2017-12-05	arm: Add support for the dc {civac, cvac, cvau, ivac} instr	Nikos Nikoleris
	This patch adds support for decoding and executing the following ARMv8 cache maintenance instructions by Virtual Address: * dc civac: Clean and Invalidate by Virtual Address to the Point of Coherency * dc cvac: Clean by Virtual Address to the Point of Coherency * dc cvau: Clean by Virtual Address to the Point of Unification * dc ivac: Invalidate by Virtual Addrsess to the Point of Coherency Change-Id: I58cabda37f9636105fda1b1e84a0a04965fb5670 Reviewed-by: Sudhanshu Jha <sudhanshu.jha@arm.com> Reviewed-by: Stephan Diestelhorst <stephan.diestelhorst@arm.com> Reviewed-on: https://gem5-review.googlesource.com/5060 Maintainer: Andreas Sandberg <andreas.sandberg@arm.com> Reviewed-by: Andreas Sandberg <andreas.sandberg@arm.com>
2014-11-14	arm: Fixes based on UBSan and static analysis	Andreas Hansson
	Another churn to clean up undefined behaviour, mostly ARM, but some parts also touching the generic part of the code base. Most of the fixes are simply ensuring that proper intialisation. One of the more subtle changes is the return type of the sign-extension, which is changed to uint64_t. This is to avoid shifting negative values (undefined behaviour) in the ISA code.
2014-01-24	arm: Add support for ARMv8 (AArch64 & AArch32)	ARM gem5 Developers
	Note: AArch64 and AArch32 interworking is not supported. If you use an AArch64 kernel you are restricted to AArch64 user-mode binaries. This will be addressed in a later patch. Note: Virtualization is only supported in AArch32 mode. This will also be fixed in a later patch.
