Carve term_context.m out of term.m.
library/term.m:
library/term_context.m:
As above.
Rename the term.context type as term_context.term_context, with
term.context now being defined as an equivalence type.
Replace the context_init function and predicate and the dummy_context_init
function with just one function: dummy_context. This name includes
the important part (the fact that it return a *dummy* context) and deletes
the nonimportant part (dummy contexts are just about never updated,
so the function does not really "initialize" them).
Reduce function/predicate pairs that do the same thing to just a function.
library/MODULES_DOC:
library/library.m:
Add the new module to the list of standard library modules.
NEWS:
Mention the new module, and the obsoleting of the moved predicates
and functions in term.m.

More changes making using var_tables the default.
compiler/goal_util.m:
Add a "_vs" suffix to the names of predicates that use varsets, and
delete the "_table" suffix from the names of predicates that use
var_tables.
compiler/hlds_out_pred.m:
Delete one of two predicates that write out var tables, and use only
the other one.
compiler/prog_util.m:
Delete make_n_fresh_vars_vt, since it put dummy information in
new var_table_entries, requiring them to be filled in with real info later.
All users of it switched to constructing var_table_entries with
real information from the start.

Make polymorphism pass work only on var_tables.
compiler/polymorphism.m:
compiler/polymorphism_info.m:
compiler/polymorphism_lambda.m:
compiler/polymorphism_type_class_info.m:
compiler/polymorphism_type_info.m:
While some of the other passes that made use of it still used vartypes,
polymorphism used var_dbs, which are either vartypes or var_tables.
Now that all those other passes use only var_tables, make polymorphism
use only var_tables as well. Though it handles clauses_infos which
still use vartypes, those vartypes have been completely filled in
by typechecking before polymorphism is ever invoked.
compiler/var_table.m:
Provide a predicate to set the name of a variable in a var_table,
as well as in a var_db, since polymorphism now needs this.
compiler/goal_util.m:
compiler/make_goal.m:
Where a predicate had two versions, one using vartypes and one using
var_tables, and the vartypes version is not needed anymore, delete that
version, and reuse its name for the var_table version.

compiler/recompute_instmap_deltas.m:
compiler/type_util.m:
For predicates which had both varset/vartypes and var_table versions,
but the former is not used anymore because all its callers have been
switched to the latter,
- delete the former, and
- rename the latter to the name of the former.
In goal_util.m, switch two currently-unused predicates to use var_tables
instead of varsets/vartypes, in case they are needed again.

Likewise replace define_new_pred with define_new_pred_vt, but also

compiler/continuation_info.m:
Convert another data structure used by these passes to store var_tables
instead of varsets/vartypes.
Get the callers of some predicates to pass them just the data they need,
instead of bigger structures from which they have to extract what they
need. For now, extracting var_tables from proc_infos is expensive.
And even if it were cheap, it is better for the caller to do it once
per procedure than for it do be done several times per procedure.
Improve the argument order of some predicates.
Fix a copy-and-paste bug in a sanity test, which tested stack vars'
offsets twice: one test should have been (and now is) for frame vars.
compiler/prog_rep.m:
Convert another data structure used by these passes to store var_tables
instead of varsets/vartypes.

Fix a very old bug in a comment.
compiler/code_info.m:
Get the caller of code_info_init, proc_gen.m, to pass it a var_table,
instead of computing it in code_info_init. This is because proc_gen.m
now needs it too.

Use var_tables in lco.m, and when dumping goals.
Since this is the first converted module that dumps out goals when
debugging trace flags are enabled, this required generalizing the code
that does that, to take either varsets or var_tables as a means of
specifying the names of variables. We do this via a new type,
var_name_source, which contains either a varset or a var_table.
Almost all of this diff is there to implement this generalization.
A large part of it affects code in the parse_tree package that we use
to write out the parts of HLDS goals that are defined by types defined
in that package. Since we want to avoid making any part of the parse_tree
package dependent on the hlds package, this required defining the
var_name_source type in the parse_tree package, which in turn requires
var_table.m to be in that same package.
compiler/lco.m:
Convert this module to use var_tables instead of varsets and vartypes.
compiler/var_table.m:
Move this module from the hlds package to the parse_tree package.
To make this, possible, move the parts that required access to the HLDS
to hlds_pred.m, from where it was usually invoked.
Export some utility predicates to allow the moved code to work
in hlds_pred.m without access to the actual definition of the
var_table type.
Define the var_name_source type.
Add some utility functions for use by code writing out variable names.
compiler/hlds_pred.m:
Add the code moved from var_table.m.
compiler/vartypes.m:
Move this module from the hlds package to the parse_tree package,
for symmetry with var_table.m. It did not depend on being in hlds
in any way.
compiler/hlds.m:
compiler/parse_tree.m:
Move vartypes.m and var_table.m from the hlds package
to the parse_tree package.
compiler/hlds_out_goal.m:
Change all the predicates in this module to take a var_name_source
instead of a prog_varset.
Fix some comments.
compiler/hlds_out_util.m:
Change some of the predicates in this module (those called from
hlds_out_goal.m) to take a var_name_source instead of a prog_varset.
compiler/parse_tree_out_term.m:
Provide variants of some existing predicates and functions that take
var_name_sources instead of varsets. The code of the copies
duplicates the logic of the originals, though I hope that this
duplication can be done away with at the end of the transition.
(The best solution would be to use a typeclass with methods
that convert vars to their names, but we would want to ensure
that the compiler can specialize all the affected predicates
and functions to the two instances of this typeclass, which is
something that we cannot do yet. In the meantime, the lack of
any generalization in the old versions preserves their performance.)
tools/sort_imports:
tools/filter_sort_imports:
A new tool that automatically sorts any occurrences of consecutive
":- import_module" declarations in the named files. The sorting is done
in filter_sort_imports; sort_imports loops over the named files.
After automatically replacing all occurrences of hlds.{vartypes,var_table}
in import_module declarations with their parse_tree versions, the updated
import_module declarations were usually out of order with respect to
their neighbours. I used this script to fix that, and some earlier
out-of-order imports.

