now that Erlang is no longer a target language.
compiler/parse_type_repn.m:
Accept both the updated version of the item_type_repn_info and the
immediately previous version, since the installed compiler will
initially generate that previous version. However, stop accepting
an even older version that we stopped generating several months ago.

When the compiler finds a reference to Erlang as a foreign language,
add a message about support for Erlang being discontinued to the error

Make the code parsing foreign_decls handle the term containing
the foreign language the same way as the codes parsing foreign
codes, procs, types and enums.
Add a mechanism to help parse_mutable.m to do the same.

Simplify implications of debugging.

Having debugging enabled affects several classes of options the same way.
Record this effect in one flag per class, not on every option
separately.

Replace given_trace_level_is_none, which used to return a bool, with
is_exec_trace_enabled_at_given_trace_level, which now returns either
exec_trace_is_not_enabled or exec_trace_is_enabled. This should
allow peopl to read code calling the function without having to
process double negatives in their head.

Unify getopt.m and getopt_io.m ...
... using an approach proposed by Peter, with an extra twist from Julien.
Instead of having two modules, getopt.m and getopt_io.m, with the former
defining predicates that do not take an I/O state pair, and the latter
defining predicates that do take an I/O state pair, put both kinds of
predicates into a single module. The versions with an I/O state pair
have an "_io" suffix added to their names for disambiguation.
Both versions are a veneer on top of a common infrastructure,
which relies on a simple type class to implement the operation
"give the contents of the file with this name". The predicate versions
with I/O state pairs have a normal implementation of this typeclass,
while the predicate versions that do not have I/O state pairs
have an implementation that always returns an error indication.
The above change just about doubles the number of exported predicates.
We already had two versions of most exported predicates that differed
in whether we returned errors in the form of a string, or in the form
of a structured representation, with names of the latter having
an "_se" suffix. Since we agreed that the structured representation
is the form we want to encourage, this diff deletes the string versions,
and deletes the "_se" suffix from the predicate names that used to have them.
(It still remains at the end of the name of a type.) This "undoubling"
should offset the effect of the doubling in the previous paragraph.
Eventually, we want to have just one module, getopt.m, containing
the updated code described above, but for now, we put the same code
into both getopt_io.m and getopt.m to prevent too big a shock to
people with existing code that uses getopt_io.m.

how these changes could have caused the error, and thus what the
probable fix is.

