2014-09-03	arch: Cleanup unused ISA traits constants	Andreas Hansson
	This patch prunes unused values, and also unifies how the values are defined (not using an enum for ALPHA), aligning the use of int vs Addr etc. The patch also removes the duplication of PageBytes/PageShift and VMPageSize/LogVMPageSize. For all ISAs the two pairs had identical values and the latter has been removed.
2012-11-02	ISA: generic Linux thread info support	Dam Sunwoo
	This patch takes the Linux thread info support scattered across different ISA implementations (currently in ARM, ALPHA, and MIPS), and unifies them into a single file. Adds a few more helper functions to read out TGID, mm, etc. ISA-specific information (e.g., ALPHA PCBB register) is now moved to the corresponding isa_traits.hh files.
2012-06-05	ISA: Back-out NoopMachInst as a StaticInstPtr change.	Ali Saidi

2012-06-04	ISA: Turn the ExtMachInst NoopMachinst into the StaticInstPtr NoopStaticInst.	Gabe Black
	This eliminates a use of the ExtMachInst type outside of the ISAs.
2011-09-09	StaticInst: Merge StaticInst and StaticInstBase.	Gabe Black
	Having two StaticInst classes, one nominally ISA dependent and the other ISA dependent, has not been historically useful and makes the StaticInst class more complicated that it needs to be. This change merges StaticInstBase into StaticInst.
2011-01-03	Make commenting on close namespace brackets consistent.	Steve Reinhardt
	Ran all the source files through 'perl -pi' with this script: s\|\s(};?\s)?/\\s(end\s)?namespace\s(\S+)\s\/(\s})?\|} // namespace $3\|; s\|\s};?\s//\s(end\s)?namespace\s(\S+)\s\|} // namespace $2\n\|; s\|\s};?\s//\s(\S+)\snamespace\s\|} // namespace $1\n\|; Also did a little manual editing on some of the arch/*/isa_traits.hh files and src/SConscript.

	When each load or store is sent to the LSQ, we check whether it will cross a cache line boundary and, if so, split it in two. This creates two TLB translations and two memory requests. Care has to be taken if the first packet of a split load is sent but the second blocks the cache. Similarly, for a store, if the first packet cannot be sent, we must store the second one somewhere to retry later. This modifies the LSQSenderState class to record both packets in a split load or store. Finally, a new const variable, HasUnalignedMemAcc, is added to each ISA to indicate whether unaligned memory accesses are allowed. This is used throughout the changed code so that compiler can optimise away code dealing with split requests for ISAs that don't need them.
2009-10-27	POWER: Add support for the Power ISA	Timothy M. Jones
	This adds support for the 32-bit, big endian Power ISA. This supports both integer and floating point instructions based on the Power ISA Book I v2.06.
