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. --- core/script_debugger_remote.cpp | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) (limited to 'core/script_debugger_remote.cpp') diff --git a/core/script_debugger_remote.cpp b/core/script_debugger_remote.cpp index 3955f222f9..c5daaeea47 100644 --- a/core/script_debugger_remote.cpp +++ b/core/script_debugger_remote.cpp @@ -783,13 +783,13 @@ void ScriptDebuggerRemote::_send_profiling_data(bool p_for_frame) { for (int i = 0; i < ScriptServer::get_language_count(); i++) { if (p_for_frame) - ofs += ScriptServer::get_language(i)->profiling_get_frame_data(&profile_info[ofs], profile_info.size() - ofs); + ofs += ScriptServer::get_language(i)->profiling_get_frame_data(&profile_info.write[ofs], profile_info.size() - ofs); else - ofs += ScriptServer::get_language(i)->profiling_get_accumulated_data(&profile_info[ofs], profile_info.size() - ofs); + ofs += ScriptServer::get_language(i)->profiling_get_accumulated_data(&profile_info.write[ofs], profile_info.size() - ofs); } for (int i = 0; i < ofs; i++) { - profile_info_ptrs[i] = &profile_info[i]; + profile_info_ptrs.write[i] = &profile_info.write[i]; } SortArray sa; @@ -1054,7 +1054,7 @@ void ScriptDebuggerRemote::add_profiling_frame_data(const StringName &p_name, co if (idx == -1) { profile_frame_data.push_back(fd); } else { - profile_frame_data[idx] = fd; + profile_frame_data.write[idx] = fd; } } -- cgit v1.2.3
