2010-06-02	ARM: Set CPSR.E to SCTLR.EE on faults.	Gabe Black

2010-06-02	ARM: Warn about not implementing MPU translation, not panic about MMU.	Gabe Black
	We'll start out with a stbu version of PMSA and switch over to VMSA for the full implementation.
2010-06-02	ARM: Ignore/warn on accesses to the DRBAR, DRACR, and DRSR registers.	Gabe Black

2010-06-02	ARM: Allow access to the RGNR register.	Gabe Black

2010-06-02	ARM: Make the MPUIR register report that 1 unified data region is supported.	Gabe Black

2010-06-02	ARM: Ignore/warn on accesses to the BPIALLIS and BPIALL registers.	Gabe Black

2010-06-02	ARM: Respect the E bit of the CPSR when doing loads and stores.	Gabe Black

2010-06-02	ARM: Zero the micropc when vectoring to a fault.	Gabe Black

2010-06-02	ARM: Implement the V7 version of alignment checking.	Gabe Black

2010-06-02	ARM: Decode the RFE instruction.	Gabe Black

2010-06-02	ARM: Implement the RFE instruction.	Gabe Black

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

2010-06-02	ARM: Make sure some undefined thumb32 instructions fault.	Gabe Black

2010-06-02	ARM: Squash the low order bits of the PC when performing a regular branch.	Gabe Black

2010-06-02	ARM: When changing the CPSR and branching, make sure the branch is second.	Gabe Black

2010-06-02	ARM: Ignore/warn when CSSELR or CCSIDR are accessed.	Gabe Black
	These registers provide information about the caches. Since we can't provide that information, these will be harmlessly inert.
2010-06-02	ARM: Ignore/warn access to the bpimva registers.	Gabe Black

2010-06-02	ARM: Ignore/warn on accesses to the dccmvac register.	Gabe Black

2010-06-02	ARM: Decode the enterx and leavex instructions.	Gabe Black

2010-06-02	ARM: Implement the enterx and leavex instructions.	Gabe Black
	These enter and leave thumbEE mode. Currently thumbEE mode behaves exactly the same as Thumb mode, but at least this will make it -look- like we're enter and leaving it. The actual behavioral changes will be implemented in future changes.
2010-06-02	ARM: Fix the implementation of BX to work in thumbEE mode.	Gabe Black

2010-06-02	ARM: When an instruction is intentionally undefined, fault on it.	Gabe Black

2010-06-02	ARM: Decode the thumb version of the ldrd and strd instructions.	Gabe Black

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

2010-06-02	ARM: Decode the thumb32 load byte/memory hint instructions.	Gabe Black

2010-06-02	ARM: Decode the load halfword, memory hints instructions for 32 bit Thumb.	Gabe Black

2010-06-02	ARM: Ignore/warn on accesses to icimvau.	Gabe Black

2010-06-02	ARM: Ignore/warn on iciallu.	Gabe Black

2010-06-02	ARM: Ignore/warn on ICIALLUIS.	Gabe Black

2010-06-02	ARM: Add support for the clidr register.	Gabe Black
	This register will always report 0 caches as implemented. It's not clear how to find out how many there really are when dealing with an arbitrary hierarchy.
2010-06-02	ARM: Decode the unimplemented data barrier CP15 accesses.	Gabe Black
	These are CP15DSB (Data Synchronization Barrier), and CP15DMB (Data Memory Barrier).
2010-06-02	ARM: Implement a stub of CPACR.	Gabe Black
	This register controls access to the coprocessors. This doesn't actually implement it, it allows writes which don't turn anything off. In other words, it allows the simulated program to ask for what it already has.
2010-06-02	ARM: Actually write the value of sctlr in ISA.clear().	Gabe Black

2010-06-02	ARM: Replace the ARM decode of CP15 MCR and MRC instructions.	Gabe Black

2010-06-02	ARM: Decode the unimplemented cp15 instruction barrier.	Gabe Black

2010-06-02	ARM: Ignore accesses to DCCIMVAC.	Gabe Black

2010-06-02	ARM: Allow accesses to the software thread id registers.	Gabe Black

2010-06-02	ARM: Allow accesses to the contextidr register.	Gabe Black

2010-06-02	ARM: Warn about and ignore accesses to DCCISW.	Gabe Black
	This register is supposed to "Clean and invalidate data or unified cache line by set/way." Since there isn't a good way to do that, we'll just ignore these and warn about it.
2010-06-02	ARM: Decode the thumb versions of the mcr and mrc instructions.	Gabe Black

2010-06-02	ARM: Implement the mrc and mcr instructions.	Gabe Black

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

2010-06-02	ARM: Add a version of the Dest and Op1 operands for accessing the MiscRegs.	Gabe Black

2010-06-02	ARM: Implement a function to decode CP15 registers to MiscReg indices.	Gabe Black

2010-06-02	ARM: Decode the bfi and bfc instructions.	Gabe Black

2010-06-02	ARM: Implement the bfc and bfi instructions.	Gabe Black

2010-06-02	ARM: Decode the ubfx and sbfx instructions.	Gabe Black

2010-06-02	ARM: Decode miscellaneous arm mode media instructions.	Gabe Black

2010-06-02	ARM: Implement the ubfx and sbfx instructions.	Gabe Black

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