Replace simple_call_id with pf_sym_name_arity.
compiler/prog_data.m:
Delete the simple_call_id data type, since it is isomorphic
to the pf_sym_name_arity type, which more clearly specifies
what is stored inside it.
compiler/prog_out.m:
Rename (all three versions of) simple_call_id_to_string to
pf_sym_name_orig_arity_to_string, both to conform to the change
in the input data type, and to emphasize that the resulting string
will contain the *original* arity of functions (which does not include
the return value), which is one less than the arity in the
pf_sym_name_arity structure (which, in accordance with the
convention inside the compiler that the arity is the length
of the argument list, *does* include the return value).
Delete the provision inside simple_call_id_to_string, now
pf_sym_name_orig_arity_to_string, for special handling of the names
of the predicates we use to implement promises, because it seems that
*none* of the call sites to any of the three versions of this function
can actually pass to it the identity of such a predicate. These calls
refer to a predicate or mode declaration item (which promise predicates
do not have), to clause or foreign_proc items (which again, promise
predicates cannot have) or calls to the predicate (promise predicates
cannot be called).
Delete the exported predicate simple_call_id_to_sym_name_arity.
It was called from exactly one place, inside prog_out.m itself,
and this diff inlines that call.
Avoid unnecessary forwarding of work from prog_out.m to error_util.m.
Delete (all three versions of) write_simple_call_id. The changes
below replace all their (few) uses with calls to
pf_sym_name_orig_arity_to_string.
compiler/error_util.m:
Replace the simple_call() error piece with qual_pf_sym_name_orig_arity,
and add a new version unqual_pf_sym_name_orig_arity. Their names
explicitly say that they print the original arities of functions,
also say whether they strip away any module qualification on the
sym_name inside the pf_sym_name_arity. We prefer the unqual version
in situations where the module qualifier is implicit, which usually means
that it must be the same as the name of the module being compiled, because
it reduces visual clutter for readers of error messages.
Put {qual,unqual}_pf_sym_name_orig_arity next to their most closely
related function symbols, {qual,unqual}_sym_name_arity, in the
format_component type. (This yields a few inconsequential changes
in the order of error_specs when sorted.)

Conform to the changes above. Where I am pretty sure that in an error
message, the module qualifier of a name must be the current module,
use unqual_pf_sym_name_orig_arity instead of qual_pf_sym_name_orig_arity.
Add some sanity checks where they seem appropriate.
Replace sequences of io.write_strings with uses of io.format where this
yields clearer code. (This is why there were no remaining calls to
write_simple_call_id.)
Shorten some too-long lines.
In add_pred.m, make the order of some predicate definitions match
the order of the calls to them.

Update all these expected output files. Most changes are due to
predicate and function names no longer being module qualified when
the module qualification is obvious. A few changes are due to the
change in the relative ordering of the function symbols of the
format_component type.
For singleton_test, warn_return and warn_succ_ind in warnings,
the changes to the non-C .exp files were done by hand, so they
may have the wrong white space.

Fix the context of unused import_module error messages.
compiler/module_qual.m:
When printing error messages about modules imported in the interface
but not used in the interface, we used to use the context of the module's
`:- module' declaration, not the context of the bad `:- import_module'
declarations themselves. Fix that, by generating a separate error message
for each unnecessarily interface-imported module, each with its own
context.

