Deprecate --no-ansi and --no-ansi-c.
--no-ansi (mgnuc) and --no-ansi-c (mmc) have not actually done anything for
many years now. Deprecate these options and remove their "use" throughout most
of the Mercury system. (The remaining uses are in the Makefiles for the Boehm
GC, which need to be updated separately.)
Also deprecate the internal compiler option --cflags-for-ansi.
compiler/options.m:
Document that --no-ansi-c is now deprecated.
Document that the internal option --cflags-for-ansi is now
deprecated.
compiler/compile_target_code.m:
Do not pass the ANSI options to the C compiler.
scripts/mgnuc.in:
scripts/mgnuc_file_opts.sh-subr:
Deprecate the --no-ansi option; delete code that no longer does
anything useful.
configure.ac:
Delete the configuration variable CFLAGS_FOR_ANSI; it is only ever
set to be empty. (The comment talks about --no-ansi doing other things
in the mgnuc script. It used to also cause some preprocessor macros
to be defined for compatibility with the system headers on some
platforms -- that has not been the case since 2013.)

Document that --no-ansi-c is deprecated.

Delete prog_out.m, moving its code to other modules.
compiler/parse_tree_out_cons_id.m:
Move the predicates and functions in prog_out.m that deal with cons_ids
to this module.
compiler/parse_tree_out_sym_name.m:
Move the predicates and functions in prog_out.m that deal with sym_names
and similar entities to this module.
compiler/parse_tree_out_type.m:
Move the predicates and functions in prog_out.m that deal with types
to this module.
compiler/parse_tree_out_misc.m:
Move the predicates and functions in prog_out.m that deal with simple
types to this module.
Delete mercury_output_det and mercury_format_det, replacing all their
uses with calls to mercury_det_to_string.
compiler/prog_out.m:
Delete this module.
compiler/parse_tree.m:
Delete prog_out from the parse_tree package.
compiler/Mercury.options:
compiler/notes/compiler_design.html:
Delete references to prog_out.m.
compiler/*.m:
Update imports and any explicit module qualifications to account
for the moved code.
tools/filter_sort_imports:
Automatically filter out any repeated imports. This can help with
changes like this that redistribute the contents of one module to other
modules. In this case, after a global replacement of prog_out's import
with the import of parse_tree_out_misc, this updated script could
remove this changed import from modules that already imported
parse_tree_out_misc.

Use explicit streams in analysis*.m.
compiler/analysis.m:

Switch to using explicit streams.
Use io.format when relevant.
Give some fields, predicates and variables more meaningful names.
Replace some rafe-isms with code in our usual coding style.
Add XXXs for possible future improvements.
Replace the flag that says whether debug is enabled with a maybe
wrapped around the stream where debug output should go.

Pass streams explicitly at the top levels.
compiler/mercury_compile_main.m:
compiler/mercury_compile_front_end.m:
compiler/mercury_compile_llds_back_end.m:
compiler/mercury_compile_make_hlds.m:
compiler/mercury_compile_middle_passes.m:
compiler/mercury_compile_mlds_back_end.m:
Pass progress and error streams explicitly in these top modules
of the compiler. Use "XXX STREAM" to mark places where we could switch
from using stderr for both the progress and error streams to using
module-specific files as the progress and/or error streams.
compiler/passes_aux.m:
Add a "maybe_" prefix to the names of the predicates that print progress
messages at the appropriate verbosity levels, as their printing of those
messages is conditional.
Provide versions of those predicates that take explicitly specified
streams to write to, and mark the versions that write to the current
output stream as obsolete.
The predicate that wrote progress messages for procedures
used to have two versions, one taking a pred_proc_id, and one taking
a pred_id/proc_id pair. Delete the latter, because the arity difference
that differentiated the two versions is now needed for the difference
between supplying and not supplying an explicit stream.
compiler/file_util.m:
compiler/hlds_error_util.m:
compiler/write_error_spec.m:
Delete several predicates that wrote to the current output stream,
since all their callers now use the versions that specify an explicit
output stream.

compiler/unique_modes.m:
compiler/unneeded_code.m:
compiler/write_module_interface_files.m:
Get these modules to take an explicitly specified stream to which
to write progress messages when they are invoked from mercury_compile_*.m.
For predicates in these modules that can be invoked both directly
by mercury_compile_*.m *and* by other modules, the latter effectively
as a subcontractor, make them take a maybe(stream), with the intention
being that all the other modules that use the predicate as a subcontractor
would pass a "no". This avoids the need to pass progress streams
down to the internals of other passes, and also avoids overwhelming
the user invoking the compiler with unnecessary details.
As above, and also delete a progress message that shouldn't be needed
anymore.
Move a test of option value compatibility from
mercury_compile_middle_passes.m to handle_options.m, where it belongs.
compiler/float_regs.m:
Write a debug message to the debug stream.
compiler/pd_info.m:
Include the progress stream in the pd_info structure, because this is
the simplest way to ensure that all parts of the partial deduction pass
have access to it.
compiler/make.build.m:
compiler/make.program_target.m:
compiler/make.track_flags.m:
Make the minimal changes needed to conform to the changes above.
The rest can be done when the make package is converted to consistently
use explicit streams.
compiler/bytecode_gen.m:
compiler/structure_reuse.direct.m:
compiler/structure_reuse.versions.m:
compiler/structure_sharing.analysis.m:
Make the minimal changes needed to conform to the changes above.
The rest can be done when these modules start being maintained again.
compiler/Mercury.options:
Stop specifying --no-warn-implicit-stream-calls for mercury_compile_*.m,
since this diff makes that unnecessary.
Start specifying --no-warn-implicit-stream-calls for some modules that
are not currently being actively maintained, because the addition of
progress-reporting predicates that take explicitly specified streams
would otherwise cause the generation of such warnings for them.

