2011-06-19	inorder: make marking of dest. regs an explicit request	Korey Sewell
	formerly, this was implicit when you accessed the execution unit or the use-def unit but it's better that this just be something that a user can specify.
2011-06-19	inorder: register file stats	Korey Sewell
	keep stats for int/float reg file usage instead of aggregating across reg file types
2011-06-19	inorder: add types for dependency checks	Korey Sewell

2011-06-19	inorder: use flattenIdx for reg indexing	Korey Sewell
	- also use "threadId()" instead of readTid() everywhere - this will help support more complex ISA indexing
2011-04-15	includes: sort all includes	Nathan Binkert

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: initialize res. req. vectors based on resource bandwidth	Korey Sewell
	first change in an optimization that will stop InOrder from allocating new memory for every instruction's request to a resource. This gets expensive since every instruction needs to access ~10 requests before graduation. Instead, the plan is to allocate just enough resource request objects to satisfy each resource's bandwidth (e.g. the execution unit would need to allocate 3 resource request objects for a 1-issue pipeline since on any given cycle it could have 2 read requests and 1 write request) and then let the instructions contend and reuse those allocated requests. The end result is a smaller memory footprint for the InOrder model and increased simulation performance
2010-06-24	inorder: cleanup virtual functions	Korey Sewell
	remove the annotation 'virtual' from function declaration that isnt being derived from
2010-06-24	inorder: enforce 78-character rule	Korey Sewell

2010-06-23	inorder-stats: add instruction type stats	Korey Sewell
	also, remove inst-req stats as default.good for debugging but in terms of pure processor stats they aren't useful
2010-01-31	inorder: ctxt switch stats	Korey Sewell
	- m5 line enforcement on use_def.cc,hh
2009-05-26	types: add a type for thread IDs and try to use it everywhere	Nathan Binkert

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
2009-02-10	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!
