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/mono/mono_gd/gd_mono.cpp | 4 ++-- modules/mono/mono_gd/gd_mono_class.cpp | 2 +- 2 files changed, 3 insertions(+), 3 deletions(-) (limited to 'modules/mono/mono_gd') diff --git a/modules/mono/mono_gd/gd_mono.cpp b/modules/mono/mono_gd/gd_mono.cpp index 0f4e211be5..f564b93f8f 100644 --- a/modules/mono/mono_gd/gd_mono.cpp +++ b/modules/mono/mono_gd/gd_mono.cpp @@ -77,12 +77,12 @@ void setup_runtime_main_args() { Vector main_args; main_args.resize(cmdline_args.size() + 1); - main_args[0] = execpath.ptrw(); + main_args.write[0] = execpath.ptrw(); int i = 1; for (List::Element *E = cmdline_args.front(); E; E = E->next()) { CharString &stored = cmdline_args_utf8.push_back(E->get().utf8())->get(); - main_args[i] = stored.ptrw(); + main_args.write[i] = stored.ptrw(); i++; } diff --git a/modules/mono/mono_gd/gd_mono_class.cpp b/modules/mono/mono_gd/gd_mono_class.cpp index 53d6b7074c..ad74f73d74 100644 --- a/modules/mono/mono_gd/gd_mono_class.cpp +++ b/modules/mono/mono_gd/gd_mono_class.cpp @@ -503,7 +503,7 @@ GDMonoClass::~GDMonoClass() { } } - deleted_methods[offset] = method; + deleted_methods.write[offset] = method; ++offset; memdelete(method); -- cgit v1.2.3