Replace the item list with more structured ASTs.
The parts of the compiler that run before the HLDS is constructed used to use
a raw list of items to represent source files (.m), interface files (.int0,
.int3, .int2 and .int) and optimization files (.opt, and .trans_opt).
These lists had structure, but this structure was implicit, not explicit,
and its invariants were never really documented.
This diff changes that. It replaces the item list with FIVE separate types.
Three of these each represent the unprocessed content of one file:
- parse_tree_int represents the contents of one interface file;
- parse_tree_opt represents the contents of one optimization file;
- parse_tree_src represents the contents of one source file.
Two of these each represent the processed contents of one or more files:
- raw_compilation_unit represents the contents of one module in a source file.
(The source file may contain several nested modules; the compilation unit
represents just one.)
- aug_compilation_unit represents the contents of one module in a source file,
just like raw_compilation_unit, but it is augmented with the contents of the
interface and optimization files of the other modules imported (directly or
indirectly) by the original module.
These five separate concepts all used to be represented by the same type,
list(item), but different invariants applied to the structure of those lists.
The most important of those invariants at least are now explicit in the types.
I think it is entirely possible that there are other invariants I haven't
discovered and documented (for example, .int3 files must have stricter
invariants on what can appear in them than .int files), but discovering
and documenting these should be MUCH easier after this change.
I have marked many further opportunities for improvements with "XXX ITEM_LIST".
Some of these include moving code between modules, and the creation of new
modules. However, I have left acting on those XXXs until later, in order to
keep the size of this diff down as much as possible, for easier reviewing.
compiler/prog_item.m:
Define the five new AST types described above, and utility predicates
that operate on them.
In the rest of this change, I tried, as much as possible, to change
predicates that used to take item lists as arguments to make them change
one of these types instead. In many cases, this required putting
the argument lists of those predicates into a more consistent order.
(Often, predicates that operated on the contents of the module
took the name of the module and the list of items in the module
not just as separate arguments, but as separate arguments that
weren't even next to each other.)
Define types that identify the different kinds of interface and
optimization files (.int, .int2 etc). These replace the string suffixes
we used to use to identify file types. Predicates that used to take strings
representing suffixes as arguments now have to specify whether they can
handle all these file types (source, interface and optimization),
or just (e.g.) all interface file types.
We used to have items corresponding to `:- module' and `:- end_module'.
Delete these; this information is now implicit in the structure of the
relevant AST. The parser handles the corresponding terms as markers,
not items; these markers are live only during parsing.
We used to have module_defns corresponding to `:- interface' and
`:- implementation'. Delete these; this information is now also implicit
in the structure of the relevant AST. Delete also, for the same reason,
the module_defns used to mark the starts of sublists in the overall lists
of items whose items came from the interface files or optimization files
of other modules. The former are now markers during parsing. The latter
are never parsed, but are created directly, after parsing has been done.
Delete the pragma type for `:- pragma source_file'. This is never
needed later; it is now a marker during parsing.
Change the internal representation of `:- import' and `:- use'.
It used to store a list of module names, but that list was an actual list
only during parsing; after that, it always had exactly one element.
It now stores one module name, and the parser has a mechanism to convert
one read-in term to more than one item, for use with terms such as
`:- import_module a, b'.
Delete the internal representation of `:- export', which was never
implemented, since if it IS ever implemented, it will almost certainly
be in a different form, which will need different support.
Document some further opportunities for simplification, later.
(This diff is already more than big enough.)
compiler/prog_io_item.m:
Rewrite the top-level part of this module. Instead of returning an item
for every parsed term, distinguish between parsing items that end up
in item lists inside ASTs, and parsing markers that end up creating
the STRUCTURE of those ASTs.
compiler/prog_io.m:
Rewrite the meat of this module. Instead of reading in a simple item list,
we now have to read in three different parse trees with three different
grammars, each of which is more complex than a simple list.
compiler/read_modules.m:
We used to have a map that mapped file names to the contents of those
files. We now need three separate maps, for interface files, optimization
files and source files, due to their separate types.
(We don't actually use the map for optimization files, which seems
to be a potential performance bug. The root cause of that problem
us that while intermod.m and the grab_*modules part of modules.m do
similar jobs, they don't use the same mechanisms.)
Replace the read_module predicate with the predicates read_module_src
and read_module_int, since these now return different types.
To avoid having to create AST-type-specialized variants of
read_module_ignore_errors and read_module_if_changed, give each of
read_module_{src,int} arguments that optionally tell them to ignore errors
and/or to read the module only if changed (though the "and" part of
"and/or" should not be needed.) These options already existed, but
they weren't exported.
compiler/timestamp.m:
Define the type we use for this option in read_modules.
compiler/status.m:
New module, containing mostly
- stuff carved out of hlds_pred.m, which defines the import_status type,
and the predicates that operate on it;
- stuff carved out of make_hlds_passes.m, which defines the item_status
type and the predicates that operate on that; and
- stuff carved out prog_data.m, which defines the section (now
module_section) and import_locn types.
It also contains the new section kinds we now use to represent item blocks
that were imported from interface and optimization files.
compiler/parse_tree.m:
compiler/notes/compiler_design.html:
Add status.m to the parse_tree package.
compiler/hlds_pred.m:
compiler/prog_data.m:
Remove the stuff now in status.m.
compiler/error_util.m:
Provide a mechanism to control the order of messages with respect to
ALL other messages, not just those that also specify ordering.
compiler/mercury_to_mercury.m:
Provide predicates for printing out parse_tree_* and *_compilation_unit,
since printing out a simple item list is no longer enough for debugging.
Pretty-print type definitions nicely.
Replace a boolean with a purpose-specific enum.
compiler/modules.m:
Rewrite virtually all this module to make it work on the new AST
representations. Generate more detailed error messages for duplicate
module inclusions. Note lots of possibilities for further improvements,
including in the documentation. Mark places I am still not sure about,
especially places where I am not sure *why* the code is doing
what it is doing.
compiler/module_imports.m:
This module stores the data structure in which we accumulate the stuff
imported into a compilation unit, i.e. it is in these data structures
that a raw_compilation_unit becomes an aug_compilation_unit. Modify
the data structure and the predicates that operate on it to work on the
new AST representations, not on an (apparently) simple list of items.
Avoid ambiguities by adding a prefix to field names.
Add some convenience predicates.
compiler/module_qual.m:
Perform module qualification on both raw lists of items (for use when
generating .int3 files) but also on item blocks (for use pretty much
in every other situation).
Generate warnings about module imports that are unnecessarily in the
module interface using the module's context (the context of the `:- module'
declaration), not line 1 of the relevant file.
compiler/prog_io_error.m:
Split some error categories more finely, since some error kinds here
actually used to be reported for more than one distinct situation.
compiler/prog_io_util.m:
Provide utility predicates that operate on nonempty lists.
compiler/recompilation.version.m:
Make the comparison of the old and new contents of the interface file
work on two parse_tree_ints, not on two raw sequences of items.
Delete a boolean option that was always `yes', never 'no'.
compiler/recompilation.m:
Turn some functions into predicates to allow the use of state variable
notation.
Avoid ambiguities by adding a prefix to field names.
compiler/write_module_interface_files.m:
Besides updating the code in this module to work on the new parse tree
representations, also use cords instead of reversed lists in several cases.
Note many possibilities for further improvements.
library/list.m:
Move the type one_or_more here from the compiler directory, since
we now use it in more than one compiler module, and this is its natural
home.
mdbcomp/sym_name.m:
Rename "match_sym_name" to "partial_sym_name_matches_full", since this
better describes its job.
Add a det version of sym_name_get_module_name.

