Sure Bharat! <br>
<br>
Would you be interested in studying Shannon's trove of PowerPC
architecture documents <font size="2">(I sent the link again to
this mailing list a few days ago)</font> and comparing the
architecture and CCL's PPC register usage conventions to the ARMv8A
(aka "ARM64") and its register usage conventions? <br>
<br>
At the very least look through the collection and tell us which
documents are most useful for someone writing a compiler.<br>
<br>
Do you want to write an assembler and disassembler for the ARMv8A in
the CCL style (i.e. compatible with the CCL compiler)?<br>
I particularly like "LAP" (Lisp assembly language) notation over
typical assembler notations.<br>
This is useful for reading assembly language code into simulator
written in Lisp.<br>

<div>If we get a list of such topics/books/websites etc. I'd be
glad to start off now. Any one pls ?</div>

<div>One of our priorities is to write more internals
documentation <i>while</i> we work on the M1 port.
<div>Part of the discipline will include everyone keeping
(and checking in) their contemporary notes/<u>journals</u>,
which we will distill into a document “how to port CCL
to (yet) another processor” on an ongoing basis.<br>
<div>Another thing that is in the immediate plan is to
write “slow but correct” versions of all the <u>subprims</u> (e.g.
bignum arithmetic) <i>in Lisp</i>, which are all
currently written in assembly language for every CCL
target architecture. </div>

people should contribute. However some good
introduction to internals and updating
documentation would be very helpful. More
important than M1 port is we set this right.
We might get M1 running after some effort but
in a couple of years we will end up in a
similar situation and talk about funding
someone again.</span>

Nicolas - <br>
<br>
Just to be 100% clear about this: Clozure as
an entity does not exist anymore, nor does it
exist as a loosely organized cabal. At this
point Matthew Emerson manages the web domains
and owns Github account where CCL is hosted,
but that’s it. I’m sure he would welcome as
much help as anyone wants to provide and would
happily give commit privileges to anyone who
shows they can work on the code. If someone
would rather fork and go wild, that’d be fine
too. But really, no one should let themselves
be slowed down by thinking they need Clozure’s
permission to do something.<br>
