<h3>Summary:</h3>
|
| 21 : |
|
|
<ul>
|
| 22 : |
|
|
<li>A long-standing signal-handling bug has been fixed.</li>
|
| 23 : |
|
|
<li>As a result, CML finally works again, and so does eXene.</li>
|
| 24 : |
|
|
<li>NLFFI has been further revised and improved. It now supports the
|
| 25 : |
|
|
Sparc architecture in addition to x86/Linux.</li>
|
| 26 : |
|
|
<li>There are various bugfixes and some organizational changes. </li>

<h4>NLFFI: </h4>
|
| 31 : |
|
|
<ul>
|
| 32 : |
|
|
<li>The types in the public interface to the "C" module have been simplified:
|
| 33 : |
|
|
the annoying 'f type parameter has been dropped in most places. This
|
| 34 : |
|
|
requires some cheating under the hood, but fortunately the cheat is a
|
| 35 : |
|
|
provably safe cheat.</li>
|
| 36 : |
|
|
<li>Various bugs in ml-nlffigen have been fixed so that it should be
|
| 37 : |
|
|
more robust now.</li>
|
| 38 : |
|
|
<li>C functions and function types that use variable-length argument
|
| 39 : |
|
|
lists are no longer rejected. Instead, ml-nlffigen will produce ML
|
| 40 : |
|
|
code that lets you call the function with just its mandatory arguments.
|
| 41 : |
|
|
This means that ml-nlffigen will not bail out just because there is
|
| 42 : |
|
|
one odd occurence of a varargs function somewhere in one big .h-file.</li>
|
| 43 : |
|
|
<li>Default names for files are now derived from the C files's basename
|
| 44 : |
|
|
so that ml-nlffigen will always place them in the current directory.</li>
|
| 45 : |
|
|
<li>Default names for generated ML identifiers are also derived from
|
| 46 : |
|
|
the C file's basename.</li>
|
| 47 : |
|
|
<li>Sparc architecture supported now.</li>
|
| 48 : |
|
|
<li>Support for x86/win32 mostly in place. (All missing pieces are
|
| 49 : |
|
|
in the runtime system.) </li>
|
| 50 : |
|
|
</ul>
|
| 51 : |
|
|
<h4>CM: </h4>
|
| 52 : |
|
|
<ul>
|
| 53 : |
|
|
<li>CM can now generate "index files" which are human-readable files
|
| 54 : |
|
|
that list on a per-.cm-file basis each toplevel symbol defined or imported.</li>
|
| 55 : |
|
|
<li>some internal improvements in the tools subsystem</li>
|
| 56 : |
|
|
<li>"lambdasplit" parameter for class "sml" to control the cross-module
|
| 57 : |
|
|
inliner documented</li>
|
| 58 : |
|
|
<li>other documentation updates</li>
|
| 59 : |
|
|
<li>bug fixes</li>
|
| 60 : |
|
|
</ul>

| 61 : |
|
|
<h4>runtime:</h4>
|
| 62 : |
|
|
<ul>
|
| 63 : |
|
|
<li>A serious signal handling problem that affected CML has been fixed.</li>
|
| 64 : |
|
|
<li>Support for dlopen/dlsym on Sparc/Solaris added. </li>
|
| 65 : |
|
|
</ul>

| 66 : |
|
|
<h4>CML:</h4>
|

|
|
<ul>
|
| 68 : |
|
|
<li>Compiles under the new CM.</li>
|
| 69 : |
|
|
<li>Libraries and anchors for version 110.34 and later are organized
|
| 70 : |
|
|
as follows:</li>

|
<li><b>$cml/cml.cm</b> : Main CML library.</li>

<h4>eXene:</h4>
|
| 81 : |
|
|
<ul>
|
| 82 : |
|
|
<li>Compiles under the new CM.</li>
|
| 83 : |

|
<h4>scripts:</h4>
|
| 86 : |
|
|
<ul>
|
| 87 : |
|
|
<li>The config/install.sh script has been updated to support the installation
|
| 88 : |
|
|
of CML and eXene under the New World Order (aka new CM). </li>
|
| 89 : |
|
|
</ul>

<h4>compiler:</h4>

<li>bug fixes</li>
|
| 93 : |
|
|
<li>cross-module inliner now in the compilation pipeline by default
|
| 94 : |
|
|
<i>(By default it is still turned off. But it can be enabled either
|
| 95 : |
|
|
globally or selectively by using CM's new "lambdasplit" parameter.)</i>

<h4>MLRISC: </h4>

|
| 100 : |
|
|
<li>Sparc implementation of c-calls API. (This is used by NLFFI.)
|
| 101 : |
|
|
<i>(Caveat: Register assignments in the Sparc backend of SML/NJ
|
| 102 : |
|
|
still need to be redone. In particular, the ASM temp register must
|
| 103 : |
|
|
not be %o2. It is unlikely but not impossible that the current situation
|
| 104 : |
|
|
leads to certain subtle code-generation bugs.)</i> </li>
|
| 105 : |
|
|
<li>Support for "stdcall" calling convention in x86 version of c-calls.
