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/object.cpp | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) (limited to 'core/object.cpp') diff --git a/core/object.cpp b/core/object.cpp index d86c60a3b8..8c9d3557f8 100644 --- a/core/object.cpp +++ b/core/object.cpp @@ -818,8 +818,8 @@ Variant Object::callv(const StringName &p_method, const Array &p_args) { argptrs.resize(p_args.size()); for (int i = 0; i < p_args.size(); i++) { - args[i] = p_args[i]; - argptrs[i] = &args[i]; + args.write[i] = p_args[i]; + argptrs.write[i] = &args[i]; } Variant::CallError ce; @@ -1182,10 +1182,10 @@ Error Object::emit_signal(const StringName &p_name, const Variant **p_args, int bind_mem.resize(p_argcount + c.binds.size()); for (int j = 0; j < p_argcount; j++) { - bind_mem[j] = p_args[j]; + bind_mem.write[j] = p_args[j]; } for (int j = 0; j < c.binds.size(); j++) { - bind_mem[p_argcount + j] = &c.binds[j]; + bind_mem.write[p_argcount + j] = &c.binds[j]; } args = (const Variant **)bind_mem.ptr(); -- cgit v1.2.3