Use var_tables in more of the later passes.
compiler/add_heap_ops.m:
compiler/add_trail_ops.m:
compiler/float_regs.m:
compiler/lambda.m:
compiler/mark_tail_calls.m:
Convert these passes to use var_tables instead of varsets and vartypes.
compiler/hlds_pred.m:
Provide predicates to get and set "the var_table" of a procedure.
The proc_info still stores varsets and vartypes, but these new predicates
do the required conversions between representations. Likewise, provide
a version of proc_info_create that takes a var_table argument instead
of a varset and vartypes arguments. The new predicates should reduce
the need for such conversions to be done elsewhere during the transition.
compiler/var_table.m:
Provide a predicate to turn a var_table back into
a <varset, vartypes> pair.
Provide two transitional types, var_db and var_type_source, that
provide either
- the functionality of both a varset and a vartypes, or
- just the functionality of a vartypes,
using either those structure(s), or a var_table.
Make it possible to allocate new variables from a var_table,
by including in it a counter that takes on the role played by
the var_supply in varsets.
Provide a predicate to look up the types of several variables at once.
Provide a way to construct a var_table from a reverse sorted assoc list.
compiler/vartypes.m:
Provide a way to construct a var_table from a reverse sorted assoc list,
to allow code to operate the same way on vartypes as on var_tables.
library/varset.m:
Provide predicates to make the changes in var_table.m possible.
They have to be exported, but they are in the second interface section,
so they are not publicly documented.
compiler/quantification.m:
compiler/recompute_instmap_deltas.m:
compiler/goal_util.m:
Provide versions of some exported predicates that take var_tables
instead of varsets and vartypes, for use by the modules above.
Rationalize the argument order of some predicates.
compiler/instmap.m:
Generalize some existing predicates to take type information
from either vartypes or var_tables, using a transitional mechanism
now provided by var_table.m.
Rationalize the argument order of some predicates.
compiler/inlining.m:
Fix an unrelated bug that just happened to be tickled by the
rest of this diff. When inlining a call, set the flag that calls
for rerunning determinism analysis on the procedure in which the
inlining takes place if the call has an argument variable that
does not occur outside the call. We need to do this because
ignoring the last output argument(s) of a call can reduce
the max possible number of solutions of the call to one.
compiler/set_of_var.m:
Provide a predicate needed by the fix in inlining.m.
compiler/prog_type.m:
Give some predicates meaningful names, and create versions that
return the same info in a different form (set instead of list).

Give more meaningful names to two predicates.
compiler/goal_util.m:
Rename generate_simple_call to generate_plain_call and
generate_foreign_proc to generate_call_foreign_proc,
since they generate plain_call and call_foreign_proc HLDS goals
respectively. (And the latter most definitely does not generate
foreign_procs themselves.)

