As we discussed, it has fallen into disuse. Its main purpose was to
pave the way for the .net backend and later for the java and csharp grades.
Now that the .net backend is ancient history and the java and csharp grades
are established, that purpose is gone, and for every other purpose,
hlc is better because it is simpler and faster.

Remove the architecture string from the installed directory structure
and put the executables in $PREFIX/bin, instead of
$PREFIX/lib/mercury/bin/$FULLARCH.
The reason for this change is to reduce the need for unix shell scripts in
the top-level bin directory that call the actual programs in the
lib/mercury/bin/FULLARCH directory. The unix scripts can't be run on Windows
without a unix emulation environment like Cygwin.
Because the executables are now in the top-level bin directory, we cannot
install multiple architectures under the same directory structure. However
this is not a real loss, since the binaries for different architectures can
just be installed to different locations, as we currently do anyway on
mundula.cs.mu.oz.au.
The plan is to rename mercury_compile to mmc and do away with the mmc unix
script. This will allow mmc to be run on Windows without Cygwin or MSYS.
This proposal replaces a previous proposal to implement a C version of the
mmc script. That solution turned out to be quite complicated and
unreliable.
This diff will also mean mdice, mslice and mtc_union will be in the same
directory as mmc, so will be in the PATH as long as mmc is in the PATH.

Fix linking error for hlc.par.gc grade on Darwin. The problem was that the
"-undefined suppress" option is not allowed with two level namespaces.
The solution is to use "-undefined dynamic_lookup" instead.
However this means the MACOSX_DEPLOYMENT_TARGET environment variable must be
set to 10.3 since this feature will not work on Mac OS < 10.3. To allow
hlc.gc.par to be built on Mac 10.3, but targetted for Mac OS 10.0 - 10.2 add
a configuration option to force the use of flat namespaces (the
"-undefined suppress" option may be used with flat namespaces).

Allow reconfiguration of existing installations, for example
to use a different C compiler. The reconfiguration works
by making a new copy of the scripts and mercury_conf.h,
and storing them in a partial installation directory tree
which uses the libraries and executables from the existing
installation.
Use this method to configure binary distributions, rather
than using a cut down version of the configuration script,
to avoid code duplication and to handle the case where the
C compiler in use on the installation machine is different
than that used to build the binary distribution.
This is more robust than the previous method of using a different
C compiler, which was to set the MERCURY_C_COMPILER variable and
hope the different C compilers were compatible enough.

Make it easier to use shared libraries on x86 with

There is now a third kind of object file, `.lpic_o'.
These files are compiled with `--pic-reg' but not with

On x86, executables which are linked with shared Mercury
libraries now depend on $(main_module.lpic_os), not
$(main_module.os).

