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/gdscript/gdscript_functions.cpp | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'modules/gdscript/gdscript_functions.cpp') diff --git a/modules/gdscript/gdscript_functions.cpp b/modules/gdscript/gdscript_functions.cpp index 7e98b6ced9..63286b2e91 100644 --- a/modules/gdscript/gdscript_functions.cpp +++ b/modules/gdscript/gdscript_functions.cpp @@ -1098,7 +1098,7 @@ void GDScriptFunctions::call(Function p_func, const Variant **p_args, int p_arg_ for (Map::Element *E = gd_ref->member_indices.front(); E; E = E->next()) { if (d.has(E->key())) { - ins->members[E->get().index] = d[E->key()]; + ins->members.write[E->get().index] = d[E->key()]; } } -- cgit v1.2.3
