2009-10-27	POWER: Add support for the Power ISA	Timothy M. Jones
	This adds support for the 32-bit, big endian Power ISA. This supports both integer and floating point instructions based on the Power ISA Book I v2.06.
2009-10-17	ISA: Fix compilation.	Gabe Black

2009-10-15	fixed MC146818 checkpointing bug and added isa serialization calls to ↵	Brad Beckmann

2009-10-01	inorder-debug: print out workload	Korey Sewell

2009-09-29	commit Soumyaroop's bug catch about max_insts_all_threads	Lisa Hsu

2009-09-26	O3: Add flag to control whether faulting instructions are traced.	Steve Reinhardt
	When enabled, faulting instructions appear in the trace twice (once when they fault and again when they're re-executed). This flag is set by the Exec compound flag for backwards compatibility.
2009-09-26	O3: Mark fetch stage as active if it faults.	Steve Reinhardt
	Otherwise if the rest of the pipeline is idle then fault will never propagate to commit to be handled, causing CPU to deadlock.

2009-08-01	Fix setting of INST_FETCH flag for O3 CPU.	Steve Reinhardt
	It's still broken in inorder. Also enhance DPRINTFs in cache and physical memory so we can see more easily whether it's getting set or not.

2009-05-12	cpus: add InOrderCPU to default build	Korey Sewell
	regressions need this so they build the model
2009-05-12	inorder-resources: delete events	Korey Sewell
	make sure unrecognized events in the resource pool are deleted and also delete resource events in destructor
2009-05-12	inorder-tlb-cunit: merge the TLB as implicit to any memory access	Korey Sewell
	TLBUnit no longer used and we also get rid of memAccSize and memAccFlags functions added to ISA and StaticInst since TLB is not a separate resource to acquire. Instead, TLB access is done before any read/write to memory and the result is checked before it's sent out to memory. * * *
2009-05-12	inorder-tlb: squash insts in TLB correctly	Korey Sewell
	TLB had a bug where if it was stalled and waiting , it would not squash all instructions older than squashed instruction correctly * * *
2009-05-12	inorder-faults: ignore unalign translation faults for prefetches	Korey Sewell

2009-05-12	inorder-stc: update interface to handle store conditionals	Korey Sewell

2009-05-12	inorder-float: Fix storage of FP results	Korey Sewell
	inorder was incorrectly storing FP values and confusing the integer/fp storage view of floating point operations. A big issue was knowing trying to infer when were doing single or double precision access because this lets you know the size of value to store (32-64 bits). This isnt exactly straightforward since alpha uses all 64-bit regs while mips/sparc uses a dual-reg view. by getting this value from the actual floating point register file, the model can figure out what it needs to store
2009-05-12	inorder-fetch: update model to use predecoder	Korey Sewell

2009-05-12	inorder-mem: clean up allocation/deletion of requests/packets	Korey Sewell
	* * *
2009-05-12	inorder-mem: skeleton support for prefetch/writehints	Korey Sewell

2009-05-12	inorder-o3: allow both to compile together	Korey Sewell
	allow InOrder and O3CPU to be compiled at the same time: need to make branch prediction filed shared by both models
2009-05-12	inorder-unified-tlb: use unified TLB instead of old TLB model	Korey Sewell

2009-05-12	inorder-miscregs: Fix indexing for misc. reg operands and update ↵	Korey Sewell
	result-types for better tracing of these types of values
2009-05-12	inorder/alpha-isa: create eaComp object visible to StaticInst through ISA	Korey Sewell
	Remove subinstructions eaComp/memAcc since unused in CPU Models. Instead, create eaComp that is visible from StaticInst object. Gives InOrder model capability of generating address without actually initiating access * * *
2009-05-12	inorder-bpred: edits to handle non-delay-slot ISAs	Korey Sewell
	Changes so that InOrder can work for a non-delay-slot ISA like Alpha. Typically, changes have to do with handling misspeculated branches at different points in pipeline
2009-05-12	inorder-alpha-port: initial inorder support of ALPHA	Korey Sewell
	Edit AlphaISA to support the inorder model. Mostly alternate constructor functions and also a few skeleton multithreaded support functions * * * Remove namespace from header file. Causes compiler issues that are hard to find * * * Separate the TLB from the CPU and allow it to live in the TLBUnit resource. Give CPU accessor functions for access and also bind at construction time * * * Expose memory access size and flags through instruction object (temporarily memAccSize and memFlags to get TLB stuff working.)
