From 5bc4eabe36b7ef4dcd5ad8db1e944705655be432 Mon Sep 17 00:00:00 2001 From: Lioncash Date: Fri, 27 Nov 2020 10:50:48 -0500 Subject: core: Eliminate remaining usages of the global system instance Removes all remaining usages of the global system instance. After this, migration can begin to migrate to being constructed and managed entirely by the various frontends. --- src/core/CMakeLists.txt | 2 - src/core/arm/dynarmic/arm_dynarmic_64.cpp | 11 - src/core/core.cpp | 7 +- src/core/cpu_manager.cpp | 1 - src/core/gdbstub/gdbstub.cpp | 1397 ----------------------- src/core/gdbstub/gdbstub.h | 114 -- src/core/loader/deconstructed_rom_directory.cpp | 3 - src/core/loader/kip.cpp | 3 - src/core/loader/nro.cpp | 6 +- src/core/loader/nso.cpp | 5 +- src/core/settings.cpp | 17 +- src/core/settings.h | 8 +- 12 files changed, 16 insertions(+), 1558 deletions(-) delete mode 100644 src/core/gdbstub/gdbstub.cpp delete mode 100644 src/core/gdbstub/gdbstub.h (limited to 'src/core') diff --git a/src/core/CMakeLists.txt b/src/core/CMakeLists.txt index e370fd225..66de33799 100644 --- a/src/core/CMakeLists.txt +++ b/src/core/CMakeLists.txt @@ -135,8 +135,6 @@ add_library(core STATIC frontend/framebuffer_layout.cpp frontend/framebuffer_layout.h frontend/input.h - gdbstub/gdbstub.cpp - gdbstub/gdbstub.h hardware_interrupt_manager.cpp hardware_interrupt_manager.h hle/ipc.h diff --git a/src/core/arm/dynarmic/arm_dynarmic_64.cpp b/src/core/arm/dynarmic/arm_dynarmic_64.cpp index 9f170a224..5c2060d78 100644 --- a/src/core/arm/dynarmic/arm_dynarmic_64.cpp +++ b/src/core/arm/dynarmic/arm_dynarmic_64.cpp @@ -14,7 +14,6 @@ #include "core/arm/dynarmic/arm_exclusive_monitor.h" #include "core/core.h" #include "core/core_timing.h" -#include "core/gdbstub/gdbstub.h" #include "core/hardware_properties.h" #include "core/hle/kernel/process.h" #include "core/hle/kernel/scheduler.h" @@ -96,16 +95,6 @@ public: case Dynarmic::A64::Exception::Yield: return;