Encode the arity kind in the type in pred lookups.
compiler/pred_table.m:
Some predicates in this module have traditionally taken an arity argument
that *included* function result arguments, while others took an arity
arguments that *excluded* function result arguments. While the difference
was documented, it was not enforced in the types. Change this by
switching the two kinds of arities to pred_form_arities and user_arities
respectively.
Change the internal data structures to specify in the types
that they operate on user_arities.
Change the operation of lookup_builtin_pred_proc_id as part of the
change to goal_util.m (described below).
compiler/goal_util.m:
When looking up the pred_info of a builtin, callers used to pass to the
predicates that did that (generate_simple_call and generate_foreign_proc)
a list of the arguments of the call without specifying which arguments
were type_info/typeclass_info arguments added by polymorphism.
This meant that the length of the argument list was *not* necessarily
the called predicate or function's pred form arity, but could exceed it
by the number of arguments added by polymorphism. The only reason this
worked was because the lookup_builtin_pred_proc_id procedure they used
to look up the named predicate in the pred table compensated for it
- by doing a lookup on the original arity plus one, if the lookup on the
original arity failed, and
- in all the calls to generate_simple_call and generate_foreign_proc,
the number of arguments added by polymorphism was either zero or one.
Nevertheless, the system was fragile. It could have broken either
- because when looking up the arity that included a type_info argument,
(e.g. one typeinfo and two original args) the lookup could have found
a false match (a predicate with the same name with three original args),
- or because a new call to a new builtin could need to specify two or more
arguments added by polymorphism.
Fix this issue by
- requiring calls to generate_simple_call and generate_foreign_proc
to pass the arguments added by polymorphism separately, so the number
of the original arguments specifies the predicate's pred_form_arity, and
- deleting the code in lookup_builtin_pred_proc_id that tried to
compensate for the presence of an "unannounced" typeinfo argument.
compiler/analysis.m:
Change the type of a slot in a structure from arity to pred_form_arity,
since that seems to have been how that slot was used.

Break up inst_util.m and mode_util.m.
This step significantly improves module cohesion.
compiler/inst_abstract_unify.m:
New module carved out of inst_util.m, which does abstract unifications
on insts.
compiler/inst_merge.m:
New module carved out of inst_util.m, which merges insts.
compiler/inst_lookup.m:
New module carved partly out of inst_util.m and partly out of mode_util.m,
which looks up insts in the module_info, and then possibly expands out
the result.
compiler/mode_test.m:
New module carved out of mode_util.m, whose predicates
perform tests on modes.
compiler/mode_top_functor.m:
New module carved out of mode_util.m, which computes top_functor_modes
from modes.
compiler/inst_mode_type_prop.m:
New module carved out of mode_util.m, which propagates type information
into both insts and modes.
compiler/recompute_instmap_deltas.m:
New module carved out of mode_util.m, which recomputes goals'
instmap_deltas.
compiler/inst_test.m:
Move here the predicates in inst_util.m that perform tests on insts.

Delete the code that this diff moves to other modules.
compiler/check_hlds.m:
Add the new modules to the check_hlds package, the package that also
contains inst_util.m and mode_util.m. (Some of these modules could
be argued to fit better in the hlds package, but moving them there
would not be desirable while they depend on code that is still in the
check_hlds package.)

Fix nonlocal typeclass_infos in rhs_lambda_goals.
This fixes github bug #98. compiler/polymorphism.m: Compiling gh98.m used to cause a compiler crash when the compiler tried to look up info about a typeclass_info variable that was needed in a call inside a lambda goal, but was not created inside the lambda goal. It should therefore have been listed as a nonlocal of the lambda goal, but it was not, because none of the variables inside the lambda goal had the typeclass constraint represented by that typeclass_info var on their types. And since later invocations of quantification may reduce, but may not expand, the set of nonlocals in a rhs_lambda_goal (as opposed to the nonlocals set of the unification whose RHS consists of that rhs_lambda_goal), this problem stuck. Fix this underestimation of the final lambda nonlocals set by including in it all typeinfo and/or typeclass_info vars in the updated lambda goal. Since this may then result in an overestimation, set a flag to force a requantification of the whole procedure body once its polymorphism transformation has been completed. compiler/polymorphism_info.m: Add a flag to force requantification. compiler/goal_util.m: Fix a misleading predicate name. compiler/hlds_goal.m: Fix documentation of rhs_lambda_goal. compiler/hlds_out_goal.m: Fix a layout problem in HLDS dumps. compiler/hlds_pred.m: compiler/lambda.m: Fix misleading variable names. tests/valid/gh98.m: Add the github test case. tests/valid/Mmakefile: Enable the new test case. |

Replace ten int cons_ids with one.
We currently have one function symbol in the cons_id type for each
of our ten types of integer constants: signed vs unsigned, and
word-sized, 8-bit, 16-bit, 32-bit and 64-bit. In most places in the compiler,
these are all treated the same, and it gets tedious to have to write
the same logic ten times. This diff therefore changes things so that
the distinction between int constants of these ten types is pushed
to one level lower than the cons_id type.
compiler/prog_data.m:
Replace the ten cons_ids {int,uint}{,8,16,32,64}_const with just one,
some_int_const, whose argument now has those function symbols.

