Slava Pestov 4061951d1c vm: simpler object space implementation. begin-scan/next-object/end-scan primitives replaced by a single all-instances primitive 2009-11-05 21:49:03 -06:00
Slava Pestov 6c2c87758a vm: rename gc_root to data_root, add code_root to fix a problem where code blocks would move underneath the PIC compiler if PIC compiler allocated enough 2009-11-02 18:10:34 -06:00

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 b50d3f3fb0 vm: number of generations is not configurable anymore, split up begin_gc() and end_gc() into collect_{nursery,aging,aging_again,tenured}() 2009-10-06 02:39:12 -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
