2011-07-05	ISA parser: Simplify operand type handling.	Gabe Black
	This change simplifies the code surrounding operand type handling and makes it depend only on the ctype that goes with each operand type. Future changes will allow defining operand types by their ctypes directly, convert the ISAs over to that style of definition, and then remove support for the old style. These changes are to make it easier to use non-builtin types like classes or structures as the type for operands.
2011-07-03	Merged with Gabe's recent changes.	Nilay Vaish

2011-07-03	Network_test: Conform it with functional access changes in Ruby	Nilay Vaish
	Addition of functional access support to Ruby necessitated some changes to the way coherence protocols are written. I had forgotten to update the Network_test protocol. This patch makes those updates.
2011-07-02	tracediff: Check for --debug-flags now instead of --trace-flags.	Gabe Black

2011-07-02	ExecContext: Rename the readBytes/writeBytes functions to readMem and writeMem.	Gabe Black
	readBytes and writeBytes had the word "bytes" in their names because they accessed blobs of bytes. This distinguished them from the read and write functions which handled higher level data types. Because those functions don't exist any more, this change renames readBytes and writeBytes to more general names, readMem and writeMem, which reflect the fact that they are how you read and write memory. This also makes their names more consistent with the register reading/writing functions, although those are still read and set for some reason.
2011-07-02	ExecContext: Get rid of the now unused read/write templated functions.	Gabe Black

2011-07-02	ISA: Use readBytes/writeBytes for all instruction level memory operations.	Gabe Black

2011-07-02	Stats: Update stats for the x86 store fault fix.	Gabe Black

2011-07-02	X86: Fix store microops so they don't drop faults in timing mode.	Gabe Black
	If a fault was returned by the CPU when a store initiated it's write, the store instruction would ignore the fault. This change fixes that.
2011-07-01	Ruby: Commit files missing from previous commit	Nilay Vaish
	The previous commit on functional access support in Ruby did not have some of the files required. This patch adds those files to the repository.
2011-06-30	Regression: Updates regression outputs for Ruby memtest	Brad Beckmann
	This patch updates the regression outputs for Ruby memtest. This was required because of the changes carried out by the addition of functional access support to Ruby.
2011-06-30	config: removed unnecessary slashes	Brad Beckmann
	This patch removes unnecessary slashes from a couple of python scripts.
2011-06-30	Ruby: Add support for functional accesses	Brad Beckmann ext:(%2C%20Nilay%20Vaish%20%3Cnilay%40cs.wisc.edu%3E)
	This patch rpovides functional access support in Ruby. Currently only the M5Port of RubyPort supports functional accesses. The support for functional through the PioPort will be added as a separate patch.
2011-06-28	arch: print next upc correctly	Nilay Vaish
	The patch corrects the print statement which prints the current and the next pc. Instead of the next upc, the next pc was being printed.
2011-06-24	Ruby: remove unused functions in CacheMemory: get/setMemoryValue	Joel Hestness

2011-06-22	mips: fix nmsub and nmadd definitions	Deyaun Guo
	the -/+ signs were flipped for nmsub_s, nmsub_d, and nmadd_d
2011-06-21	X86: Eliminate an unused argument for building store microops.	Gabe Black

2011-06-20	inorder: sparc: add hello world regression	Korey Sewell
	- add InOrderCPU compile option to SPARC - add hello regression for SPARC
2011-06-20	merge regression updates	Korey Sewell

2011-06-20	alpha:o3:simple: update simout/err files	Korey Sewell
	A few prior changesets have changed the gem5 output in a way that wont cause errors but may be confusing for someone trying to debug the regressions. Ones that I caught were: - no more "warn: <hash address" - typo in the ALPHA Prefetch unimplemented warning Additionaly, the last updated stats changes rearrange the ordering of the stats output even though they are still correct stats (gem5 is smart enough to detect this). All the regressions pass w/the same stats even though it looks like they are being changed.

2011-06-19	inorder: update SE regressions	Korey Sewell

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: cleanup dprintfs in cache unit	Korey Sewell

2011-06-19	inorder: SE mode TLB faults	Korey Sewell
	handle them like we do in FS mode, by blocking the TLB until the fault is handled by the fault->invoke()

2011-06-19	inorder: clear fetchbuffer on traps	Korey Sewell
	implement clearfetchbufferfunction extend predecoder to use multiple threads and clear those on trap
2011-06-19	inorder: use separate float-reg bits function in dyninst	Korey Sewell
	this will make sure we get the correct view of a FP register
2011-06-19	inorder: use trapPending flag to manage traps	Korey Sewell

2011-06-19	inorder/dtb: make sure DTB translate correct address	Korey Sewell
	The DTB expects the correct PC in the ThreadContext but how if the memory accesses are speculative? Shouldn't we send along the requestor's PC to the translate functions?
2011-06-19	inorder: handle serializing instructions	Korey Sewell
	including IPR accesses and store-conditionals. These class of instructions will not execute correctly in a superscalar machine
2011-06-19	alpha: fix warn_once for prefetches	Korey Sewell

2011-06-19	alpha: naming for dtb faults	Korey Sewell
	Just "dfault" gets confusing while debugging. Why not differentiate whether it's an access violation or page fault
2011-06-19	inorder: dont handle multiple faults on same cycle	Korey Sewell
	if a faulting instruction reaches an execution unit, then ignore it and pass it through the pipeline. Once we recognize the fault in the graduation unit, dont allow a second fault to creep in on the same cycle.
2011-06-19	inorder: register ports for FS mode	Korey Sewell
	handle "snoop" port registration as well as functional port setup for FS mode
2011-06-19	inorder: check for interrupts each tick	Korey Sewell
	use a dummy instruction to facilitate the squash after the interrupts trap
2011-06-19	inorder: explicit fault check	Korey Sewell
	Before graduating an instruction, explicitly check fault by making the fault check it's own separate command that can be put on an instruction schedule.
