bda87983d4 Move some code to new io.error_util module.
This reduces the size of io.m a bit. The other reason for moving the
code is to allow modules that occur in a dependency cycle with io.m
to read results from io.error_util.trans_opt, whereas they may have
been prevented from reading io.trans_opt.

library/io.m:
library/io.error_util.m:
    Move is_error, throw_on_error and other similar predicates to a
    new undocumented submodule of io.m.

    Also move the support functions/predicates used by those predicates.

    Make io.make_io_error_from_system_error and
    io.make_io_error_from_windows_error call the implementations in
    io.error_util.m.

05fd615471 Carve io.stream_ops.m out of io.m.
Also, move foreign code pieces still in io.m that belong in
previously-carved-out modules to those modules.

library/io.m:
library/io.stream_ops.m:
    As above. The new private submodule contains the implementations
    (helper predicates) of the operations that

    - open and close streams,
    - get and set offsets in those streams,
    - get and set line numbers on streams,
    - return the standard streams, and
    - set streams as the current streams.

library/io.m:
    Make some previously private includes public, to allow modules outside
    of io.m to refer to the C# and Java symbols they define. These includes
    are in the second, undocumented interface section of io.m.

    Delete the foreign code moved to io.primitives_{read,write}.m,
    as well as the foreign code moved to io.stream_ops.m.

    Change {get,set}_{line_number,output_line_number}/3, which used
    to be implemented directly using foreign_procs, to implement them
    in terms of their arity-4 counterparts which take an explicit stream
    argument, which now are in io.stream_ops.m. This can yield a slowdown,
    but it should be so small as to be unmeasurable on all non-microbenchmark
    workloads.

    Move related code together.

    Update module qualifications in C# and Java code.

    Delete the second #include of mercury_library_types.h.

    Delete the MR_{initial,final}_io_state macros.

    and one foreign_code per language.

c10366df16 Read and write bitmaps in bitmap.m, ...
... and obsolete the globals structure in the I/O state.

library/io.m:
    Move the implementations of the predicates that read and write bitmaps
    to bitmap.m. Leave forward predicates in io.m, but mark them obsolete.

    Mark the predicates that get, set and update the globals structure
    stored in the I/O state as obsolete.

    Export some functionality used by the moved code. The exports are
    in the second, undocumented interface section.

    Improve the names of some internal predicates.

    Add some module qualifiers to reduce type ambiguities.

library/Mercury.options:
    Disable obsolete warnings for io.m, to allow the initialization
    of the I/O state to initialize the globals as well; the globals
    are now marked obsolete, but they do still exist.

library/bitmap.m:
    Move the predicates for reading and writing bitmaps here from io.m.

    Add a "_range" suffix to the names of the predicates that read and write
    a range in a bitmap. Without this, both read_bitmap and write_bitmap
    existed with *four* arities. Now each of these predicates has only
    two arities: one with an explicit stream, and one without.

    Document a spot that may need double maintance.

    Move the hash functions before the predicates that do I/O.

001fb312b7 Attempt to fix gcc warnings for library/bitmap.c.
library/bitmap.m:
    Introduce det_byte_index_for_bit, which is like the existing
    byte_index_for_bit, but treats invalid (i.e. negative) indexes
    differently. Instead of returning -1 as a byte index for them,
    it aborts. It was this -1 that was the cause of (I think)
    all the warnings from gcc about -1 being used as an array index.

    Replace calls to byte_index_for_bit with calls to det_byte_index_for_bit
    at the call sites where inlining both this call and nearby calls to
    unsafe_{get,set}_byte allows gcc to figure out that the -1 from
    byte_index_for_bit could become the byte index value passed to
    unsafe_{get,set}_byte.

    Some of these call sites were in non-exported predicates that
    happened to ensure that the original bit index could never be
    negative. However, most were in the definitions of exported predicates
    or functions. This means that this diff can affect the behavior
    of user programs that call those predicates and functions.
    However, since old behavior was accessing arrays outside their bounds,
    leading to using effectively using random data as input to the
    rest of the computation, while the new behavior is an immediate abort,
    I would consider that a definite improvement.

    Fix an off-by-one reference to a clone of unsafe_set_byte.
    Delete the now-unused clone.

