Joe Groff e56f2b5753 vm: replace remaining stack_frame-based logic 2011-12-14 09:56:49 -08:00
Joe Groff 9df2c107dc vm: remove _reversed from callstack iterator names 
Now that they're the only game in town we can give them the short names

Joe Groff 099559c191 remove iterate_callstack now that it's unused 2011-12-14 09:56:48 -08:00
Joe Groff 841600fc6e vm: stage code block map fixup properly for GC 
Don't update the map until the very last thing, and pass untranslated addresses to the iterator functors. Somewhat complicated by the fact that, for startup_fixup, the map is initialized with fixed-up values, so the fixup functor needs a flag indicating whether it operates with a fixed or unfixed code heap map.

Joe Groff 5926257d1e WIP verify_callstack function 
dumps callstack in reverse order so i can visually inspect that it matches the old forward walking logic

Slava Pestov adeb6fb68f vm: actually use context callstacks when running code 2010-03-26 22:44:43 -04:00
Slava Pestov a942e2c34d vm: eliminating register variables work in progress. Works on x86-32 with non-optimizing compiler 2009-12-19 10:59:56 +13:00
Slava Pestov 31a260b74c vm: big overhaul of non-optimizing compiler 
- change some primitives into sub-primitives: fixnum+ fixnum- fixnum* inline-cache-miss inline-cache-miss-tail
- rename some relocation types for clarity
- some other minor re-organizations and cleanups

Slava Pestov b341527428 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 7c126be62b vm: simpler and more efficient code heap compaction; restructure a few things to get ready for runtime code heap compaction 2009-10-16 04:33:35 -05:00
Slava Pestov 3887292543 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