Parse and check coerce expressions.
This change implements parsing, typechecking, and modechecking of
"coerce" expressions from my subtypes proposal, i.e. coerce(Term).
Backends currently will abort if asked to generate code for coercions,
as subtypes do not yet share data representations with their base types,
so most coercions would lead to crashes at runtime anyway.
----------------
compiler/hlds_goal.m:
Add new type of generic_call to represent coerce expressions.
compiler/hlds_pred.m:
Add new generic_call_id for coerce expressions.
compiler/superhomogeneous.m:
Treat var-functor unifications of the form "Var = coerce(Term)"
as special, producing coerce generic_calls.
----------------
compiler/type_assign.m:
Add a field to type_assign to hold coerce constraints to be checked,
or known to be unsatisfiable, in the given type assignment.
compiler/typecheck.m:
compiler/typecheck_errors.m:
Implement typechecking of coerce expressions.
compiler/prog_type.m:
Add a predicate type_is_ground_except_vars.
----------------
compiler/check_hlds.m:
Add new module modecheck_coerce.
compiler/modecheck_coerce.m:
Implement modechecking of coerce expressions.
compiler/modecheck_goal.m:
Call modecheck_coerce at a coerce generic call.

Flatten the unify_mode structure.
compiler/hlds_goal.m:
Change the unify_mode structure from
unify_modes_lhs_rhs(from_to_insts(LI, LF), from_to_insts(RI, RF))
to

(4 words vs 6), though the performance improvement is too small
to measure.
It should also require writing fewer function symbols in code.

Add builtin 64-bit integer types -- Part 1.
Add the new builtin types: int64 and uint64.
Support for these new types will need to be bootstrapped over several changes.
This is the first such change and does the following:
- Extends the compiler to recognise 'int64' and 'uint64' as builtin types.
- Extends the set of builtin arithmetic, bitwise and relational operators
to cover the new types.
- Adds the new internal option '--unboxed-int64s' to the compiler; this will be
used to control whether 64-bit integer types are boxed or not.
- Extends all of the code generators to handle the new types.
- Extends the runtimes to support the new types.
- Adds new modules to the standard library intend to contain basic operations
on the new types. (These are currently empty and not documented.)
There are bunch of limitations marks with "XXX INT64"; these will be lifted in
part 2 of this change. Also, 64-bit integer types are currently always boxed,
again this limitation will be lifted in later changes.

Add builtin 8, 16 and 32 bit integer types -- Part 1.
Add the new builtin types: int8, uint8, int16, uint16, int32 and uint32.
Support for these new types will need to be bootstrapped over several changes.
This is the first such change and does the following:
- Extends the compiler to recognise 'int8', 'uint8', 'int16', 'uint16', 'int32'
and 'uint32' as builtin types.
- Extends the set of builtin arithmetic, bitwise and relational operators to

- Extends all of the code generators to handle new types. There currently lots
of limitations and placeholders marked by 'XXX FIXED SIZE INT'. These will
be lifted in later changes.
- Extends the runtimes to support the new types.
- Adds new modules to the standard library intended to hold the basic
operations on the new types. (These are currently empty and not documented.)

Make each SCC in the dependency graph a set, not a list.
This is to make the data type follow the inherent semantics of SCCs
more closely, and enforce the invariant that a procedure can appear
in the SCC only once.
Also, rename the list of SCCs from "dependency_ordering", which does
not give a clue about *which way* the SCCs are ordered, to "bottom_up_sccs",
which does.
compiler/dependency_graph.m:
Make the changes described above.
Document why we reverse the list generated by digraph.atsort.
library/digraph.m:
Document the order in which digraph.atsort returns the list of SCCs.
Note that the last step of atsort is to reverse the list, which
its caller in compiler/dependency_graph.m will then immediately
re-reverse.
Document the order in which digraph.tsort and digraph.dfs return
a list of items.
Give some variables more meaningful names, and make the argument order
of some predicates conform to our conventions.
compiler/hlds_out_module.m:
Add code to print out the dependency info in the module_info, if asked.
doc/user_guide.texi:

Make the same changes for hlds_dependency_info as dependency_graph.m
did to just plain dependency_info.

Add a new language construct, the disable_warnings scope.
Its syntax is
disable_warnings [warning_category1, ...] Goal
Its semantics is identical to Goal's semantics, with the only difference
being that the compiler will not generate warnings belonging to the listed
categories for code inside Goal.
At the moment, we support the disabling of two warning categories:
singleton variable warnings, and warnings about recursive calls that are not
*tail* recursive. However, the documentation of the latter is commented out
until we use the same code for generating such warnings regardless of what
backend generates code.
doc/reference_manual.texi:
Document the new language extension.
NEWS:
Mention the new language extension.
library/ops.m:
Make "disable_warnings" (and its "disable_warning" variant) binary prefix
operators, as required for the syntax of the new scope.
compiler/prog_item.m:
Add disable_warnings_expr as a new kind of goal in the parse tree.
compiler/hlds_goal.m:
Add disable_warnings as a new kind of scope goal in the HLDS.
compiler/prog_data.m:
Add a type that represents the set of warnings that may be disabled.
This type cannot be in prog_item.m, because it is needed by the HLDS,
and we don't want the HLDS to depend on prog_item.m.
compiler/parse_goal.m:
Parse the new kind of goal, transforming it from source code to parse tree.
compiler/goal_expr_to_goal.m:
Transform the new kind of goal from parse tree to HLDS.
compiler/prog_out.m:
compiler/parse_tree_out_clause.m:
compiler/hlds_out_goal.m:
Output the new kinds of parse tree and HLDS goals.
compiler/make_hlds_warn.m:
Disable singleton variable warnings when the new scope asks for that.
compiler/mark_tail_calls.m:
Disable warnings about non-tail-recursive recursive calls
when the new scope asks for that.
Improve a warning message.
compiler/ml_tailcall.m:
Document why this sort-of-duplicate implementation of the
warnings about non-tail-recursive recursive calls cannot respect
the new scope. (I believe this sort-of-duplicate code should be deleted.)
Improve the same warning message as in mark_tail_calls.m.

