tests/invalid/invalid_int.m:
tests/invalid/invalid_int.err_exp2:
Extend this test case to cover the fixed size integer types.
Many predicates that do their jobs via foreign_procs in C have a fallback
Mercury clause for non-C backends, which usually throws an exception.
When compiled in non-C grades, these often get a warning that their
determinism declaration could have been tigther, e.g. erroneous instead of det.
*.m:
Add no_determinism_warnings pragmas before such fallback clauses.
library/dir.m:
As above, but also remove the unnecessary "dir." prefix on many predicate
declarations and clause heads.
Add the new builtin types: int8, uint8, int16, uint16, int32 and uint32.
Support for these new types will need to be bootstrapped over several changes.
This is the first such change and does the following:
- Extends the compiler to recognise 'int8', 'uint8', 'int16', 'uint16', 'int32'
and 'uint32' as builtin types.
- Extends the set of builtin arithmetic, bitwise and relational operators to
cover the new types.
- Extends all of the code generators to handle new types. There currently lots
of limitations and placeholders marked by 'XXX FIXED SIZE INT'. These will
be lifted in later changes.
- Extends the runtimes to support the new types.
- Adds new modules to the standard library intended to hold the basic
operations on the new types. (These are currently empty and not documented.)
This change does not introduce the two 64-bit types, 'int64' and 'uint64'.
Their implementation is more complicated and is best left to a separate change.

Add a new builtin type: uint, which is an unsigned word sized integer type.
Support for this new type will need be bootstrapped over several changes.
This is the first such change and does the following:
- Extends the compiler to recognize 'uint' as a builtin type.
- Extends the set of builtin operations to include relational and (some)
arithmetic operations on uints.
- Extends all of the code generators to handle the above. There are some
limitations currently marked by 'XXX UINT'. These will be lifted once
the compiler recognised uint and additional library support becomes
available.
- Extends the runtime to support uints.
compiler/prog_type.m:

These allow types to be defined in the following manner:
:- type job ---> job(pred(int::out, io::di, io::uo) is det).
For any construction unification using this functor the argument must
have the required higher-order inst; it is a mode error if it does not.
When terms of type job with inst ground are deconstructed, the argument
is inferred to have the given inst, allowing a higher-order call in that
mode.
The new type syntax is currently only permitted as the direct argument of
a functor in a du type definition. In future it would be meaningful to
support this syntax in other locations, but that is left for a separate
change.
In order to correctly implement the construct/3 library predicate, we
need to be able to dynamically check that arguments do not violate
any constraints on the argument insts. At the moment, we conservatively
abort if any such constraints are present irrespective of whether they
are satisfied or not. Since these constraints are a new feature, no
existing code will abort in this way.
The implementation refers to the inst information associated with types
as "subtype information". This is because, generally, we think of the
combination of a type with a fully bound inst (i.e., one that describes
terms that contain no unbound variables) describes a subtype of that type.

Start a C# backend, adapted from mlds_to_java.m.
Some `pragma foreign_*' declarations are commented out in this change because
no bootstrap compiler will yet accept "C#" in the language specification.
The compiler already supported C# foreign_procs for the IL backend, but the IL
backend and this new backend do not agree on naming and calling conventions so
the changes to the existing C# foreign_procs will further break the IL backend.
Nobody cares.
Only tested so far with Mono on Linux.

New module. In the CVS Attic there exists an obsolete file named
mlds_to_csharp.m (replaced by mlds_to_managed.m) which we don't want to

Allow inlining of Java foreign_procs.
This revealed a problem with directly using the `succeeded' flag directly as
the success indicator in Java foreign_procs. When the code of the foreign_proc
becomes a nested function, and after nested functions are eliminated, there may
not be a variable called `succeeded' in that context; it is moved into
environment struct, and the transformation is not able to update handwritten
code to reflect that. The solution is to declare a local variable for the
foreign_proc, let the handwritten code assign that, then assign its final
value to the `succeeded' flag with an MLDS statement.
We take the opportunity to name the local variable `SUCCESS_INDICATOR', in
line with other backends.

Expose correct types to Java foreign code, e.g. a variable with a non-foreign
type like `list(T)' is now visible to Java foreign code with the type
`list.List_1' instead of `java.lang.Object'.
A complication is that foreign code for mutables is generated in the compiler
frontend, which doesn't know about the types used by the backends. For Java,
mutable variables had the generic type `Object' (except for primitives types)
but as we now generate foreign procs with the correct variable types, the code
for accessing a mutable would be type incorrect, e.g.
X = mutable_var; /* list.List_1 = Object */
Here we handle generated mutable predicates as a special case, using `Object'
for the global variable and argument types and generating typecasts as before.
The correct fix would be to move mutable code generation into the backends.
compiler/make_hlds_passes.m:
Make Java mutable variables always have the type `java.lang.Object'.
Mark Java mutable predicates with `may_not_duplicate' attributes, as
the generated code doesn't contain class-qualifiers for the mutable

Put all Mercury-generated Java classes into the package `jmercury' and
runtime classes into `jmercury.runtime'. The Mercury module hierarchy is
not reflected in the package name. We name sub-module classes using
their fully-qualified module names with `__' between components, e.g.
`bit_buffer.read' produces `class bit_buffer__read'.
As all generated Java code is in the same package we don't need to package
qualify identifiers, and we don't need the hack to avoid clashing package
and class names. It also makes it easier to write Java foreign code because
generated Java class names are easier to predict from Mercury module names.
The package names are not `mercury' and `mercury.runtime' because on
case-insensitive file systems we may end up with a `mercury' directory
that could be confused with the `Mercury' directory.

Add a new compiler option. --inform-ite-instead-of-switch. If this is enabled,
the compiler will generate informational messages about if-then-elses that
it thinks should be converted to switches for the sake of program reliability.

nontrivial downsides. This typically happens with the switched-on type
has many functors, and we treat one or two specially (e.g. cons/2 in

Add support for foreign enumerations to Mercury. These allow the
programmer to assign foreign language values as the representation of
enumeration constructors.
e.g.
:- type status
---> optimal
; infeasible
; unbounded
; unknown.
:- pragma foreign_enum("C", status/0, [
optimal - "STATUS_OPTIMAL",
infeasible - "STATUS_INFEASIBLE",
unbounded - "STATUS_UNBOUNDED",
unknown - "STATUS_UNKNOWN"
]).
The advantage of this is that when values of type status/0 are passed to
foreign code (C in this case) no translation is necessary. This should
simplify the task of writing bindings to foreign language libraries.
Unification and comparison for foreign enumerations are the usual
unification and comparison for enumeration types, except that the default
ordering on them is determined by the foreign representation of the
constructors. User-defined equality and comparison also work for foreign
enumeration types.
In order to implement foreign enumerations we have to introduce two
new type_ctor representations. The existing ones for enum type do not
work since they use the value of an enumeration constructor to perform
table lookups in the RTTI data structures. For foreign enumerations
we need to perform a linear search at the corresponding points. This
means that some RTTI operations related to deconstruction are more
expensive.
The dummy type optimisation is not applied to foreign enumerations as
the code generators currently initialise the arguments of non-builtin
dummy type foreign_proc arguments to zero. For unit foreign enumerations
they should be initialised to the correct foreign value. (This is could be
implemented but in practice it's probably not going to be worth it.)
Currently, foreign enumerations are only supported by the C backends.
compiler/prog_io_pragma.m:
