--no-ansi (mgnuc) and --no-ansi-c (mmc) have not actually done anything for
many years now. Deprecate these options and remove their "use" throughout most
of the Mercury system. (The remaining uses are in the Makefiles for the Boehm
GC, which need to be updated separately.)

Conform to the above change.
NEWS.md:
Announce the above.
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.

Fix incorrect makefile rule with multiple targets.
A rule with multiple targets is equivalent to writing many rules,
each with one target, so the bison rule would (in parallel make)
run bison once for the .c target and once for the .h target.
The solution is to use a pattern rule, which GNU make recognises
as a single recipe generating multiple outputs.

Fix Mantis bug #45, which was that mdb effectively ignored some commands
in .mdbrc files.
trace/mercury_trace_internal.[ch]:
trace/mercury_trace_command_queue.[ch]:
Move the code for manipulating the command queue from
mercury_trace_internal.c to a new module. This improves the level of
abstraction. The ultimate cause of the bug was a lack of abstraction.
The old code put commands from startup files in the command queue
in a mixed order: respecting order within each startup file, but
reversing order among startup files. The cause of the bug was
that the commands from .mdbrc files were put into the queue
*after* the commands from the system's standard startup file in time,
but *before* them in order, so the commands in the standard startup
file could override commands from .mdbrc files.
The fix is to consistently put commands in order: from the standard
system startup file, from .mdbrc, and from the environment.

Fix a typo that caused the shared version of the event spec library

Estimated hours taken: 32

The objective of this diff is to switch from a table of solver events built
into the compiler (and eventually the debugger) into a table of events
defined by a file provided by the user to the compiler, which the compiler
then records in the executable for use by the debugger.
The current design, for speed of implementation, uses temporary files parsed
by a bison-generated parser. Since the compiler needs to be able to invoke
the parser even if it is compiled in a non-debug grade, the parser is in
a new library, the eventspec library, that is always linked into the Mercury
compiler and is always linked into any Mercury program with debugging enabled
(but is of course linked only once into a Mercury compiler which has debugging
enabled).
Modify the debugger to give it the ability to print the attributes of
user-defined events (for now, only the non-synthesized attributes).

Extend some of these commands so that if given no arguments, they report
the current values of the parameters they would otherwise set.
Replace the "set" commands of the mdb browser and of the declarative debugger
with a bunch of commands: "format", "depth", "size", "width", "lines",
"actions" and "params" (the last prints the current value of the parameters).
For each category of mdb commands, create files mercury_trace_cmd_<cat>.[ch],
and move the functions dealing with that category of commands there from
mercury_trace_internal.c. Give each of these new files a logical structure
that was sometimes missing from the relevant parts of mercury_trace_internal.c.

Branches: main
Add two new capabilities to the debugger.
The first capability is the idea of "held variables", variables that the
debugger holds onto even when execution has left the event they came from.
You can hold onto a variable via the mdb command "hold varname heldvarname".
You can suffix the name of the existing variable with a term path, in which
case the new held variable will refer only to the specified part of the term.
Later mdb commands can refer to the held variable by prefixing its name with
a dollar sign. For example, after "hold HeadVar__1^2 x", "$x" will refer to
the term that was the second argument of HeadVar__1 at the program point
at which the "hold" command was executed.
The second capability is the ability to compute the diff of two terms and
express those diffs as the term paths of the function symbols at which the two
terms differ, instead of the line numbers you get by using save_to_file and the
usual Unix diff command. The mdb command is "diff var1 var2". We limit the
number of term paths of difference sites that we display at any one time;
the mdb diff command has options to control this.
NEWS:
Mention the new capabilities.
doc/user_guide.texi:
Document the new mdb commands "hold" and "diff", the new mdb command
"held_vars" which simply lists the names of all the held variables