Wrap a disable_warnings scope around one of the non-tail-recursive
recursive calls we used to get a warning about, and expect that
we don't get this warning anymore. (We still do get this warning in grades
that use ml_tailcall.m instead of mark_tail_calls.m to generate such
warnings, as mentioned above.)
Specify Mercury syntax highlighting for the source file.
Expect the improved wording of a warning.

Add a builtin unsigned word sized integer type -- Part 1.
Add a new builtin type: uint, which is an unsigned word sized integer type.
Support for this new type will need be bootstrapped over several changes.
This is the first such change and does the following:
- Extends the compiler to recognize 'uint' as a builtin type.
- Extends the set of builtin operations to include relational and (some)
arithmetic operations on uints.
- Extends all of the code generators to handle the above. There are some
limitations currently marked by 'XXX UINT'. These will be lifted once
the compiler recognised uint and additional library support becomes
available.
- Extends the runtime to support uints.

existing 'unsigned_le' operation is actually intended for use with signed
values. Rather than attempt to modify its meaning, I have just added new
operations specific to the uint type.

One is the unify_mode, which used to look like this:
(initx -> finalx) - (inity -> finaly)
and other is the uni_mode, which used to look like this:
(initx - inity) -> (finalx - finaly)
Each unification had one unify_mode, and each unification that includes
a function symbol had one uni_mode per argument of that function symbol.
The two forms of mode information looked similar enough to be easily
confusable, but were subtly different. As it turns out, there was no
particular reason for the difference, so this diff eliminates the
uni_mode type, and the difference along with it.
What rationale there was for the uni_mode type was that the two modes
it represented (one for each side of the unification) both had their
initial and final insts directly available. This is not true for modes
in general: a value of the mer_mode type could have the form
"InitInst -> FinalInst" (which this diff renames "from_to_mode(InitInst,
FinalInst)", but could also be a "user_defined_inst(...)", which required
a table lookup to turn it into an initial/final pair of insts. This matters,
because almost all code that processes the modes of unifications
works with the initial and final insts.
This diff therefore creates a new type, from_to_insts, which represents
mode information only in the form of terms such as "from_to_insts(InitInst,
FinalInst)", and makes a unify_mode take two values of this type, not mer_mode,
as arguments.
As discussed on m-rev, this diff also renames the old, deceptively named
"arg_mode" type: its new name is "top_functor_mode".
compiler/prog_data.m:
compiler/hlds_goal.m:
As mentioned above, avoid using "->" as a function symbol, and replace
both -> and - with bespoke function symbols.
compiler/mode_util.m:
Add some utility predicates and functions on the new types, and
delete the old utility routines that operated on uni_modes.
Code that uses the new functions and predicates should have a higher level
of abstraction than the code that used to do the same job "manually".
compiler/*.m:
Conform to the changes above, using the new utility predicates and
functions where relevant. In several cases, this required fixing
confusion of the kind described at the top. In all but one case,
the confusion affected only variable names, but in one case,
deconstruct_functor in make_goal.m, it caused a bug. The bug has
had no effect up till now because deconstruct_functor is called
only from three places: try_expand.m, stm_expand.m, and untupling.m.
The incorrect mode (which was the nonsensical ground -> free)
generated by the code of try_expand.m itself was discarded and
overwritten when try_expand.m invoked the modechecker. (I don't
know whether this bugfix makes that invocation redundant or not.)
The other two modules, stm_expand.m and untupling.m, may do something
similar, but in any case, they don't yet work for other reasons.
(A bootcheck with --untupling causes a compiler abort when compiling
deep_profiler/query.m in stage 2 both without and with this fix.)
Delete no-longer-needed imports of the pair module (and of some other
modules).
Put the arguments of some predicates into a more logical order.
In bytecode_gen.m, replace clauses with disjunctions, and delete the
arguments that this step has revealed to be unused.

