2014-11-14arm: Fixes based on UBSan and static analysisAndreas 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.
2014-08-28mem: adding architectural page table support for SE modeAlexandru
This patch enables the use of page tables that are stored in system memory and respect x86 specification, in SE mode. It defines an architectural page table for x86 as a MultiLevelPageTable class and puts a placeholder class for other ISAs page tables, giving the possibility for future implementation.
2014-01-24arm: 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.

2013-02-19scons: Add warning for overloaded virtual functionsAndreas Hansson
A derived function with a different signature than a base class function will result in the base class function of the same name being hidden. The parameter list and return type for the member function in the derived class must match those of the member function in the base class, otherwise the function in the derived class will hide the function in the base class and no polymorphic behaviour will occur. This patch addresses these warnings by ensuring a unique function name to avoid (unintentionally) hiding any functions.

2010-06-02ARM: Fix SPEC2000 benchmarks in SE mode. With this patch allAli Saidi
Spec2k benchmarks seem to run with atomic or timing mode simple CPUs. Fixed up some constants, handling of 64 bit arguments, and marked a few more syscalls ignoreFunc.

2009-10-30Syscalls: Make system calls access arguments like a stack, not an array.Gabe Black
When accessing arguments for a syscall, the position of an argument depends on the policies of the ISA, how much space preceding arguments took up, and the "alignment" of the index for this particular argument into the number of possible storate locations. This change adjusts getSyscallArg to take its index parameter by reference instead of value and to adjust it to point to the possible location of the next argument on the stack, basically just after the current one. This way, the rules for the new argument can be applied locally without knowing about other arguments since those have already been taken into account implicitly. All system calls have also been changed to reflect the new interface. In a number of cases this made the implementation clearer since it encourages arguments to be collected in one place in order and then used as necessary later, as opposed to scattering them throughout the function or using them in place in long expressions. It also discourages using getSyscallArg over and over to retrieve the same value when a temporary would do the job.
