User-guided type specialization.
compiler/prog_data.m:
compiler/prog_io_pragma.m:
compiler/modules.m:
compiler/module_qual.m:
compiler/mercury_to_mercury.m:
Handle `:- pragma type_spec'.
compiler/prog_io_pragma.m:
Factor out some common code to parse predicate names with arguments.
compiler/hlds_module.m:
Added a field to the module_sub_info to hold information about
user-requested type specializations, filled in by make_hlds.m
and not used by anything after higher_order.m.
compiler/make_hlds.m:
For each `:- pragma type_spec' declaration, introduce a new predicate
which just calls the predicate to be specialized with the
specified argument types. This forces higher_order.m to produce
the specialized versions.
compiler/higher_order.m:
Process the user-requested type specializations first to ensure
that they get the correct names.
Allow partial matches against user-specified versions, e.g.
map__lookup(map(int, list(int)), int, list(int)) matches
map__lookup(map(int, V), int, V).
Perform specialization where a typeclass constraint matches a
known instance, but the construction of the typeclass_info is
done in the calling module.
Give slightly more informative progress messages.
compiler/dead_proc_elim.m:
Remove specializations for dead procedures.
compiler/prog_io_util.m:
Change the definition of the `maybe1' and `maybe_functor' types
to avoid the need for copying to convert between `maybe1'
and `maybe1(generic)'.
Changed the interface of `make_pred_name_with_context' to allow
creation of predicate names for type specializations which describe
the type substitution.
compiler/make_hlds.m:
compiler/prog_io_pragma.m:
Make the specification of pragma declarations in error
messages consistent. (There are probably some more to
be fixed elsewhere for termination and tabling).
compiler/intermod.m:
Write type specialization pragmas for predicates declared
in `.opt' files.
compiler/mercury_to_mercury.m:
Export `mercury_output_item' for use by intermod.m.
compiler/options.m:
Add an option `--user-guided-type-specialization' enabled
with `-O2' or higher.
compiler/handle_options.m:
`--type-specialization' implies `--user-guided-type-specialization'.
compiler/hlds_goal.m:
Add predicates to construct constants. These are duplicated
in several other places, I'll fix that as a separate change.
compiler/type_util.m:
Added functions `int_type/0', `string_type/0', `float_type/0'
and `char_type/0' which return the builtin types.
These are duplicated in several other places,
I'll fix that as a separate change.
library/private_builtin.m:
Added `instance_constraint_from_typeclass_info/3' to extract
the typeclass_infos for a constraint on an instance declaration.
This is useful for specializing class method calls.
Added `thread_safe' to various `:- pragma c_code's.
Added `:- pragma inline' declarations for `builtin_compare_*', which
are important for user-guided type specialization. (`builtin_unify_*'
are simple enough to go in the `.opt' files automatically).
compiler/polymorphism.m:
`instance_constraint_from_typeclass_info/3' does not need type_infos.
Add `instance_constraint_from_typeclass_info/3' to the
list of `typeclass_info_manipulator's which higher_order.m
can interpret.

samples/diff/TODO:
Update stuff that's now done, do a couple of minor wording
changes.

Fix case of identical filenames (which implicitly assumed
no_diff_implies_no_output). Add new match pass, call the
new diff algorithm.
samples/diff/diff_out.m:
Add --cvs-merge-conflict output style. Slight reorganisation
of top-level predicate. Lots of small fixes to use better
syntax (e.g. functional style for integer maths operations).
samples/diff/difftype.m:
Added first_mentioned_positions/3, last_mentioned_positions/3,
add_edit/4.
samples/diff/file.m:
Use io__read_line_as_string.

Also sneaked in here are some trivial whitespace fixes in some
of the pragma c_code which did not comply with our coding
standards (to do with type casting).

Modified files
--------------
samples/diff/README:
Info about this new version. Put the existing READMEs in
reverse order, so that they'll be in the most sensible order
for someone reading top-down.
samples/diff/Mmakefile:
Supply more detail about which bit of this program GCC 2.7.2
under Digital Unix 3.2 doesn't compile properly.
samples/diff/diff.m:
Slight reorganisation. Accept options, remove some high
coupling betweem diff__do_diff and lcss.m.
samples/diff/file.m:
Add support for attaching a filename to a file.
samples/diff/lcss.m:
Add more documentation, one slight performance improvement.
lcss__to_diff now works on the reversed LCSS, to avoid going
to the trouble of reversing it.
New files
---------
samples/diff/TODO:
Meaning should be obvious.
samples/diff/diff_out.m:
Replacement for diffs.m (which was never a very good name).
Now contains code to display a diff in lots more output
styles than previously supported.
samples/diff/difftype.m:
Replacement for lcsstype.m. Contains the type of a diff (but
not of an lcss, which is now local to lcss.m, hence the
renaming).
samples/diff/filter.m:
Contains code to filter a diff before being displayed. This
is only required if the user specified that they didn't want
to see part of the diff (e.g. with --ignore-blank-lines).
samples/diff/globals.m:
samples/diff/options.m:
Support for option handling.

samples/diff:
Committed the changes sent by Marnix Klooster <marnix@worldonline.nl>.
His description of the changes:
The major changes I made were
* Moved code for manipulating and displaying diffs to a separate
module called diffs.m (and changed their calls in diff.m). The type
'lcss,' needed both by the rest of lcss.m and by diffs.m, was moved
to a new module lcsstype.m.
* Made lcss.m independent of files, and allowed it to process any kind
of list by adding polymorphism. (The file processing calls have
been moved to diff.m.)
* Added type synonyms 'pos' and 'segment' in diffs.m to clarify the
types. Renamed 'single_diff' to 'edit'.
* Added end-of-file match to the generated lcss, thereby allowing the
to_diff predicate to be simplified considerably.
* Numbered lists from 0 internally in the lcss-algorithm. This made
to_diff simpler still, but also forced changes in the diff-printing
part.
* Removed the swapping in find_lcss, because it doesn't seem to help.
* The array(string) representing a file in file.m was also renumbered
to begin with 0.
* Added and corrected comments.
Have fun,