Avoid -O<n> resetting previously set options.
This implements Mantis feature request #495. NEWS: Announce the change. compiler/optimization_options.m: A new module for managing optimization options. It defines a separate bespoke type for every boolean optimization option to make it harder to confuse them. It defines a tuple type (opt_tuple) for accessing optimization options quickly. It implements the turning on (but NOT turning off) of optimizations when a given optimization level is selected. tools/make_optimization_options_middle: tools/make_optimization_options_db: The script that generates the meat of optimization_options.m, and the database of option names, kinds and initial values that it uses as its input. The script also generates some code for the special_handler predicate in compiler/options.m. tools/make_optimization_options_start: tools/make_optimization_options_end: The handwritten initial and final parts of optimization_options.m. tools/make_optimization_options: The script that pulls these parts together to form optimization_options.m. compiler/options.m: Make every optimization option a special option, to be handled by the special_handler predicate. That handling consists of simply adding a representation of the option to the end of a cord of optimization options, to be processed later by optimization_options.m. That processing will record the values of these options in the opt_tuple, which is where every other part of the compiler should get them from. Change the interface of special_handler to make the above possible. Add an "optopt_" (optimization option) prefix to the name of every optimization option, to make them inaccessible to the rest of the compiler under their old name, and thus help enforce the switch to using the opt_tuple. Any access to these options to look up their values would fail anyway, since the option data would no longer be e.g. bool(yes), but bool_special, but the name change makes this failure happen at compile time, not runtime. Reclassify a few options to make the above make sense. Some options (unneeded_code_debug, unneeded_code_debug_pred_name, and common_struct_preds) were classified as oc_opt even though they control only the *debugging* of optimizations, while some options (c_optimize and inline_alloc) were not classified as oc_opt even though we do set them automatically at some optimization levels. Delete the opt_level_number option, since it was not used anywhere. Delete the code for handling -ON and --opt-space, since that is now done in optimization_options.m. Add some XXXs. compiler/handle_options.m: Switch to using getopt_io.process_options_userdata_se, as required by the new interface of the special_handler in options.m. In the absence of errors, invoke optimization_options.m to initialize the opt_tuple. Then update the opt_tuple incrementally when processing option implications that affect optimization options. compiler/globals.m: Put the opt_tuple into a new field of the globals structure. compiler/accumulator.m: compiler/add_pragma_type_spec.m: compiler/add_trail_ops.m: compiler/code_info.m: compiler/code_loc_dep.m: compiler/compile_target_code.m: compiler/const_struct.m: compiler/deforest.m: compiler/dep_par_conj.m: compiler/disj_gen.m: compiler/erl_code_gen.m: compiler/format_call.m: compiler/global_data.m: compiler/grab_modules.m: compiler/higher_order.m: compiler/hlds_pred.m: compiler/inlining.m: compiler/intermod.m: compiler/ite_gen.m: compiler/jumpopt.m: compiler/libs.m: compiler/llds_out_code_addr.m: compiler/llds_out_data.m: compiler/llds_out_file.m: compiler/llds_out_instr.m: compiler/llds_out_util.m: compiler/matching.m: compiler/mercury_compile_front_end.m: compiler/mercury_compile_llds_back_end.m: compiler/mercury_compile_main.m: compiler/mercury_compile_middle_passes.m: compiler/mercury_compile_mlds_back_end.m: compiler/ml_disj_gen.m: compiler/ml_gen_info.m: compiler/ml_lookup_switch.m: compiler/ml_optimize.m: compiler/ml_proc_gen.m: compiler/ml_simplify_switch.m: compiler/ml_switch_gen.m: compiler/ml_unify_gen_construct.m: compiler/optimize.m: compiler/pd_util.m: compiler/peephole.m: compiler/polymorphism.m: compiler/proc_gen.m: compiler/simplify_goal_call.m: compiler/simplify_goal_scope.m: compiler/simplify_info.m: compiler/simplify_proc.m: compiler/simplify_tasks.m: compiler/stack_layout.m: compiler/stack_opt.m: compiler/switch_gen.m: compiler/switch_util.m: compiler/tag_switch.m: compiler/tupling.m: compiler/unify_gen_construct.m: compiler/unneeded_code.m: compiler/unused_args.m: Conform to the changes above, mostly by looking up optimization options in the opt_tuple. In some places, replace bools containing optimization options with the bespoke type of that specific optimization option. library/getopt_template: Fix a bug that screwed up an error message. The bug happened when processing a --file option. If one of the options in the file was a special option whose special handler failed, the code handling that failing option returned both an error indication, and the rest of the argument list read in from the file. The code handling the --file option then *ignored* the error indication from the failed special option, and returned an error message of its own complaining about the unconsumed remaining arguments in the file, believing them to be non-option arguments, even though these arguments were never looked it to see if they were options. The fix is for the code handling --flag options to check whether the code processing the file contents found any errors, and if so, return that error *without* looking at the list of remaining arguments. In an unrelated change, factor out a duplicate call. |

Partition extensions into ".m" and "all others".
This is a first step towards a much finer grained partition.
compiler/file_names.m:
Split the ext type into ext_src and ext_other, as mentioned above.
Add the first predicate for checking whether a string falls into
a given category of extensions.
Add an XXX proposing a better solution for an old problem that does not
actually arise in practice.
compiler/compile_target_code.m:
Split the two-moded predicate maybe_pic_object_file_extension into
two separate one-mode predicates, one for each old mode. The
implementations of the two modes were already separate, because
the two modes already did different jobs: while one went from PIC
to an "extension", the other went from an "extension string" to PIC.
Until now, "extension" and "extension string" were equivalent;
after this diff, they aren't anymore.
Delete an unused argument.
compiler/make.util.m:
Split the two-moded predicate target_extension into
two separate one-mode predicates, one for each old mode,
for the same reason as maybe_pic_object_file_extension above:
the fact that "extension" and "extension string" are now distinct.
compiler/options_file.m:
Move debug infrastructure here from mercury_compile_main.m, to help
debug possible problems with options files. (I had such a problem
while writing this diff.)
Improve how progress messages are printed.
compiler/options.m:
Make an error message more useful.

