+ * benchmark/bm_vm1_gc_wb_ary(_promoted).rb: separate fastpath and
+ 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.
