    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>

                          <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>