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.

Use explicit streams and var_tables in pd_*.m.
compiler/pd_debug.m:
compiler/pd_util.m:
Change the interface of pd_debug_message and pd_debug_message_context
to look up the pd_debug flag internally, instead of requiring callers
to do that themselves. Change their operation to always output
to the module's debug stream.
Delete pd_debug_write, which was not used.
Delete pd_debug_do_io after effectively inlining it at all its call sites.
Use var_tables instead of varsets and/or vartypes where relevant.
compiler/deforest.m:
Conform to the changes above.
compiler/hlds_out_mode.m:
For two predicates that output debug information, provide versions
that return a string instead. Replace a varset argument with a
var_name_source in both predicates and both functions.
compiler/stm_expand.m:
Use explicit streams.
compiler/Mercury.options:
Don't disable warnings about implicit stream calls in the modules above.

Carve three modules out of make.m.
compiler/make.top_level.m:
compiler/make.track_flags.m:
compiler/make.make_info.m:
Carve these three modules out of make.m.
make.top_level.m contains the top level of the mmc --make algorithm.
make.track_flags.m contains code for keeping track of which options
were used to compile which modules.
make.make_info.m defines the make_info structure used by all the
submodules of make.m, as well as a few other utility types.
compiler/notes/compiler_design.html:
Document the new modules.
compiler/make.m:
Delete the code that has been moved to the new modules, leaving
make.m as purely a package.
Include make.build.m in the interface, so we can delete the forwarding
predicate we used to have here for use by mercury_compile_main.m.
compiler/Mercury.options:
Make make.top_level.m and make.track_flags inherit make.m's old
-no-warn-implicit-stream-calls option.
compiler/file_names.m:
Move a utility function about extensions here from make.m.
This also allows the removal of an undesirable module import of make.m
in write_deps_file.m.
compiler/make.build.m:
Move a type here from make.m, since it is needed to allow
mercury_compile_main.m call this module directly (i.e. not through
a forwarding predicate in make.m).

Conform to the changes above. This mostly means having each module make.X
actually import the modules it uses, instead of relying on make.m
importing them, and getting those imports via make.int0.
In a few cases, it means having each module make.X NOT import the modules
it does NOT use, since after the "package-ification" of make.m,
we now get warnings about these imports being unused.

Carve three new modules out of polymorphism.m.
The remaining code of polymorphism.m is still less cohesive than
it ought to be, and could probably benefit from further reorganization
and/or breakup, but this diff is definitely a step in the right direction.
compiler/polymorphism_info.m:
A new module carved out of polymorphism.m, that defines
- the poly_info type,
- the types used in the fields in the poly_info type,
- the basic operations on the poly_info type and its component types,
- some very basic utility predicates used by several of polymorphism*.m.
It also contains the infrastructure needed for debugging the polymorphism
pass. This consists mainly of the mutables accessed from trace goals
in that pass.
Replace the bool type of one of these mutables with a bespoke type.
Attach the mutables to the I/O state, to avoid the need to make code
using those mutables semipure or impure.
compiler/polymorphism_type_info.m:
A new module carved out of polymorphism.m, that defines operations
that create type_infos, or extract type_infos from other type_infos
or typeclass_infos.
Add two new preds, polymorphism_make_type_info_{var,vars}_raw.
Unlike their old non-raw equivalents, these allow their callers to supply
module_infos, pred_infos and proc_infos without having to first construct
a poly_info from them.
compiler/polymorphism_lambda.m:
A new module carved out of polymorphism.m that manipulates lambda goals.
compiler/polymorphism.m:
Delete the code moved to the new modules.
Make the definition order of predicates in match their declaration order.
compiler/check_hlds.m:
Add the new modules to the check_hlds package.
compiler/notes/compiler_design.html:
Document the new modules. Fix some out-of-date and/or repetitive
existing documentation.
compiler/Mercury.options:
Require polymorphism.m to have matching declaration and definition orders
for its predicates.

compiler/equiv_type_hlds.m:

Impose logical order on mode_info.m and mode_util.m.

Put the predicates in these modules into logical groups, and ensure

Delete the unused predicates select_output_vars, select_output_things,

Specify output streams in some places.
Besides this main purpose, this diff also replaces code that calls
io.write_string several times in a row with code that prints the
thing to be printed in one go with io.format. In a couple of places,
this has caught (and fixed) bugs where we wanted to put `' quotes
around a filename, but printed only one of the two quotes.
compiler/file_util.m:
Provide alternatives to the existing maybe_report_stats,
maybe_write_string and maybe_flush_output predicates that explicitly
specify the output stream.
Rename report_error_to_stream as report_error, to allow
--warn-implicit-stream-calls to report calls to the existing report_error
predicate, which does not take an explicit output stream.
Add a module_name argument to the output_to_file_stream predicate,
to allow its code to figure out where to print both progress and
error messages.
compiler/module_cmds.m:
Add a module_name argument to the predicates that update interface,
to allow their code to figure out where to print both progress and
error messages.
For now, leave the predicates that issue commands that are not
clearly linked to a single module using implicit streams.
compiler/pd_debug.m:
compiler/analysis.file.m:
Specify output streams in some places.
In other places, doing so would require redoing the whole debug
infrastructure, since the current one is based on higher order predicates
that always write to the non-explicitly-specified *current* output stream.
compiler/passes_aux.m:
Provide predicates that get progress, debug and error streams
given a module_info, by extracting the globals and the module name
from the module_info, and then calling the predicates in globals.m
to get those streams. Doing this sequence of actions here factors out

