| | | | | | | | | | | | | | | * 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.

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

* * gc.c (gc_writebarrier_generational): add an alternative writeko12015-03-182-3/+41
| | | | | | | | | | | | | | | | | | | | 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

| | | | | | | | | | | | | | | | | | | | | | 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).

| | | | | | | | | | | | | | | | | 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
