From 70624e1c1d16c2ff3b786ec56ec550f699065741 Mon Sep 17 00:00:00 2001 From: Lioncash Date: Thu, 11 Jul 2019 05:32:50 -0400 Subject: [PATCH] core/arm: Remove obsolete Unicorn memory mapping This was initially necessary when AArch64 JIT emulation was in its infancy and all memory-related instructions weren't implemented. Given the JIT now has all of these facilities implemented, we can remove these functions from the CPU interface. --- src/core/arm/arm_interface.h | 7 ------- src/core/arm/dynarmic/arm_dynarmic.cpp | 9 --------- src/core/arm/dynarmic/arm_dynarmic.h | 3 --- src/core/arm/unicorn/arm_unicorn.cpp | 9 --------- src/core/arm/unicorn/arm_unicorn.h | 3 --- src/core/hle/kernel/vm_manager.cpp | 20 -------------------- 6 files changed, 51 deletions(-) diff --git a/src/core/arm/arm_interface.h b/src/core/arm/arm_interface.h index c6691a8e1..45e94e625 100644 --- a/src/core/arm/arm_interface.h +++ b/src/core/arm/arm_interface.h @@ -44,13 +44,6 @@ public: /// Step CPU by one instruction virtual void Step() = 0;