Write to explicitly named streams in many modules.
Right now, most parts of the compiler write to the "current output stream".
This was a pragmatic choice at the time, but has not aged well. The problem
is that the answer to the question "where is the current output stream going?"
is not obvious in *all* places in the compiler (although it is obvious in
most). When using such implicit streams, finding where the output is going
to in a given predicate requires inspecting not just the ancestors of that
predicate, but also all their older siblings (since any of them could have
changed the current stream), *including* their entire call trees. This is
usually an infeasible task. By constrast, if we explicitly pass streams
to all output operations, we need only follow the places where the variable
representing that stream is bound, which the mode system makes easy.
This diff switches large parts of the compiler over to doing output only
to explicitly passed streams, never to the implicit "current output stream".
The parts it switches over are the parts that rely to a significant degree
on the innermost change, which is to the "output" typeclass in
parse_tree_out_info.m. This is the part that has to be switched over to
explicit streams first, because (a) many modules such as mercury_to_mercury.m
rely on the output typeclass, and (b) most other modules that do output
call predicates in these modules. Starting anywhere else would be like
building a skyscraper starting at the top.
This typeclass, output(U), has two instances: output(io), and output(string),
so you could output either to the current output stream, or to a string.
To allow the specification of the destination stream in the first case,
this diff changes the typeclass to output(S, U) with a functional dependency
from U to S, with the two instances being output(io.text_output_stream, io)
and output(unit, string). (The unit arg is ignored in the second case.)
There is a complication with the output typeclass method, add_list, that
outputs a list of items. The complication is that each item is output
by a predicate supplied by the caller, but the separator between the items
(usually a comma) is output by add_list itself. We don't want to give
callers of this method the opportunity to screw up by specifying (possibly
implicitly) two different output streams for these two purposes, so we want
(a) the caller to tell add_list where to put the separators, and then
(b) for add_list, not its caller, tell the user-supplied predicate what
stream to write to. This works only if the stream argument is just before
the di,uo pair of I/O state arguments, which differs from our usual practice
of passing the stream at or near the left edge of the argument list,
not near the right. The result of this complication is that two categories
of predicates that are and are not used to print items in a list differ
in where they put the stream in their argument lists. This makes it easy
to pass the stream in the wrong argument position if you call a predicate
without looking up its signature, and may require *changing* the argument
order when a predicate is used to print an item in a list for the first time.
A complete switch over to always passing the stream just before !IO
would fix this inconsistency, but is far to big a change to make all at once.
compiler/parse_tree_out_info.m:
Make the changes described above.
Add write_out_list, which is a variant of io.write_list specifically
designed to address the "complication" described above. It also has
the arguments in an order that is better suited for higher-order use.
Make the same change to argument order in the class method add_list
as well.
Almost all of the following changes consist of passing an extra stream
argument to output predicates. In some places, where I thought this would
aid readability, I replaced sequences of calls to output predicates
with a single io.format.
compiler/prog_out.m:
This module had many predicates that wrote things to the current output
stream. This diff adds versions of these predicates that take an
explicit stream argument.
If the originals are still needed after the changes to the other modules,
keep them, but add "_to_cur_stream" to the end of their names.
Otherwise, delete them. (Many of the changes below replace
write_xyz(..., !IO) with io.write_string(Stream, xyz_to_string(...), !IO),
especially when write_xyz did nothing except call xyz_to_string
and wrote out the result.)
compiler/c_util.m:
Add either an explicit stream argument to the argument list, or a
"_current_stream" suffix to the name, of every predicate defined
in this module that does output.
Add a new predicate to print out the block comment containing
input for mkinit. This factors out common code in the LLDS and MLDS
backends.
compiler/name_mangle.m:
Delete all predicates that used to write to the current output stream,
after replacing them if necessary with functions that return a string,
which the caller can print to wherever it wants. (The "if necessary"
part is there because some of the "replacement" functions already
existed.)
When converting a proc_label to a string, *always* require the caller
to say whether the label prefix should be added to the string,
instead of silently assuming "yes, add it", as calls to one of the old,
now deleted predicates had it.
compiler/file_util.m:
Add output_to_file_stream, a version of output_to_file which
simply passes the output file stream it opens to the predicate
that is intended to define the contents of the newly created or
updated file. The existing output_to_file, which instead sets
and resets the current output stream around the equivalent
predicate call, is still needed e.g. by the MLDS backend,
but hopefully for not too long.

compiler/intermod.m:

belong in this diff because these modules call many of the output
predicates in the parse tree package.)
In hlds_out_util.m, delete some write_to_xyz(...) predicates that wrote
the result of xyz_to_string(...) to the current output stream.
Replace calls to the deleted predicates with calls to io.write_string
with the string being written being computed by xyz_to_string.
Add a predicate to hlds_out_util.m that outputs a comment containing
the current context, if it is valid. This factors out code that used
to be common to several of the other modules.
In a few places in hlds_out_module.m, the new code generates a
slighly different set of blank lines, but this should not be a problem.

