2013-02-19scons: Add warning for overloaded virtual functionsAndreas Hansson
Fix the ISA startup warnings
2013-01-12x86: Changes to decoder, corrects 9376Nilay Vaish
The changes made by the changeset 9376 were not quite correct. The patch made changes to the code which resulted in decoder not getting initialized correctly when the state was restored from a checkpoint. This patch adds a startup function to each ISA object. For x86, this function sets the required state in the decoder. For other ISAs, the function is empty right now.
2013-01-07arch: Move the ISA object to a separate sectionAndreas Sandberg
After making the ISA an independent SimObject, it is serialized automatically by the Python world. Previously, this just resulted in an empty ISA section. This patch moves the contents of the ISA to that section and removes the explicit ISA serialization from the thread contexts, which makes it behave like a normal SimObject during serialization. Note: This patch breaks checkpoint backwards compatibility! Use the cpt_upgrader.py utility to upgrade old checkpoints to the new format.
2013-01-07arch: Make the ISA class inherit from SimObjectAndreas Sandberg
The ISA class on stores the contents of ID registers on many architectures. In order to make reset values of such registers configurable, we make the class inherit from SimObject, which allows us to use the normal generated parameter headers. This patch introduces a Python helper method, BaseCPU.createThreads(), which creates a set of ISAs for each of the threads in an SMT system. Although it is currently only needed when creating multi-threaded CPUs, it should always be called before instantiating the system as this is an obvious place to configure ID registers identifying a thread/CPU.

2011-03-26mips: cleanup ISA-specific codeKorey Sewell
*** (1): get rid of expandForMT function MIPS is the only ISA that cares about having a piece of ISA state integrate multiple threads so add constants for MIPS and relieve the other ISAs from having to define this. Also, InOrder was the only core that was actively calling this function * * * (2): get rid of corespecific type The CoreSpecific type was used as a proxy to pass in HW specific params to a MIPS CPU, but since MIPS FS hasnt been touched for awhile, it makes sense to not force every other ISA to use CoreSpecific as well use a special reset function to set it. That probably should go in a PowerOn reset fault anyway.
2010-10-10SPARC: Make SPARC's ISA's clear function initialize everything it should.Gabe Black
Also make it not set some pointers to NULL potentially introducing a memory leak. That should be done in the constructor.
2010-10-10Alpha: Force all the IPRs to an initial, determinstic value when cleared.Gabe Black
2009-10-17ISA: Fix compilation.Gabe Black
2009-07-08Get rid of the unused get(Data|Inst)Asid and (inst|data)Asid functions.Gabe Black
2009-07-08Alpha: Pull the MiscRegFile fully into the ISA object.Gabe Black
2009-07-08Registers: Add an ISA object which replaces the MiscRegFile.Gabe Black
This object encapsulates (or will eventually) the identity and characteristics of the ISA in the CPU.