Carve four modules out of prog_data.m.
The prog_data.m module is imported by most modules of the compiler; by
359 modules out of 488, to be exact. Yet it has many parts that most of
those 359 modules don't need. This diff puts those parts into four new
modules. The number of imports of these modules:
348 modules import prog_data.m
84 modules import prog_data_foreign.m
62 modules import prog_data_pragma.m
12 modules import prog_data_event.m
5 modules import prog_data_used_modules.m
compiler/prog_data_event.m:
compiler/prog_data_foreign.m:
compiler/prog_data_pragma.m:
compiler/prog_data_used_modules.m:
New modules. They contain the parts of the parse tree that deal
respectively with the specification of events and event sets,
interfacing to foreign languages, pragmas, and the sets of used
(i.e. not unused) modules.

Delete the stuff that is now in the new modules. Put the remaining parts
of the module into a logical order.

Do stricter checking of mode and determinism declarations.
Specifically, we now do three new checks:
BAD_DETISM: We now generate error messages for predicate declarations
that specify a determinism without also specifying argument modes.
BAD_PREDMODE: We now generate error messages for standalone mode declarations
for predicates whose predicate declaration includes modes for the arguments.
BAD_MODE_SECTION: We now generate error messages for standalone mode
declarations that are not in the same section as the predicate's (or
function's) type declaration.
compiler/hlds_pred.m:
Add a slot to the pred_sub_info. If the predicate is explicitly defined by
the user in the current module, this contains the id of the section that
contains its predicate declaration (for the BAD_MODE_SECTION check)
and whether that predicate declaration also had modes for the arguments
(for the BAD_PREDMODE check).
compiler/add_pred.m:
When adding adding new predicate declarations, perform the BAD_DETISM
check, and record the info needed for the BAD_PREDMODE and BAD_MODE_SECTION

Record *all* procedures referred to in deleted goals.
Not just the ones that are called, but also the ones that occurs in lambdas
or whose address is taken. If a procedure is referred to only in e.g. a lambda
goal inside a trace goal with a false compile-time condition, we used to
generate, if --warn-unused-preds was specified, an incorrect warning about
that procedure being unused. This fixes that problem.

Don't import anything in packages.
Packages are modules whose only job is to serve as a container for submodules. Modules like top_level.m, hlds.m, parse_tree.m and ll_backend.m are packages in this (informal) sense. Besides the include_module declarations for their submodules, most of the packages in the compiler used to import some modules, mostly other packages whose component modules their submodules may need. For example, ll_backend.m used to import parse_tree.m. This meant that modules in the ll_backend package did not have to import parse_tree.m before importing modules in the parse_tree package. However, this had a price. When we add a new module to the parse_tree package, parse_tree.int would change, and this would require the recompilation of ALL the modules in the ll_backend package, even the ones that did NOT import ANY of the modules in the parse_tree package. This happened even at one remove. Pretty much all modules in every one of the backend have to import one or more modules in the hlds package, and they therefore have import hlds.m. Since hlds.m imported transform_hlds.m, any addition of a new middle pass to the transform_hlds package required the recompilation of all backend modules, even in the usual case of the two having nothing to do with each other. This diff removes all import_module declarations from the packages, and replaces them with import_module declarations in the modules that need them. This includes only a SUBSET of their child modules and of the non-child modules that import them. |

Split parts of inst_match.m into a new module, inst_test.m
Most modules that imported inst_match did so in order to use
predicates such as inst_is_ground to test properties of insts.
These predicates are split into a new module, leaving the more
complex parts of inst_match to be imported in fewer places.
This makes it easier to change inst_match (for example, to
address mantis bug 264) without unintentional changes to
the rest of the compiler.

New module containing code from inst_match.m.

