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. --- drivers/wasapi/audio_driver_wasapi.cpp | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'drivers/wasapi') diff --git a/drivers/wasapi/audio_driver_wasapi.cpp b/drivers/wasapi/audio_driver_wasapi.cpp index 1d96f9ee7d..5982955c4f 100644 --- a/drivers/wasapi/audio_driver_wasapi.cpp +++ b/drivers/wasapi/audio_driver_wasapi.cpp @@ -447,7 +447,7 @@ void AudioDriverWASAPI::thread_func(void *p_udata) { ad->audio_server_process(ad->buffer_frames, ad->samples_in.ptrw()); } else { for (unsigned int i = 0; i < ad->buffer_size; i++) { - ad->samples_in[i] = 0; + ad->samples_in.write[i] = 0; } } -- cgit v1.2.3