Rename some types to make them more expressive.

Update the expected outputs in the invalid and warnings directories
to account for one or more of the following five changes.
Error messages that warn about a module not exporting anything
used to always refer to line 1 of the module's source file.
Now expect these messages to refer to the actual context of the module,
which is the context of its `:- module' declaration.
Expect a similarly updated context for messages that warn about
unnecessarily importing modules in the interface, not in the
implementation.
Expect a similarly updated context for messages that warn about
importing a module via both `:- import_module' and `:- use_module'.
For the modules that follow the `:- module' declaration directly with code,
also expect an error message about the missing section marker.
For modules that have terms after the `:- end_module' declaration,
replace "end_module" with "`:- end_module'" in the error message.
tests/invalid/func_class.{m,err_exp}:
New test case. It is a copy of the old tests/valid/func_class.m, which
is missing more than one module marker. The expected output is what I think
we should generate. The test case currently fails, because we currently
print only a subset of the expected errors. I am pretty sure the reason
for that is that old code I have not modified simply throws away the
missing error messages. Fixing this is work for the near future.

Quote cons_ids consistently in error messages.
compiler/error_util.m:
Add a format piece for identifying cons_ids.
compiler/hlds_out_util.m:
compiler/prog_out.m:
Add a version of the predicate that convert cons_ids to string
that quotes appropriately for error messages.
Move this predicate, and some existing predicates for converting
cons_ids to strings from hlds_out_util.m to prog_out.m, so that
error_util.m, which is part of the parse_tree.m package, can use them.
Since cons_ids are defined in prog_data, a part of parse_tree, they
should always have been here.
Make the same move for some other predicates that also convert to strings
values of other types defined in prog_data.m.

Improve the wording of some error messages.
Use the word "corresponding" instead of "preceding" in error messages like:
Error: clause for predicate `foo'/0 without preceding `:- pred'
declaration.
The language imposes no ordering on declarations so there is no sense in which
the `:- pred' declaration has to precede the clause. This is doubly true for
`:- typeclass' and `:- instance' declarations, which may also occur in
different source files from each other.

Further consistency improvements for error and warning messages.
The two main changes in this commit are: (1) Use the error_util library's decl/1 and pramga_decl/1 format components in more places. (2) Quote type variables that appear in error messages. compiler/error_util.m: Add a version of list_to_pieces/1 that places each of the strings in the input list in single quotes. compiler/prog_io_type_defn.m: Quote type variables names in error messages. compiler/add_class.m: compiler/add_pragma.m: compiler/add_pred.m: compiler/check_typeclass.m: compiler/make_hlds_error.m: compiler/post_typecheck.m: compiler/prog_io.m: Use the error_util library's decl/1 and pragma_decl/1 format components in more places. compiler/mode_errors.m: Quote program variables and insts in some error messages. compiler/post_term_analysis.m: Format a type ctor and arity in an error message properly. tests/invalid/*.err_exp: tests/warnings/*.exp: Conform to the above changes. |
