From 985087c7e2e17e66eb4e4bb7f70ab25a4a86c838 Mon Sep 17 00:00:00 2001 From: magumagu Date: Wed, 11 Feb 2015 21:49:53 -0800 Subject: [PATCH] Make all unknown opcodes behave consistently. Consistently fall back to the interpreter for unknown instructions, and make sure GetOpInfo() always returns a non-null pointer. --- .../Interpreter/Interpreter_Tables.cpp | 26 +++++++++---------- Source/Core/Core/PowerPC/Jit64/Jit.cpp | 5 ---- Source/Core/Core/PowerPC/Jit64/Jit.h | 1 - .../Core/Core/PowerPC/Jit64/Jit64_Tables.cpp | 10 +++---- Source/Core/Core/PowerPC/Jit64IL/JitIL.cpp | 6 ----- Source/Core/Core/PowerPC/Jit64IL/JitIL.h | 1 - .../Core/PowerPC/Jit64IL/JitIL_Tables.cpp | 10 +++---- Source/Core/Core/PowerPC/JitArm32/Jit.cpp | 4 --- Source/Core/Core/PowerPC/JitArm32/Jit.h | 1 - .../Core/PowerPC/JitArm32/JitArm_Tables.cpp | 10 +++---- Source/Core/Core/PowerPC/JitArm64/Jit.cpp | 5 ---- Source/Core/Core/PowerPC/JitArm64/Jit.h | 1 - .../Core/PowerPC/JitArm64/JitArm64_Tables.cpp | 10 +++---- .../Core/Core/PowerPC/JitILCommon/JitILBase.h | 1 - Source/Core/Core/PowerPC/PPCAnalyst.cpp | 5 ---- 15 files changed, 33 insertions(+), 63 deletions(-) diff --git a/Source/Core/Core/PowerPC/Interpreter/Interpreter_Tables.cpp b/Source/Core/Core/PowerPC/Interpreter/Interpreter_Tables.cpp index fb7275f9a6..c8c16a6640 100644 --- a/Source/Core/Core/PowerPC/Interpreter/Interpreter_Tables.cpp +++ b/Source/Core/Core/PowerPC/Interpreter/Interpreter_Tables.cpp @@ -13,6 +13,8 @@ struct GekkoOPTemplate GekkoOPInfo opinfo;
