Improve GC's marking of seglists #131

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
The GC marks an entire segment even if only some of the entries are valid.  
This can be improved to only mark valid entries; the exact length of the 
seglist.  Can also make it linear rather than recursive for each linked segment.

- Edited src/vm/heap.c heap_gcMarkObj() so that seglists' linked segments are 
marked linearly (not recursive).  The exact number of items are marked. A 
recursive call is still made to mark the segment's items.

System tests pass.
Mainlined directly.
