Import only one compiler module per line. Sort the blocks of imports.
Estimated hours taken: 2 Branches: main compiler/*.m: Import only one compiler module per line. Sort the blocks of imports. This makes it easier to merge in changes. In a couple of places, remove unnecessary imports. |

Use sub-modules to structure the modules in the Mercury compiler directory.
The main aim of this change is to make the overall, high-level structure of the compiler clearer, and to encourage better encapsulation of the major components. compiler/libs.m: compiler/backend_libs.m: compiler/parse_tree.m: compiler/hlds.m: compiler/check_hlds.m: compiler/transform_hlds.m: compiler/bytecode_backend.m: compiler/aditi_backend.m: compiler/ml_backend.m: compiler/ll_backend.m: compiler/top_level.m: New files. One module for each of the major components of the Mercury compiler. These modules contain (as separate sub-modules) all the other modules in the Mercury compiler, except gcc.m and mlds_to_gcc.m. Mmakefile: compiler/Mmakefile: Handle the fact that the top-level module is now `top_level', not `mercury_compile' (since `mercury_compile' is a sub-module of `top_level'). compiler/Mmakefile: Update settings of *FLAGS-<modulename> to use the appropriate nested module names. compiler/recompilation_check.m: compiler/recompilation_version.m: compiler/recompilation_usage.m: compiler/recompilation.check.m: compiler/recompilation.version.m: compiler/recompilation.version.m: Convert the `recompilation_*' modules into sub-modules of the `recompilation' module. compiler/*.m: compiler/*.pp: Module-qualify the module names in `:- module', `:- import_module', and `:- use_module' declarations. compiler/base_type_info.m: compiler/base_type_layout.m: Deleted these unused empty modules. compiler/prog_data.m: compiler/globals.m: Move the `foreign_language' type from prog_data to globals. compiler/mlds.m: compiler/ml_util.m: compiler/mlds_to_il.m: Import `globals', for `foreign_language'. Mmake.common.in: trace/Mmakefile: runtime/Mmakefile: Rename the %.check.c targets as %.check_hdr.c, to avoid conflicts with compiler/recompilation.check.c. |

Aditi compilation.
Estimated hours taken: 1200
Aditi compilation.
compiler/options.m:
The documentation for these is commented out because the Aditi
system is not currently useful to the general public.
--aditi: enable Aditi compilation.
--dump-rl: write the intermediate RL to `<module>.rl_dump'.
--dump-rl-bytecode: write a text version of the bytecodes
to `<module>.rla'
--aditi-only: don't produce a `.c' file.
--filenames-from-stdin: accept a list of filenames to compile
from stdin. This is used by the query shell.
--optimize-rl, --optimize-rl-cse, --optimize-rl-invariants,
--optimize-rl-index, --detect-rl-streams:
Options to control RL optimization passes.
--aditi-user:
Default owner of any Aditi procedures,
defaults to $USER or "guest".
--generate-schemas:
write schemas for base relations to `<module>'.base_schema
and schemas for derived relations to `<module>'.derived_schema.
This is used by the query shell.
compiler/handle_options.m:
Handle the default for --aditi-user.
compiler/hlds_pred.m:
compiler/prog_data.m:
compiler/prog_io_pragma.m:
compiler/make_hlds.m:
Add some Aditi pragma declarations - `aditi', `supp_magic', `context',
`naive', `psn' (predicate semi-naive), `aditi_memo', `aditi_no_memo',
`base_relation', `owner' and `index'.
Separate out code to parse a predicate name and arity.
compiler/hlds_pred.m:
Add predicates to identify Aditi procedures.
Added markers `generate_inline' and `aditi_interface', which
are used internally for Aditi code generation.
Add an `owner' field to pred_infos, which is used for database
security checks.
Add a field to pred_infos to hold the list of indexes for a base
relation.
compiler/make_hlds.m:
Some pragmas must be exported if the corresponding predicates
are exported, check this.
