tests/hard_coded/*.m:
Rename modules as mentioned above.
In a few cases, where the main module's name itself had a suffix,
such as "_mod_a" or "_main", remove that suffix. This entails
renaming the .exp file as well. (In some cases, this meant that
the name of a helper module was "taken over" by the main module
of the test case.)
Update all references to the moved modules.
General updates to programming style, such as
- replacing DCG notation with state var notation
- replacing (C->T;E) with (if C then T else E)
- moving pred/func declarations to just before their code
- replacing io.write/io.nl sequences with io.write_line
- replacing io.print/io.nl sequences with io.print_line
- fixing too-long lines
- fixing grammar errors in comments
tests/hard_coded/Mmakefile:
tests/hard_coded/Mercury.options:
Update all references to the moved modules.
Enable the constant_prop_int test case. The fact that it wasn't enabled
before is probably an accident. (When constant_prop_int.m was created,
the test case was added to a list in the Mmakefile, but that list
was later removed due to never being referenced.)
tests/hard_coded/constant_prop_int.{m,exp}:
Delete the calls to shift operations with negative shift amounts,
since we have added a compile-time error for these since the test
was originally created.
tests/hard_coded/*.m:
Update programming style, unless doing so would change
the meaning of the test, in particular:
- use '.' as a module qualifier in place of '__'
- use {write,print}_line where appropriate
- use if-then-else in place of C -> T ; E
- use state variables in place of DCGs
tests/hard_coded/dir_test.m:
Document what the expected outputs correspond to.
Use a uniform module qualifier in the output.
tests/hard_coded/dir_test.exp*:
Conform to the above change.

Make these tests use four-space indentation, and ensure that
each module is imported on its own line. (I intend to use the latter
to figure out which subdirectories' tests can be executed in parallel.)
These changes usually move code to different lines. For the debugger tests,
specify the new line numbers in .inp files and expect them in .exp files.

Type_desc__get_functor looks up the types of the arguments of a function
symbol. This predicate used to abort when an argument has an existential
type. This diff makes type_desc__get_functor work even in that case.
However, since in such cases the type of an argument is not a ground type,
this diff has to add the concept of a pseudo_type_desc, a descriptor for
a not necessarily ground type. Pseudo_type_descs are implemented as
MR_PseudoTypeInfos.
runtime/mercury_type_info.[ch]:
Add new macros to operate on pseudo_type_infos. Most have a structure
modelled on corresponding macros operating on type_infos.
Provide versions of MR_get_arg_type_info, MR_compare_type_info,
MR_unify_type_info, MR_collapse_equivalences,
MR_type_params_vector_to_list, MR_create_type_info and
MR_create_type_info_maybe_existq that work on pseudo_type_infos,
not type_infos.
Change MR_pseudo_type_info_vector_to_type_info_list, which implements
the core of get_functor, to return pseudo_type_infos instead of
type_infos, and rename it to reflect this fact.
Change to four-space indentation to reduce the number of lines
that have to be wrapped.
runtime/mercury_make_type_info_body.h:
Generalize the code for creating type_infos to also be handle
pseudo_type_infos.
Change to four-space indentation to reduce the number of lines
that have to be wrapped.
runtime/mercury_type_desc.[ch]:
Provide versions of MR_make_type_ctor_desc and MR_type_ctor_and_args
that work on pseudo_type_infos, not type_infos.
Change to four-space indentation to reduce the number of lines
that have to be wrapped.
runtime/mercury_builtin_types.[ch]:
runtime/mercury_builtin_types_proc_layouts.h:
runtime/mercury_hlc_types.h:
runtime/mercury_unify_compare_body.h:
Add the C types, global variables and functions necessary for the
new builtin Mercury type pseudo_type_desc. This type must be builtin,
because its structure (MR_PseudoTypeInfo) is defined in C, and as such
cannot be unified, compared, deconstructed etc without hand-written
C code.
runtime/mercury_deep_copy.c:
runtime/mercury_deep_copy_body.h:
Handle the copying of pseudo_type_infos/pseudo_type_descs. This code
is almost the same as the code to copy type_infos, but must of course
handle type variables, and the arguments are themselves copied as
pseudo_type_infos, not type_infos.
runtime/mercury_types.h:
Since deep copy needs to create pseudo_type_infos, provide a version
of the MR_PseudoTypeInfo type without const.
runtime/mercury_construct.c:
runtime/mercury_deconstruct.c:
Handle pseudo_type_descs just as we handle type_descs: neither can be
constructed, nor do they have function symbols with named arguments.
runtime/mercury_ml_expand_body.c:
Provide code to deconstruct pseudo_type_descs. This code is almost
the same as the code to deconstruct type_descs, but must of course
handle type variables, and the arguments are themselves
pseudo_type_descs, not type_descs.
runtime/mercury_tabling.c:
Catch attempts to table pseudo_type_infos.
runtime/mercury_tags.h:
Add macros for constructing lists of
pseudo_type_infos/pseudo_type_descs.
runtime/mercury_wrapper.[ch]:
Define global variables holding the addresses of the typeinfos for
describing pseudo_type_descs and lists of pseudo_type_descs.
runtime/mercury_init.c:
Add the extern declarations required by new code in mkinit.c.
util/mkinit.c:
Make the addresses of the typeinfos for describing pseudo_type_descs
and lists of pseudo_type_descs, defined in the library, known to the
runtime.
library/type_desc.m:
Add a new builtin type, pseudo_type_desc, for describing possibly
nonground types.
Add utility predicates for operating on pseudo_type_descs.
library/private_builtin.m:
Handle the new builtin type.
Add builtin typeinfos for describing pseudo_type_descs and lists of
pseudo_type_descs, since some functions in the runtime need them
for memory profiling.
library/rtti_implementation.m:
Handle the new builtin type, mostly by ignoring it, since the backends
that use this module do not have any notion of pseudo_type_infos.
Bring the module up to date with our formatting guidelines.
library/construct.m:
Make get_functor return a list of pseudo_type_descs instead of
type_descs.
Change the name of the version of get_functor that returns argument
names, to distinguish it from the base version by more than just the
arity.
Make the order of predicates more logical.
library/std_util.m:
Change the name of the version of get_functor that returns argument
names, to distinguish it from the base version by more than just the
arity.
However, this name change is effectively the only change: both
get_functor and get_functor_with_names still return lists of
type_descs. This means that they will throw exceptions in the presence
of existential types, but code using them need no algorithmic changes.
library/term.m:
library/term_to_xml.m:
Add module qualifiers as necessary; no algorithmic changes.
library/list.m:
Add two general-purpose predicates, all_true and all_false,
for use in the other library modules.
compiler/ml_util.m:
compiler/mlds_to_gcc.m:
compiler/rtti.m:
compiler/type_ctor_info.m:
Make sure we handle the new builtin type as a builtin type, and not
try to have the compiler create a type_ctor_info for it.
deep_profiler/canonical.m:
Delete the local definition of all_true.
tests/hard_coded/construct_test.{m,exp}:
Update this test case to test the ability to retrieve the names of the
fields of function symbols with existential types.
Add module qualifications as necessary.
tests/hard_coded/construct_test_exist.{m,exp}:
Add a tougher test case to print the types of the arguments of
function symbols with existential types.
tests/hard_coded/Mmakefile:
Add the new test case, and sort the names of the tests.
