2011-02-23	inorder: InstSeqNum bug	Korey Sewell
	Because int and not InstSeqNum was used in a couple of places, you can overflow the int type and thus get wierd bugs when the sequence number is negative (or some wierd value)
2011-02-18	inorder: remove request map, use request vector	Korey Sewell
	take away all instances of reqMap in the code and make all references use the built-in request vectors inside of each resource. The request map was dynamically allocating a request per instruction. The request vector just allocates N number of requests during instantiation and then the surrounding code is fixed up to reuse those N requests *** setRequest() and clearRequest() are the new accessors needed to define a new request in a resource
2011-02-18	inorder: remove reqRemoveList	Korey Sewell
	we are going to be getting away from creating new resource requests for every instruction so no more need to keep track of a reqRemoveList and clean it up every tick
2011-02-12	inorder: utilize cached skeds in pipeline	Korey Sewell
	allow the pipeline and resources to use the cached instruction schedule and resource sked iterator
2010-09-13	Faults: Pass the StaticInst involved, if any, to a Fault's invoke method.	Gabe Black
	Also move the "Fault" reference counted pointer type into a separate file, sim/fault.hh. It would be better to name this less similarly to sim/faults.hh to reduce confusion, but fault.hh matches the name of the type. We could change Fault to FaultPtr to match other pointer types, and then changing the name of the file would make more sense.
2009-09-23	arch: nuke arch/isa_specific.hh and move stuff to generated config/the_isa.hh	Nathan Binkert

2009-05-26	types: add a type for thread IDs and try to use it everywhere	Nathan Binkert

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-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-mem: skeleton support for prefetch/writehints	Korey Sewell

2009-05-12	inorder-unified-tlb: use unified TLB instead of old TLB model	Korey Sewell

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.)
2009-04-08	tlb: Don't separate the TLB classes into an instruction TLB and a data TLB	Gabe Black

2009-03-04	Give each resource in InOrder it's own TraceFlag instead of just standard ↵	Korey Sewell
	'Resource' flag
2009-02-25	ISA: Replace the translate functions in the TLBs with translateAtomic.	Gabe Black

2009-02-25	CPU: Get rid of translate... functions from various interface classes.	Gabe Black

2009-02-10	InOrder: Import new inorder CPU model from MIPS.	Korey Sewell
	This model currently only works in MIPS_SE mode, so it will take some effort to clean it up and make it generally useful. Hopefully people are willing to help make that happen!
