4328480b56 Don't use the global check_interrupts variable. Add a per-cpu
checkInterrupts variable and use that to determine whether an interrupt
can occur on a given cycle.

arch/alpha/ev5.cc:
    XC -> CPU (and xc -> CPU) since we're really talking about a CPU here
    Don't use the global check_interrupts variable.  Add a per-cpu
    checkInterrupts variable and use that to determine whether an interrupt
    can occur on a given cycle.

78ae8764a9 add a new phase to the simulator. Basically the simulator now goes
through the following phases.

1) Construct all param contexts
2) Call the checkParams() on each context
3) Build the configuration hierarchy
4) Construct all SimObjects
5) Initialize all SimObjects by calling init() on each one
6) Unserialize the checkpoint
7) Register all statisitcs
8) Check validity of all statistics (after that, no new stats)
9) Reset all stats.
10) Call SimStartup() which calls startup() on all SimObjects,
ParamContexts, and any other object deriving from StartupCallback

SConscript:
    no more SimInit() we have SimStartup() now
sim/param.hh:
    Make all params have a startup callback.
sim/sim_events.cc:
    the init callbacks no longer exist.  We can simplify code by
    using startup().
sim/sim_object.hh:
    Make all SimObjects derive from StartupCallback

f834289a51 Do the targetarch dependency stuff better.
SConscript:
    targetarch is only for headers, not cc files.  move all cc files
    back to arch/alpha, and make the target arch directory do this
    echo '#include "arch/alpha/foo.hh"' > targetarch/foo.hh for every
    header file.  This works a lot better and doesn't kill emacs'
    ability to parse compile outputs

b881408ed7 Clean up the Range class and associated usages. The code was
never clear about whether the end of the range was inclusive
or exclusive.  Make it inclusive, but also provide a RangeSize()
function that will generate a Range based on a start and a size.
This, in combination with using the comparison operators, makes
almost all usages of the range not care how it is stored.

base/range.cc:
    Make the end of the range inclusive.

    start/end -> first/last
    (end seems too much like end() in stl)
base/range.hh:
    Make the end of the range inclusive.

    Fix all comparison operators so that they work correctly with
    an inclusive range.  Also, when comparing one range to another
    with <, <=, >, >=, we only look at the beginning of the range
    beacuse x <= y should be the same as x < y || x == y.  (This wasn't
    the case before.)

    Add a few functions for making a range:
    RangeSize is start and size
    RangeEx is start and end where end is exclusive
    RangeIn is start and end where end is inclusive

    start/end -> first/last
    (end seems too much like end() in stl)

    hold a proper history of the RAS so it can be restored on branch
    mispredicts.
cpu/beta_cpu/bpred_unit_impl.hh:
    Added in stats, history of branches, RAS.  Now bpred unit actually
    modifies the instruction's predicted next PC.

eaf66f4658 fix some bugs in the headers and fix checksumming.
base/inet.cc:
    we can't use a uint16_t for the intermediate checksum values
    since there may be some bits that carry.
    the length that is added in the pseudo header is the length of
    the tcp portion only.
base/inet.hh:
    silly me, the ip_hlen field is in terms of 4-byte words.
    when caclulating checksum, we're dealing with network byte order,
    so don't bother doing any byteswapping.

e3fb9afa79 Update to make multiple instruction issue and different latencies work.
Also change to ref counted DynInst.