Make filename extensions a separate type, ...
... to allow later changes to its definition.
compiler/file_names.m:
We used to represent filename extensions simply as strings. This meant
all calls to the predicates in file_names.m that convert module names
to file names with various suffixes had to go through a complicated
sequence of tests that effectively partition the extensions into
several classes, with all extensions in a class being treated the same
but different classes being treated differently. And since this general
translation process is quite convoluted (which is not helped by it
being spread across several predicates), it is very hard to construct
a correctness argument for it.
It would be better to represent the different classes of extensions
explicitly, in a du type, with each function symbol of that type
representing all the extensions in the corresponding class (in the sense
of the paragraph above). However, getting there in one diff would make
that diff far too hard to test and to review. So this first diff
starts by simply making extension a notag type.
The above is the first step in implementing one old XXX. This diff
fully implements another old XXX, which is to make the argument order
of several predicates friendly to higher order code.
Add infrastructure for profiling how often this code makes directories.
Delete an unused type.
Add comments outlining proposed future improvements.

Consistently use "Ext" for the abstract representation of extensions

In a few places, add "XXX EXT" where the code manipulates extensions
as strings in a way that potentially inferferes with the partition
of extensions into classes.
In a few places, rename predicates to avoid ambiguities. factor out
common code, delete unneeded arguments, replace bools with bespoke types,
and make similar minor improvements.
In a few places, remove rafe-isms, such as the use ^elem.

Remove the hl grade component.
As we discussed, it has fallen into disuse. Its main purpose was to
pave the way for the .net backend and later for the java and csharp grades.
Now that the .net backend is ancient history and the java and csharp grades
are established, that purpose is gone, and for every other purpose,
hlc is better because it is simpler and faster.

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.

stage 2 library directories. The reason for the restriction
to the library directory is that any problems affecting the

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.

Since the missing_interface_import test case tests error messages
generated during an invocation of mmc --make-interface, add the

Use trail segments by default in trailing grades.
Until now, we have supported two variants of trailing grades, those that use a
fixed-size trail (.tr) and those that use trail segments (.trseg). This change
removes support for fixed sized trails, and renames the .trseg grade component
to .tr. The .trseg grade now acts a synonym for .tr; it is deprecated, since we
intend to eventually delete it. Until then, the behavior of the old .tr grade
component should be available, though to developers only, by compiling the
whole system with EXTRA_CFLAGS = -DMR_USE_FIXED_SIZE_TRAIL.
runtime/mercury_conf_param.h:
Delete the MR_TRAIL_SEGMENTS macro. Its effect is now implied by
MR_USE_TRAIL, unless a new macro, MR_USE_FIXED_SIZE_TRAIL, is defined.
Developers can use this new macro to disable trail segments, should the
need for doing that arise.
runtime/mercury_grade.h:
Add a new macro that defines a binary compatibility version number for
trailing; use that in the grade part for trailing.
Use "_trfix" or "_trseg" as the prefix of the trailing part of the
MR_GRADE_VAR depending on if MR_USE_FIXED_SIZE_TRAIL is defined or
not.

MR_USE_FIXED_SIZE_TRAIL is enabled.

Add a workaround for Mantis bug #492.
In debug grades that use global register variables, the generated C code is
triggering an internal error in GCC 9 on x86_64 machines. Force GCC to compile
at -O0 in this case as that seems to be the only workaround for the issue.
scripts/mgnuc.in:
Force GCC to use -O0 in the above case.

Do the same when GCC is invoked directly by the Mercury compiler.
Re-arrange some of the code that applies C compiler bug workarounds
to make this possible.

into that separately.

