items in mod_x.int2 cannot turn an otherwise
illegal program into a legal one.
compiler/hlds_data.m:
Clarify a comment.
compiler/maybe_error.m:
Provide a utility predicate.

Simplify the logic of prog_mutable.m.
compiler/prog_mutable.m:
The old logic was complicated by the need to have some decisions
made by prog_mutable.m and some by add_mutable_aux_preds.m,
which had different tasks (generating public declarations
vs generating both public and private definitions), and thus
used different approaches.
Replace this with code in which for each kind of auxiliary predicate,
the code to generate its declaration is just before the code
to generate its definition. And the code that decides what public
declarations to generate is just before the code that decides
what public and private definitions to generate.
Make this latter logic operate as directly as possible on the mutable's
attributes, instead of first calling a separate predicate to compute
the set of auxiliary predicates the mutable needs, recording the results
in the mutable_target_params structure, and then generating definitions
as directed by this structure.
To make this possible, split some existing predicates that used
to do two related but nevertheless separate jobs, such as defining
get and set predicates for both constant and nonconstant mutables.
Give a bunch of predicates names that better reflect whether they
generate declarations only, definitions only, or both.
Consistently refer to the name of the mutable as MutableName,
since the code handles the names of other kinds of things as well.
Give some predicates slightly shorter names, so calls to them
fit on just one line.

from prog_mutable.m, which is part of the parse_tree package, and thus
should not import anything from the hlds package.

Switch to structured item sequence numbers.
compiler/prog_data.m:
Define a data type that encodes the distinction between valid
and dummy item sequence numbers in the type. Previously, different
parts of the compiler expressed this distinction in two different ways,
either using "-1" to represent a dummy sequence number, or using "no"
in a maybe(int) type.

Use the new type instead of plain "int" as the sequence number in items.

cur_user_decl_info in a pred_info does NOT guarantee a valid
item sequence number.

----------------
runtime/mercury_type_info.h:
Add a flag in MR_TypeCtorInfo to indicate if the enum/du layout
array may be indexed by an enum value or du ptag value.
Subtypes break the invariant that the layout array contains entries
for every enum/ptag value from 0 up to the maximum value.
The presence of the flag MR_TYPE_CTOR_FLAG_LAYOUT_INDEXABLE tells
the runtime that it can directly index the layout array instead of
searching through it (which is the common case, for non-subtypes).
Add a field MR_du_ptag to MR_DuPtagLayout. This is necessary to find
an entry for a given primary tag value in a MR_DuPtagLayout array.
Add a field MR_du_ptag_flags to MR_DuPtagLayout, currently with one
possible flag MR_DU_PTAG_FLAG_SECTAG_ALTERNATIVES_INDEXABLE.
As with primary tags, subtypes break the invariant that the
sectag_alternatives array contains entries for every secondary tag
value from 0 up to the maximum value. The presence of the flag tells
the runtime that it can directly index the sectag_alternatives array
(which is the common case, for non-subtypes).
The two fields added to MR_DuPtagLayout occupy space that was
previously padding, so the size of MR_DuPtagLayout is unchanged.
In MR_EnumFunctorDesc, replace the MR_enum_functor_ordinal field by
MR_enum_functor_value, i.e. the integer value representing the
functor in memory. Storing *both* the functor ordinal and enum value
would increase the size of the MR_EnumFunctorDesc struct, and would
be redundant in the common case of non-subtype enums (both fields
would contain equal values). We forgo having the functor ordinal
directly available, at the cost of needing to search through an
MR_EnumFunctorDesc array when a functor ordinal is required for a
subtype enum, which should be rare.
compiler/rtti.m:
Swap enum "functor ordinal" and "value" in places.
Use a type 'enum_value' to try to ensure we do not mix up enum
functor ordinals and enum values.
Add code to encode the MR_TYPE_CTOR_FLAG_LAYOUT_INDEXABLE flag.
Add code to encode the MR_DU_PTAG_FLAG_SECTAG_ALTERNATIVES_INDEXABLE
flag.
compiler/rtti_out.m:
Write out "enum_ordinal_ordered_tables" ordered by functor ordinals
instead of "enum_value_ordered_tables" ordered by enum values.
Output the enum value for MR_EnumFunctorDesc instead of functor
ordinal.
Output the MR_du_ptag and MR_du_ptag_flags fields for
MR_DuPtagLayout.
Relax sanity check on primary tags. A subtype may not necessarily
use ptag 0, and may skip ptag values.
compiler/rtti_to_mlds.m:
Generate "enum_ordinal_ordered_tables" instead of
"enum_value_ordered_tables".
Fill in the enum value for a MR_EnumFunctorDesc instead of
the functor ordinal.
compiler/type_ctor_info.m:
Add predicate to generate the MR_du_ptag_flags field.
Add the MR_TYPE_CTOR_FLAG_LAYOUT_INDEXABLE flag to type_ctor_infos
when appropriate.
Bump the type_ctor_info_rtti_version.
----------------
runtime/mercury_ml_expand_body.h:
Search through an enum layout array to find the matching enum value,
unless the array can be indexed.
Search through a ptag layout array to find the matching ptag value,
unless the array can be indexed.
Search through a sectag_alternatives array to find the matching
secondary tag value, unless the array can be indexed.
Factor out the code to search through a foreign enum layout array
into a separate macro.
runtime/mercury_construct.c:
runtime/mercury_construct.h:
Add a functor_ordinal field to the MR_Construct_Info_Struct.
This will hold the functor ordinal now that it is not available in

functor_ordinal field needs to be filled in properly. Most callers
do not need the field.

