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.
compiler/*.m:
library/*.m:
Conform to the changes above.

Store var_tables in proc_infos.
This fixes the performance problem reported in Mantis bug #562. compiler/hlds_pred.m: Instead of storing a varset and a vartypes in each proc_info, store just a var_table. Update the predicates that create or clone procedures accordingly. Where we had operations on proc_infos that had two versions, one operating on a varset/vartypes pair and one operating on var_table, keep only the latter, with the (shorter) name of the former. Delete the arity argument of proc_info_init, because the only valid value of that argument is the length of the list of the argument types. (In other words, this arg has been redundant all along.) Change the operations that create new variables in a procedure to get the caller to specify the (base) name of the new variable up front. Delete the unused predicate proc_info_ensure_unique_names. compiler/type_util.m: Due to the change above, we now construct var_tables during the construction of the HLDS. The code that does that needs to fill in the field that says whether the type of each variable in the table is a dummy type or not. However, at this time, the pass that decides type representations has not been run yet. The code of is_type_a_dummy used to throw an exception in such situations. Change this so that in such situations, is_type_a_dummy returns a placeholder, not-guaranteed-to-be-correct value. Document why this is ok. compiler/post_typecheck.m: Replace the placeholder values in vte_is_dummy fields in all the entries in the var_tables in all (valid) predicates with valid data. (If there are any invalid predicates, the compilation will fail anyway.) The clause_to_proc pass will copy these updated var_tables to be the initial var_tables in procedures. compiler/make_goal.m: Change the operations that create new variables in a procedure to get the caller to specify the (base) name of the new variable up front. This is simpler than the old method, which created new variables without a name, and had the caller give them a name as a separate operation. And since var_tables need this info, get the caller to also specify whether the type is a dummy, if the type is not a builtin type which is known not to be a dummy. compiler/var_table.m: Document the times when the types and is_dummy fields in var_table entries become meaningful. Fix a potential bug: when performing type substitutions in var_table entries, updating a variable's type may change whether that variable is a dummy or not, so recompute that info. It is quite possible that we *never* replace a nondummy type with a dummy type or vice versa, but in the absence of a convincing correctness argument for that proposition, better safe than sorry. Export the previously-private predicate transform_var_table to post_typecheck. Add code to implement the unused predicate deleted from hlds_pred.m: at the time I wrote it, I haven't yet realised that it was unused. The code I wrote here is therefore unused as well, so it is commented out. I did not delete it, because it may be useful later on. compiler/direct_arg_in_out.m: Don't make and split var_tables, since it is no longer needed. compiler/accumulator.m: compiler/add_class.m: compiler/add_clause.m: compiler/add_heap_ops.m: compiler/add_pred.m: compiler/add_special_pred.m: compiler/add_trail_ops.m: compiler/arg_info.m: compiler/build_mode_constraints.m: compiler/bytecode_gen.m: compiler/check_typeclass.m: compiler/clause_to_proc.m: compiler/closure_analysis.m: compiler/code_gen.m: compiler/code_loc_dep.m: compiler/complexity.m: compiler/continuation_info.m: compiler/cse_detection.m: compiler/ctgc.livedata.m: compiler/deep_profiling.m: compiler/default_func_mode.m: compiler/deforest.m: compiler/delay_construct.m: compiler/delay_partial_inst.m: compiler/dep_par_conj.m: compiler/det_analysis.m: compiler/det_report.m: compiler/distance_granularity.m: compiler/equiv_type_hlds.m: compiler/exception_analysis.m: compiler/float_regs.m: compiler/follow_code.m: compiler/goal_mode.m: compiler/goal_path.m: compiler/higher_order.m: compiler/hlds_out_pred.m: compiler/hlds_rtti.m: compiler/hlds_statistics.m: compiler/inlining.m: compiler/intermod.m: compiler/intermod_analysis.m: compiler/introduce_exists_casts.m: compiler/introduce_parallelism.m: compiler/lambda.m: compiler/lco.m: compiler/live_vars.m: compiler/liveness.m: compiler/loop_inv.m: compiler/mark_tail_calls.m: compiler/ml_accurate_gc.m: compiler/ml_args_util.m: compiler/ml_closure_gen.m: compiler/ml_gen_info.m: compiler/ml_proc_gen.m: compiler/mode_errors.m: compiler/mode_info.m: compiler/modecheck_goal.m: compiler/par_loop_control.m: compiler/pd_debug.m: compiler/pd_info.m: compiler/pd_util.m: compiler/polymorphism_info.m: compiler/post_typecheck.m: compiler/proc_gen.m: compiler/proc_requests.m: compiler/purity.m: compiler/push_goals_together.m: compiler/quantification.m: compiler/rbmm.add_rbmm_goal_infos.m: compiler/rbmm.live_variable_analysis.m: compiler/rbmm.points_to_analysis.m: compiler/rbmm.points_to_graph.m: compiler/rbmm.points_to_info.m: compiler/rbmm.region_liveness_info.m: compiler/rbmm.region_transformation.m: compiler/recompute_instmap_deltas.m: compiler/saved_vars.m: compiler/simplify_goal_unify.m: compiler/simplify_info.m: compiler/simplify_proc.m: compiler/size_prof.m: compiler/ssdebug.m: compiler/stack_alloc.m: compiler/stack_layout.m: compiler/stack_opt.m: compiler/stm_expand.m: compiler/store_alloc.m: compiler/structure_reuse.analysis.m: compiler/structure_reuse.direct.choose_reuse.m: compiler/structure_reuse.direct.detect_garbage.m: compiler/structure_reuse.domain.m: compiler/structure_reuse.indirect.m: compiler/structure_reuse.lbu.m: compiler/structure_reuse.lfu.m: compiler/structure_reuse.versions.m: compiler/structure_sharing.analysis.m: compiler/structure_sharing.domain.m: compiler/switch_detection.m: compiler/table_gen.m: compiler/tabling_analysis.m: compiler/term_constr_build.m: compiler/term_constr_initial.m: compiler/term_errors.m: compiler/term_pass1.m: compiler/term_pass2.m: compiler/trace_gen.m: compiler/trailing_analysis.m: compiler/try_expand.m: compiler/tupling.m: compiler/unneeded_code.m: compiler/untupling.m: compiler/unused_args.m: compiler/unused_imports.m: Conform to the changes above. Mostly this means - not passing a module_info to get a var_table out of a proc_info, but - having to pass a module_info to code that either constructs a var_table, or adds entries to a var_table (since we now need the type table to figure out whether variables' types are dummies). |