Improve error messages about unexpected module names, again.
When you get this message, the error may be in the module name that it
reports to be wrong, but it may be in the places that set the compiler's
expectations of what the name of the module should be. This latter is
very likely the case when one moves a module of the Mercury compiler
from one package to another. In such cases, the problems are the old modules
that continue to refer to the renamed module by its old name.
This diff improves the error message by indicating *precisely* the locations
that refer to the old name, since these are the locations that establish the
expectation that is not met.
compiler/module_imports.m:
Change the module_and_imports structure to record, for each imported
or used module, and for each child module, the location of the relevant
":- import_module" or ":- include_module" declaration(s).
compiler/deps_map.m:
When tracing references from module A to module B.C (either because
A imports B.C, or because A = B and A includes C), record the location
of the ":- import_module" or ":- include_module" declaration as a source
of the expectation that any file that contains module C will have
B.C as module C's fully qualified name. Since a module is usually imported
by more than one other module, there may be several sources of such
expectations.
compiler/parse_module.m:
Change the wording of the error message to reflect the change in what
the context denotes.

Fix error creating temporary archive with --restricted-command-line.
With `--restricted-command-line' we generate a temporary archive file name with `io.make_temp_file' then run `ar' to create the archive. `ar' sees that the archive file already exists (it is empty), tries to detect its format, and fails. The solution is to delete the temporary file before calling `ar'. Fixes Mantis bug #424. compiler/compile_target_code.m: As above. Add "mtmp" prefix to the temporary archive file name. |

Fix the operation of --rebuild.
This fixes mantis bug #404. compiler/compile_target_code.m: compiler/make.dependencies.m: Use the value of the rebuild option, not the op_mode, to make decisions about executing operations that even when timestamps don't call for them. This fixes the bug, because unlike the op_mode, the value of the option isn't overridden by setting the invoked_by_mmc_make option when recomputing the op_mode. compiler/make.program_target.m: compiler/make.util.m: Reset the rebuild option, not the op_mode, since this is what matters now. compiler/op_mode.m: Take the value of the --rebuild option out of the op_mode, since it is not needed *there* anymore. Note that --rebuild still implies --make, so the rebuild option still does play a role in selecting the op_mode. (This was the original motivation for its inclusion in the op_mode in the first place.) This is why its value matters when converting an op_mode back into its original option string. Fix the copyright years. compiler/options.m: Since the rebuild option isn't stored in the op_mode anymore, give it back its original, non-op_mode internal name. compiler/handle_options.m: compiler/mercury_compile_main.m: Conform to the changes above. |

Make the predicates that find files handle streams explicitly.
compiler/file_util.m:
The predicates in this module that find the file containing a Mercury
module used to allow the caller to specify that if the file can be
successfully opened, then the current input stream should be set to
the resulting stream. This meant that callers had to save the original
current input stream *before* calling this predicate, and later restore it,
*without* anything in between that would signal to readers of the code
that the current input stream had ever been changed.
Replace each of these predicates with two predicates. One returns
the stream as an explicit part of an output argument, letting the caller
do with the stream what it wished (in some cases, that would mean
using it in I/O operations as *explicitly* passed parameters, which
would not require touching the identity of the current input stream),
giving it the responsibility to close the stream when it is done using it.
The other would close the stream immediately, not letting the caller know
that the file was ever opened. The two versions are distinguised both
by name and by return type.
compiler/find_module.m:
Make the same change to search_for_module_source. (This predicate was
the motivation for this change, because unlike the predicates in
file_util.m, its signature did NOT provide readers with any sort of clue
that the searched-for file would actually be opened, and that the
resulting stream would become the new current input stream.)
Clarify the code that tries to find the source file for a module
by dropping qualifiers from the module name by (a) giving the predicate
a more explicit name, and (b) separating the search from the code
that handles the failure of the search.
compiler/parse_module.m:
compiler/read_modules.m:
Change part of the interface between these two modules. This used to be
that code in read_modules.m passed closures to parse_module.m for it
to invoke, closures whose predicates were always one of the predicates
affected by the changes above. Simplify the interface by making
read_modules.m invoke those predicates directly, and simply pass
the results.

