Abdulaziz Ghuloum cee16e7463 Fixes bug 176816: Incorrect &who for open-output-file 2007-12-18 03:32:07 -05:00
Abdulaziz Ghuloum bbe388656c fixes bug 176756: define-condition-type does not work in repl 2007-12-17 11:37:10 -05:00
Abdulaziz Ghuloum 64c20409ce made read-char just as efficient as get-char by copy&paste. 2007-12-15 11:43:04 -05:00
Abdulaziz Ghuloum 372c3e369b Change of strategy in the garbage collector.
Previously: when a generation (say 2) is collected, 
  everything in gen 0 moves to gen 1
  everything in gen 1 moves to gen 2
  everything in gen 2 moves to gen 3

Now: when a generation (say 2 again) is collected
  everything in gen 0 moves to gen 3
  everything in gen 1 moves to gen 3
  everything in gen 2 moves to gen 3

So, some objects get a leap from young to old if they're lucky to be
in the right time.

Consequences: when an object is moved by the collector, we don't
need to track old->new pointers and masks because all moved objects
are clean now.  This both simplifies the collector and makes it more
efficient and might open the door for further optimization
opportunities.  For bootstrap time, we get about 5% overall 
saving and about 20% GC-time saving.  Not bad.

BEFORE:
running stats for macro expansion:
    45 collections
    2558 ms elapsed cpu time, including 212 ms collecting
    2576 ms elapsed real time, including 216 ms collecting

Abdulaziz Ghuloum 5a98c9e460 changed error message as suggested in bug 173369. 2007-12-15 09:00:31 -05:00
Abdulaziz Ghuloum c1a677ca4b Changed implementation of append so that it uses half the cons cells
that it previously used.  Interestingly, this reduced bootstrap time
by 60ms and 2 garbage collections!  And I thought I did not use
append :-).
