From eb36d3fc903db8848f7493009c7b59c8ce038de9 Mon Sep 17 00:00:00 2001 From: bunnei Date: Fri, 29 Aug 2014 23:24:32 -0400 Subject: Core: Refactor core to use only one function for execution. Core: Cleaned up comment to be more readable. Citra: Changed loop to be more readable. --- src/citra/citra.cpp | 4 +++- src/core/core.cpp | 26 ++++++++------------------ src/core/core.h | 11 +++++++++-- 3 files changed, 20 insertions(+), 21 deletions(-) diff --git a/src/citra/citra.cpp b/src/citra/citra.cpp index 9399ff29..7dc721dc 100644 --- a/src/citra/citra.cpp +++ b/src/citra/citra.cpp @@ -31,7 +31,9 @@ int __cdecl main(int argc, char **argv) { return -1; } - Core::RunLoop(); + while(true) { + Core::RunLoop(); + } delete emu_window; diff --git a/src/core/core.cpp b/src/core/core.cpp index fc990937..f21801e5 100644 --- a/src/core/core.cpp +++ b/src/core/core.cpp @@ -6,6 +6,8 @@ #include "common/log.h" #include "common/symbols.h" +#include "video_core/video_core.h" + #include "core/core.h" #include "core/mem_map.h" #include "core/hw/hw.h" @@ -24,29 +26,17 @@ ARM_Interface* g_app_core = nullptr; ///< ARM11 application core ARM_Interface* g_sys_core = nullptr; ///< ARM11 system (OS) core /// Run the core CPU loop -void RunLoop() { - for (;;){ - // This function loops for 100 instructions in the CPU before trying to update hardware. - // This is a little bit faster than SingleStep, and should be pretty much equivalent.