Fix "this disjunct can't have solutions" warnings in multimode preds.
This fixes github issue #85. A complication is that the compiler itself has code, in make.util.m, in which a disjunct has no solutions in only one mode of a two mode function, but in this case, the code works (though its programming style is pretty bad), so to get this change to bootstrap, we also need a way to disable the "this disjunct can't have solutions" warning in a scope. compiler/simplify_goal_disj.m: When we generate a "this disjunct can't succeed" warning, do not insist on all modes generating that warning. We used to insist on that because in a multi-mode predicate, such warnings can be inappropriate for other modes. Instead, achieve the same objective of minimizing programmer confusion by adding a codicil explicitly mentioninging this possibility. Make the generation of this warning conditional on a simplify task that can be disabled by "disable_warnings" scope. compiler/prog_data.m: Add "no_solution_disjunct" as a warning kind that may be disabled. compiler/parse_goal.m: Parse the new kind of warning. compiler/prog_out.m: Output the new kind of warning.

Make pre-HLDS passes use file-kind-specific parse trees.
Replacing item blocks file-kind-specific kinds of section markers with
file-kind-specific parse trees has several benefits.
- It allows us to encode the structural invariants of each kind of file
we read in within the type of its representation. This makes the detection
of any accidental violations of those invariants trivial.
- Since each file-kind-specific parse tree has separate lists for separate
kinds of items, code that wants to operate on one or a few kinds of items
can just operate on those kinds of items, without having to traverse
item blocks containing many other kinds of items as well. The most
important consequence of this is not the improved efficiency, though
that is nice, but the increased clarity of the code.
- The new design is much more flexible. For example, it should be possible
to record that e.g. an interface file we read in as a indirect dependency
(i.e. a file we read not because its module was imported by the module
we are compiling, but because its module was imported by *another* imported
module) should be used *only* for the purpose it was read in for. This should
avoid situations where deleting an import of A from a module, because it
is not needed anymore, leads the compiler to generate an error message
about a missing import of module B. This can happen if (a) module B
always *should* have been imported, since it is used, but (b) module A's
import of module B lead to module B's interface being available *without*
an import of B.
Specifically, this flexibility should enable us to establish each module's
.int file as the single source of truth about how values of each type
defined in that module should be represented. When compiling each source
file, this approach requires the compiler to read in that module's .int file
but using only the type_repn items from that .int file, and nothing else.
- By recording a single parse tree for each file we have read, instead of
a varying number of item blocks, it should be significantly easier to
derive the contents of .d files directly from the records of those
parse trees, *without* having to maintain a separate set of fields
in the module_and_imports structure for that purpose. We could also
trivially avoid any possibility of inconsistencies between these two
different sources of truth. (We currently fill in the fields used to
drive the generation of .d files using two different pieces of code,
one used for --generate-dependencies and one used for all other invocations,
and these two *definitely* generate inconsistent results, as the significant
differences in .d files between (a) just after an invocation of
--generate-dependencies and (b) just after any other compiler invocation
can witness.)
This change is big and therefore hard to review. Therefore in many files,
this change adds "XXX CLEANUP" comments to draw attention to places that
have issues that should be fixed, but whose fixes should come later, in
separate diffs.
compiler/module_imports.m:
The compiler uses the module_and_imports structure defined here
to go from a raw compilation unit (essentially a module to be compiled)
to an augmented compilation unit (a raw compilation unit together
with all the interface and optimization files its compilation needs).
We used to store the contents of both the source file and of
the interface and optimization files in the module_and_imports structure
as item blocks. This diff replaces all those item blocks with
file-kind-specific parse trees, for the reasons mentioned above.
Separate out the .int0 files of ancestors modules from the .intN
files for N>0 of directly imported modules. (Their item blocks
used to be stored in the same list.)
Maintain a database of the source, interface and optimization files
we have read in so far. We use it to avoid reading in interface files
if we have already read in a file for the same module that contains
strictly more information (either an interface file with a smaller
number as a suffix, or the source file itself).
Shorten some field names.
compiler/prog_item.m:
Define data structures for storing information about include_module,
import_module and use_module declarations, both in a form that allows
the representation of possibly erroneous code in actual source files,
and in checked-and-cleaned-up form which is guaranteed to be free
of the relevant kinds of errors. Add a block comment at the start
of the module about the need for this distinction.
Define parse_tree_module_src, a data structure for representing
the source code of a single module. This is different from the existing
parse_tree_src type, which represents the contents of a single source file
but which may contain *more* than one module, and also different from
a raw_compilation_unit, which is based on item blocks and is thus
unable to express to invariants such as "no clauses in the interface".
Modify the existing parse_tree_intN types to express the distinction
mentioned just above, and to unify them "culturally", i.e. if they
store the same information, make them store it using the same types.
Fix a mistake by allowing promises to appear in .opt files.
I originally ruled them out because the code that generates .opt files
does not have any code to write out promises, but some of the predicates
whose clauses it writes out have goal_type_promise, which means that
they originated as promises, and get written out as promises.
Split the existing pragma item kind into three item kinds, which have
different invariants applying to them.
- The decl (short for declarative) pragmas give the compiler some
information, such as that a predicate is obsolete or that we
want to type specialize some predicate or function, that is in effect
part of the module's interface. Decl pragmas may appear in module
interfaces, and the compiler may put them into interface files;
neither statement is true of the other two kinds of pragmas.
- The impl (short for implementation) pragmas are named so
precisely because they may appear only in implementation sections.
They give the compiler information that is private to that module.
Examples include foreign_decls, foreign_codes, foreign_procs,
and promises of clause equivalence, and requests for inlining,
tabling etc. These will never be put into interface files,
though some of them can affect the compilation of other modules
by being included in .opt files.
- The gen (short for generated) pragmas can never (legally) appear
in source files at all. They record the results of compiler
