compiler/notes/index.html:
Remove this file as it is mostly out-dated. Most of the e-mail
addresses are obsoloete and it's generally better to contact the
developers list anyway, even regarding more recent work.
work_in_progress.html:
Remove two items that I know are _definitly_ done.

The compiler contains some code for the following features,
|
|
which are not yet completed, but which we hope to complete
|
|
at some time in the future:
|
|
<p>
|
|
|
|
<ul>
|
|
<li>
|
|
We have incomplete support for a new, more expressive design for representing
|
|
information about type classes and type class instances at runtime. When
|
|
complete, the new design would allow runtime tests of type class membership,
|
|
it would allow the tabling of predicates with type class constraints,
|
|
and it would allow the debugger to print type_class_infos.
|
|
|
|
<li> We have added support for dynamic link libraries (DLLs) on Windows.
|
|
This is not yet enabled by default because it has not yet been tested
|
|
properly.
|
|
|
|
<li> There is a new garbage collector that does accurate garbage
|
|
collection (hlc.agc grade). See the comments in
|
|
compiler/ml_elim_nested.m and the paper on our web page for more details.
|
|
|
|
<li> There is a `--generate-bytecode' option, for a new back-end
|
|
that generates bytecode. The bytecode generator is basically
|
|
complete, but we don't have a bytecode interpreter.
|
|
</ul>
|
|
<p>
|
|
|
|
We also have some code that goes at least some part of the way towards
|
|
implementing the features below. However, for these features, the
|
|
code has not yet been committed and thus is not part of the standard
|
|
distribution.
|
|
|
|
<p>
|
|
|
|
<ul>
|
|
<li> A new implementation of the mode system using constraints.
|
|
This is on the "mode-constraints" branch of our CVS repository.
|
|
|
|
<li> Support for aliasing in the mode system.
|
|
This is on the "alias" branch of our CVS repository.
|
|
|
|
<li> Support for automatic structure reuse (reusing old data
|
|
structures that are no longer live, rather than allocating
|
|
new memory on the heap) and compile time garbage collection
|
|
This is on the "reuse" branch of our CVS repository.
|
|
|
|
<li> Better support for inter-module analysis and optimization.
|
|
|
|
</ul>

<h2>
|
|
Work Not In Progress
|
|
</h2>
|
|
|
|
The compiler also contains some code for the following features,
|
|
but work on them has stopped, since finishing them off would be
|
|
quite a bit more work, and our current priorities lie elsewhere.
|
|
Still, these could make interesting and worthwhile projects
|
|
if someone has the time for it.
|
|
<p>
|
|
|
|
<ul>
|
|
<li> A SOAP interface.
|
|
|
|
<li> A bytecode interpreter, for use with the `--generate-bytecode' option.
|
|
|
|
<li> Sequence quantification
|
|
</ul>
