!!!! NEW BOOT FILES !!!! |
| 21 |
|

|
* The main purpose of this update is to make library pickles lazier in |
| 23 |
|
order to reduce the initial space penalty for autoloading a library. |
| 24 |
|
As a result, it is now possible to have $smlnj/compiler.cm |
| 25 |
|
pre-registered. This should take care of the many complaints or |
| 26 |
|
inquiries about missing structure Compiler. This required changes to |
| 27 |
|
CM's internal data structures and small tweaks to some algorithms. |
| 28 |
|
|
| 29 |
|
As a neat additional effect, it is no longer necessary (for the sake |
| 30 |
|
of lean heap image files) to distinguish between a "minimal" CM and a |
| 31 |
|
"full" CM. Now, there is only one CM (i.e., the "full" version: |
| 32 |
|
$smlnj/cm.cm aka $smlnj/cm/full.cm), and it is always available at the |
| 33 |
|
interactive top level. ($smlnj/cm/minimal.cm is gone.) |
| 34 |
|
|
| 35 |
|
To make the life of compiler-hackers easier, "makeml" now also |
| 36 |
|
pre-registers $smlnj/cmb.cm (aka $smlnj/cmb/current.cm). In other |
| 37 |
|
words, after you bootstrap a new sml for the first time, you will not |
| 38 |
|
have to autoload $smlnj/cmb.cm again afterwards. (The first time |
| 39 |
|
around you will still have to do it, though.) |
| 40 |
|
|
| 41 |
|
* A second change consists of major updates to the CM manual. There |
| 42 |
|
are now several appendices with summary information and also a full |
| 43 |
|
specification of the CM description file syntax. |
| 44 |
|
|
| 45 |
|
* In directory src/system I added the script "allcross". This script |
| 46 |
|
invokes sml and cross-compiles the compiler for all supported |
| 47 |
|
architectures. (Useful when providing a new set of boot files.) |
| 48 |
|
|
| 49 |
|
* There seems to be a latent bug in my "lazy pickles" mechanism. I |
| 50 |
|
added a small tweak to pickle-util.sml to work around this problem, |
| 51 |
|
but it is not a proper fix yet. I will investigate further. (The |
| 52 |
|
effect of the bug was an inflation of library pickle size.) |
| 53 |
|
|
| 54 |
|
* Version number increased to 110.28.1 (to avoid compatibility problems). |