    Use "> 0" instead of "\= 0" in a if-then-else condition to test
    the result of an unchecked remainder operation when the divisor
    is positive, to allow the then-part to assume that the value being
    tested is NOT negative.

a815cf45e6 Eliminate overuse of ^s in library/bitmap.m.
library/bitmap.m:
    Replace all uses of field access notation for things that are not
    structure fields with getter functions and setter predicates.
    Add the getter functions and setter predicates where they did not
    exist before. Unlike the old "field :=" functions, the new setter
    predicates lend themselves to state variable notation.

    Replace nested applications of functions with sequences of calls
    (usually a get/modify/set sequence) that is easier to read and
    understand, partly because it gives meaningful names to the
    intermediate values.

    Where an operation was available as both a function and a predicate,
    implement the function version in terms of the predicate version,
    as is our convention in the rest of the Mercury implementation,
    instead of vice versa.

    In a few cases, where implementing the function in terms of the predicate
    could lead to misleading exceptions (that refer to the name of the
    predicate, not the function, even when the user called the function),
    have two copies of the implementation that differ only in the
    text of the exception(s) being thrown.

NEWS:
    Document the added exported functions and predicates.

tests/hard_coded/bitmap_empty.m:
    Replace io.write/io.nl sequences with io.write_line, including

f76e0407e5 Fix some error reporting in bitmap module.
The functions byte/2 and 'byte :='/2 both throw a bitmap_error/1 exception if
the given byte index is out of bounds.  The error message returned as part of
the exception reports the byte index that is out of bounds but then gives the
valid bounds of *bit* indexes in the bitmap.   There are two possible fixes:

     1. report the out of bounds index as the bit index of the start of the byte.
     2. report the valid bounds of the of byte indexes in the bitmap.

This change implements the latter.

Style and formatting fixes to the bitmap module.

library/bitmap.m:
     Make the above fix.

     Add separate predicates for reporting out of bounds bit and byte
     indexes.

     Do not provide erroneous functions that duplicate the functionality of,
     or forward their work, to erroneous predicates of the same name.

    are declared, and (b) the order in which they are defined.

    In most of these modules, either the order of the declarations
    or the order of the definitions made sense, and I changed the other
    to match. In a few modules, neither made sense, so I changed *both*
    to an order that *does* make sense (i.e. it has related predicates
    together).

    In some places, put dividers between groups of related
    functions/predicates, to make the groups themselves more visible.

    In some places, fix comments or programming style, give some auxiliary
    (non-exported) predicates better names, or delete some unneeded module
    qualifications.

    In some places, have the function form of a procedure forward
    the work to the predicate form, instead of vice versa, where this is
    more natural (usually because it allows the use of state variables).
    However, this is the only kind of "algorithmic" change in this diff;
    the rest is just moving code around.

696829e6c1 Fix problems with the char module.
(1) The behaviour of digit_to_int/2 was inconsistent with that of is_digit/2.
The former succeeds for all of 0-9, a-z and A-Z while the latter succeeds only
for 0-9 (i.e. it was possible for digit_to_int/2 to succeed for non-decimal
characters, which is not what was intended in many of it uses).

(2) Predicates involving hexadecimal digits were inconsistently named, they
were "hex digits" in one predicate name, "hex chars" in another.

This change ensures that the following operations are supported for binary,
octal, decimal and hexadecimal digits and that we use a consistent naming
scheme for the predicates that implement them:
    - testing if a character is a digit of the given base
    - conversion to an int
    - conversion from an int

In addition, we also add predicates for supporting these operations for user
defined bases, ranging from 2-36.

library/char.m:
    Add the predicate is_decimal_digit/1, which is a synonym for is_digit/1.

    Add the predicate is_base_digit/2.

    Add the predicates int_to_{binary,octal,decimal,hex}_digit/2 and
    base_int_to_digit/3.

    Add the predicates {binary,octal,decimal,hex}_digit_to_int/2 and
    base_digit_to_int/3.

    Add det function versions of the above.

    Delete the function det_digit_to_int/1 that I added the other day.

    Mark the following as obsolete:
        - is_hex_digit/2
        - int_to_hex_char/2
        - int_to_digit/2
        - det_int_to_digit/1
        - det_int_to_digit/2

    Avoid redundant module qualification in the implementation.

    Mark some C foreign_procs as not modifying the trail.

    should be ordered.

ab44bbad3f Use a better algorithm for unwinding version_arrays.
The old version_array rewind code used linear stack space in order to
perform it's updates in the right order (newest to oldest) by following the
structure's next pointers (which are a oldest to newest list).  I previously
introduced week prev pointers so that walking over this structure newest to
oldest could be done with constant stack space.  However that is less
efficient than the method suggested by Peter Wang.

