19534176e0 load/store instruction format ... now generates load/store code
and breaks it into a separate EA and MemAccess templated
from how the Alpha ARch. was coded to do the same thing.

arch/mips/isa/bitfields.isa:
    comment change
arch/mips/isa/decoder.isa:
    re-structuring of load/store instruction definitions
arch/mips/isa/formats/mem.isa:
    Define LoadMemory & Store Memory formats
    Use style of formatting & base class similar to what was used for ALPHA
arch/mips/isa/formats/util.isa:
    Insert LoadStoreBase function here from alpha/arch/isa/mem.isa
arch/mips/isa/operands.isa:
    change shw->sh and uhw->uh

a48c24b61e Support NNPC and branch instructions ... Outputs to decoder.cc correctly
Edits to the CPU model may still need to be made to handle branch likely insts...

arch/isa_parser.py:
    add a NNPC operand ...
arch/mips/isa/base.isa:
    change SPARC to MIPS
arch/mips/isa/decoder.isa:
    typo < to >=
arch/mips/isa/formats/basic.isa:
    spacing
arch/mips/isa/formats/branch.isa:
    add code for branch instructions (still need adjustments for the branch likely)
arch/mips/isa/operands.isa:
    support for NNPC and R31
arch/mips/isa_traits.hh:
    NNPC Addr variable

159e334531 use string name to figure out if we have a "AndLink" instruction
arch/mips/isa/operands.isa:
    uq -> uw

23bbec6a34 another big step to a parsable ISA ... no errors after I used a symbolic link for
arch/alpha/main.isa to test my files ...

arch/mips/isa/operands.isa:
    use sd and ud instead of sdw and udw

79613686f0 Polishing of isa_parser.py internal operand handling, resulting in
minor change to syntax of 'def operands' in ISA descriptions.

arch/alpha/isa/main.isa:
arch/mips/isa/operands.isa:
arch/sparc/isa/operands.isa:
    Change 'def operands' statement to work with new
    isa_parser changes.
arch/isa_parser.py:
    Merge OperandTraits and OperandDescriptor objects into a
    unified hierarchy of Operand objects.
    Required a change in the syntax of the 'def operands'
    statement in the ISA description.

d30262d480 name changes ... minor IntOP format change
arch/mips/isa/formats/int.format:
    Looks like Integer Ops with Immediates may not need their own separate class because all those instructions are distinct from
    their reg-reg counterparts
