[movitz-announce] Bignums have landed..

..but we still need to tax to the terminal building. That is, this is to announce that I now consider Movitz to support bignums reasonably well. However, there's bound to be some bignums bugs still, and certainly there are arithmetic operators that don't yet support bignums (not to mention operators that are missing completely). -- Frode Vatvedt Fjeld

[movitz-announce] Movitz has new 'basic-vectors' data-structure, and improved GC.
by Frode Vatvedt Fjeld 08 Jul '04

I've just checked in the last pieces of the migration to a new data-structure for vectors, called "basic-vectors". The most important new feature is that the vector's length is now a fixnum, so that vectors are now restricted to most-positive-fixnum (#x1fffffff) rather than the old limit of #xffff. One practical consequence of this, is that the example GC implementation in los0-gc.lisp is now capable of supporting new-spaces up to size 2 GB. However, I believe the practically useful range is going to be below a few tens of MB. I've set the default size to 2 MB. There have also been numerous bug-fixes. A new los0.img is being uploaded to the clnet web-site. -- Frode Vatvedt Fjeld