Peter suggested using a bitmap and traversing oldest-to-newest, marking
each update in the bitmap and checking the bitmap before making any update.
Thus preserving older values over newer ones (which is good, this code
_rewinds_ updates).  This patch implements Peter's suggestion and removes
the prev pointers from the structure for C and Java backends.

Thanks to Peter Wang for giving me a hand with C#.

Branches: main

Deprecate string.substring, string.foldl_substring, etc. in favour of
new procedures named string.between, string.foldl_between, etc.
The "between" procedures take a pair of [Start, End) endpoints instead
of Start, Count arguments.  The reasons for this change are:

- the "between" procedures are more convenient

- "between" should be unambiguous.  You can guess that it takes an End
  argument instead of a Count argument without looking up the manual.

- Count arguments necessarily counted code units, but when working with
  non-ASCII strings, almost the only way that the values would be arrived at
  is by substracting one end point from another.

- it paves the way for a potential change to replace string offsets with an
  abstract type.  We cannot do that if users regularly have to perform a
  subtraction between two offsets.

library/string.m:
	Add string.foldl_between, string.foldl2_between,

7e26b55e74 Implement a new form of memory profiling, which tells the user what memory
Branches: main

Implement a new form of memory profiling, which tells the user what memory
is being retained during a program run.  This is done by allocating an extra
word before each cell, which is used to "attribute" the cell to an
allocation site.  The attribution, or "allocation id", is an address to an
MR_AllocSiteInfo structure generated by the Mercury compiler, giving the
procedure, filename and line number of the allocation, and the type
constructor and arity of the cell that it allocates.

The user must manually instrument the program with calls to
`benchmarking.report_memory_attribution', which forces a GC and summarises
the live objects on the heap using the attributions.  The mprof tool is
extended with a new mode to parse and present that data.

Objects which are unattributed (e.g. by hand-written C code which hasn't
been updated) are still accounted for, but show up in profiles as "unknown".

Currently this profiling mode only works in conjunction with the Boehm
garbage collector, though in principle it can work with any memory allocator
for which we can access a list of the live objects.  Since term size
profiling relies on the same technique of using an extra word per memory
cell, the two profiling modes are incompatible.

The output from `mprof -s' looks like this:

------ [1] some label ------
   cells            words         cumul  procedure / type (location)
   14150            38872                total

Also some miscellaneous fixes.


configure.in:
        Require a recent enough bootstrap compiler that recognises C# as a
        language for `pragma foreign_type'.

Mmakefile:
        Use `mmc --make' to install the standard library in csharp grade.

aclocal.m4:
        Search for the Mono C# compiler `gmcs', which is required for generics
        at this time.  Prefer it over the DotGNU C# compiler, which I have not
        tested.

        Search for `mono'.  If found, it will be used in shell scripts to
        launch executables generated via the csharp backend.

        Remove "MS_" prefixes on the variables MS_CSC and MS_ILASM, which are
        not Microsoft-specific.  More importantly, it should be less likely to
        make the mistake of adding an extra underscore to CSCFLAGS and
        ILASMFLAGS.

README.DotNet:

compiler/compile_target_code.m:
        Add new linked target types `csharp_executable', `java_launcher' and
        `erlang_launcher', instead of overloading `executable'.

        Link with `mer_std.dll' and other libraries when generating C#
        executables.  There is no `mer_rt.dll'.

        Pass "/debug" to the C# compiler if `--target-debug' is set.

        Create a shell script to launch the executable if necessary.

        Delete an unused predicate `standard_library_directory_option'.

compiler/file_names.m:
        `.cs' and `.cs_date' are grade-dependent.

compiler/handle_options.m:

        grades.

compiler/make.module_target.m:

        the extra underscore before "FLAGS".  In all uses of the variables,
        they were spelt without the extra underscore.

doc/user_guide.texi:
        Document options and file types related to the C# grade.

library/Mmakefile:

compiler/mlds.m:
        Rename `finality' to `overridability'.  The `final' keyword in Java
        has multiple meanings, so avoid that word.  Use the word `sealed'
        to describe classes or virtual methods which cannot be overridden,
        which is the keyword in C#.

compiler/ml_switch_gen.m:
        Remember the types of mlconst_foreign constants.  In the C# backend a
        foreign enum value needs to be cast to the right type.  For some

        Replace ml_gen_final_member_decl_flags with
        ml_gen_const_member_decl_flags.  Return flags with the `sealed' flag
        unset, as that wouldn't make sense for member variables.

