Slava Pestov 344c357ef1 vm: grow the heap if a full collection doesn't reclaim enough space 2009-12-05 19:03:53 -05:00
Slava Pestov 72ab6ec548 vm: rewrite 'become' primitive so that it uses a slot visitor instead of GC 2009-11-05 19:03:51 -06:00
Slava Pestov e1c365e69a vm: fix issue with unnecessary heap growth 2009-11-03 22:25:22 -06:00

Slava Pestov 5536003cf8 vm: new GC policy: mark sweep after N megabytes promoted, mark compact if tenured space cannot fit nursery+aging in one contiguous block. N = 32 on 32-bit and 64 on 64-bit 2009-10-30 02:26:57 -05:00

Slava Pestov e482940dca vm: object start recording in cards is now independent of allocation strategy 2009-10-20 13:47:04 -05:00
Slava Pestov d22d5466fc vm: move factor_vm::untagged_object_size() to object::size() 2009-10-20 13:13:39 -05:00
Slava Pestov 45eb68fa38 vm: during tenuring stage of aging collection, if tenured space fills up, it would attempt a to_tenured collection. this will succeed if all roots were tenured. however, this is unsound, because there's now an untraced segment of tenured space. fix: if tenuring fails, go on to do a full collection instead 2009-10-15 05:51:11 -05:00

Slava Pestov bae2240f62 vm: refactoring garbage collector 2009-10-05 22:16:08 -05:00
Slava Pestov c4ef640f4d Big VM cleanup
- Move forward declarations of 'struct factor_vm' to one place
- Rename template parameters from T and TYPE to descriptive names. New convention: CamelCase for template parameters
- Change some higher-order functions taking function pointers into templates, and define classes overriding operator(). There's a bit of new boilerplate here but its more consistent than the old mish-mash approaches
- Put GC state into a gc_state struct
- Use exceptions instead of longjmp for non-local control transfer in GC
- In code GC, instead of interleaving code block tracing with copying, add code blocks which need to be revisited to an std::set stored in the gc_state
