2011-01-18	ARM: Add support for moving predicated false dest operands from sources.	Ali Saidi

2010-11-08	ARM: Make all ARM uops delayed commit.	Ali Saidi

2010-10-22	ISA: Simplify various implementations of completeAcc.	Gabe Black

2010-10-22	ARM: Don't pretend to writeback registers in initiateAcc.	Gabe Black

2010-10-13	Mem: Change the CLREX flag to CLEAR_LL.	Gabe Black
	CLREX is the name of an ARM instruction, not a name for this generic flag.
2010-08-25	ARM: Use fewer micro-ops for register update loads if possible.	Gene WU
	Allow some loads that update the base register to use just two micro-ops. three micro-ops are only used if the destination register matches the offset register or the PC is the destination regsiter. If the PC is updated it needs to be the last micro-op otherwise O3 will mispredict.
2010-08-25	ARM: Fix VFP enabled checks for mem instructions	Ali Saidi

2010-08-25	ARM: Fix type comparison warnings in Neon.	Gabe Black

2010-08-25	ARM: Implement CPACR register and return Undefined Instruction when FP ↵	Gabe Black
	access is disabled.
2010-08-25	ARM: Implement all ARM SIMD instructions.	Gabe Black

2010-08-23	MEM: Make CLREX a first class request operation and clear locks in caches ↵	Gene Wu
	when it in received
2010-08-23	ARM: Don't write tracedata on writes, it might have been freed already.	Gene Wu

2010-08-23	ARM: Implement CLREX init/complete acc methods	Gene Wu

2010-08-23	ARM/O3: store the result of the predicate evaluation in DynInst or Threadstate.	Min Kyu Jeong
	THis allows the CPU to handle predicated-false instructions accordingly. This particular patch makes loads that are predicated-false to be sent straight to the commit stage directly, not waiting for return of the data that was never requested since it was predicated-false.
2010-06-02	ARM: Fix IT state not updating when an instruction memory instruction faults.	Min Kyu Jeong

2010-06-02	ARM: Decode to specialized conditional/unconditional versions of instructions.	Gabe Black
	This is to avoid condition code based dependences from effectively serializing instructions when the instruction doesn't actually use them.
2010-06-02	ARM: Implement support for the IT instruction and the ITSTATE bits of CPSR.	Gabe Black

2010-06-02	ARM: Clean up the implementation of the VFP instructions.	Gabe Black

2010-06-02	ARM: Introduce new VFP base classes that are optionally microops.	Gabe Black

2010-06-02	ARM: Add a new RegImmOp base class.	Gabe Black

2010-06-02	ARM: Add a RegRegImmOp base class.	Gabe Black

2010-06-02	ARM: Widen the immediate fields in the misc instruction classes.	Gabe Black

2010-06-02	ARM: Add a base class for SRS.	Gabe Black

2010-06-02	ARM: Make a base class for instructions that use only an immediate.	Gabe Black

2010-06-02	ARM: Implement the strex instructions.	Gabe Black

2010-06-02	ARM: Add a base class for the RFE instruction.	Gabe Black

2010-06-02	ARM: Explicitly keep track of the second destination for double loads/stores.	Gabe Black

2010-06-02	ARM: Rename the RevOp base class to something more generic.	Gabe Black

2010-06-02	ARM: Add a register, immediate, immediate to register base for [su]bfx.	Gabe Black

2010-06-02	ARM: Add a base class to support usada8.	Gabe Black

2010-06-02	ARM: Add a base class for the sel instruction.	Gabe Black

2010-06-02	ARM: Add a base class for extend and add instructions.	Gabe Black

2010-06-02	ARM: Generalize the saturation instruction bases for use in other instructions.	Gabe Black

2010-06-02	ARM: Implement base classes for the saturation instructions.	Gabe Black

2010-06-02	ARM: Add base classes suitable for the REV* instructions.	Gabe Black

2010-06-02	ARM: Implement the swp and swpb instructions.	Gabe Black

2010-06-02	ARM: Define versions of MSR and MRS outside the decoder.	Gabe Black

2010-06-02	ARM: Add templates for VFP load/store multiple instructions.	Gabe Black

2010-06-02	ARM: Move the macro mem constructor out of the isa desc.	Gabe Black
	This code doesn't use the parser at all, and moving it out reduces the conceptual complexity of that code.
2010-06-02	ARM: Make macroops panic if executed directly.	Gabe Black
	The macroop should never be executed, only it's microops will.
2010-06-02	ARM: GCC < 4.3 has some issues with attribute no return on some functions. ↵	Ali Saidi
	Fix so it works for older gccs.
2010-06-02	ARM: Split out the "basic" templates and format.	Gabe Black
	--HG-- rename : src/arch/arm/isa/formats/basic.isa => src/arch/arm/isa/templates/basic.isa
2010-06-02	ARM: Add templates for multiply instructions.	Gabe Black

2010-06-02	ARM: Add new templates for branch instructions.	Gabe Black

2010-06-02	ARM: Implement data processing instructions external to the decoder.	Gabe Black

2010-06-02	ARM: Reimplement load/store multiple external to the decoder.	Gabe Black
	--HG-- rename : src/arch/arm/isa/formats/macromem.isa => src/arch/arm/isa/insts/macromem.isa rename : src/arch/arm/isa/formats/macromem.isa => src/arch/arm/isa/templates/macromem.isa
2010-06-02	ARM: Move the templates for predicated instructions into a separate file.	Gabe Black
	This allows the templates to all be available at the same time before any of the formats, etc. This breaks an artificial circular dependence. --HG-- rename : src/arch/arm/isa/formats/pred.isa => src/arch/arm/isa/templates/pred.isa
2010-06-02	ARM: Define the store instructions from outside the decoder.	Gabe Black
	--HG-- rename : src/arch/arm/isa/insts/ldr.isa => src/arch/arm/isa/insts/str.isa
2010-06-02	ARM: Define the load instructions from outside the decoder.	Gabe Black