analyses e.g. about which arguments of a predicate are unused,
or what exceptions a function can throw, and accordingly they
should only ever occur in compiler-generated interface files.
Use the new type differences between the three kinds of pragmas
to encode the above invariants about which kinds of pragmas can appear
where into the various kinds of parse trees.
Make the augmented compilation unit, which is computed from
the final module_and_imports structure, likewise switch from
storing item blocks to storing the whole parse trees of the
files that went into its construction. With each such parse tree,
record *why* we read it, since this controls what permissions
the source module being compiled has for access to the entities
in the parse tree.
Simplify the contains_foreign_code type, since one of three
function symbols was equivalent to one possible use of another
function symbol.
Provide a way to record which method of which class a compiler-generated
predicate is for. (See hlds_pred.m below.)
Move the code of almost all utility operations to item_util.m
(which is imported by many fewer modules than prog_item.m),
keeping just the most "popular" ones.
compiler/item_util.m:
Move most of the previously-existing utility operations here from
prog_item.m, most in a pretty heavily modified form.
Add a whole bunch of other utility operations that are needed
in more than one other module.
compiler/convert_parse_tree.m:
Provide predicates to convert from raw compilation units to
parse_tree_module_srcs, and vice versa (though the reverse
shouldn't be needed much longer).
Update the conversion operations between the general parse_tree_int
and the specific parse_tree_intN forms for the changes in prog_item.m
mentioned above. In doing so, use a consistent approach, based on
new operations in item_util.m, to detect errors such as duplicate
include_module and import/use_module declarations in all kinds
of parse trees.
Enforce the invariants that the types of parse trees of various kinds
can now express in types, generating error messages for their violations.
Delete some utility operations that have been moved to item_util.m
because now they are also needed by other modules.
compiler/grab_modules.m:
Delete code that did tests on raw compilation units that are now done
when that raw compilation unit is converted to a parse_tree_module_src.
Use the results of the checks done during that conversion to decide
which modules are imported/used and in which module section.
Record a single reason for why we reading in each interface and
optimization file. The code of make_hlds_separate_items.m will use
this reason to set up the appropriate permissions for each item
in those files.
Use separate code for handling different kinds of interface and
optimization files. Using generic traversal code was acceptable economy
when we used the same data structure for every kind of interface file,
but now that we *can* express different invariants for different kinds
of interface and optimization file, we want to execute not just different
code for each kind of file, but the data structures we want to work on
are also of different types. Using file-kind-specific code is a bit
longer, but it is significantly simpler and more robust, and it is
*much* easier to read and understand.
Delete the code that separates the parts of the implementation section
that are exported to submodules, and the part that isn't, since that task
is now done in make_hlds_separate_items.m.
Pass a database of the files we have read through the relevant predicates.
Give some predicates more meaningful names.
compiler/notes/interface_files.html:
Note a problem with the current operation of grab_modules.
compiler/get_dependencies.m:
Add operations to gather implicit references to builtin modules
(which have to be made available even without an explicit import_module
or use_module declaration) in all kinds of parse trees. These have
more code overall, but will be at runtime, since we need only look at
the item kinds that may *have* such implicit references.
Add a mechanism to record the result of these gathering operations
in import_and_or_use_maps.
Give some types, function symbols, predicates and variables
more meaningful names.
compiler/make_hlds_separate_items.m:
When we stored the contents of the source module and the
interface and optimization files we read in to augment it
in the module_and_imports structure as a bunch of item blocks,
the job of this module was to separate out the different kinds of items
in the item blocks, returning a single list of each kind of item,
with each such item being packaged up with its status (which encodes
a set of permissions saying what the source module is allowed
to do with it).
Now that the module_and_imports structure stores this info in
file-kind-specific parse trees, all of which have separate lists
for each kind of item and none of which contain item blocks,
the job of this module has changed. Now its job is to convert
the reason why each file was read in into the (one or more) statuses
that apply to the different kinds of items stored in it, wrap up
each item with its status, and return the resulting overall list
of status/item pairs for each kind of item.
compiler/read_modules.m:
Add predicates that, when reading an interface file, return its contents
in the tightest possible file-kind-specific parse tree.
Refine the database of files we have read to allow us to store
more file-kind-specific parse trees.
Don't require that files in the database have associated timestamps,
since in some cases, we read files we can put into the database
*without* getting their timestamps.
Allow the database to record that an attempt to read a file failed.
compiler/split_parse_tree_src.m:
Rearchitect how this module separates out nested submodules from within
the main module in a file.
Another of the jobs of this module is to generate error messages for
when module A includes module B twice, whether via nesting or via
include_module declarations, with one special exception for the case
where A's interface contains nested submodule A.B's interface,
and A's implementation contains nested submodule A.B's implementation.
The problem ironically was that while it reported duplicate include_module
declarations as errors, split_parse_tree_src.m also *generated*
duplicate include_module declarations. Since it replaced each nested
submodule occurrence with an include_module declaration, in the scenario
above, it generated two include_module declarations for A.B. Even worse,
the interface incarnation of submodule A.B could contain
(the interface of) its own nested submodule A.B.C, while its
implementation incarnation could contain (the implementation section of)
A.B.C. Each occurrence of A.B.C would be its only occurrence in the
including part of its parent A.B, which means local tests for duplicates
do not work. (I found this out the hard way.)
The solution we now adopt adds include_module declarations to the
parents of any submodule only once the parse tree of the entire
file has been processed, since only then do we know all the
includer/included relationships among nested modules. Until then,
we just record such relationships in a database as we discover them,
reporting duplicates when needed (e.g. when A includes B twice
*in the same section*), but not reporting duplicates when not needed
(e.g. when A.B includes A.B.C in *different* sections).
compiler/prog_data.m:
Add a new type, pf_sym_name_and_arity, that exactly specifies
a predicate or function. It is a clone of the existing simple_call_id
type, but its name does NOT imply that the predicate or function
