Makefile:
added entries for the new files.
codegen.nl:
This is really a new file (well almost). Contains the top level
of the code generator.
doit.nl:
Added the new files (and mode_error which was missing).
hlds.nl:
Changed the type declaration for unifications to use arg_mode
instead of mode.
hlds_out.nl:
Small change for the above alteration.
llds.nl:
Minor changes.
mode_util.nl:
Change the modes to arg_modes for unifications.
modes.nl:
ditto.
std_util.nl:
more assoc_list predicates...
term.nl:
Fixed a small but nasty by in term__vars_list (and don't forget
Fergus that you owe me a chocolate biscuit).
prog_io.nl, hlds.nl:
Add `arity' as an alias for `int'.
map.nl:
Improve the code for map__merge.
Add map__optimize.
Work-around a bug in the determinism analysis.
make_hlds.nl:
Use map__optimize rather than bintree__balance.
codegen.nl, std_util.nl:
Add a call to `semidet_succeed' in codegen.nl, and
implement that pred in std_util.nl, in an
attempt to suppress a determinism warning.
(The attempt failed, due to an as-yet unknown bug in
the determinism analysis.)
hlds.nl, modes.nl, mode_util.nl, mercury_to_mercury.nl, undef_modes.nl.
Replace the inst table with four tables, one for
user-defined insts, and three for compiler-generated
insts. Modify all the routines dealing with insts to
handle this. Change `inst_merge' in modes.nl to return
a compiler-generated recursive inst if necessary.
term_io.nl:
Fix bugs caused by recent changes to io__xxx_op preds.
Makefile, apply_sed_script, fix_errs.sed:
A quick hack to avoid the spurious determinism errors.
term_io.nl, char.nl, string.nl:
Add a few additional utility preds to string.nl.
Add some more preds to handle quoting to term_io.nl.
Remove the stuff which handled quoting in char.nl.
bintree.nl, map.nl, std_util.nl:
Use assoc_list/2 rather than list(pair(...)).
hlds.nl, det_analysis.nl:
Make instmap delta an association list rather than a map;
fix the determinism analysis to use that.
Makefile, doit.nl:
Add det_analysis.nl and builtins.nl.
builins.nl:
Fix bug.
codegen.nl:
Make unimplemented cases abort rather than just fail.
modes.nl, typecheck.nl:
Fix bugs introduced by the performance fixes.
(I wonder if the performance problem will come back now? ;-)
options.nl, toplevel.nl:
Add a new pred `maybe_flush_output' and use it in toplevel.nl.
mercury_to_mercury.nl:
New file: converts the prog_io data structure back into Mercury source
code.
term_io.nl:
Export mercury_quote_string for use by mercury_to_mercury.nl.
Makefile, doit.nl:
Add mercury_to_mercury.
options.nl, toplevel.nl:
Add a new option to save the interface of a module to a `.int' file,
using mercury_to_mercury.
Makefile:
Modify the rule for the `clean' target so that it removes `.int' files.
mercury_builtin.nl:
Fix the module name.
std_util.nl:
Suppress warnings from nit.
modes.nl:
New file. At the moment it just checks for undefined modes and
undefined insts.
Makefile, doit.nl:
Add new files modes.nl and prog_util.nl.
term.nl:
Add term__var_to_int.
toplevel.nl:
Call the mode checker.
prog_io.nl, make_hlds.nl, hlds.nl:
Allow for the possibility of abstract `inst' definitions,
just like abstract type definitions. Currently they
are allowed for in the data structure, but they aren't
parsed correctly, and the utilities in hlds.nl don't handle
them that well.
hlds.nl:
Move `unqualify_name' to prog_util.nl.
make_hlds.nl:
Move `split_types_and_modes' to prog_util.nl.
mercury_to_goedel.nl, toplevel.nl:
Move the equivalence type expansion code to prog_util.nl.
builtin.nl, toplevel.nl:
Add a new module `builtin.nl' which gets automatically imported
into every module. In it, define the standard modes input,
output, etc., and various other stuff.
std_util.nl:
Move the defintion for \= to builtin.nl.
Remove the definition of ~=.
prog_io.nl:
Export parse_goal/2, since it's used by mercury_to_goedel.
mercury_to_goedel.nl:
Fix various type errors.
list.nl, int.nl, io.nl, codegen.nl, det_analysis.nl, llds.nl, hlds_out.nl:
Fix various syntax errors, typos and errors in type and mode
declarations discovered by mercury_compile.
typecheck.nl:
fix bug in error message code
Makefile:
remove pathname from NC definition
make_hlds.nl:
initialize the unify_context field.
std_util.nl, std_util.nu.nl:
move the implementation of solutions/2 from std_util to std_util.nu
(where it should have been in the first place).
typecheck.nl:
added handling of higher-order predicates and the builtin types
pred, pred(T), pred(T1, T2), etc.
hlds.nl:
added new field pred_name_index to the moduleinfo data structure
(needed for higher-order pred handling in typecheck.nl).
make_hlds.nl:
update the pred_name_index
make_hlds.nl:
detect and report as an error any attempts to define multiple
constructors for a single type with the same name and arity.
Makefile:
minor fixes.
hlds_out.nl:
fix type errors introduce when pred_mode_id was renamed as proc_id.
mercury_to_goedel.nl:
fix problems causes by modifications to prog_io.nl.
various places:
change to use the new builtin higher-order pred types.
Optimize for the common case of non-polymorphic types & predicates.
term.nl: Rename term__apply_substitution as term__apply_rec_substitution
and add a new term__apply_substitution for when you want
non-recursive application. Fix logic bug in
term__substitute_corresponding.
varset.nl: Fix logic bug in varset__merge.
io.nu.nl: Fix typo in error message.
term_io.nu.nl: Fix bug in the code used to work-around the NU-Prolog
getToken bug for empty strings.
prog_io.nl: Fix bug: the string "\+" should have been "\\+".
Also fixed LOTS of type errors (discovered by the typechecker,
hurray it now works!).
int.nl, list.nl, std_util.nl: Added pred & mode declarations for some
NU-Prolog predicates that we are using.
Added a couple of new preds to std_util.nl and added std_util.nu.nl.
Fixed some bugs in the typechecker, and improved error reporting
a bit.
Did a bit of work on memory management.
prog_out.nl: remove various bits of crud and clean it up a little.
hlds.nl: add some stuff needed by typecheck.nl
typecheck.nl: did a bit more work on this.
renamed module.nl as toplevel.nl and also rewrote it using stuff
from mercury_to_goedel.nl.
