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/gdnative.cpp | 10 +++++----- 1 file changed, 5 insertions(+), 5 deletions(-) (limited to 'modules/gdnative/gdnative.cpp') diff --git a/modules/gdnative/gdnative.cpp b/modules/gdnative/gdnative.cpp index e7ebcc73af..0acd6c27d8 100644 --- a/modules/gdnative/gdnative.cpp +++ b/modules/gdnative/gdnative.cpp @@ -277,7 +277,7 @@ void GDNative::set_library(Ref p_library) { library = p_library; } -Ref GDNative::get_library() { +Ref GDNative::get_library() const { return library; } @@ -373,7 +373,7 @@ bool GDNative::initialize() { if (library->should_load_once() && !GDNativeLibrary::loaded_libraries->has(lib_path)) { Vector > gdnatives; gdnatives.resize(1); - gdnatives[0] = Ref(this); + gdnatives.write[0] = Ref(this); GDNativeLibrary::loaded_libraries->insert(lib_path, gdnatives); } @@ -428,7 +428,7 @@ bool GDNative::terminate() { return true; } -bool GDNative::is_initialized() { +bool GDNative::is_initialized() const { return initialized; } @@ -442,7 +442,7 @@ Vector GDNativeCallRegistry::get_native_call_types() { size_t idx = 0; for (Map::Element *E = native_calls.front(); E; E = E->next(), idx++) { - call_types[idx] = E->key(); + call_types.write[idx] = E->key(); } return call_types; @@ -474,7 +474,7 @@ Variant GDNative::call_native(StringName p_native_call_type, StringName p_proced return res; } -Error GDNative::get_symbol(StringName p_procedure_name, void *&r_handle, bool p_optional) { +Error GDNative::get_symbol(StringName p_procedure_name, void *&r_handle, bool p_optional) const { if (!initialized) { ERR_PRINT("No valid library handle, can't get symbol from GDNative object"); -- cgit v1.2.3