This is the first step towards implementing a subtypes feature.
It introduces type definitions of the form
:- type subtype =< supertype ---> body.

that share "base types" using a coerce operation.

Put type_repn items for complex types into .int files.
compiler/decide_type_repn.m:
Previously, this module computed type_repn items to put into .int3 files
for a subset of the type constructors defined in the current module:
the direct_dummy, enum and notag types (the *simple* types),
and the du types whose representation is guaranteed to be
a word-aligned pointer when targeting C. (We care about pointers
being word-aligned only when applying the direct arg optimization.
This optimization is applicable only with the low level data
representation, which we use only when targeting C.)
This diff adds code to decide the representations of *all* the
type constructors defined in the current module.
This code is based on the existing code in du_type_layout.m,
which it is intended to eventually replace, but its job is more general,
because it decides the representation of each type not just for
one platform (the one we want to generate code), but for all possible
platforms. This is because we want to put the descriptions of type
representations into the module's .int file to serve as a single source
of truth for all modules that use the types defined in this module,
and the contents of .int files should be platform-independent.
For our purposes, there are six kinds of platforms, which are
distinguished along three axes: 64 vs 32 bit machines, spf vs non-spf
grades, and direct arg optimization enabled vs disabled. That is eight
combinations, but on 64 bit machines, a float takes up one word whether
that float is single or double precision, so two combinations aren't valid.
Some of the change to this module consists of generalizing the existing
code so that it can decide simple types not just when targeting .int3 files
but .int files as well. However, the bulk of it is code for deciding
the representations of non-simple types. The code is not lifted straight
from du_type_layout.m. There are two main kinds of changes.
First, I took the opportunity to simplify the algorithms used.
For example, while du_type_layout.m passes over each function symbol
in the most general kind of type twice: once to assign it a cons_tag,
and once to decide how to pack its arguments, the code here does both jobs
in one pass. Another example is that for historical reasons,
du_type_layout.m computed the amount of space needed for an argument
in one place for sub-word-sized arguments, and in another place
for more-than-word-sized arguments; decide_type_repn.m does it all
in one place.
Second, since we compute a representation for each type six times,
I tried to avoid obvious inefficiencies, but only if the code
remained simple. In the future, we may want to use an approach
based on the idea that in the process of computing the first
representation, we look out for any indication that the representation
may be different on any of the other five platforms, and if not,
we just reuse the first representation on the other five platforms as well.
However, that would be appropriate only *after* we have a simpler
system that has proven to work in practice.
There is a third, smaller change: when deciding whether an argument
is packable, we take into account not just equivalence type
definitions, but the definitions of notag types as well.
This takes advantage of the fact that if a notag type is abstract
exported, its representation is put into the relevant .int3 file
even though its definition isn't. (This is why du_type_layout.m
couldn't "see through" notag types: it couldn't depend on knowing
which types were notags.)
compiler/prog_item.m:
Change the types we use for type representation information.
Their previous definitions baked in the assumption that the only
distinction between platforms that mattered was the 64 vs 32 bit
distinction, which is not the case.
Use a more consistent naming scheme for the types we use
to represent type representation information.
Include the "dereferenced" types of the arguments in functors'
representations. (I use "dereferencing" here to mean expanding
equivalence types and throwing away any notag wrappers.).
We don't need it when generating C code using the low level
data representation, but we do need it to create constructors
when generating e.g. Java code that uses the high level data
representation.
compiler/parse_type_repn.m:
Rewrite most of this module due to the changes in prog_item.m.
compiler/parse_tree_out_type_repn.m:
A new module containing the code for writing out type representations.
The original code used to be in parse_tree_out.m, but it has been
mostly rewritten. Partly this is due the changes in prog_item.m,
but partly it is to provide much more structured output for humans,
since this makes debugging so much easier.
compiler/parse_tree.m:
Add the new module to the parse_tree package.
compiler/parse_tree_out.m:
Delete the code moved to parse_tree_out_type_repn.m.
compiler/parse_tree_out_info.m:

(the default) and output for humans.
compiler/hlds_data.m:
compiler/prog_data.m:
Move the ptag type from hlds_data.m to prog_data.m, to make it
accessible in prog_item.m.
Add some documentation in prog_data.m.
compiler/comp_unit_interface.m:
If the experiment1 option is enabled, invoke decide_type_repn.m
to decide what type_repn items to put into the .int file we are
generating. Otherwise, maintain the status quo.
compiler/write_module_interface_files.m:
Pass the globals to comp_unit_interface.m so it can look up experiment1.
compiler/equiv_type.m:
Add a predicate for expanding equivalence types for use by
decide_type_repn.m. This predicate expands just one type,
but reports any use of circular equivalence types in that type.
Improve the error message for circular equivalence types by *naming*
the type constructors involved. To make this possible, pass around
sets of such type constructors instead of just a boolean saying
*whether* we have found *some* circular equivalence type.
Replace bools used as changed/unchanged flag with a bespoke type.
Standardize some variable names.
compiler/options.m:
Add the developer-only option --pack-everything, which, if set,
tells decide_type_repn.m to turn on all the packing options
that currently work. This is to allow the testing of decide_type_repn.m
in the eventual intended mode of operation, even if the various
allow-packing-... options used by du_type_layout.m are set to "no".

Put type_repn items into .int3 files.
compiler/comp_unit_interface.m:
We used to put type_repn items for the simple types defined in a module
into the module's .int3 file if the option --experiment1 was given.
Change this to *always* do this. (What makes a type "simple" is defined
in du_type_layout.m; roughly a type is simple if its representation
does not depend on the representation of any other type.) It is
from these type_repn items in .int3 files that we should be able to
compute type representations for *all* types when creating a module's
.int file.
Don't take a globals parameter, as it is no longer needed.
compiler/write_module_interface_files.m:
Don't pass a globals parameter.
compiler/options.m:
Add a synonym for --compiler-sufficiently-recent, so a later diff
to configure.ac can test for the presence of this functionality
in the installed compiler.

Get decide_type_repn.m to return a map.
It constructs the data it returns in maps (keyed on type_ctors),
but used to turn those maps into lists before returning them.
This was wasteful, as comp_unit_interface.m promptly turned them back
into the maps that decide_type_repn.m constructed those lists from.
compiler/decide_type_repn.m:
compiler/comp_unit_interface.m:
Get the data from decide_type_repn.m to comp_unit_interface.m
in the form of a map.

Avoid almost all conversions to parse_tree_int.
For a while now, we have been generating interface files into
file-kind-specific parse trees, but we then converted those into
the generic parse_tree_int type for further processing, because
the old code for doing that further processing operated on
parse_tree_ints. This diff replaces most of that "further processing"
code with code that operates on int-file-kind-specific parse trees,
thus avoiding the cost of conversion. The main cost is not performance
(the effect of this change on compiler speed is negligible), but loss
of code clarity through the loss of invariants.
compiler/comp_unit_interface.m:
After generating a parse_tree_intN for N in {0,1,2,3}, do NOT convert it
to a generic parse_tree_int.
When constructing a parse_tree_int3 from a raw_compilation_unit,
guard against a situation where we could unintentionally create
a duplicate of an abstract type definition. The solution here
is not the most elegant possible, but a better one requires other
changes that don't really fit in this diff.
compiler/canonicalize_interface.m:
Put two large blocks of code (dealing with the canonicalization
of pred and mode declarations respectively) into their own predicates.
Expose a mechanism to standardize not the contents of a whole
interface file, but just the predicate and mode declarations in it.
(These are the tricky kinds of items to canonicalize, because sorting
a set of mode declarations can change the meaning of the program.)
This mechanism is just a specialized version of the existing machinery.
Since this diff leaves the existing machinery unused, the next diff
will delete it, and since that will probably leave a too-small module,
delete the whole module, after moving the remaining small piece of code
to the only module that uses it, parse_tree_out.m.
compiler/parse_module.m:
Instead of implementing actually_read_module_intN in terms of
actually_read_module_int, do the reverse, which avoids the unnecessary
conversion from parse_tree_intN to parse_tree_int.
compiler/parse_tree_out.m:
Provide predicates, output_parse_tree_intN, to write out parse_tree_intN,
not just a generic parse_tree_int.
Change the existing service routines, mercury_output_parse_tree_intN,
that do all the work of the above new predicates to write out the contents
of each parse tree in the canonical order, using the newly exposed
functionality in canonicalize_interface.m where needed. (Previously,
write_module_interface_files.m invoked canonicalize_interface.m to do this
before calling parse_tree_out.m.)
These service routines were originally written for debugging; make them
suitable for creating proper .intN files by removing unneeded output.
compiler/write_module_interface_files.m:
Call the newly provided predicates in parse_tree_out.m to output
interface files. To make this possible, break up the old predicate
actually_write_interface_file into smaller predicates, so that the
new predicates actually_write_interface_fileN can each call whichever
of these are relevant for the given interface-file-kind. (Some pieces
are relevant to only a subset of these kinds.)
compiler/convert_parse_tree.m:
Note the reason why this diff is not deleting the functions that convert
parse_tree_intN to parse_tree_int.
compiler/read_modules.m:
Note the reason why this diff is not deleting the functions that read in
generic parse_tree_ints.