io.make_temp now reterns a result rather than throw exceptions
The make_temp predicates would throw an exception if they were unsuccessful, New versions of make_temp/3 and make_temp/5 have been created (named make_temp_file). make_temp/3 and make_temp/5 have been marked as obsolete. make_temp_directory/3 and make_temp_directory/5 have been modified directly as they are very new. This closes bug #408 Some routines in compiler/compile_target_code.m used the name returned by make_temp and added a suffix before using the resulting file, this could create unnecessary temporary files that I believe were never cleaned up.

Remove the .regparm and .picreg grade components.
For picreg, this is only the first half of the change; it deletes code
that generates references to this grade component. When this diff has been
installed on all our machines, will come the second half, which will delete
the code that understands references to picreg. The delay is needed because
your current installed compiler is still generating such references.
runtime/mercury_grade.h:
Remove both regparm and picreg as grade components.
doc/user_guide.texi:
Remove the (commented out) documentation of picreg; regparm had
no documentation to delete.
runtime/mercury_std.h:
Remove the small bit of code that implemented regparm.
runtime/mercury_conf_param.h:
Don't define MR_PIC_REG.
runtime/machdeps/i386_regs.h:
runtime/mercury_conf_bootstrap.h:
Remove references to picreg.
scripts/canonical_grade.sh-subr:
scripts/init_grade_options.sh-subr:
scripts/mgnuc.in:
scripts/parse_grade_options.sh-subr:
Keep in place the code that accepts picreg grade components,
but make them do nothing. Mark such do-nothing code so that
it can be deleted when this first-half diff has been bootstrapped.
configure.ac:
Delete the autoconfigured variable EXT_FOR_LINK_WITH_PIC_OBJECTS,
which could be set to either 'lpic_o' or just 'o', because it is now
*always* the latter.
scripts/Mercury.config.bootstrap.in:
scripts/Mercury.config.in:
Remove code that transmitted the value of EXT_FOR_LINK_WITH_PIC_OBJECTS
to the compiler via the --link-with-pic-object-file-extension option.
compiler/options.m:
Keep the --link-with-pic-object-file-extension and --pic-reg options,
but mark them for deletion in the second half of this change.
compiler/compile_target_code.m:
Change the code that dealt with the value of the
--link-with-pic-object-file-extension and --pic-reg options to assume
that the former is always the same as the non-pic file extension,
and that --pic-reg is never needed. The former means that we don't need
to handle link_with_pic as a separate category of object files from
just plain non_pic.
compiler/compute_grade.m:
Keep accepting picreg grades, but mark the code that does this
for deletion.
compiler/make.program_target.m:
compiler/make.module_target.m:
compiler/make.program_target.m:
compiler/make.util.m:

Use the op_mode, not the options that help determine it.
The options that help determine the op_mode are only sort-of mutually
exclusive; in some cases, more than one can be set. Using the op_mode
instead of the options themselves means that we are using the result
of the process (in op_mode.m) that resolves conflicts between them.
Another benefit is that in some places in the code, many op_modes
have already been processed, which means that the set of remaining op_modes
is a reasonably small set.
compiler/options.m:
Give all the options that op_mode.m uses to compute the op_mode
new internal names. (The user-visible names are not affected.)
Each new internal name is the old internal name with an added
"only_opmode_" prefix, indicating that the option should not be used
for any purpose other than computing the op_mode.
Change the documentation of the --generate-module-order and --imports-graph
options. (See handle_options.m below for the reason.)
doc/user_guide.texi:
Change the documentation of the --generate-module-order and --imports-graph
options, as in compiler/options.m.
compiler/handle_options.m:
Delete implications that set the values of options that help decide the
op_mode, since those implications used to be executed *after* we decided
the op_mode. Replace each of their functionalities with something else.
For the implication from --rebuild to --make, the replacement is
new code in op_mode.m (see below).
For the implication from --invoked-by-mmc-make to --no-make,
the needed replacement code was already in op_mode.m.
For the implications from --generate-module-order and --imports-graph
to --generate-dependencies, do not replace them. Instead, document that
they are effective only if the op mode is generating dependencies.
This goes against the current documentation of --generate-module-order,
though not of --imports-graph (the help message for --imports-graph
is silent on its relationship with --generate-dependencies). However,
the new documented (and implemented) behavior is actually more useful,
since it allows both options to be specified in Mmakefiles or
Mercury.options files, have them be acted on when making dependencies,
but not get error messages about incompatible op mode options.
However, it does mean that "mmc --generate-module-order x.m" would
now try to compile x.m while ignoring the option, whereas previously
it would implicitly act as if the command line were "mmc
--generate-dependencies --generate-module-order x.m". And similarly
for --imports-graph.
Simplify the code that disables smart recompilation when it is not
relevant.
NEWS:
Mention the changes to --generate-module-order and --imports-graph.
compiler/op_mode.m:
Make the opm_top_make functor take an argument that says whether we
are forcing rebuilds or not. The --rebuild option implies we are;
the --make option without --rebuild implies we are not. This replaces
the deleted implication in handle_options.m.
Conform to the name changes in options.m.

