This file-specific setting will override a default setting of expandtabs
in $HOME/.vimrc.
*/Makefile:
*/Mmakefile:
As above.
tests/hard_coded/.gitignore:
Don't ignore the purity subdir. This ignore must have been left over
from when purity.m was a test in hard_coded, not hard_coded/purity,
and it ignored an executable, not a directory.
Branches: main, 11.01
Fix up various problems in some of the samples that cause the compiler
to emit warnings.
samples/diff/Mmakefile:
Delete an old workaround for gcc 2.7.2 - we no longer support
gcc versions that old.
samples/diff/options.m:
samples/muz/muz.m:
samples/typecheck.m:
Avoid some Mercury compiler warnings.

Fix a performance bug where dead_pred_elim was taking a significant
amount of time to delete entries from the predicate_table. With this
change dead_pred_elim goes from 12 minutes to 55 seconds CPU time in
the IL grade when compiling accumulator.m with
--intermodule-optimization turned on.
compiler/hlds_module.m:
Implement a new predicate, predicate_table_restrict, which
restricts the predicate_table to include only a subset of the
predicates.
Rather than deleting all the non-needed entries, this
predicate builds the predicate_table from scratch again, hence
this predicate is only useful when the number of predicates to
keep is significantly less than the number of predicates to
delete.
Change predicate_table_do_insert so that it records in the
pred_info whether or not a predicate can only be accessed by
its fully qualified name, this is needed so that the
predicate_table can be rebuilt correctly.
compiler/dead_proc_elim.m:
Use predicate_table_restrict to restrict the set of pred_ids
in the predicate_table rather than module_info_remove_predicate
as the amount of predicates to keep is in general
significantly smaller than the number of predicates to keep.
compiler/hlds_pred.m:
Add a new pred_marker which indicates whether or not a
predicate can only be accessed by its fully qualified name.
compiler/hlds_out.m:
compiler/intermod.m:
Handle the new pred_marker.
Estimated hours taken: 0.25
samples/diff/Mmakefile:
Fix a bug: it was passing `-O0' in MGNUCFLAGS, rather than CFLAGS.
This broke things if you tried to pass an mgnuc option such as
`--inline-alloc' in EXTRA_MGNUCFLAGS on the command-line.

Modified files
--------------
samples/diff/Mmakefile:
Minor documentation update.
samples/diff/README:
samples/diff/TODO:
Update stuff that's now done, do a couple of minor wording
changes.
samples/diff/diff.m:
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.
samples/diff/filter.m:
Minor syntax/wording changes.
samples/diff/options.m:
Update all the newly handled options.
New files
---------
samples/diff/myers.m:
New diff algorithm.
samples/diff/match.m:
New pass to match common lines in the files to be diffed.
Removed file
------------
samples/diff/lcss.m:
Functionality replaced by myers.m.
Estimated hours taken: 30
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.
Removed files
-------------
samples/diff/diffs.m:
Functionality moved to diff_out.m.
samples/diff/lcsstype.m:
Functionality moved to difftype.m.
Estimated hours taken: 4
General cleanup and bug fix for diff. Features of this diff:
- Changed indenting so it more closely matches the
coding standard.
- Bug fix which was causing it to bomb out if the two
files were identical.
- Update to use unique arrays (array.m).
samples/diff/README:
Added something which resembles this log message.
samples/diff/Mmakefile:
Turned C optimisation off to get around a gcc 2.7.2 bug.
samples/diff/diff.m:
samples/diff/diffs.m:
samples/diff/file.m:
samples/diff/lcss.m:
samples/diff/lcsstype.m:
Changes detailed above.
Estimated hours taken: 0.5
Rename all the `Mmake' files as `Mmakefile'. This is necessary to
avoid confusion between `Mmake' and `mmake' on case-insensitive file
systems.
