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/bullet/shape_bullet.cpp | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'modules/bullet/shape_bullet.cpp') diff --git a/modules/bullet/shape_bullet.cpp b/modules/bullet/shape_bullet.cpp index 92e7c2df98..e4c1a5f9b5 100644 --- a/modules/bullet/shape_bullet.cpp +++ b/modules/bullet/shape_bullet.cpp @@ -304,7 +304,7 @@ void ConvexPolygonShapeBullet::get_vertices(Vector &out_vertices) { const int n_of_vertices = vertices.size(); out_vertices.resize(n_of_vertices); for (int i = n_of_vertices - 1; 0 <= i; --i) { - B_TO_G(vertices[i], out_vertices[i]); + B_TO_G(vertices[i], out_vertices.write[i]); } } -- cgit v1.2.3
