<h2>Summary:</h2>
Support for Intel Macs and x86-64 under Linux, a brand-new
replacement for ml-lex, and other minor improvements as well
as bugfixes.
<hr>
<h2>Details:</h2>
<dl>
<dt>Lexer generator:</dt>
<dd>
<ul>
<li>A new, much improved lexer generator tool has been developed by
Aaron Turon and John Reppy. The new tool, called <tt>lexgen</tt>, can be
used as a drop-in replacement for <tt>ml-lex</tt>.</li>
<li>The compilation manager is able to have lex specification
files processed by either <tt>lexgen</tt> or the original
<tt>ml-lex</tt>. For the time being, the latter is the default.</li>
<li>To change this aspect of CM's behavior, invoke <tt>sml</tt>
(and related commands such as <tt>ml-build</tt>) using the
<tt>-Ccm.use-legacy-lex=false</tt> command line switch.
Alternatively, one can define an environment variable
<tt>CM_USE_LEGACY_LEX</tt> and set it to <tt>false</tt>.</li>
<li>Binaries (bootfiles) shipped with this version have been
compiled using <tt>lexgen</tt>.
</ul>
</dd>
<dt>Newly supported platforms:</dt>
<dd>
<ul>
<li>SML/NJ builds and runs on Intel-based Macs running Mac OS X.</li>
<li>SML/NJ builds and runs on x86-64 systems using 32-bit mode.</li>
<li>SML/NJ should build and run on NetBSD 3.x (untested).</li>
</ul>
</dd>
<dt>Platforms no longer supported:</dt>
<dd>
<ul>
<li>Support for pre-2.2 Linux kernels has been dropped.</li>
</ul>
</dd>
<dt>Runtime system:</dt>
<dd>
<ul>
<li>Signal handling on x86/Linux has been cleaned up.</li>
</ul>
</dd>
<dt>MLRISC:</dt>
<dd>
<ul>
<li>Scripts for rebuilding MLRISC-generated files have been updated
to reflect changes to CM.</li>
</ul>
</dd>
<dt>Backend:</dt>
<dd>
<ul>
<li>Darwin-specific Intel ABI (for foreign-function interface)
implemented. The solution is temporary since it currently relies
on the fact that the compiler itself does not use the FFI.</li>
</ul>
</dd>
<dt>Compilation manager:</dt>
<dd>
<ul>
<li>Improved CM-specific error reporting and handling.</li>
</ul>
</dd>
<dt>Installation:</dt>
<dd>
<ul>
<li>Enabling <tt>$/html-lib.cm</tt> in config/preloads now works.</li>
</ul>
</dd>
<dt>CML:</dt>
<dd>
<ul>
<li><tt>withNack</tt> wrapped around a <tt>never</tt> event will
now properly signal the negative acknowledgement.</li>
</ul>
</dd>
