From 25ffa8eb8b3ebdfe62f1e17f51030ffdf79b5275 Mon Sep 17 00:00:00 2001 From: Gabe Black Date: Mon, 23 Aug 2010 16:14:24 -0700 Subject: X86: Create a directory for files that define register indexes. This is to help tidy up arch/x86. These files should not be used external to the ISA. --HG-- rename : src/arch/x86/apicregs.hh => src/arch/x86/regs/apic.hh rename : src/arch/x86/floatregs.hh => src/arch/x86/regs/float.hh rename : src/arch/x86/intregs.hh => src/arch/x86/regs/int.hh rename : src/arch/x86/miscregs.hh => src/arch/x86/regs/misc.hh rename : src/arch/x86/segmentregs.hh => src/arch/x86/regs/segment.hh --- src/arch/x86/regs/segment.hh | 68 ++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 68 insertions(+) create mode 100644 src/arch/x86/regs/segment.hh (limited to 'src/arch/x86/regs/segment.hh') diff --git a/src/arch/x86/regs/segment.hh b/src/arch/x86/regs/segment.hh new file mode 100644 index 000000000..737934152 --- /dev/null +++ b/src/arch/x86/regs/segment.hh @@ -0,0 +1,68 @@ +/* + * Copyright (c) 2007 The Hewlett-Packard Development Company + * All rights reserved. + * + * The license below extends only to copyright in the software and shall + * not be construed as granting a license to any other intellectual + * property including but not limited to intellectual property relating + * to a hardware implementation of the functionality of the software + * licensed hereunder.
