41d133b8ad Update the "no export" criteria and message.
compiler/check_module_interface.m:
    Generate a "this module does not export anything" warning for modules
    that contain only single include_module declaration, since such modules
    could be deleted with no effect.

    Change the warning message to list every kind of declaration/definition
    that does not depend on the presence of other kinds of declarations or
    definitions.

deep_profiler/Mercury.options:
    Shut up this warning for mdprof_fb, since right now, it contains
    only a single include_module, even it is designed to later contain more.

409cbcb6a3 Unify getopt.m and getopt_io.m ...
... using an approach proposed by Peter, with an extra twist from Julien.

Instead of having two modules, getopt.m and getopt_io.m, with the former
defining predicates that do not take an I/O state pair, and the latter
defining predicates that do take an I/O state pair, put both kinds of
predicates into a single module. The versions with an I/O state pair
have an "_io" suffix added to their names for disambiguation.
Both versions are a veneer on top of a common infrastructure,
which relies on a simple type class to implement the operation
"give the contents of the file with this name". The predicate versions
with I/O state pairs have a normal implementation of this typeclass,
while the predicate versions that do not have I/O state pairs
have an implementation that always returns an error indication.

The above change just about doubles the number of exported predicates.
We already had two versions of most exported predicates that differed
in whether we returned errors in the form of a string, or in the form
of a structured representation, with names of the latter having
an "_se" suffix. Since we agreed that the structured representation
is the form we want to encourage, this diff deletes the string versions,
and deletes the "_se" suffix from the predicate names that used to have them.
(It still remains at the end of the name of a type.) This "undoubling"
should offset the effect of the doubling in the previous paragraph.

Eventually, we want to have just one module, getopt.m, containing
the updated code described above, but for now, we put the same code
into both getopt_io.m and getopt.m to prevent too big a shock to
people with existing code that uses getopt_io.m.

b8b845a568 Fix mmakefile rules for os,cs,css,javas.
The main objective of this change is to get bootchecks in the csharp
and java grades to actually build the slice, profiler, deep_profiler
and mfilterjavac directories, which (due to the bug this diff fixes)
they weren't doing before.

However, since one side effect of this change is to eliminate
one source of annoying warnings from mmake about references to undefined
variables, a subsidiary objective is to eliminate other sources of such
warnings as well, which mostly come from the rules for making tags files.

browser/Mmakefile:
deep_profiler/Mmakefile:
library/Mmakefile:
mdbcomp/Mmakefile:
profiler/Mmakefile:
slice/Mmakefile:
ssdb/Mmakefile:
    When creating stage 3, the bootcheck builds, in each directory,
    only the files that it wants to compare against their stage 2 versions.
    This means that it wants to build all the .c, .cs or .java files,
    which it does via the cs, css and javas mmake targets.

    The correct definitions of the rules of these targets depends on
    whether mmc --make is being used or not, so we need at least two
    sets of definitions: one for mmc --make, and for no mmc --make,
    and conditionally selecting the appropriate one. The latter definition
    has the problem that it refers to mmake variables that are intended
    to be defined in .dv files created by mmc --generate-dependencies,
    but until that has been run, those mmake variables are undefined.

    Until now, the only directories that had both the mmc --make
    and the no mmc --make definitions were the ones needed to build
    the compiler. Bootchecks in the csharp and java grades, which
    always use --make make, got errors when they tried to build
    the directories that bootcheck builds after the compiler:
    the slice, profiler, deep_prof and mfilterjavac directories.

    This diff ensures that all directories we build in bootcheck
    get all both versions of the os, cs, css, and javas targets.
    In fact, they get two subversions of the no mmc --make version:
    one for use in the presence of .dv files, and one for use in their
    absence. The latter just builds the .dv files and invokes mmake
    again. This avoids one source of warnings about undefined mmake
    variables.

    To avoid another source, make the rules for tags files and their
    proxies depends on *.m instead of mmake variables such as $(mcov.ms),
    since this makes sense even before making dependencies. The only price
    is that any untracked Mercury source files in the directory have to
    either be given some other suffix, or moved somewhere else.

    Where relevant, make the mtags invocation prefer the master versions
    of files that are copied from the mdbcomp directory to other directories,
    since this is the only writeable version.

    Make the os and cs rules consistently NOT build the _init.[co] files.
    The way we use those files in bootcheck, we never need them;
    when we need them, the right target to give is the executable anyway.

    In the slice directory, don't put mcov between mtc_union and mtc_diff.

    Eliminate unnecessary duplication, e.g. of sources in rules.

    Eliminate double negatives in conditionals.

