* * vm_insnhelper.c: introduce new call handler for simple ISeqs.ko12015-10-231-0/+72
vm_call_iseq_setup_normal_0start() is simple, however it has some loops/conditions depends on ISeq::param.size and ISeq::local_size (in vm_push_frame(), inlined into this function). There are many simple methods which has a few parameters and local variables. So that this patch introduces several special functions generated in vm_call_iseq_optimized.inc by tool/mk_call_iseq_optimized.rb. This script makes vm_call_iseq_setup_normal_0start_Xparams_Ylocals() where X is 0 to 3 and Y is 1 to 6 (as current setting). In this case, X * Y = 24 functions are created. These functions creates fast method dispatch by inlining vm_push_frame() with immediate params/locals sizes. On my laptop, we can have the following results. vm2_method* 1.083 (8.3% faster) vm2_poly_method* 0.961 (3.4% slower) It shows 8.3% faster for inner loop method dispatch (hit inline cache), but 3.4% slower when inline cache miss because we need to find a suitable call handler. * common.mk: add a rule for vm_call_iseq_optimized.inc. * tool/mk_call_iseq_optimized.rb: added. * vm.c: include vm_call_iseq_optimized.inc. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@52254 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