Improve the way we install grades. Making temporary backups of the

reasons. First, if the install fails, the cleanup script, which is
necessary for user friendliness, destroys any evidence of the cause.
Second, the restore of the backup wasn't perfect, e.g. it left the
.d files modified to depend on .mih files, which don't exist in
LLDS grades, and also left altered timestamps.
This diff changes the install process to make a single tmp_dir
subdirectory of the workspace, with all the work of install_grade

Changes to get shared libraries to work on Mac OS X (Darwin).
This is phase 2 of 2. Phase 1 added the compiler options described below.
Phase 2 uses these compiler options in the configuration scripts.
Darwin shared libraries have the extension `dylib' instead of `so'. Also
objects that link to a shared library on Darwin don't need to be told the
runtime path in which they should look for the libraries, instead the
shared libraries themselves remember where they will be eventually installed
(called the install-name) and any object which links in the shared library will
get the install-name from the shared library at link time. When a shared
library is built it has to be told where it will be installed which is what
the libtool -install_name option is used for on Darwin.
This diff only enables shared libraries on Darwin, not "bundles" which are
shared objects that can be loaded dynamically at runtime using something like
dlopen. Therefore the interactive query tool in the debugger still doesn't
work on Mac OS X.
Added three new compiler options :
--shlib-linker-use-install-name :
A boolean flag to tell the compiler to use the -install_name option
when building shared libraries. When this flag is set the following
options have no effect: --linker-rpath-flag, --linker-rpath-separator,
--shlib-linker-rpath-flag, --shlib-linker-rpath-separator.
--shlib-linker-install-name-flag :
The flag name to use ("-install_name" for Darwin).
--shlib-linker-install-name-path :
The path where the shared library will eventually end up, excluding the
file name. The file name is appended to the end before the option
is passed on to the linker.
Mmake.common.in
Added variables used for install-name on/off switch and flag name.

Add support for interfacing Mercury with the MPS garbage collector.
This change is broken into three parts:
1. Import version 1.100.1 of the MPS kit into the Mercury
CVS repository, in the directory `mps_gc'.
2. Make some changes to the MPS kit for Mercury,
to support fully-conservative collection and tagged pointers,
and to wrap it in an interface that is similar to that of
the Boehm collector.
3. Modify the rest of the Mercury implementation
to support linking with the MPS kit instead
of the Boehm collector. This involved defining
`mps' as a new GC method and a new grade component.
This is part 3 of 3.

Harmonize the treatment of the builtin types by the runtime system across
the MLDS and LLDS C backends. (Their treatment by the .NET and Java backends
is unchanged, at least for now.)
Previously, the RTTI data structures and unify and compare predicates for the
builtin types were defined in runtime/mercury.c for the MLDS backend but in
library/{builtin,private_builtin,type_desc}.m for the LLDS backend. This
make several kinds of maintenance difficult, and more likely to be forgotten.
The two backends also had their generic unify/compare code in different modules
(mercury.c and mercuy_ho_call.c) and used distinct macros for defining RTTI
data structures. This change fixes those problems by defining a consistent
set of macros (with backend-specific implementations but backend-independent
semantics), concentrating the definitions of all the RTTI structures and of all
the unify and compare predicates for builtin types in a new module in the
runtime, mercury_builtin_types.[ch], and concentrating all the generic
unify/compare predicates in mercury_ho_call.[ch].
This change also makes the runtime use consistently module qualified names
for the RTTI data structures for the builtin types. Since they are not module
qualified by the Mercury compiler, we module qualify them by macros that map
the mmc-generated names to the ones expected by the runtime system. This makes
it easier to use the same macros in LLDS and MLDS grades.
runtime/mercury_builtin_types.[ch]:
New module to contain all the C code for the implementation of
unify and compare predicates for the builtin types. Its contents
comes from mercury.c in the runtime (for the MLDS C backend) and
builtin.m, private_builtin.m and type_desc.m in the library (for the
LLDS C backend).
The unify/compare predicates for tuples now report errors. This is
necessary because the tuple is a variable arity constructor. Their
previous implementations for the MLDS backend relied on only being
called from the generic unify/compare routines with a nonstandard
interface, being passed a typeinfo for the tuple type, rather than
the typeinfos for the arguments of the type constructor. This worked
because we don't currently specialize unifies/compares of tuple types,
but was a potential problem if we ever started to do such
specialization. The fix is to handle tuples in the generic
unify/compare routines, just as in the LLDS backend.
runtime/mercury_ho_call.c:
Move the generic unify/compare routines for the MLDS backend here
from mercury.c.
Conform to the coding standard wrt indentation.
runtime/mercury_ho_call.h:
Declare the generic unify/compare routines for both backends.
Delete a typedef that now needs to be in mercury_types.h to avoid
circular dependencies.
runtime/mercury_type_info.h:
Use the same macros for defining type_ctor_info structures for the MLDS
and LLDS backends.
This required moving the definitions of MR_UnifyFunc_N and
MR_CompareFunc_N here from mercury.c.
runtime/mercury_hlc_types.h:
A new file containing definitions of types needed by the MLDS C
backend. These definitions used to be in mercury.h, but now they are
needed in mercury_type_info.h, a header file that doesn't and shouldn't
include mercury.h. They can't easily be put in mercury_types.h because
they depend on mercury_std.h, and we are not allowed to include
mercury_std.h in mercury_types.h.
runtime/mercury.h:
Delete the definitions of the C types representing type_info and
pseudo_type_infos, since these are now in mercury_type_info.h.
#include mercury_type_info.h.