57f9013259 Start a C# backend, adapted from mlds_to_java.m.
Branches: main

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.

compiler/mlds_to_cs.m:
        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
        conflict with.

        For C# we need to know if a `pragma foreign_type' is a value or
        reference type.  Currently this is done by accepting a fake keyword
        `valuetype' before the type name, like for IL.

compiler/mercury_compile_mlds_back_end.m:

compiler/handle_options.m:
        Handle `target_csharp' like `target_java', except for features which
        are still to be implemented.

compiler/add_pragma.m:
        Allow C# as a `pragma foreign_export' language.

        Allow C# for `pragma foreign_export_enum'.

        Conform to changes.

compiler/hlds_data.m:

        designed for the IL backend, which used a low-level representation of
        the RTTI data structures.

        Most (if not all) of the the "new" code is exactly the same as the Java
        versions, with only syntactic changes.

        Rename the C# class `void_0' to `Void_0' to match the naming convention
        used by mlds_to_cs.m.

library/array.m:
        Update the existing C# code to work with the new backend.

        Use `object[]' as the type of all array of non-primitive types.
        The problem is one we encountered on the Java backend: when creating a
        new array based on the type of a single element, we don't know whether
        the new array should contain elements of the class or superclass.

library/bool.m:
        Export `bool' constants to C#.

library/exception.m:

        those on the Java backend.

        Use enumerations `MR_TYPECTOR_REP_*' and `MR_SECTAG_*' constants so we
        can switch on them.

c053f90088 Allow inlining of Java foreign_procs.
Branches: main, 10.04

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.

c509c49bdc Add a mechanism for generating warnings when the various clauses of a predicate
Estimated hours taken: 24
Branches: main

Add a mechanism for generating warnings when the various clauses of a predicate
or function are not contiguous.

This mechanism consists of two options:

	--warn-non-contiguous-clauses
	--warn-non-contiguous-foreign-procs

The first option generates warnings when the Mercury clauses of a predicate
or function are not contiguous, but it ignores any foreign_procs of that
predicate or function, and thus allows these to be away from the Mercury
clauses and each other. This option is enabled by default.

The second option generating warnings unless both the Mercury clauses and
all the foreign_procs of the predicate or function are all contiguous.
This option is not enabled by default, because many library modules
group foreign_procs not by predicate, but by foreign language. (All C foreign
procs for a group of predicates, then all the Java foreign procs for that group
of predicates, etc.)

compiler/hlds_clauses.m:
	Store, next to the representation of each clause list, information
	about the locations (item numbers and context) of the clauses.
	We store two versions of this information, one version for each option.

	Make the predicates that access the clause list access the location
	information as well, to ensure that any code that adds clauses also
	records their location.

	Add a predicate that tests for non-contiguity.

	Add a specific type to represent the modes that a clause applies to.
	This replaces the error-prone scheme we used to use that represented
	the notion "this clause applies to all modes" with an empty list of
	modes. This allows us to remove the code in add_pragma.m that used
	to replace these empty lists with the list of actual modes they
	represented.

	Change the prefix on the fields of clauses_info to avoid ambiguities.
	Add a prefix to the names of the function symbols of the clauses_rep
	type to avoid ambiguities.

compiler/add_clause.m:
compiler/add_pragma.m:
	When adding Mercury clauses and pragma foreign_procs to a predicate or
	function, record the location of the clause or foreign_procs. We do so
	even if the clause or foreign_proc is overridden by another. For
	example, when compiling to C, a Mercury clause overrides an Erlang
	foreign_proc, and a C foreign_proc overrides a Mercury clause.

	Fix an old bug where a foreign_proc that should override Mercury
	clauses overrode only one Mercury clause, and left the others
	in the predicate, to yield a disjunction with some Mercury disjuncts
	and a foreign_proc disjunct. This disjunction would then yield
	determinism errors if it had outputs.

	The new code that fixes the bug has a much more direct implicit
	correctness argument, and should be significantly easier to understand.
	It also avoids doing unnecessary work. (The old code could make a
	decision to ignore a clause, yet still proceed to transform it,
	just to ignore the result of the transformation.)
