As above.
compiler/Mercury.options:
Specify --warn-impliciy-stream-calls for all the modules above.
compiler/file_util.m:
Delete a utility predicate that expects its clients to operate on
implicit streams, since the changes above replaced the last calls to it
with the variant that expects its client to operate on explicit streams.
compiler/mlds_to_cs_data.m:
compiler/mlds_to_java_data.m:
Generate C# and Java code for initializers that shows its structure
by its indentation. To make this possible, make the affected predicates
take arguments that say what to put after the initializer(s).
Document what these predicates do in terms of indentation as well as
in terms of the code they are writing out.
Put a space after cast operators.

compiler/mlds_to_java_stmt.m:
Use the new mechanisms in mlds_to_{cs,java}_data.m to generate code
that shows its structure by indentation.
Fix bad line breaks when writing out lists of arguments.
When all call sites to a predicate specify the same value of an argument,
and no other value makes sense for that argument, then delete the argument
after "inlining" its value.
Delete obsolete comments.
compiler/mlds_to_target_util.m:
Add a utility predicate and a type needed by new code in the files above.
Step 1 is making it a builtin; step 2 will be declaring it.
(We won't define it, since builtins may not have definitions.)
compiler/builtin_ops.m:
Make unsigned_lt a builtin operation, and recognize
private_builtin.unsigned_lt which does not exist yet,
as that operation.
We already had a builtin operation unsigned_le, which the compiler
generated references to internally. Recognize private_builtin.unsigned_le
as this builtin operation. The difference is that just having a builtin op
is enough for compiler passes inside the LLDS/MLDS/ELDS backends
that generate LLDS/MLDS/ELDS code that refer to the builtin op,
(though the ELDS backend does not have any code that does such things),
while code that wants to create references to builtin ops in the HLDS
needs to have access to the predicate declaration of each builtin.
So far, we intend to use only unsigned_lt, not unsigned_le, in this manner,
but treating two such closely related ops differently would violate
the law of least astonishment.
Fix an old XXX that is related to this diff only in affecting the same
type: standardize on add/sub/mil/div terminology over
plus/minus/times/divide terminology.
compiler/erl_call_gen.m:
Abort on references to unsigned_lt as well as unsigned_le.
compiler/llds_out_data.m:
compiler/ml_global_data.m:
compiler/mlds_to_c_data.m:
The C backends already implemented unsigned_le. Handle unsigned_lt
the same way as unsigned_le, only with s/<=/</.
compiler/mlds_to_cs_data.m:
Implement both unsigned_lt and unsigned_le, using the C# foreign_proc
implementation of unsigned_lt in library/int.m as a basis.
compiler/mlds_to_java_data.m:
Implement both unsigned_lt and unsigned_le, using the Java foreign_proc
implementation of unsigned_lt in library/int.m as a basis.
compiler/options.m:
Provide a way to detect whether the installed compiler has this diff.
We will need such a test in configure.ac for stage 2.
compiler/bytecode.m:
compiler/llds.m:
compiler/mlds_dump.m:
compiler/opt_debug.m:
Conform to the changes above.
library/int.m:
Module qualify references to unsigned_lt. This is to allow the
affected code to compile even after the declaration of unsigned_lt
as a predicate in private_builtin.m. (The last step of this sequence
would be the deletion of both int.unsigned_lt and the references to it.)
compiler/builtin_ops.m:
Parameterize the unchecked left and right shift builtin ops
by whether the shift amount is an int or an uint. So far,
the shift amount has always been an int; allowing the shift amount
to be a uint is new.
Recognize the Mercury functions unchecked_{left,right}_ushift
as being builtins implemented by the new variants of the unchecked
shift builtin ops mentioned above. These Mercury functions do not
exist yet. They will be added in step two of this diff, *after* this
change has been installed. (Making something a builtin, and *then*
defining it, is easier than defining it, and *then* making it a builtin,
because in the latter case, the stage 1 and stage 2 compilers disagree
on whether the function in question needs to have a definition.)
compiler/options.m:
Provide a way to check whether an installed compiler has this diff.
(This is needed for step 2.)
compiler/lookup_switch.m:
compiler/ml_lookup_switch.m:
compiler/ml_unify_gen_util.m:
compiler/unify_gen_util.m:
When generating references to unchecked shift ops, specify that the
shift amount is an int.
compiler/erl_call_gen.m:
Don't treat unchecked shifts by uint amounts as builtins, since I (zs)
don't know how this should be done in Erlang.
compiler/llds_out_data.m:
compiler/mlds_to_c_data.m:
compiler/mlds_to_cs_data.m:
When writing out unchecked shifts for C or C#, cast the shift amount
to int if it was originally uint.
compiler/mlds_to_java_data.m:
When writing out unchecked shifts for Java, ignore the type of the
shift amount, since (in the absence of a uint type in Java) we
represent both int and uint values the same way.
compiler/bytecode.m:
compiler/c_util.m:
compiler/llds.m:
compiler/ml_global_data.m:
compiler/mlds_dump.m:
compiler/opt_debug.m:
Conform to the changes above.
compiler/mlds_to_cs_data.m:
compiler/mlds_to_java_data.m:
Implement output_int_const_for_{csharp,java} without using
0xffffffff. When that constant appears in a C source file,
the C compiler may warn about it as it will not fit in a 32-bit
signed int.
compiler/mlds.m:
Make two changes to mlds_type.
The simpler change is the deletion of the maybe(foreign_type_assertions)
field from the MLDS representations of Mercury types. It was never used,
because Mercury types that are defined in a foreign language that is
acceptable for the current MLDS target platform are represented
as mlds_foreign_type, not as mercury_type.
The more involved change is to change the representation of builtin types.
Until now, we had separate function symbols in mlds_type to represent
ints, uints, floats and chars, but not strings or values of the sized
types {int,uint}{8,16,32,64}; those had to be represented as Mercury types.
This is an unnecessary inconsistency. It also had two allowed
representations for ints, uints, floats and chars, which meant that
some of the code handling those conceptual types had to be duplicated
to handle both representations.
This diff provides mlds_builtin_type_{int(_),float,string,char} function
symbols to represent every builtin type, and changes mercury_type
to mercury_nb_type to make clear that it is NOT to be used for builtins
(the nb is short for "not builtin").
compiler/ml_code_util.m:
compiler/ml_util.m:
Delete functions that used to construct MLDS representations of builtin
types. The new representation of those types is so simple that using
such functions is no less cumbersome than writing down the representations
directly.

compiler/mlds_to_java_data.m:
In output_int_const_for_csharp and output_int_const_for_java,
right shift by 31 instead of 32 to avoid shift count overflow
warnings from 32-bit compilers.
Simplify the code.
compiler/mlds_to_java.m:
Delete this module. Move its contents to the following eleven modules.
compiler/mlds_to_java_class.m:
Code to output class definitions.

Code to output lvals, rvals and initializers.

compiler/mlds_to_java_wrap.m:
Code to create wrapper classes, to help implement function pointers.
compiler/ml_backend.m:
Delete the old module, add the new modules.
compiler/Mercury.options:
Require the new modules to have the declarations and definitions
of their predicates in a consistent order.
compiler/mercury_compile_mlds_back_end.m:
Import mlds_to_java_file.m instead of mlds_to_java.m.
compiler/mlds.m:

Update some references to the deleted file.