Make sure stratification of Aditi procedures is checked.
Predicates with a mode declaration but no type declaration
are no longer assumed to be local.
Set the `do_aditi_compilation' field of the module_info if there
are any local Aditi procedures or base relations.
Check that `--aditi' is set if Aditi compilation is required.
compiler/post_typecheck.m:
Check that every Aditi predicate has an `aditi__state' argument,
which is used to ensure sequencing of updates and that Aditi
procedures are only called within transactions.
compiler/dnf.m:
Changed the definition of disjunctive normal form slightly
so that a call followed by some atomic goals not including
any database calls is considered atomic. magic.m can handle
this kind of goal, and it results in more efficient RL code.
compiler/hlds_module.m:
compiler/dependency_graph.m:
Added dependency_graph__get_scc_entry_points which finds
the procedures in an SCC which could be called from outside.
Added a new field to the dependency_info, the
aditi_dependency_ordering. This contains all Aditi SCCs of
the original program, with multiple SCCs merged where
possible to improve the effectiveness of differential evaluation
and the low level RL optimizations.
compiler/hlds_module.m:
Add a field to record whether there are any local Aditi procedures
in the current module.
Added versions of module_info_pred_proc_info and
module_info_set_pred_proc_info which take a pred_proc_id,
not a separate pred_id and proc_id.
compiler/polymorphism.m:
compiler/lambda.m:
Make sure that predicates created for closures in Aditi procedures
have the correct markers.
compiler/goal_util.m:
Added goal_util__switch_to_disjunction,
goal_util__case_to_disjunct (factored out from simplify.m)
and goal_util__if_then_else_to_disjunction. These are
require because supplementary magic sets can't handle
if-then-elses or switches.
compiler/type_util.m:
Added type_is_aditi_state/1.
compiler/mode_util.m:
Added partition_args/5 which partitions a list of arguments
into inputs and others.
compiler/inlining.m:
Don't inline memoed procedures.
Don't inline Aditi procedures into non-Aditi procedures.
compiler/intermod.m:
Handle Aditi markers.
Clean up handling of markers which should not appear in `.opt' files.
compiler/simplify.m:
Export a slightly different interface for use by magic.m.
Remove explicit quantifications where possible.
Merge multiple nested quantifications.
Don't report infinite recursion warnings for Aditi procedures.
compiler/prog_out.m:
Generalised the code to output a module list to write any list.
compiler/code_gen.m:
compiler/arg_info.m:
Don't process Aditi procedures.
compiler/mercury_compile.m:
Call magic.m and rl_gen.m.
Don't perform the low-level annotation passes on Aditi procedures.
Remove calls to constraint.m - sometime soon a rewritten version
will be called directly from deforestation.
compiler/passes_aux.m:
Add predicates to process only non-Aditi procedures.
compiler/llds.m:
compiler/llds_out.m:
Added new `code_addr' enum members, do_{det,semidet,nondet}_aditi_call,
which are defined in extras/aditi/aditi.m.
compiler/call_gen.m:
Handle generation of do_*_aditi_call.
compiler/llds_out.m:
Write the RL code for the module as a constant char array
in the `.c' file.
compiler/term_errors.m:
compiler/error_util.m:
Move code to describe predicates into error_util.m
Allow the caller to explicitly add line breaks.
Added error_util:list_to_pieces to format a list of
strings.
Reordered some arguments for currying.
compiler/hlds_out.m:
Don't try to print clauses if there are none.
runtime/mercury_init.h:
util/mkinit.c:
scripts/c2init.in:
Added a function `mercury__load_aditi_rl_code()' to the generated
`<module>_init.c' file which throws all the RL code for the program
at the database. This should be called at connection time by
`aditi__connect'.
Added an option `--aditi' which controls the output
`mercury__load_aditi_rl_code()'.
compiler/notes/compiler_design.html:
