From 818ba32746072af65a7b5ac0f1712bde3388f641 Mon Sep 17 00:00:00 2001 From: bunnei Date: Tue, 7 Oct 2014 18:56:40 -0400 Subject: ARM: Removed unnecessary and unused SkyEye MMU code. Added license header back in. I originally removed this because I mostly rewrote the file, but meh --- src/core/arm/interpreter/armmmu.cpp | 238 ------------------------------------ 1 file changed, 238 deletions(-) delete mode 100644 src/core/arm/interpreter/armmmu.cpp (limited to 'src/core/arm/interpreter/armmmu.cpp') diff --git a/src/core/arm/interpreter/armmmu.cpp b/src/core/arm/interpreter/armmmu.cpp deleted file mode 100644 index 98fc17ddb..000000000 --- a/src/core/arm/interpreter/armmmu.cpp +++ /dev/null @@ -1,238 +0,0 @@ -/* - armmmu.c - Memory Management Unit emulation. - ARMulator extensions for the ARM7100 family. - Copyright (C) 1999 Ben Williamson - - This program is free software; you can redistribute it and/or modify - it under the terms of the GNU General Public License as published by - the Free Software Foundation; either version 2 of the License, or - (at your option) any later version. - - This program is distributed in the hope that it will be useful, - but WITHOUT ANY WARRANTY; without even the implied warranty of - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