SConscript:
    Add branch predictor, BTB, load store queue, and storesets.
arch/isa_parser.py:
    Specify the template parameter for AlphaDynInst
base/traceflags.py:
    Add load store queue, store set, and mem dependence unit to the
    list of trace flags.
cpu/base_dyn_inst.cc:
    Change formating, add in debug statement.
cpu/base_dyn_inst.hh:
    Change DynInst to be RefCounted, add flag to clear whether or not this
    instruction can commit.  This is likely to be removed in the future.
cpu/beta_cpu/alpha_dyn_inst.cc:
    AlphaDynInst has been changed to be templated, so now this CC file
    is just used to force instantiations of AlphaDynInst.
cpu/beta_cpu/alpha_dyn_inst.hh:
    Changed AlphaDynInst to be templated on Impl.  Removed some unnecessary
    functions.
cpu/beta_cpu/alpha_full_cpu.cc:
    AlphaFullCPU has been changed to be templated, so this CC file is now
    just used to force instantation of AlphaFullCPU.
cpu/beta_cpu/alpha_full_cpu.hh:
    Change AlphaFullCPU to be templated on Impl.
cpu/beta_cpu/alpha_impl.hh:
    Update it to reflect AlphaDynInst and AlphaFullCPU being templated
    on Impl.  Also removed time buffers from here, as they are really
    a part of the CPU and are thus in the CPU policy now.
cpu/beta_cpu/alpha_params.hh:
    Make AlphaSimpleParams inherit from the BaseFullCPU so that it doesn't
    need to specifically declare any parameters that are already in the
    BaseFullCPU.
cpu/beta_cpu/comm.hh:
    Changed the structure of the time buffer communication structs.  Now
    they include the size of the packet of instructions it is sending.
    Added some parameters to the backwards communication struct, mainly
    for squashing.
cpu/beta_cpu/commit.hh:
    Update typenames to reflect change in location of time buffer structs.
    Update DynInst to DynInstPtr (it is refcounted now).
cpu/beta_cpu/commit_impl.hh:
    Formatting changes mainly.  Also sends back proper information
    on branch mispredicts so that the bpred unit can update itself.
    Updated behavior for non-speculative instructions (stores, any
    other non-spec instructions): once they reach the head of the ROB,
    the ROB signals back to the IQ that it can go ahead and issue the
    non-speculative instruction.  The instruction itself is updated so that
    commit won't try to commit it again until it is done executing.
cpu/beta_cpu/cpu_policy.hh:
    Added branch prediction unit, mem dependence prediction unit, load
    store queue.  Moved time buffer structs from AlphaSimpleImpl to here.
cpu/beta_cpu/decode.hh:
    Changed typedefs to reflect change in location of time buffer structs
    and also the change from DynInst to ref counted DynInstPtr.
cpu/beta_cpu/decode_impl.hh:
    Continues to buffer instructions even while unblocking now.  Changed
    how it loops through groups of instructions so it can properly block
    during the middle of a group of instructions.
cpu/beta_cpu/fetch.hh:
    Changed typedefs to reflect change in location of time buffer structs
    and the change to ref counted DynInsts.  Also added in branch
    brediction unit.
cpu/beta_cpu/fetch_impl.hh:
    Add in branch prediction.  Changed how fetch checks inputs and its
    current state to make for easier logic.
cpu/beta_cpu/free_list.cc:
    Changed int regs and float regs to logically use one flat namespace.
    Future change will be moving them to a single scoreboard to conserve
    space.
cpu/beta_cpu/free_list.hh:
    Mostly debugging statements.  Might be removed for performance in future.
cpu/beta_cpu/full_cpu.cc:
    Added in some debugging statements.  Updated BaseFullCPU to take
    a params object.
cpu/beta_cpu/full_cpu.hh:
    Added params class within BaseCPU that other param classes will be
    able to inherit from.  Updated typedefs to reflect change in location
    of time buffer structs and ref counted DynInst.
cpu/beta_cpu/iew.hh:
    Updated typedefs to reflect change in location of time buffer structs
    and use of ref counted DynInsts.
cpu/beta_cpu/iew_impl.hh:
    Added in load store queue, updated iew to be able to execute non-
    speculative instructions, instead of having them execute in commit.
cpu/beta_cpu/inst_queue.hh:
    Updated change to ref counted DynInsts.  Changed inst queue to hold
    non-speculative instructions as well, which are issued only when
    commit signals backwards that a nonspeculative instruction is at
    the head of the ROB.
cpu/beta_cpu/inst_queue_impl.hh:
    Updated to allow for non-speculative instructions to be in the inst
    queue.  Also added some debug functions.
cpu/beta_cpu/regfile.hh:
    Added debugging statements, changed formatting.
cpu/beta_cpu/rename.hh:
    Updated typedefs, added some functions to clean up code.
cpu/beta_cpu/rename_impl.hh:
    Moved some code into functions to make it easier to read.
cpu/beta_cpu/rename_map.cc:
    Changed int and float reg behavior to use a single flat namespace.  In
    the future, the rename maps can be combined to a single rename map to
    save space.
cpu/beta_cpu/rename_map.hh:
    Added destructor.
cpu/beta_cpu/rob.hh:
    Updated it with change from DynInst to ref counted DynInst.
cpu/beta_cpu/rob_impl.hh:
    Formatting, updated to use ref counted DynInst.
cpu/static_inst.hh:
    Updated forward declaration for AlphaDynInst now that it is templated.
