<h4> x86 </h4>
|
| 43 : |
|

All back ends now directly generate the sqrt instruction, and the Intel
|
| 44 : |
|
|
x86 also generate the trig instructions to implement sine, cosine, and
|
| 45 : |
|
|
tangent.

The ICFP00, PCLubIN entry shows a significant improvement as a result
|
| 48 : |
|
|
(most of it coming from fsqrt).

|
|
<h4>Changes to scripts</h4>
|
| 71 : |
|
|
<ul>
|
| 72 : |
|
|
<li> "ml-build" for generating standalone programs
|
| 73 : |
|
|
<li> "ml-makedepend" (new!) for generating Makefile dependencies
|
| 74 : |
|
|
(not generally required but some project might want them)
|
| 75 : |
|
|
<li> "sml" - the main driver script for running SML/NJ.
|
| 76 : |
|
|
</ul>
|
| 77 : |
|
|
<p>
|
| 78 : |
|
|
<blockquote>
|
| 79 : |
|
|
All these scripts now accept more CM-related command-line options.
|
| 80 : |
|
|
<p>
|
| 81 : |
|
|
ml-build is faster and cleverer in avoiding unnecessary work.
|
| 82 : |
|
|
</blockquote>
|
| 83 : |
|
|
|
| 84 : |
|
|
<h4>Other Changes</h4>
|
| 85 : |
|
|
Type of CM.mk_standalone has changed.
|
| 86 : |
|
|
<p>
|
| 87 : |
|
|
All user-visible changes to CM (including the above-mentioned scripts)
|
| 88 : |
|
|
are documented in the CM manual. Some errors and omissions have been
|
| 89 : |
|
|
corrected as well.
|
| 90 : |
|
|
<p>
|
| 91 : |
|
|
Bug fixes to CM's internals (e.g., missing or repeated error messages).
|
| 92 : |
|
|
<p>
|
| 93 : |
|
|
Pickling/Unpickling improvements result in faster autoloading and
|
| 94 : |
|
|
reduce resident memory size.

|
|
<center><h3>CMB</h3></center>
|
| 98 : |
|
|
Conditional compilation within the "init library".
|
| 99 : |
|
|
(One can now use "ifdef" and "ifndef" guards in init.cmi.
|
| 100 : |
|
|
This is documented in the long comment at the beginning of
|
| 101 : |
|
|
that file (src/system/smlnj/init/init.cmi).)
