Takashi Kokubun 37a2e48d76 Avoid generating opt_send with cfunc cc with JIT ... only for opt_nil_p and opt_not. While vm_method_cfunc_is is used for opt_eq too, many fast paths of it don't call it. So if it's populated, it should generate opt_send, regardless of cfunc or not. And again, opt_neq isn't relevant due to the difference in operands. So opt_nil_p and opt_not are the only variants using vm_method_cfunc_is like they use. ``` $ benchmark-driver -v --rbenv 'before2 --jit::ruby --jit;before --jit;after --jit' benchmark/mjit_opt_cc_insns.yml --repeat-count=4 before2 --jit: ruby 2.8.0dev (2020-06-22T08:37:37Z master 3238641750) +JIT [x86_64-linux] before --jit: ruby 2.8.0dev (2020-06-23T01:01:24Z master 9ce2066209) +JIT [x86_64-linux] after --jit: ruby 2.8.0dev (2020-06-23T06:58:37Z master 17e9df3157) +JIT [x86_64-linux] last_commit=Avoid generating opt_send with cfunc cc with JIT Calculating ------------------------------------- before2 --jit before --jit after --jit mjit_nil?(1) 54.204M 75.536M 75.031M i/s - 40.000M times in 0.737947s 0.529548s 0.533110s mjit_not(1) 53.822M 70.921M 71.920M i/s - 40.000M times in 0.743195s 0.564007s 0.556171s mjit_eq(1, nil) 7.367M 6.496M 7.331M i/s - 8.000M times in 1.085882s 1.231470s 1.091327s Comparison: mjit_nil?(1) before --jit: 75536059.3 i/s after --jit: 75031409.4 i/s - 1.01x slower before2 --jit: 54204431.6 i/s - 1.39x slower mjit_not(1) after --jit: 71920324.1 i/s before --jit: 70921063.1 i/s - 1.01x slower before2 --jit: 53821697.6 i/s - 1.34x slower mjit_eq(1, nil) before2 --jit: 7367280.0 i/s after --jit: 7330527.4 i/s - 1.01x slower before --jit: 6496302.8 i/s - 1.13x slower ```		2020-06-23 00:09:54 -07:00
