Slava Pestov 11075828e5 vm: faster data_root and <array> primitive 2009-11-06 05:30:37 -06:00
Slava Pestov e2107166ff vm: restructure data_roots so that its a sequence of handle/len pairs rather than just handles, use it in inline_gc() and all_instances() so that we don't run out of heap while building the object array 2009-11-06 00:54:28 -06:00
