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.

Fix problems with the compiler-generated header files:

needed when a module is imported in a high-level C code
grade, and a grade independent `.mh' file, which contains
the prototypes for `:- pragma export' declarations.

Pass the default options in the DEFAULT_MCFLAGS environment
variable, not on the mercury_compile command line. This allows
the options to be overridden by the setting of MCFLAGS in the
Mercury.options file (options on the command line override
options in the MCFLAGS variable).
Estimated hours taken: 500
Add an alternative implementation of Mmake as part of the compiler.
The advantages of this are
- more accurate dependencies
- no `mmake depend' step
- less process creation (no processes are created to
build interface files).
Still to do:
- handle --split-c-files
- handle the IL backend properly
- library installation
- allow the compiler to be built and the nightly tests
to be run with `mmc --make'
compiler/make.m:
Control the build process.
compiler/make.program_target.m:
Build executables and libraries.
compiler/make.module_target.m:
Build C files, object files, interface files etc.
compiler/make.dependencies.m:
Work out the depenendencies between targets.
compiler/make.module_dep_file.m:
Record the inter-module dependencies between invocations of mmc.
compiler/make.util.m:
Utility predicates used by `mmc --make'.
compiler/compile_target_code.m:
This module will eventually contain the predicates used
to compile the target code files generated by the compiler
which are now in mercury_compile.m. (That will be done
as a separate change for ease of reviewing).
For now compile_target_code.m
compiler/mercury_compile.m:
Export the predicates used to compile target code.
Call make.m.
Pass the name of the top-level module in the source file to modules.m.
It is needed when generating the `.module_dep' files.
Lookup the option defaults (which will eventually be stored in
DEFAULT_MCFLAGS by the mmc script) before compiling. Up until now
the option defaults have been passed on the command line by the
mmc script, but with `mmc --make' the default options need
to be overridden by the value of the MCFLAGS make variable, but
the MCFLAGS make variable is overridden by command line options.
Pass the value of `--link-flags' to c2init.
Remove some uninformative messages printed when a C, IL, etc.
compilation fails.
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:

definitions where not getting set correctly when building the
*_init.c file, because various references to `%_init.c' in this

Fix Mmake's handling of linker options.
scripts/Mmake.vars.in:
Add Mmake variables LDFLAGS, used for linker flags for
executables, and LD_LIBFLAGS, used for linker flags for
shared libraries. The separate variables are need because
on some architectures `ml' invokes the C compiler, but
`ml --make-shared-lib' invokes the linker directly.
Put `--' before CFLAGS in the construction of ALL_MGNUCFLAGS
to avoid confusion between C compiler options and mgnuc
options.
compiler/modules.m:
Pass LDFLAGS and LD_LIBFLAGS to ml.
doc/user_guide.texi:
Document CFLAGS, LDFLAGS and LD_LIBFLAGS.
scripts/parse_ml_options.sh_subr.in:

`--print-shared-lib-link-command', which print
the commands ml uses to link executables and
shared libraries.

Improve the handling of the mdb's `--window' option.
`mdb --window' now creates a window for mdb, not the program.
The main advantage of this is that redirection of the program's
input and output now works. The new behaviour should also be
implementable using the Windows API. The old behaviour is still
available with `mdb --program-in-window'.
Unfortunately, the code to open a pseudo-terminal for mdb's I/O
isn't very portable. It works on everything we run nightly tests on,
but isn't likely to work on older systems or BSD systems.
NEWS:
Document the change.
scripts/mdb.in:
Handle the new behaviour of `--window'.
Add `--program-in-window'.
trace/mercury_trace_internal.c:
If `--window' was passed in MERCURY_OPTIONS, redirect
mdb's I/O to a window created using `xterm -S'.
Rename occurrences of `close' to avoid gcc warnings.
runtime/mercury_trace_base.h:
runtime/mercury_trace_base.c:

runtime/mercury_signal.h:
runtime/mercury_signal.c:
Add a version of MR_setup_signal which doesn't cause
system calls to be restarted after a signal is received.
This is needed to allow a read() from the mdb window
to timeout if the window failed to start.
Add functions to get and set the action for a given signal.