is being called.
Add XXXs that call for some other improvements in type names.
compiler/prog_data_foreign.m:
Give a type, and the operations on that type, a more specific name.
compiler/error_util.m:
Add an id field to all error_specs, which by convention should be
filled in with $pred. Print out the value in this field if the compiler
is invoked with the developer-only option --print-error-spec-id.
This allows a person debugging the compiler find out where in the code
an undesired error message is coming from significantly easier
than was previously possible.
Most of the modules that have changes only "to conform to the changes
above" will be for this change. In many cases, the updated code
will also simplify the creation of the affected error_specs.
Fix a bug that looked for a phase in only one kind of error_spec.
Add some utility operations needed by other parts of this change.
Delete a previously internal function that has been moved to
mdbcomp/prim_data.m to make it accessible in other modules as well.
compiler/Mercury.options:
Ask the compiler to warn about dead predicates in every module
touched by this change (at least in one its earlier versions).
compiler/add_foreign_enum.m:
Replace a check for an inappropriately placed foreign_enum declaration
with a sanity check, since with this diff, the error should be caught
earlier.
compiler/add_mutable_aux_preds.m:
Delete a check for an inappropriately placed mutable declaration,
since with this diff, the error should be caught earlier.
compiler/add_pragma.m:
Instead of adding pass2 and pass3 pragmas, add decl and impl and
generated pragmas.
Delete the tests for generated pragma occurring anywhere except
.opt files, since those tests are now done earlier.
Shorten some too-long predicate names.
compiler/comp_unit_interface.m:
Operate on as specific kinds of parse trees as the interface of this
module will allow. (We could operate on more specific parse trees
if we changed the interface, but that is future work).
Use the same predicates for handling duplicate include_module,
import_module and use_module declarations as everywhere else.
Delete the code of an experiment that shouldn't be needed anymore.
compiler/equiv_type.m:
Replace code that operated on item blocks with code that operates
on various kinds of parse trees.
Move a giant block of comments to the front, where it belongs.
compiler/hlds_module.m:
Add a field to the module_info that lets us avoid generating
misleading error messages above missing definitions of predicates
or functions when those definitions were present but were not
added to the HLDS because they had errors.
Give a field and its access predicates a more specific name.
Mark a spot where an existing type cannot express everything
it is supposed to.
compiler/hlds_pred.m:
For predicates which the compiler creates to represent a class method
(the virtual function, in OOP terms), record not just this fact,
but the id of the class and of the method. Using this extra info
in progress messages (with mmc -V) prevents the compiler from printing e.g.
% Checking typeclass constraints on class method
% Checking typeclass constraints on class method
% Checking typeclass constraints on class method
when checking three such predicates.
compiler/make.m:
Provide a slot in the make_info structure to allow the database
of the files we have read in to be passed around.
compiler/make_hlds_error.m:
Delete predicates that are needed in just one other module,
and have therefore been moved there.
compiler/make_hlds_passes.m:
Add decl, impl and generated pragma separately, instead of adding
pass2 and pass3 pragmas separately.
Do not generate error messages for clauses, initialises or finalises
in module interfaces, since with this diff, such errors should be
caught earlier.
compiler/mercury_compile_main.m:
compiler/recompilation.check.m:
Explicitly pass around the expanded database of parse trees
of files that have been read in.
compiler/module_qual.collect_mq_info.m:
compiler/module_qual.m:
compiler/module_qual.qualify_items.m:
Collect module qualification information, and do module qualification
respectively on parse trees of various kinds, not item blocks.
Take information about what the module may do with the contents
of each interface or optimization file from the record of why
we read that file, not from the section markers in item blocks.
Break up some too-large predicates by carving smaller ones out of them.
compiler/options.m:
Add an option to control whether errors and/or warnings detecting
when deciding what should go into a .intN file be printed,
thus (potentially) preventing the creation of that file.
Add commented-out documentation for a previously totally undocumented
option.
doc/user_guide.texi:
Document the new option.
NEWS:
Announce the new option.
Mention that we now generate warnings for unused import_module and
use_module declarations in the interface even if the module has
submodules.
compiler/write_module_interface_files.m:
Let the new option control whether we filter out any messages generated
when deciding what should go into a .intN file.
compiler/parse_item.m:
Delete actually_read_module_opt, since it is no longer needed;
its callers now call actually_read_module_{plain,trans}_opt instead.
Delete unneeded arguments from some predicates.
compiler/parse_module.m:
Delete some long unused predicates.
compiler/parse_pragma.m:
When parsing pragmas, wrap them up in the new decl, impl or generated
pragma kinds.
compiler/parse_tree_out.m:
Add predicates to write out each of the file-kind-specific parse trees.
compiler/parse_tree_out_pragma.m:
Add predicates to write out decl, impl and generated pragmas.
compiler/polymorphism.m:
Add a conditionally-enabled progress message, which can be useful
in tracking down problems.
compiler/prog_item_stats.m:
Conform NOT to the changes above beyond what is needed to let this module
compile. Let that work be done the next time the functionality of
this module is needed, by which time the affected data structures
maybe have changed further.
compiler/typecheck.m:
Fix a performance problem. With intermodule optimization, we read in
.opt files, some of which (e.g. list.opt and int.opt) contain promises.
These promises are read in as predicates with goal_type_promise,
but they do not have declarations of the types of their arguments
(since promises do not have declarations as such). Those argument types
therefore have to be inferred. That inference replaces the original
"I don't know" argument types with their actual types.
The performance problem is that when we change the recorded argument types
of a predicate, we require another loop over all the predicates in the
module, so that any calls to this predicate can be checked against
the updated types. This is as it should be for callable predicates,
but promises are not callable. So if all the *only* predicates whose
recorded argument types change during the first iteration to fixpoint
are promises, then a second iteration is not needed, yet we used to do it.
The fix is to replace the "Have the recorded types of this predicate
changed?" boolean flag with a bespoke enum that says "Did the checking
of this predicate discover a need for another iteration", and not
setting it when processing predicates whose type is goal_type_promise.
compiler/typecheck_errors.m:
Do not generate an error message for a predicate missing its clauses
is the clauses existed but were not added to the HLDS because they were
in the interface section.
When reporting on ambiguities (when a call can match more than one
predicate or function), sort the possible matches before reporting
them.

