From cd76e34056afab83697beef1d1ced94ee671a20d Mon Sep 17 00:00:00 2001 From: Andreas Hansson Date: Mon, 20 Apr 2015 12:46:35 -0400 Subject: cpu: Remove the InOrderCPU from the tree This patch takes the final step in removing the InOrderCPU from the tree. Rest in peace. The MinorCPU is now used to model an in-order microarchitecture, and long term the MinorCPU will eventually be renamed InOrderCPU. --- src/cpu/inorder/resources/tlb_unit.hh | 152 ---------------------------------- 1 file changed, 152 deletions(-) delete mode 100644 src/cpu/inorder/resources/tlb_unit.hh (limited to 'src/cpu/inorder/resources/tlb_unit.hh') diff --git a/src/cpu/inorder/resources/tlb_unit.hh b/src/cpu/inorder/resources/tlb_unit.hh deleted file mode 100644 index 916f67559..000000000 --- a/src/cpu/inorder/resources/tlb_unit.hh +++ /dev/null @@ -1,152 +0,0 @@ -/* - * Copyright (c) 2007 MIPS Technologies, Inc. - * All rights reserved. - * - * Redistribution and use in source and binary forms, with or without - * modification, are permitted provided that the following conditions are - * met: redistributions of source code must retain the above copyright - * notice, this list of conditions and the following disclaimer; - * redistributions in binary form must reproduce the above copyright - * notice, this list of conditions and the following disclaimer in the - * documentation and/or other materials provided with the distribution; - * neither the name of the copyright holders nor the names of its - * contributors may be used to endorse or promote products derived from - * this software without specific prior written permission. - * - * THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS - * "AS IS" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT - * LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR - * A PARTICULAR PURPOSE ARE DISCLAIMED.
