<h2>Summary:</h2>
The most important and noticable changes in 110.47 concern preliminary
implementations of the NLFFI foreign-function interface under Mac OS X
(PowerPC) and Win32 (x86). There are also a number of important bug
fixes.
<hr>
<h2>Details:</h2>
<dl>
<dt>NLFFI:</dt>
<dd>
<ul>
<li>preliminary support for Mac OS X added</li>
<li>preliminary support for Win32 added
(untested;
currently can only interface with C functions using the stdcall
calling conventions)</li>
<li>function arguments that are C unions are now handled</li>
<li>various minor bug fixes to ml-nlffigen</li>
<li>preliminary documentation for nlffi and ml-nlffigen
(currently only describes the output of ml-nlffigen;
see src/ml-nlffi-lib/Doc/manual/nlffi.tex)</li>
</ul>
</dd>
<dt>Compilation Manager:</dt>
<dd>
<ul>
<li>made <tt>make</tt> commend in CM's <tt>make</tt> tool
configurable</li>
<li>added option (default: <tt>on</tt>) for passing the name of
the SML/NJ's </tt>bin</tt> directory to <tt>make</tt>;
This can be used by the Makefile to, e.g., pick the "right" version
of ml-nlffigen.</li>
</ul>
</dd>
<dt>Basis:</dt>
<dd>
<ul>
<li>Changed the implementation of structure Unix so that the
same stream is returned every time one of the
<tt>{text,bin}{In,Out}streamOf</tt> functions is invoked on the
same proc. (NOTE: This is not what the spec says, so it will
probably change again. Don't rely on it!)</li>
</ul>
</dd>
<dt>Windows port:</dt>
<dd>
<ul>
<li>bug fixes:
<ul>
<li>NULL test in gmtime and localtime</li>
<li><tt>toSeconds</tt> -> <tt>toMilliseconds</tt> in
<tt>win32-process.sml</tt> (Basis implementation)</li>
</ul>
</ul>
</dd>
<dt>Installer:</dt>
<dd>
<ul>
<li>eliminated some shell syntax not understood by
<tt>/bin/sh</tt> under Solaris</li>
</ul>
</dd>
<dt>Compiler internals:</dt>
<dd>
<ul>
<li>low-level support for choosing C calling conventions by
twiddling the type of of the <tt>rawccall</tt> primop (see
<tt>src/compiler/Semant/types/cproto.sml</tt> for details)<li>
<li>use <tt>paramAlloc</tt> to report c-calls with too many
arguments (for PPC version where parameter area is
pre-allocated)</li>
<li>added <tt>ccall_maxargspace</tt> to machspec (to implement
the above)</li>
</ul>
</dd>
<dt>MLRISC:</dt>
<dd>
<ul>
<li>redesigned c-calls interface</li>
<li>c-calls implementation for ppc-macosx added</li>
<li>Added these instructions to the PowerPC architecture:
<tt>LWARX</tt>, <tt>STWCX</tt>, <tt>LBZU(X)</tt>,
<tt>LHZU(X)</tt>, <tt>LWZU(X)</tt>, <tt>STWU(X)</tt>,
<tt>STFDU</tt>, <tt>STFSU</tt>, etc.
(Instruction encodings not added yet, though.)</li>
<li>loop-structure.sml has been rewritten</li>
</ul>
</dd>