scripts/compare_s1s2_lib:
A new script that helped debug this diff, and may help debug
similar diffs the future. It can compare (a) .int* files, (b) .*opt
files, (c) .mh/.mih files or (d) .c files between the stage 1 and
stage 2 library directories. The reason for the restriction
to the library directory is that any problems affecting the
generation of any of these kinds of files are likely to manifest
themselves in the library directory, and if they do, the bootcheck
won't go on to compile any of the other stage 2 directories.
tests/debugger/breakpoints.a.m:
tests/debugger/breakpoints.b.m:
Move import_module declarations to the implementation section
when they are not used in the interface. Until now, the compiler
has ignored this, but this diff causes the compiler to generate
a warning for such misplaced import_module declarations even modules
that have submodules. The testing of such warnings is not the point
of the breakpoints test.

generated during an invocation of mmc --make-interface, add the
new option that *allows* that invocation to generate error messages.
tests/invalid/ambiguous_overloading_error.err_exp:

the possible matches are sorted.

Fix programming style.

Expect an error message for a foreign_export_enum item in the interface,
where it should not be.
tests/invalid/errors.err_exp:
Expect the expanded wording of a warning message.
tests/invalid/foreign_enum_invalid.err_exp:
Expect a different wording for an error message. It is more "standard"
but slightly less informative.
tests/invalid_submodules/children2.m:
Move a badly placed import_module declaration, to avoid having
the message the compiler now generates for it from affecting the test.
tests/submodules/parent2.m:
Move a badly placed import_module declaration, to avoid having
the message the compiler now generates for it from affecting the test.
Update programming style.

