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. --- editor/project_manager.cpp | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'editor/project_manager.cpp') diff --git a/editor/project_manager.cpp b/editor/project_manager.cpp index af7c4bb379..95d39953cf 100644 --- a/editor/project_manager.cpp +++ b/editor/project_manager.cpp @@ -1781,8 +1781,8 @@ ProjectManager::ProjectManager() { vb->add_constant_override("separation", 15 * EDSCALE); String cp; - cp.push_back(0xA9); - cp.push_back(0); + cp += 0xA9; + cp += '0'; OS::get_singleton()->set_window_title(VERSION_NAME + String(" - ") + TTR("Project Manager") + " - " + cp + " 2007-2018 Juan Linietsky, Ariel Manzur & Godot Contributors"); HBoxContainer *top_hb = memnew(HBoxContainer); -- cgit v1.2.3
