Ralph Becket <rwab1@cam.sri.com>'s changes to add functions for
the remaining output det predicates in a number of modules in the
standard library. Basically, for each
:- pred f(in, ..., in, out) is det.
he has added the declaration
:- func f(in, ..., in) = out.
and definition
f(X1, ..., Xn) = Y :-
f(X1, ..., Xn, Y).
The changes were made using a mostly automatic process.

library/*.m:
compiler/*.m:
Undo Zoltan's bogus update of all the copyright dates.
The dates in the copyright header should reflect the years
in which the file was modified (and no, changes to the
copyright header itself don't count as modifications).

Enable --warn-interface-imports by default. This was turned off while
list and term were defined in mercury_builtin.m, since it caused many
warnings.
Fix all the unused interface imports that have been added since then.
compiler/options.m:
Enable --warn-interface-imports by default.
compiler/module_qual.m:
Fix formatting inconsistencies with module names in warning
messages. (".m" was not appended to module names if there was
only one module).
compiler/*.m:
library/*.m:
tests/invalid/type_loop.m:
tests/warnings/*.m:
Remove usused interface imports, or move them into
implementation (mostly bool, list and std_util).
library/*.m:
Improve the documentation.
Add a "Stability: low/medium/high" comment to all modules,
which describes the stability of the interface to that module.
ops.m:
Add `:' as an infix operator.
require.m:
Implement require/1, since higher-order predicates now work.
term.m:
Use the type `comparison_result' from mercury_builtin.m,
rather than defining an identical type `comparison'.
list:
added a list__chunk primitive.
std_util:
added bool__or_list, bool__and_list, and bool__not.
others:
suppressed determinism warnings by changing declarations from nondet to
multidet and with judicious use of semidet_fail and semidet_succeed.
Makefile.mercury:
Override the MERCURY_LIB_OBJS variable when invoking ml.
This avoids some bootstrapping problems.
Also, add mercury_compile.nu.
Makefile.common:
Bump NU-Prolog's -u option up to 2000 (8M), to avoid some memory
problems.
array.nl, bintree.nl, char.nl, dir.nl, globals.nl, list.nl, map.nl, modes.nl,
prog_util.nl, stack.nl, std_util.nl, string.nl, term.nl:
Avoid the use of implied modes.
code_info.nl, bimap.nl, make_hlds.nl, mercury_compile.nl,
mercury_to_mercury.nl, unify_proc.nl:
Fix determinism errors which had previously not been discovered
because of either implied modes or running out of memory.
(Note that I had to change the interface to bimap__lookup, since
it's not possible to make it bidirectional.)
code_util.nl, llds.nl, opt_debug.nl, value_number.nl:
Rename `operator' as `binary_op'.
hlds.nl, code_info.nl, unify_gen.nl, llds.nl, opt_debug.nl, switch_gen.nl:
*** Handle simple cases of higher-order pred terms. ***
(We don't yet handle taking the address of an overloaded
predicate or a predicate with multiple modes.
We don't handle closures. call/1 and call/N are not yet implemented.
This has not yet been tested.)
make_hlds.nl:
Modify the mode priority ordering so that semidet modes get
selected before det ones.
llds.nl:
Don't include the priority part of the mode number in the mangled
label name. *** Note: this will break some things! ***
mercury_compile.nl:
Move the NU-Prolog hacks into mercury_compile.nu.nl.
switch_gen.nl:
Fix a simple logic bug in handling the grab/slap of the code_info.
prog_io.nl, builtins.nl, int.nl:
Fix bugs and omissions with handling of the new arithmetic operators.
prog_io.nl:
As a quick hack, strip off calls to io__gc_call
(this avoids spurious error messages which are due to
the fact that we don't get mode analysis right in those cases).
code_gen.nl, code_info.nl, disj_gen.nl, ite_gen.nl, switch_gen.nl:
Various bug fixes for non-deterministic code.
(nqueens now works! ;-)
live_vars.nl:
Bug fix: initial liveness should be {input vars} not {output vars}.
(Apologies from Thomas ;-).
llds.nl:
Couple of minor bug fixes. Added code to output redo().
io.nl, portray.nl, prog_io.nl, std_util.nu.nl, term_io.nu.nl:
Change X.Xs into [X|Xs].
swi_builtin.nl, doit.pl:
Add some support for SWI-Prolog.
set.nl, stack.nl:
Suppress bogus SWI-Prolog singleton variables warnings in
type declarations.
term_io.nu.nl:
Remove some of the dependences on NU-Prologisms.
hlds.nl, hlds_out.nl, det_analysis.nl:
Remove the unused `declared_determinsm' field in the goal_info.
Rename the `inferred_determinism' field as just `determism'.
Add a new field `local_determinism'. In det_analysis.nl,
Plug the contents of the new `local_determinsm' field in the goal_info
into the computation of the determinism for each goal.
det_analysis.nl, fix_errs.sed:
For the cases which we currently don't handle correctly,
generate incorrect code in preference to generating spurious
error messages (we still have to handle these cases sometime,
but this means that we can deal with them one at a time).
arg_info.nl, builtins.nl, code_gen.nl, delay_info.nl, det_analysis.nl,
getopt.nl, globals.nl, make_hlds.nl, modes.nl, mode_util.nl, stack.nl,
string.nl, string.nu.nl, term.nl, undef_modes.nl, varset.nl:
Fix determinism errors uncovered by the changes in the determinism
analysis.