Decide simple representations using checked type definitions.
compiler/check_parse_tree_type_defns.m:
Change the definition of a checked type to distinguish direct_dummy
and enum types on the one hand, which may have foreign enum definitions,
from other du types, which may not.
Change the definition of a checked type to record the names of the
function symbols in direct_dummy and enum types, since type representation
items need this information, we have it, and requiring decide_type_repn.m
to compute it again from scratch is wasteful.
Do not explicitly record the number of function symbols in direct_dummy
% and enum types, and the number bits needed to represent values of
such types. We now store the list of function symbols in such types,
and this information is trivially computable from that.
Check foreign enum definitions for correctness. At the moment,
this sort-of duplicates related functionality in add_foreign_enum.m,
but the intention is that eventually, these checks will be done only here,
with the sort-of duplicated code in add_foreign_enum.m being deleted there.
compiler/prog_item.m:
Change the data structures we use to record type representation information
in items to encode all the invariants that the updated checked type
definition map encodes. This should allow code that reads such items
from interface files to avoid having to check for violations of those
invariants.
Document the relationship between checked type definitions and
type representation items, including why neither can subsume the other.
compiler/decide_type_repn.m:
Rewrite this module almost completely. The old version gathered up
all the type and enum definitions for each type constructor, and then
did a limited, purpose-specific job of checking their consistency,
before using the information in them to decide on the representations
of simple types. The new version takes a checked type definition map
as input, and so its task is limited to deciding type representations.
The switch has two main benefits.
- The consistency checks we now do in check_parse_tree_type_defns.m
can replace not just the consistency checks we used to do in
decide_type_repn.m, but in the future, it can also replace
the consistency checks we now do in add_type.m and add_foreign_enum.m.
Having a *consistent* set of consistency checks is a good idea,
even though it is a bit too meta :-)
- The consistency checks in check_parse_tree_type_defns.m
are significantly more thorough than both the ones in the version
of decide_type_repn.m, and the current version distributed through
add_type.m and add_foreign_enum.m.
The changes in check_parse_tree_type_defns.m and prog_item.m to bring
the two representations as close together as possible should significantly
simplify the code we will need to add to decide_type_repn.m to decide
the representations of complex types.
compiler/comp_unit_interface.m:
Pass the checked type definition map to decide_type_repn.m.
compiler/parse_type_repn.m:
Parse the updated type representations.
compiler/parse_tree_out.m:
Output the updated type representations.
compiler/du_type_layout.m:
compiler/prog_data.m:
Move a predicate from du_type_layout.m to prog_data.m (split into
two predicates), since decide_type_repn.m now wants access to its
functionality as well.
compiler/prog_type.m:
Export a utility predicate.
compiler/add_foreign_enum.m:
Export some functionality to check_parse_tree_type_defns.m.
That functionality should in fact be moved to check_parse_tree_type_defns,
but that would make this diff harder to review, so that will be done later
in a separate commit.
compiler/equiv_type.m:
compiler/module_qual.qualify_items.m:
Conform to the changes above.
compiler/Mercury.options:
Specify --warn-dead-preds for the modules touched by this change.
Since several of them had large parts replaced by new code, this was
needed to catch left-over parts of their old and now obsolete contents.

Check the type definitions in a module for consistency ...
... when generating interface files.
compiler/check_parse_tree_type_defns.m:
A new module for doing the checking.
compiler/parse_tree.m:
Add the new module.
compiler/comp_unit_interface.m:
When computing what should go into a .intN file, use the new module
to check for inconsistencies in the source code of the module.
Making the above possible requires retaining some information
(such as contexts in foreign enum definitions, and the presence
of definitions, as opposed to declarations, for some types)
for longer than was needed until now.
Give some predicates more descriptive names.
Move the record_foreign_enum_spec predicate near where it is used.
compiler/write_module_interface_files.m:
If comp_unit_interface.m reports any errors when generating the
would-be contents of an interface file, do NOT create that
interface file.
The errors comp_unit_interface.m and check_parse_tree_type_defns.m
now generate are the kinds of inconsistencies whose resolution requires
everything depending on this module to be recompiled anyway,
so stopping the compilation process *without* producing
the would-be-erroneous interface file should be a net win
almost all the time.
compiler/prog_item.m:
Factor out some commonalities in data structures.
When converting the generic parse_tree_int we get from reading
in a .intN file to the parse tree type specific to that N,
check the definitions we read in for consistency.
As in comp_unit_interface, making the above possible requires
retaining some information for longer than was needed until now.
Never output two or more declarations of the same type_ctor
in the same section of an interface file, since the code
*reading* interface files now reports such redundancies
(but see the change to options.m).
compiler/options.m:
Disable the printing of error messages for problems found in
interface files, since the new code in check_parse_tree_type_defns.m
now finds problems in interface files generated by currently
installed compilers. Specifically, many contain duplicate
declarations for Mercury types. One declaration is written
by the programmer, the other is the type's actual definition
turned into the redundant declaration by the compiler.
compiler/parse_pragma.m:
When parsing foreign enum pragmas, implicitly qualify the
name of the type constructor they are for with the current module name.
This is semantically sound, since foreign_enum pragmas *must* be
for a type constructor defined in the same module. It is desirable
because type_ctors in type definitions are module qualified.
The code of check_parse_tree_type_defns.m needs to process
the type definitions and foreign enums for a type_ctor at the
same time, and doing so would be more needlessly complicated
if the type ctor keys in the "type_ctor to type definitions"
and "type_ctor to foreign enums" maps were incompatible due to
the difference in qualification.
The type_ctor in a foreign enum definition may still be manually
module qualified by programmers; it just happens that any qualification
other than the default is a semantic error.
compiler/module_qual.qual_errors.m:
When printing error messages about undefined type_ctors in
foreign enum definitions, do not print this implicitly
added qualification, since it adds only clutter.
compiler/error_util.m:
Provide a mechanism for printing type_ctors directly,
i.e. without converting them to a sym_name/arity pair.
Put a qual_ prefix in front of top_ctor_of_type, since it
always prints module qualification. (This is to remind people
who may use this component about that qualification.)
Factor out some common code.
compiler/det_analysis.m:
Conform to the change in error_util.m.
compiler/parse_module.m:
Fix too-long lines.
compiler/Mercury.options:
Require some of the modules above to have no dead predicates.
library/erlang_rtti_implementation.m:
library/io.m:
Delete declarations of types that are unneeded because the types
also have definitions.
tests/typeclasses/unqualified_method2.m:
Move an import out of the interface, since we now print the warning
generated for its improper location.