compiler/options_file.m:
Read files containing Make style variable assignments.
compiler/options.m:
doc/user_guide.texi:
Add a new options category: build system options.
Add some extra options:
--warn-undefined-options-variables - like mmake --warn-undefined-vars
--verbose-commands - print commands that the user might be
interested in, like C compilation, but not things
like mercury_update_interface.
--output-compile-error-lines - print the first n lines
of the error file generated by a command.
--generate-mmc-make-modules-dependencies - generate dependencies
for use by `mmc --make' even when using Mmake.
--il-assembler, --ilasm-flags, --mcpp-compiler, --mcpp-flags,
--csharp-compiler, --csharp-flags, --install-prefix,
--install-command, --libgrades, --options-files,
--options-search-directories.
compiler/modules.m:
Add fields to the `module_imports' type for use by make.*m.
Don't try to fill in fields of the module_imports structure
lazily. It's error prone, and probably doesn't save much
anyway.
Clean up the code to compute what foreign languages
are used by a list of item.
Simplify the handling of fact tables by recording that a module
containing fact tables has foreign code to implement them,
rather than requiring separate checks everywhere.
Generalise predicates like get_interface so that they
work even after the imported items have been read.
Fix the handling of header files with the LLDS backend.
Install the `.module_dep' files created for use by
`mmc --make'.
compiler/*.m:
Use record syntax rather than explicit deconstruction to
refer to fields of the `module_imports' type.
compiler/*.m:
Be more careful about where output goes.
mercury_compile.m sets the output stream to be io__stderr_stream
at the start of compilation, so remove all explicit writes to
io__stderr_stream (with `--make' the error output stream may be
a `.err' file, not io__stderr_stream).
Change all occurrences of io__tell/io__told to use
io__open_output/io__close_output (io__told restores the current
output stream to io__stdout_stream, not the previous value).
compiler/passes_aux.m:
Make the output from system commands go to the current
output stream, not C stdout and stderr.
Allow commands to be printed with `--verbose-commands'.
Remove uninformative error messages when a command fails.
compiler/timestamp.m:
Add functions oldest_timestamp and newest_timestamp.
compiler/llds_out.m:
Record the number of C files written with `--split-c-files'
in <module>.num_split.
compiler/prog_io.m:
compiler/*.m:
`search_for_file' now returns the directory in which the
file was found.
compiler/foreign.m:
Use sub-typing to make some calls to predicates in this
module `det' rather than `semidet'.
compiler/handle_options.m:
Return the option arguments.
compiler/Mmakefile:
make.util.m refers to kill() and `struct sigaction' which
are not exported from <signal.h> unless `--no-ansi' is
passed to gcc.
compiler/notes/compiler_design.html:
Document the new modules.
runtime/mercury_signal.h:
runtime/mercury_signal.c:
Add a function MR_signal_should_restart() which alters
whether a signal restarts or interrupts system calls.
In general restarting is the preferred behaviour, but
the wait() for a child process needs to be interruptible.
scripts/Mmake.vars.in:
Add subdirs for `.module_dep', `.err_date'
and `.num_split' files.
library/io.m:
Add a version of io_call_system which returns the signal
that killed the command rather than converting it into
an error message.
Add a predicate to interpret the result of system() or wait().
library/list.m:
Add list__map_foldl2 and a unique mode for list__foldl3.
NEWS:
Document the new library predicates.
configure.in:
runtime/mercury_conf.h.in:
Check for siginterrupt().
doc/user_guide.texi:
Document the new options.
Add a description of `mmc --make' to the "Using Mmake" chapter.

Find the version number of the mscorlib assembly and record it in
MS_DOTNET_LIBRARY_VERSION.
compiler/mlds_to_il.m:
doc/user_guide.texi:
Use and document the option --dotnet-library-version. This option
is used to determine what version of the .NET standard libraries
that we are using.
compiler/mlds_to_il.m:
We no longer need to hard-code the hash for the mscorlib.dll.

Use the autoconfigured MS_DOTNET_LIBRARY_VERSION to set the
--dotnet-library-version. This is commented out for the moment
until this change bootstraps.

Finish the change to allow installed Mercury libraries to be
used directly by mmc.
bootstrap CVS tag: bootstrap_20011119_fullarch_opt
scripts/mmc.in:
Pass the value of the `--fullarch' option determined
at configuration time.
configure.in:
Test for the `--fullarch' option. Remove an old test
for `.c_date' files.

The compiler usually considers a file extension to include the `.',
so pass `.o' rather than `o' as the value of `--object-file-extension'.
This change avoids the need to handle `--executable-file-extension' (which
can be empty) as a special case.
scripts/mmc.in:
Pass `.o' as the value of `--object-file-extension', rather than `o'.
compiler/mercury_compile.m:
Remove code to prepend a `.' to the value of `--object-file-extension'
before passing it to `module_name_to_file_name'.
compiler/options.m:
Update the default values for the various `--*-extension' options
to include the `.'.
Estimated hours taken: 0.25
scripts/mmc.in:
When invoking mercury_compile to check whether it supports
`--cflags-for-threads', make sure that we redirect stdin
from /dev/null, to ensure that the test doesn't hand if
debugging is enabled.

