2013-10-15arch/x86: add support for explicit CC register fileYasuko Eckert
Convert condition code registers from being specialized ("pseudo") integer registers to using the recently added CC register class. Nilay Vaish also contributed to this patch.
2012-09-11x86: Add a separate register for D flag bitNilay Vaish
The D flag bit is part of the cc flag bit register currently. But since it is not being used any where in the implementation, it creates an unnecessary dependency. Hence, it is being moved to a separate register.

2012-06-04ISA: Turn the ExtMachInst NoopMachinst into the StaticInstPtr NoopStaticInst.Gabe Black
This eliminates a use of the ExtMachInst type outside of the ISAs.
2012-05-22X86: Split Condition Code registerNilay Vaish
This patch moves the ECF and EZF bits to individual registers (ecfBit and ezfBit) and the CF and OF bits to cfofFlag registers. This is being done so as to lower the read after write dependencies on the the condition code register. Ultimately we will have the following registers [ZAPS], [OF], [CF], [ECF], [EZF] and [DF]. Note that this is only one part of the solution for lowering the dependencies. The other part will check whether or not the condition code register needs to be actually read. This would be done through a separate patch.

2009-08-07X86: Implement shift right/left double microops.Gabe Black
This is my best guess as far as what these should do. Other existing microops use implicit registers, mul1s and mul1u for instance, so this should be ok. The microop that loads the implicit DoubleBits register would fall into one of the microop slots for moving to/from special registers.
