Slava Pestov 86da8ebed9 Instead of bumping the definition counter every time in the VM, bump it only if stack effects changed or macros were redefined 2009-11-13 03:52:14 -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 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 21f55ab1a3 vm: more efficient code heap remembered set 2009-10-08 23:10:32 -05:00

Slava Pestov 697e2342d0 vm: put code block owner directly in the header, instead of as the first entry in the literal table. Reduces x86-64 image size by ~700kb, also eliminates separate 'strip' set of staging images from deploy tool 2009-10-06 06:25:07 -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