Fix a bug: mmc wasn't passing the right flags to the C compiler
when `--parallel' was specified.
configure.in:
Set CFLAGS_FOR_THREADS, using code adopted from the code
in scripts/mgnuc.in.
scripts/mgnuc.in:
Use CFLAGS_FOR_THREADS rather than doing the case analysis
here.
scripts/mmc.in:
Pass `--cflags-for-threads $CFLAGS_FOR_THREADS' to mercury_compile.
compiler/options.m:
Add a new option `--cflags-for-threads', for use by scripts/mmc.in.
compiler/mercury_compile.m:
If --parallel is enabled, pass the --cflags-for-threads
options to the C compiler.
bindist/bindist.build_vars.in:
Pass on CFLAGS_FOR_THREADS.

Enable the options --c-flag-to-name-object-file and --object-file-extension.
These changes are tagged with bootstrap_20000707_obj_ext.
configure.in:
The bootstrap compiler is only recent enough if it accepts the
--object-file-extension flag.
scripts/mmc.in:
Used the autoconfed values to set -c-flag-to-name-object-file and
--object-file-extension defaults.
Estimated hours taken: 0.1
mmc.in:
We cannot just comment out the --c-flag-to-name-object-file and
--object-file-extension flags, as that destroys the line
continuations. Instead remove the options from inside the execs,
and leave them with a comment that they need to enabled when a
compiler that understands these flags bootstraps.
Estimated hours taken: 0.1
scripts/mmc.in:
Fix a bootstraping problem, the options --c-flag-to-name-object-file
and --object-file-extension can't be set by the mmc.in script until
a compiler exists that recognises them, so comment them out. The
defaults for these flags are the unix flags.

Changes needed to get
mmc --grade hlc.gc file.m
producing an executable, using MSVC as the compiler.
compiler/options.m:
Add the flags --c-flag-to-name-object-file and
--object-file-extension. --c-flag-to-name-object-file is the flag
the C compiler uses to name object files (ie -o for gcc, /Fo for
MSVC). --object-file-extension is the extension used by object
files on the current system.
compiler/mercury_compile.m:
Use the values of --c-flag-to-name-object-file and
--object-file-extension to generate the command line to compile
C files.
scripts/mmc.in:
Set the default values of the two new flags from the autoconfed
settings.
configure.in:
Set the value for CYGPATH, a utility which transforms between unix
and window paths. This is just echo under unix.
scripts/ml.in:
Use the autoconfed extension for the library files.
Use the autoconfed flag to add a path to list of directories to be
searched for libraries.
Make static libraries the default on cygwin systems.
Factor out the code which determines all the flags to be passed to
the linker.
Add an autoconfed variable LINK_OPT_SET which is the flag used to
indicate that all the options following this flag are to be passed
on to the linker.
Use the autoconfed setting for CYGPATH to transform the path to
static libraries into the correct format.

Fix a bug where tools/bootcheck was failing the
tests/hard_coded/split_c_files test case.
scripts/mmc.in:
Add a new environment variable MERCURY_MC_ALL_C_INCL_DIRS
which can be used to override MERCURY_C_INCL_DIR;
it is similar to the MERCURY_ALL_C_INCL_DIRS used by mgnuc,
except that it should contain `--c-include-directory' options
rather than `-I' options.
tools/bootcheck:
Pass down MERCURY_MC_ALL_C_INCL_DIRS,
just like the way we pass down MERCURY_ALL_C_INCL_DIRS.
Estimated hours taken: 0.5
scripts/mmc.in:
Move the `-I $INTDIR' so that it goes *after* the user's arguments
to mmc, rather than before. This ensures that any directories that
the user specifies using `-I' options are searched before the
standard Mercury library directory, which is consistent with
the way `-L' and `-R' options are currently handled.
This patch is needed to allow `-I ..' specified in Mmakefile in
extras/clpr/samples to work. Otherwise, it uses the installed
`.int' files, but links with the local (and potentially different)
libraries, resulting in link errors.
Estimated hours taken: 0.25
scripts/mmc.in:
Set the MERCURY_LPSOLVE environment variable to the full path
"@BINDIR@/lp_solve", if not already set, so that it won't matter
if users have another command called `lp_solve' in their path.