    Fix formatting.

a618ab31e1 Insist that without mmc -f, module a.b.c be in a.b.c.m.
This should fix Mantis bug #489, which shows that without this,
the compiler can mistakenly believe that a file with a name such as lexer.m
contains a module of the standard library, rather than a submodule named
test.lexer.

compiler/parse_module.m:
    Require that :- module declarations specify the expected name.
    The name may be expected because it exactly matches the filename
    (as above), or because mmc -f has recorded the actual name
    as the expectation.

    check_module_has_expected_name, since it is needed on its own.

ae4b736fdd Implement warnings for suspicious recursion.
compiler/simplify_goal_call.m:
    If the --warn-suspicious-recursion option is set, and if the warning
    isn't disabled, generate warnings for two different kinds of suspicious
    recursion. They are both related to, but separate from, the warning
    we have long generated for infinite recursion, which occurs when
    the input args of a recursive call are the same as the corresponding
    args in the clause head.

    Both kinds suspicious recursion look at the input args of a recursive call
    that are NOT the same as the corresponding args in the clause head.
    Both require these args to have non-unique modes. (If they have unique
    modes, then the depth of the recursion may be controlled by state outside
    the view of the Mercury compiler, which means that a warning would be
    likely to be misleading.)

    The first kind is when all these args use state variable notation.
    Most of the time, we use state var notation to denote the data structures
    updated by the recursive code; having variables using such notation
    *controlling* the recursion is much less common, and much more likely
    to be unintended. The motivation for the new option was this infinitely
    looping code, which resulted from neglecting to s/[X | Xs]/Xs/ after
    cutting-and-pasting the clause head to the recursive call.

    p([X | Xs], !S) :-
        ...,
        p([X | Xs], !S).

    The other kind of suspicious recursive call we warn about involve
    input arguments where the base names of the input arguments (the part
    before any numeric suffixes) seem be switched between the clause head
    and the recursive call, as here:

    q(As0, Bs0, ...) :-
        ...,
        q(Bs1, As, ...).

compiler/mercury_compile_main.m:
    Disable style warnings when invoked with --make-optimization-interface
    or its transitive variant. Without this, warnings about suspicious
    recursion would get reported in such invocations.

    Move a test from a callee to a caller to allow the callee to be
    less indented.

compiler/options.m:
    Export functionality to mercury_compile_main.m to make the above possible.

library/string.m:
    Add a predicate to convert a string to *reverse* char list directly.

    Note a discrepancy between the documentation and the implementation
    of the old predicate the new one is based on (which converts a string
    to a forward char list).

72f174b4e2 Don't print value of errno in MR_fatal_error.
The majority of calls to MR_fatal_error do not follow an operation that
sets errno, so printing out an error message unrelated to the reason for

call to MR_fatal_error. Fixes bug #464.

f519e26173 Add builtin 64-bit integer types -- Part 1.
Add the new builtin types: int64 and uint64.

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 'int64' and 'uint64' as builtin types.
- Extends the set of builtin arithmetic, bitwise and relational operators
  to cover the new types.
- Adds the new internal option '--unboxed-int64s' to the compiler; this will be
  used to control whether 64-bit integer types are boxed or not.
- Extends all of the code generators to handle the new types.
- Extends the runtimes to support the new types.
- Adds new modules to the standard library intend to contain basic operations
  on the new types.  (These are currently empty and not documented.)

There are bunch of limitations marks with "XXX INT64"; these will be lifted in
part 2 of this change.  Also, 64-bit integer types are currently always boxed,
again this limitation will be lifted in later changes.

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.)

9095985aa8 Fix more warnings from --warn-inconsistent-pred-order-clauses.
deep_profiler/*.m:
    Fix inconsistencies between (a) the order in which functions and predicates
    are declared, and (b) the order in which they are defined.

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

    In query.m, put the various commands in the same sensible order
    as the code processing them.

    In html_format.m, merge two exported functions together, since
    they can't be used separately.

    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.

deep_profiler/DEEP_FLAGS.in:
    Since all the modules in this directory are now free from any warnings
    generated by --warn-inconsistent-pred-order-clauses, specify that option
    by default in this directory to keep it that way.

All of these places were pointed out by the new --inform-incomplete-switch
option.

    As above. In some cases, this meant adding the missing cons_ids
    with a simple `fail' as the goal. In other cases, it meant adding
    comments on the `fail'. In yet other cases, it involved replacing
    semidet predicates with functions returning bools.

    In a few places, the code for the previously-missing cons_id
    throws an exception.

    In prog_mode.m and var_locn.m, the code for some previously-missing
    cons_ids is neither `fail' nor an abort, but code that does the actual
    job of the predicate it is in. In these cases, the fact that this code
    was previously missing seems to have been a bug.

092e175f45 Add a builtin unsigned word sized integer type -- Part 1.
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:
compiler/prog_data.m:
compiler/builtin_lib_types.m:
    Recognize uint as a builtin type.

    Add a new alternative to the cons_id/0 type corresponding to the uint type
    -- for bootstrapping purposes its argument is currently an int.

compiler/builtin_ops.m:
    Add builtin relational and arithmetic operations on uints.  Note that the
    existing 'unsigned_le' operation is actually intended for use with signed
    values.  Rather than attempt to modify its meaning, I have just added new
    operations specific to the uint type.

compiler/hlds_data.m:
    Add a new tag type for uints.

compiler/type_ctor_info.m:
    Recognise uint as a builtin.

    Bump the RTTI version number here.