In a few places in make.*.m, replace code that sets op_mode options
(temporarily, for the duration of an operation) with code that sets
the op_mode itself.
compiler/globals.m:
Add the now-needed capability to set the op_mode.

Fix bug #388.
Doing 'sudo make install' on Linux with Java 7 or later results in the installed
standard library jars being owned by the root user (which is fine) and with
permissions 0600 (which is not). This is occurring because as part of building
the library jars we create a jar index using the 'jar -i' command. Doing so
creates a temporary file with the above permissions and the installed version
inherits those. Building the index is only useful for executable jars anyway
and the Mercury compiler never builds those, so the fix is to simply not build
the index.
This fix is due to Sebastian Godelet.
compiler/compile_target_code.m:
As above.

Move the code that computes the grade to a new module.
compiler/compute_grade.m:
New module containing all the code previously in handle_options.m
that concern grades.
compiler/libs.m:
compiler/notes/compiler_design.html:
Include and document the new module.
compiler/compiler_util.m:
Since both handle_options.m and compute_grade.m now need to be able
to record errors, move the predicates that handle_options.m used to use
for this purpose to this module, which already contains related predicates.
Generalize the moved predicates, so they can be used from phases other than
option processing.

Optimize the representation of foreign imports.
compiler/prog_data.m:
A foreign_import_module_info structure used to record not just what
module's target language header file is imported in what target language,
but also a context associated with that import, which was set to the
context of the compiler-generated `:- pragma foreign_import_module'
declaration in the .opt file we read it in from. However, we never did
anything useful with this context, and took advantage of that fact
by setting that field to dummy values in pretty much all the
foreign_import_module_info structures created by the compiler.
Since the target language code we generate may need to import the same
target language header file for many different reasons, it is very
unlikely that there is ever going to be a *single* context we may
ever want to associate with the import of one header for one language.
Therefore delete the context field from foreign_import_module_infos.
After this deletion, there is no point in keeping around multiple
foreign_import_module_infos for the same target language / module name
combination. Instead of a set of such pairs, use a representation
that stores a set of imported module names for each of the possible
target languages, since this makes operations faster.
Provide predicates for the operations on the new foreign_import_modules
type that are needed in more than one place.
compiler/prog_item.m:
Avoid having the pragma_info_foreign_import_module type being a duplicate
of the now slimmed-down foreign_import_module_info type by making the
former a wrapper around the latter. (One could replace the former
by the latter, but the current arrangement costs nothing at runtime,
and keeps the documentation of this pragma next to the documentation
of the related pragmas.)

Conform to the above changes. In many places, we can avoid such things as
(a) filtering all foreign_import_module_infos looking for given languages,
or (b) converting from cords to lists to sets, operating on the sets,
and converting the result back to lists and maybe to cords.
compiler/intermod.m:
As above, but also order the source code of the main predicates
of this module in the same order as their invocation, and give some
of them more meaningful names.
