2013-10-15	cpu/inorder: merge register class enums	Steve Reinhardt
	The previous patch introduced a RegClass enum to clean up register classification. The inorder model already had an equivalent enum (RegType) that was used internally. This patch replaces RegType with RegClass to get rid of the now-redundant code.
2011-06-19	inorder: clear reg. dep entry after removing from list	Korey Sewell
	this will safeguard future code from trying to remove from the list twice. That code wouldnt break but would waste time.
2011-06-19	inorder: redefine DynInst FP result type	Korey Sewell
	Sharing the FP value w/the integer values was giving inconsistent results esp. when their is a 32-bit integer register matched w/a 64-bit float value
2011-06-19	inorder: remove stalls on trap squash	Korey Sewell

2011-06-19	inorder: no dep. tracking for zero reg	Korey Sewell
	this causes forwarding a bad value register value
2011-06-19	imported patch squash_from_next_stage	Korey Sewell

2011-06-19	inorder: add flatDestReg member to dyninst	Korey Sewell
	use it in reg. dep. tracking
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	trace: reimplement the DTRACE function so it doesn't use a vector	Nathan Binkert
	At the same time, rename the trace flags to debug flags since they have broader usage than simply tracing. This means that --trace-flags is now --debug-flags and --trace-help is now --debug-help
2011-04-15	includes: sort all includes	Nathan Binkert

2011-02-18	inorder: cleanup in destructors	Korey Sewell
	cleanup hanging pointers and other cruft in the destructors
2011-01-07	Replace curTick global variable with accessor functions.	Steve Reinhardt
	This step makes it easy to replace the accessor functions (which still access a global variable) with ones that access per-thread curTick values.
2010-06-24	inorder: enforce 78-character rule	Korey Sewell

2010-04-10	inorder: timing for inst forwarding	Korey Sewell
	when insts execute, they mark the time they finish to be used for subsequent isnts they may need forwarding of data. However, the regdepmap was using the wrong value to index into the destination operands of the instruction to be forwarded. Thus, in some cases, we are checking to see if the 3rd destination register for an instruction is executed at a certain time, when there is only 1 dest. register valid. Thus, we get a bad, uninitialized time value that will stall forwarding causing performance loss but still the correct execution.
2010-01-31	inorder: inst count mgmt	Korey Sewell

2009-09-23	arch: nuke arch/isa_specific.hh and move stuff to generated config/the_isa.hh	Nathan Binkert

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!
