From 0e29f7974b59e4440cf02e1388fb9d8ab2b5c5fd Mon Sep 17 00:00:00 2001 From: Hein-Pieter van Braam Date: Wed, 25 Jul 2018 03:11:03 +0200 Subject: Reduce unnecessary COW on Vector by make writing explicit This commit makes operator[] on Vector const and adds a write proxy to it. From now on writes to Vectors need to happen through the .write proxy. So for instance: Vector vec; vec.push_back(10); std::cout << vec[0] << std::endl; vec.write[0] = 20; Failing to use the .write proxy will cause a compilation error. In addition COWable datatypes can now embed a CowData pointer to their data. This means that String, CharString, and VMap no longer use or derive from Vector. _ALWAYS_INLINE_ and _FORCE_INLINE_ are now equivalent for debug and non-debug builds. This is a lot faster for Vector in the editor and while running tests. The reason why this difference used to exist is because force-inlined methods used to give a bad debugging experience. After extensive testing with modern compilers this is no longer the case. --- modules/gdnative/nativescript/nativescript.cpp | 12 ++++++------ 1 file changed, 6 insertions(+), 6 deletions(-) (limited to 'modules/gdnative/nativescript/nativescript.cpp') diff --git a/modules/gdnative/nativescript/nativescript.cpp b/modules/gdnative/nativescript/nativescript.cpp index eb52bede24..3a49b3fe71 100644 --- a/modules/gdnative/nativescript/nativescript.cpp +++ b/modules/gdnative/nativescript/nativescript.cpp @@ -1157,8 +1157,8 @@ int NativeScriptLanguage::register_binding_functions(godot_instance_binding_func } // set the functions - binding_functions[idx].first = true; - binding_functions[idx].second = p_binding_functions; + binding_functions.write[idx].first = true; + binding_functions.write[idx].second = p_binding_functions; return idx; } @@ -1173,7 +1173,7 @@ void NativeScriptLanguage::unregister_binding_functions(int p_idx) { binding_functions[p_idx].second.free_instance_binding_data(binding_functions[p_idx].second.data, binding_data[p_idx]); } - binding_functions[p_idx].first = false; + binding_functions.write[p_idx].first = false; if (binding_functions[p_idx].second.free_func) binding_functions[p_idx].second.free_func(binding_functions[p_idx].second.data); @@ -1199,7 +1199,7 @@ void *NativeScriptLanguage::get_instance_binding_data(int p_idx, Object *p_objec binding_data->resize(p_idx + 1); for (int i = old_size; i <= p_idx; i++) { - (*binding_data)[i] = NULL; + (*binding_data).write[i] = NULL; } } @@ -1208,7 +1208,7 @@ void *NativeScriptLanguage::get_instance_binding_data(int p_idx, Object *p_objec const void *global_type_tag = global_type_tags[p_idx].get(p_object->get_class_name()); // no binding data yet, soooooo alloc new one \o/ - (*binding_data)[p_idx] = binding_functions[p_idx].second.alloc_instance_binding_data(binding_functions[p_idx].second.data, global_type_tag, (godot_object *)p_object); + (*binding_data).write[p_idx] = binding_functions[p_idx].second.alloc_instance_binding_data(binding_functions[p_idx].second.data, global_type_tag, (godot_object *)p_object); } return (*binding_data)[p_idx]; @@ -1221,7 +1221,7 @@ void *NativeScriptLanguage::alloc_instance_binding_data(Object *p_object) { binding_data->resize(binding_functions.size()); for (int i = 0; i < binding_functions.size(); i++) { - (*binding_data)[i] = NULL; + (*binding_data).write[i] = NULL; } binding_instances.insert(binding_data); -- cgit v1.2.3
