2017-07-27Embed small size array elements in the heap.Yukihiro "Matz" Matsumoto
It reduces the memory consumption and sometimes improve the performance as well. For example, the consumed memory size of `bench/bm_ao_render.rb` is reduced from 1.2GB to 1GB, and its total execution time become 18.795 sec from 22.229 sec.
2017-07-18Simplify `mrb_gc_arena_restore()` to reduce overhead.Yukihiro "Matz" Matsumoto
It will no longer shrink arena region. Instead `vm.c` uses a static function `mrb_gc_arena_shrink()` to shrink.
2017-07-12Avoid float operation to shrink arena buffer size.Yukihiro "Matz" Matsumoto
2017-06-22No need to mark stacks of terminated fibers; fix #3720Yukihiro "Matz" Matsumoto
2017-06-17Merge pull request #3706 from MasahikoSawada/fix_typoYukihiro "Matz" Matsumoto
Fix a typo in gc.c.
2017-06-17Mark the GC arena in `final_marking_phase`.Yukihiro "Matz" Matsumoto
Arena can be modified during the marking phase.
2017-06-17Mark the root context in `final_marking_phase`.Yukihiro "Matz" Matsumoto
Because the root context cannot be marked from fibers.
2017-06-17Mark global variables in `final_marking_phase`; fix #3704Yukihiro "Matz" Matsumoto
2017-06-17Correct comments in gc.cYukihiro "Matz" Matsumoto

2017-06-16Allow `break` from a block called by `mrb_yield`; close #3359Yukihiro "Matz" Matsumoto
This means #3701 is now OK to merge.
2017-06-16Use `MRB_THROW` instead of `mrb_exc_raise`.Yukihiro "Matz" Matsumoto
2017-06-15Mark the exception object in the final marking phase; ref #3702Yukihiro "Matz" Matsumoto

2017-05-25Revert 01f7825; fix #3650Yukihiro "Matz" Matsumoto
Redundant `mark_context() is far better than crashes.
2017-05-25Avoid marking possibly freed stack; #3550 #3612Yukihiro "Matz" Matsumoto
2017-05-23Simplify backtrace mechanism; fix #3633 #3634 #3644Yukihiro "Matz" Matsumoto
Instead of preserving a backtrace in `mrb_state`, `mrb_exc_set` keeps packed backtrace in an exception object. `#backtrace` unpacks it to an array of strings.

2017-05-23Use index in `each_object`.Yukihiro "Matz" Matsumoto

This reverts commit d2cad9ac5b8db89fc9d21f5795846f983236798c.
2017-04-25Use fiber marking instead of `mark_context`.Yukihiro "Matz" Matsumoto
