19e5efed03 Pseudo instructions are now passed whatever instructions they need by the decoder, rather than extracting them explicitly. This lets most of the pseudo instruction code to be shared across architectures.
SConscript:
    Moved pseudo_inst.hh from targetarch to full system sources
arch/alpha/SConscript:
    Moved pseudo_inst.cc out of the alpha specific sources
arch/alpha/isa/decoder.isa:
    The decoder now pulls out the arguments for the pseudo instructions based on the alpha ABI
arch/alpha/isa/main.isa:
    Registers 16, 17 and 18 are used to get parameters for the pseudo instructions and can be referred to explicitly
sim/pseudo_inst.cc:
    Changed some include paths to reflect that pseudo_inst.hh is now outside of the alpha directory. Also, instead of extracting their parameters directly, they're passed in as regular function arguments.
sim/pseudo_inst.hh:
    Changed the function prototypes to include the functions parameters, now that they aren't extracted from the execution context.

2c5e03550a Removed isa_traits.hh from targetarch, moved vptr.hh from arch/alpha to sim, fixed an include to have the new location, and removed an ambiguating function declaration in byteswap.hh.
SConscript:
    Moved isa_fullsys_traits.hh out of targetarch, since the only place it's included, and the only place the comments in the file say it should be included, is in the alpha isa_traits.hh
    targetarch/isa_traits.hh is now included through arch/isa_traits.hh

sim/vptr.hh:
    Fixed the assert in the equals operator.
    Changed the AlphaISA namespace reference to TheISA.
    Changed arch/alpha/vtophys.hh to targetarch/vtophys.hh, since this file is now for all architectures.
    Added an include of arch/isa_traits.hh so that TheISA would be defined.

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.

8f2e096275 Minor cleanup of operand type and traits code in isa_parser.py.
arch/isa_parser.py:
    Minor cleanup of operand type and traits code:
    - build operand size map right away when types are defined
    instead of waiting to do it lazily
    - check that operand types have been defined before operands
    - don't use 'type' as a variable name
    - use isinstance() instead of checking for types directly

3cc6c59582 Add keyword parameters and list-valued arguments to
instruction format functions in ISA description language.

Take advantage of these features to clean up memory
instruction definitions in Alpha.

arch/alpha/isa/decoder.isa:
arch/alpha/isa/mem.isa:
arch/alpha/isa/pal.isa:
    Take advantage of new keyword parameters to disambiguate
    instruction vs. memory-request flags, and to provide
    a default EA calculation for memory ops (since 99% of them
    are the same).
arch/isa_parser.py:
    Add two new features to instruction format functions:
    - Keyword parameters, a la Python.
    - List-valued arguments.

    Also export makeList() function to Python code blocks,
    as this is handy for dealing with flags.

3923eec0ef Change how memory operands are handled in ISA descriptions.
Should enable implementation of split-phase timing loads
with new memory model.
May create slight timing differences under FullCPU, as I
believe we were not handling software prefetches correctly
before when the split MemAcc/Exec model was used.  I haven't
looked into this in any detail though.

arch/alpha/isa/decoder.isa:
    HwLoadStore format split into separate HwLoad and
    HwStore formats.
    Copy instructions now fall under MiscPrefetch format.
    Mem_write_result is now just write_result in store
    conditionals.
arch/alpha/isa/mem.isa:
    Split MemAccExecute and LoadStoreExecute templates
    into separate templates for loads and stores; now
    that memory operands are handled differently from
    registers, it's impossible to have a single template
    serve both.
    Also unified the handling of "regular" prefetches
    (loads to r31) and "misc" prefetches (e.g., wh64)
    under the new scheme.  It looks like SW prefetches
    were not handled correctly in FullCPU up til now,
    since we generated an execute() method for the outer
    instruction but didn't generate a proper method for
    MemAcc::execute() (instead getting a default no-op
    method for that).
arch/alpha/isa/pal.isa:
    Split HwLoadStore into separate HwLoad and HwStore
    formats to select proper template (see change to
    mem.isa in this changeset).
arch/isa_parser.py:
    Stop trying to treat memory operands like register
    operands, since we never used them in a uniform way
    anyway, and it made it impossible to do split-phase
    loads as needed for the new CPU model.  Now there's no
    more 'op_mem_rd', 'op_nonmem_rd', etc.: 'op_rd' just does
    register operands, and the template code is responsible
    for formulating the call to the memory system.  Right now
    the only thing exported by InstObjParams is a new attribute
    'mem_acc_size' which gives the memory access size in bits,
    though more attributes can be added if needed.

    Also moved code in findOperands() method to
    OperandDescriptorList.__init__(), which is where it belongs.

5cfc5e8080 The first fully coded version of decoder.isa!!!!!
=================================================
-every MIPS32 ISA is represented with some type
of code block.
-any instruction that doesnt have a code block
would be of format WarnUnimpl. Examples of the
ones I am waiting on further info to implement
are the TLB register insts, memory consistency
instructions (ll,sc,etc.) and software debug
insts.

879aaa5569 Change how isa_parser.py generates C++ names for isa_desc operands.
arch/isa_parser.py:
    Get rid of "munged name" for operands in C++ code.
    That is, "Ra.uq" will now be known in the C++ as "Ra"
    rather than "Ra_uq".  It wasn't legal to use different
    type extensions for the same operand at the same time
    anyway, and now it will be easier to refer to explicit
    operands in template code if necessary.

7219693f4c Actually we do need a separate class for Integer Ops with Immediates!!!
The extra class is needed because of the necessisty of an immediate member variable.

Also, added some 'very modest' python code to choose between the IntOp and
the IntImmOp based on the instruction name ...

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

eabb0cfc78 Pushing current state. Need to fix compilation problems, have moved the SCONS script to build memory objects first.
Some places I could have been using a forward decleration and that should be cleaned up as well.

SConscript:
    Changed to move new memory object compilation to the top.  See the errors right away.
    Will also need to update all other objects that included the old memory system to use the new one.  But not until we at least get the mem system compiling first.
mem/packet.hh:
    Adding includes and typedefs to fix compilation errors
mem/request.hh:
    Add definition for compilation issues

Output,Format, & Template code needs to be adjusted to correctly take these "decoder.h" inputs ...

989292a0fa Update for new memory system. Uses the ports to access memory now. Also supports the response path of the new memory system, as well as retrying accesses.
cpu/simple/cpu.cc:
    Update for new memory system.  Supports using ports to access the memory system.  The IcacheMissStall/DcacheMissStall statuses have been changed to reflect the cache returning a response after a variable latency (due to hit/miss).  They are now DcacheWaitResponse/IcacheWaitResponse.  Also supports retrying accesses.

    For now the body of the copy functions are commented out.
cpu/simple/cpu.hh:
    Update for new memory system.
