From f6e9452b23e4aeb84c2c3cd12eaa10d802115fa6 Mon Sep 17 00:00:00 2001 From: ko1 Date: Tue, 17 Mar 2015 09:57:47 +0000 Subject: * 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. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@49985 b2dd03c8-39d4-4d8f-98ff-823fe69b080e --- ChangeLog | 18 ++++++++++++++++++ 1 file changed, 18 insertions(+) (limited to 'ChangeLog') diff --git a/ChangeLog b/ChangeLog index 7edc05d845..0d972bef79 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,21 @@ +Tue Mar 17 18:51:43 2015 Koichi Sasada + + * 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).