Report imports shadowed by other imports.
If a module has two or more import_module or use_module declarations
for the same module, (typically, but not always, one being in its interface
and one in its implementation), generate an informational message about
each redundant declaration if --warn-unused-imports is enabled.
compiler/hlds_module.m:
We used to record the set of imported/used modules, and the set of
modules imported/used in the interface of the current module. However,
these sets
- did not record the distinction between imports and uses;
- did not allow distinction between single and multiple imports/uses;
- did not record the locations of the imports/uses.
The first distinction was needed only by module_qual.m, which *did*
pay attention to it; the other two were not needed at all.
To generate messages for imports/uses shadowing other imports/uses,
we need all three, so change the data structure storing such information
for *direct* imports to one that records all three of the above kinds
of information. (For imports made by read-in interface and optimization
files, the old set of modules approach is fine, and this diff leaves
the set of thus *indirectly* imported module names alone.)
compiler/unused_imports.m:
Use the extra information now available to generate a
severity_informational message about any import or use that is made
redundant by an earlier, more general import or use.
Fix two bugs in the code that generated warnings for just plain unused
modules.
(1) It did not consider that a use of the builtin type char justified
an import of char.m, but without that import, the type is not visible.
(2) It scanned cons_ids in goals in procedure bodies, but did not scan
cons_ids that have been put into the const_struct_db. (I did not update
the code here when I added the const_struct_db.)
Also, add a (hopefully temporary) workaround for a bug in
make_hlds_passes.m, which is noted below.
However, there are at least three problems that prevent us from enabling
--warn-unused-imports by default.
(1) In some places, the import of a module is used only by clauses for
a predicate that also has foreign procs. When compiled in a grade that
selects one of those foreign_procs as the implementation of the predicate,
the clauses are discarded *without* being added to the HLDS at all.
This leads unused_imports.m to generate an uncalled-for warning in such
cases. To fix this, we would need to preserve the Mercury clauses for
*all* predicates, even those with foreign procs, and do all the semantic
checks on them before throwing them away. (I tried to do this once, and
failed, but the task should be easier after the item list change.)
(2) We have two pieces of code to generate import warnings. The one in
unused_imports.m operates on the HLDS after type and mode checking,
while module_qual.m operates on the parse tree before the creation of
the HLDS. The former is more powerful, since it knows e.g. what types and
modes are used in the bodies of predicates, and hence can generate warnings
about an import being unused *anywhere* in a module, as opposed to just
unused in its interface.
If --warn-unused-imports is enabled, we will get two separate set of
reports about an interface import being unused in the interface,
*unless* we get a type or mode error, in which case unused_imports.m
won't be invoked. But in case we do get such errors, we don't want to
throw away the warnings from module_qual.m. We could store them and
throw them away only after we know we won't need them, or just get
the two modules to generate identical error_specs for each warning,
so that the sort_and_remove_dups of the error specs will do the
throwing away for us for free, if we get that far.
(3) The valid/bug100.m test case was added as a regression test for a bug
that was fixed in module_qual.m. However the bug is still present in
unused_imports.m.
compiler/make_hlds_passes.m:
Give hlds_module.m the extra information it now needs for each item_avail.
Add an XXX for a bug that cannot be fixed right now: the setting of
the status of abstract instances to abstract_imported. (The "abstract"
part is correct; the "imported" part may not be.)
compiler/intermod.m:
compiler/try_expand.m:
compiler/xml_documentation.m:
Conform to the change in hlds_module.m.
compiler/module_qual.m:
Update the documentation of the relationship of this module
with unused_imports.m.

compiler/hlds_out_module.m:
Update the code that prints out the module_info to conform to the change
to hlds_module.m.

one of the bugs in unused_imports.m. Format the output for instances

compiler/prog_data.m:

compiler/modules.m:
Delete an XXX that asks for the feature this diff implements.

Add some more modules to the list of modules on which the compiler
should be invoked with --no-warn-unused-imports.
compiler/*.m:
library/*.m:
mdbcomp/*.m:
browser/*.m:
deep_profiler/*.m:
mfilterjavac/*.m:
Delete unneeded imports. Many of these shadow other imports, and some
are just plain unneeded, as shown by --warn-unused-imports. In a few
modules, there were a *lot* of unneeded imports, but most had just
one or two.
In a few cases, removing an import from a module, because it *itself*
does not need it, required adding that same import to those of its
submodules which *do* need it.
In a few cases, conform to other changes above.
tests/invalid/Mercury.options:
Test the generation of messages about import shadowing on the existing
import_in_parent.m test case (although it was also tested very thoroughly
when giving me the information needed for the deletion of all the

Carve vartypes.m, prog_detism.m and prog_rename.m out of prog_data.m.
Besides defining most of the types representing the smaller parts of
parse trees (parts smaller than items), prog_data.m also has many utility
predicates that operate on values of these types. Carve the three substantial
clusters of predicates out of prog_data.m, and move them into their own
modules, which are each imported by fewer modules than prog_data.m itself.
compiler/vartypes.m:
New module containing the vartypes type and the predicates that operate
on it. The new module has *much* better cohesion than the old prog_data.m.
The vartypes type does not appear in any parse tree; it is used only
in the HLDS. So make vartypes.m part of the hlds.m package, not
parse_tree.m.
Move three predicates that perform renamings and substitutions on vartypes
here from prog_type_subst.m, since the latter is part of the parse_tree.m
package, and thus doesn't have access to hlds.vartypes. Make private
the service predicate that these three moved predicates used to rely on,
since it has no other callers.
compiler/prog_detism.m:
New module containing utility predicates that operate on determinisms
and determinism components.
compiler/prog_rename.m:
New module containing utility predicates that rename variables in
various data structures.
compiler/prog_data.m:
Remove the stuff now in the three new modules.
compiler/prog_type_subst.m:
Remove the three predicates now in vartypes.m.
compiler/mercury_to_mercury.m:

that referred to vartypes.
compiler/prog_type.m:

compiler/type_util.m:
Move some utility predicates that refer to vartypes from prog_type.m
and builtin_lib_types.m (both part of parse_tree.m) to type_util.m
(part of check_hlds.m).
compiler/parse_tree.m:

Print better contexts for module qualification errors.
Specifically, when we find undefined types in type definitions, say WHERE
the undefined type is (both as line number and as function symbol/arg number,
and field name if present), since the body of the type definition is sometimes
quite big.
compiler/module_qual.m:
When module qualification found an error, it used to get the context
it printed for the error from the mq_info structure, which also contained
the rest of the state of the qualification process. The drawback of this
setup is that the mq_info's record of the error context was updated
only in a few of the places where that context actually changed.
This diff takes the error context out of the mq_info, and passes it
as a separate argument to the predicates that need it. This makes it
really visible if a context is passed onward unchanged even when it
should be updated.
Fix some of these places, and mark the rest with XXXs.
When printing error messages about predicate or function declarations,
the message talked about definitions, not declarations. Fix that.
Put a prog_context inside each function symbol of mq_error_context;
don't require the creation of a separate memory cell for a pair
to link the mq_error_context with the prog_context.
Factor out some common code.
compiler/prog_data.m:
I tried to put a context inside constraints for use in error contexts
in module_qual.m, but that turned out to be a bad idea. Document why.

Add require_switch_arms_{det,semidet,...} to the language.
The new construct looks like this:
require_switch_arms_det [C] (
(
C = 'a',
... compute Out ...
;
C = 'b',
... compute Out ...
)
)
If any of the goals computing Out are not det, the compiler will generate
an error message. The det at the end of the keyword can be replaced
by any of the other seven determinisms, though I don't think either
require_switch_arms_failure or require_switch_arms_erroneous will see much use.
This diff adds only the implementation. I will add the documentation
and the NEWS item after we all had a chance to install this diff and
try it out.
compiler/hlds_goal.m:
Add a scope representing this kind of goal in the HLDS.
compiler/prog_item.m:
Add a goal expression for this kind of goal in the parse tree.
compiler/prog_io_goal.m:
Look for the new kind of goal expression in terms when creating
the parse tree.
Factor out some commonalities between the parsing of the new goal
expression and existing types of goal expressions.
compiler/goal_expr_to_goal.m:
Convert the new kind of goal expression to the new scope in the HLDS.
compiler/det_report.m:
Implement the checks that the new goal type calls for.
Factor out some commonalities between the implementation of the new goal
type and existing goal types.
Move the types and predicates dealing with comparisons of determinisms
from here to prog_data.m, due to the sort-of-bugfix to modecheck_call.m.
compiler/prog_data.m:
Move the types and predicates dealing with comparisons of determinisms
from det_report.m to here. The old code for this was intended for only one
requirement, and did not deal well with comparisons of two determinisms
in which each determinism makes an assertion the other does not make.
Create a way to represent such comparison results.
compiler/modecheck_call.m:
When deciding which mode of a procedure to call, we prefer determinisms
that make more assertions about solution counts. However, when comparing
incomparable determinisms (such as semidet vs multi, each of which makes
an assertion the other doesn't), the algorithm chose based solely
on the ORDER of the modes. We now explicitly prefer modes that promise
lower maximum solution counts, giving less importance to cannot_fail
assertions.
compiler/*.m:
Conform to the change to hlds_goal.m or prog_item.m.
library/ops.m:
Add the new keywords as operators.
tests/hard_coded/require_scopes.{m,exp}:
Extend this test case to test the new construct in the absence of errors.
tests/invalid/require_scopes.{m,exp}:
Extend this test case to test the new construct in the presence of errors.

mdbcomp/sym_name.m:
New module, containing the part of the old prim_data.m that
dealt with sym_names.
mdbcomp/builtin_modules.m:
New module, containing the part of the old prim_data.m that
dealt with builtin modules.
mdbcomp/prim_data.m:
Remove the things that are now in the two new modules.

Remove most non-core predicates from hlds_goal.m.
compiler/hlds_goal.m:
As above.
Put some of the remaining stuff in a more logical order.
compiler/make_goal.m:
This new module contains the predicates, previously in hlds_goal.m,
that construct new goals.
compiler/hlds.m:
compiler/notes/compiler_design.html:
Include the new module.
compiler/goal_form.m:
Move to this existing module the predicates previously in hlds_goal.m
that test whether goals have particular forms (which is the task of
this module).
compiler/*.m:
Conform to the above. Note that no module requires a new import
of BOTH make_goal and goal_form.

Make is_exist_constr a proper type, not a synonym for boolean.
compiler/hlds_goal.m:
The is_exist_constr field of rhs_functor, which used to be represented by
a synonym of boolean. Make this type an enum type.

Allow external files to be included in foreign_decl and foreign_code.
Allow external files to be included in pragma foreign_decl and pragma
foreign_code declarations:
:- pragma foreign_decl("Lang", include_file("Path")).
:- pragma foreign_decl("Lang", local, include_file("Path")).
:- pragma foreign_code("Lang", include_file("Path")).

directory that contains the source file of the module containing the
declaration.
mmc --make takes include_file into account when computing dependencies.
Mmake is unchanged yet.