runtime/mercury.c:
Delete the definitions of the C types representing unify and compare
predicates, since these are now in mercury_type_info.h.
runtime/mercury_bootstrap.h:

it makes it easier to use the same macros to define RTTI structures
in the LLDS and MLDS backend. (Previously, mercury_bootstrap.h had
macros to delete such module qualification for the variable arity
types.)
runtime/mercury_types.h:
Move some type definitions from mercury_ho_call.h and
mercury_deep_profiling.h to mercury_types.h to prevent problems

trace/mercury_trace_vars.c:
Use a now backend-independent macro to refer to a type_ctor_info.
trace/Mmakefile:
Do not define MERCURY_BOOTSTRAP_H, since mercury_bootstrap.h now
contains some definitions needed by code in the trace directory.
Replace it with MR_NO_BACKWARDS_COMPAT.
util/mkinit.c:
Module qualify the references to the RTTI structures of builtin types,
since the generated _init.c files don't include mercury_bootstrap.h.
Note that after this change has bootstrapped, we should be able to
delete those references, since they were only needed to give the
runtime access to the addresses of RTTI structures that used to be
defined in the library, but are now defined in the runtime.

Implement source-linking commands for mdb, using the new client/server
feature of vim. New commands added to mdb are 'view', which opens a
source-linked window if there is not one already open, and 'view -c'
which shuts any open source window.
This feature requires a version of vim compiled with '+clientserver'.
If such a program cannot be found, the mdb commands produce an error
message and do nothing else.
trace/mercury_trace_internal.c:
Implement the new mdb commands.
Add a new global variable which stores the information required
for one source server.
Every time mdb stops at an event, synchronise the source window
if present with the source context of the event. At interface
events, we use the parent context if possible, since that is more
useful information.
When leaving mdb, close the source window if there is one open.

On platforms which support it, check that there are no undefined
symbols when linking the Mercury shared libraries.
Some platforms (AIX, Windows, and BeOS) require this when building
shared libraries. This change means that we check it on our usual
platforms, including Linux.
configure.in:
Set ERROR_UNDEFINED to `-Wl,--no-undefined' on x86 Linux.
Using --no-undefined on Linux requires linking in ld-linux.so,
so add some code to figure out the right version of that to
link with.
Mmake.common.in:
Set ALLOW_UNDEFINED and ERROR_UNDEFINED to the values
determined by configure.in. Also pass down the values of
SOCKET_LIBRARY, NSL_LIBRARY, and DL_LIBRARY, since we need
to link with those libraries to resolve all the undefined
symbols.
