2015-03-18* gc.c (RGENGC_OLD_NEWOBJ_CHECK): add check mechanism.ko1
If RGENGC_OLD_NEWOBJ_CHECK > 0, then create old objects (not new objects) periodically. Create one old objects per RGENGC_OLD_NEWOBJ_CHECK objects are created. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@50013 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2015-03-18* gc.c (check_rvalue_consistency): refactoring.ko1
* not inline on RGENGC_CHECK_MODE > 0. * check SPECIAL_CONST_P(obj) first. * add a check that remembered_bit is only TRUE when old (age == 3). * gc.c (RVALUE_DEMOTE): should clear RVALUE_REMEMBERED bit. remembered_bit should be TRUE only for old (age == 3) objects. Actually there are no effect because demoted objects will be uncollectible WB unprotected objects (marked at the begginig of every minor GC). git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@50011 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2015-03-18* gc.c: rename terminologies.ko1
* long_lived -> uncollectible: because this bitmap does not mean "long lived objects in past", but means "prohibit collection thse objects until next major GC". Uncollectible objects consist of two types objects, one is old objects (WB protected objects which age == 3) and another is uncollectible WB unprotected objects which are referred from old objects * remembered_wb_unprotected_objects -> uncollectible_wb_unprotected_objects: because uncollectible objects does not mean remembered objects. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@50009 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2015-03-18* gc.c (gc_writebarrier_generational): add an alternative writeko1
barrier (WB) implementation. When finding reference from [Old obj] to [New obj] by WB, current implementation marks [Old obj] as remembered old objects and marks chilldren of [Old obj] at the beggining of marking. Added (but disabled) code changes current behaviour. This fix promote [New obj] to old and marks as a remembered old object. We can assume "new objects referred from old objects are maybe long-lived old objects". Disadvantage of added algorithm is we may promote unwilling short-lived objects. For example, consider many new objects push and pop to an old stack object. All of new objects (short-lived objects) promote to old objects unexpectedly. To compare these behaviour, I add this new code (but disabled it). git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@50006 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2015-03-17* include/ruby/ruby.h: use rb_gc_writebrrier() simply.ko1
For incremental GC, we need to get a pointer to the objspace. We can share this pointer for the following WB process. And considering icache hit ratio, prcess in the GC. * gc.c (rb_gc_writebarrier): added. * gc.c (gc_writebarrier_generational, gc_writebarrier_incremental): make them NOINLINE because inlining them into rb_gc_writebarrier() makes a prologue code of rb_gc_writebarrier() longer (storing callee save registers).

2015-03-17* benchmark/bm_vm1_gc_wb_ary(_promoted).rb: separate fastpath andko1
slowpath for WB. Before this change bm_vm1_gc_wb_ary.rb tried to check the performance for WB slowpath (making a reference from oldobj to newobj). However, from Ruby 2.2, 3 GCs are needed to promote new objects because only 3 age objects are promted objects. To compare fastpath and slowpath, introduce new "promoted" version benchmark. bm_vm1_gc_wb_ary.rb is for fastpath and bm_vm1_gc_wb_ary_promoted.rb is for slowpath. * benchmark/bm_vm1_gc_wb_obj(_promtoed).rb: ditto. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@49985 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