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.

Get and set varsets/vartypes in proc_infos together.
compiler/hlds_pred.m:
We eventually want to replace the varset and vartypes fields in
each proc_info with a var_table, but it is not practical to do so
at once; it will have to be done gradually, a few modules at most
at a time. During this process, we will need a way either
- to let already converted modules get a var_table out of the proc_info,
and put an updated var_table back into a proc_info, even though
proc_infos still contain varset and vartypes fields, or
- to let not-yet-converted modules get varsets and vartypes out of the
proc_info, and put updated varsets and vartypes back into a proc_info,
even though proc_infos already store a var_table.
The latter cannot be done in two halves (i.e. set the varset half
of the var_table, and then set its vartypes half), and while the former
*can* be done that way, it is more efficient to do them at the same time.
Therefore as a first step, this diff replaces the indiviual getter
and setter predicates of the varset and vartypes fields of proc_info
with a getter that gets both and a setter that sets both.
Put the varset and vartypes next to each other in a structure.

Rename pred_table to pred_id_table.
compiler/pred_table.m:
As above. This addresses half of an old XXX, which is that the two types
defined in this module, predicate_table and pred_table (as it was then)
should have names that (a) say what they do, and (b) are distinct.
Addressing the other half requires a more descriptive but not-too-long
name to replace "predicate_table".
Rename the predicates that operate on the type to follow the name change.
Add a distinguishing prefix to the names of the fields of the
predicate_table type.

Conform to the change in pred_table.m.
Refer to values of the renamed type using a consistent naming scheme.
When the affected code repeats the body of existing helper predicates
for lookup up a pred_info or proc_info, or updating a proc_info
inside a pred_info, or updating a pred_info inside a module_info,
call the helper predicate instead. This makes code shorter and less
cluttered, and the use of the helper predicates for updates automatically
ensures that we don't accidentally update a stale version of the relevant
table. (This has sometimes been a problem in the past.)
In a few places, carve a new predicate for processing one element
of a list out of an existing predicate for processing all list elements.

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.
compiler/inst_util.m:
compiler/mode_util.m:
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.)

Make clause_to_proc a separate pass.
Copying goals from clauses to procedures has to be done after type checking
(which operates on predicates) but before mode checking (which operates on
procedures). Previously, this copying was done within one of the passes
between type and mode checking, to reduce the overall number of passes.
For many years now, it was done within the polymorphism pass.
However, this arrangement has two undesirable consequences.
The first, which was the reason for this change, is that it makes it
much harder to see the effects of the polymorphism pass in HLDS dumps,
since the difference between HLDS dumps before and after the polymorphism
pass contains not just the effects of the polymorphism transformation itself,
but also the population of the goal fields of proc_infos.
The second, which I discovered while doing the change, is that the
polymorphism pass itself is split. It does the vast bulk of its work
before copying clauses to procs, but it does leave some tasks to be done
*after* copying clauses to procs. I don't *know* whether this is
by design or by accident, but I strongly suspect the latter.
compiler/mercury_compile_front_end.m:
Make copying clauses to procedures its own pass.
Make the part of polymorphism that runs *after* copying clauses
to procedures its own pass as well.
compiler/clause_to_proc.m:
Add a predicate that mercury_compile_front_end can call to do its job
on every predicate in the module. The setup we use for imported procedures
is the same as what polymorphism.m used to do for such procedures.
Make some predicate names more specific.
compiler/polymorphism.m:
Don't copy clauses to procs in the middle of the polymorphism
transformation.
Add a predicate that mercury_compile_front_end.m can call to do the
post-copying part of the polymorphism transformation.
compiler/introduce_exists_casts.m:
Add a predicate that polymorphism.m can call to do this module's part of
the post-copying part of the polymorphism transformation.
compiler/mode_ordering.m:
compiler/modes.m:
compiler/proc_requests.m:
Conform to the changes above.

Split clause_to_proc.m into three pieces.
compiler/default_func_mode.m:
compiler/introduce_exists_casts.m:
Carve these two modules out of clause_to_proc.m. The code now in
default_func_mode.m had no connection to the rest of clause_to_proc.m,
while the code now in introduce_exists_casts.m has only a single call
to a predicate defined in the left-over part of clause_to_proc.m.
compiler/clause_to_proc.m:
Remove the code that has been moved elsewhere, and export that one
predicate for introduce_exists_casts.m. This reduces clause_to_proc.m
to less than half its former size.
compiler/check_hlds.m:
Add introduce_exists_casts.m to the check_hlds package.
compiler/hlds.m:
Add default_func_mode.m to the hlds package.
compiler/notes/compiler_design.html:
Document the new modules.
compiler/add_class.m:
compiler/add_clause.m:
compiler/du_type_layout.m:
compiler/make_hlds_passes.m:
compiler/modes.m:
compiler/polymorphism.m:
Conform to the changes above.
