f58d85128d Fixes so m5 compiles on gcc 3.4, which has much stricter syntax. Most changes come from templated code,
which is evaluated slightly differently than in previous versions of gcc.

arch/alpha/alpha_linux_process.cc:
    Alphabetize includes.
arch/alpha/vptr.hh:
    Change the constants that are being used for alpha pagebytes to come from the ISA.
base/random.hh:
cpu/static_inst.cc:
sim/param.cc:
    Fix up template syntax.
base/range.hh:
    Include iostream for << operator.
base/res_list.hh:
base/statistics.hh:
cpu/simple_cpu/simple_cpu.hh:
cpu/static_inst.hh:
sim/eventq.hh:
sim/param.hh:
    Fixup for templated code to resolve different scope lookup in gcc 3.4.  This defers the lookup of the
    function/variable until actual instantiation time by making it dependent on the templated class/function.
base/trace.cc:
    Fix call to new.
base/trace.hh:
    Fix up #define to have full path.
cpu/base_cpu.cc:
    Fix up call to new.
dev/etherlink.hh:
dev/ns_gige.hh:
dev/sinic.hh:
    Fixup for friend class/function declaration.  g++ 3.4 no longer allows typedefs to be declared as
    a friend class.
dev/pcidev.hh:
    Fix up re-definition of access level to params.
kern/linux/linux_syscalls.hh:
kern/tru64/tru64_syscalls.hh:
    Fix up header.  Fix up template syntax.
sim/serialize.cc:
    Include errno.h.
sim/startup.cc:
    Change startupq.  queue was getting destructed before all things had called ~StartupCallback(), which lead
    to a segfault.  This puts startupq in global space, and we allocate it ourselves.  Other code may be similar
    to this and may need changing in the future.
sim/syscall_emul.hh:
    Include cpu/exec_context.hh and sim/process.hh, as forward declarations are no longer sufficient.
sim/universe.cc:
    Include errno.h

90d4436351 Slight fixes, add in commit trace flag.
base/traceflags.py:
    Add new commit rate trace flag.
build/SConstruct:
    Add extra option for efence.
cpu/beta_cpu/alpha_full_cpu_impl.hh:
    Use function calls instead of direct indexing (avoids confusion).
cpu/beta_cpu/commit_impl.hh:
    Add commit rate trace output (might not be worthwhile in the future).
cpu/beta_cpu/decode_impl.hh:
    Remove some older hacks.  Fix it so that the isntruction properly sets its next
    PC to the one calculated by the branch.
cpu/beta_cpu/fetch_impl.hh:
    Remove old commented code.
cpu/beta_cpu/iew_impl.hh:
    Add extra check to ensure that the instruction is valid.
cpu/beta_cpu/regfile.hh:
    Include trace file.

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)

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.

1d02345a24 a bit more cleaning of the network header wrappers.
base/inet.hh:
    add functions to the various headers to grab the most common
    encapsulated protocols.  This could easily get out of hand, but
    we're just worrying about tcp, udp, and ip for now.

    add common functions size(), bytes(), and payload() to all wrappers.
    size() gets the header size
    bytes() returns a uint8_t * to the beginning of the header
    payload() returns a uint8_t * to the beginning of the payload.

libdnet when we can instead of our own home grown stuff.

base/inet.cc:

    add generic code for calculating ip/tcp/udp checksums
base/inet.hh:
    -  move crc stuff to crc.hh
    -  #include all of the libdnet stuff.  (this makes base/inet.hh the
    only file you need to include if you want to use this kind of stuff.)
    -  Wrap some of the libdnet structs to get easier access to structure
    members.  These wrappers will automatically deal with masking/shifting/
    byte-swapping.

    Basically just gives pointers to ethernet/ip/tcp/udp headers
    if they exist.
dev/etherpkt.hh:
    EtherPacket -> PacketData
    remove most of the packet header stuff from teh PacketData
    class and just add a few generic functions for grabbing various
    headers that may exist in the packet.  The old functionality is
    contained in the headers.
dev/ns_gige.cc:
    -  IP -> Ip, UDP -> Udp, TCP ->Tcp when used in variable names
    -  get rid of our own byte swapping functions.
    -  whack checksum code and use libdnet version.
    -  Get pointers to the various packet headers and grab info from
    those headers.  (The byte swapping in the headers now.)
    -  Add stats for Udp Checksums
dev/ns_gige.hh:
    use libdnet for checksum code.
    IP -> Ip, TCP -> Tcp in variable names
    add stats for UDP checksums

-  KernelStats used to directly implement the pImpl idiom, but
it makes more sense to just remove the level of indirection and
make the exec context have a pointer to the stats.
-  Factor common code out of LinuxSystem and Tru64System and put
it into the System base class.  While doing that, make all
constructors take a pointer to a parameter struct instead of
naming the parameters individually to make it much easier to add
parameters to these classes.

SConscript:
    Move the function tracking and binning stuff around.
arch/alpha/ev5.cc:
    kernelStats is now a pointer
arch/alpha/pseudo_inst.cc:
    kernelStats is now a pointer
    the parameters to the system have been moved into their own
    struct
base/trace.hh:
    provide a little functor class for wrapping a string that
    can allow you to define name() in any scope very simply
    for use with DPRINTF
cpu/base_cpu.cc:
    New order of arguments for consistency.
cpu/exec_context.cc:
    kernelStats no longer has the level of indirection in it,
    execContext has the indirection now.  so, kernelStats is a pointer.
    We also need a pointer to the kernelBinning stuff from the system
    and we need to figure out if we want to do binning or not.
    Move a whole bunch of code into kern_binning.cc so it's all
    in the same place.
cpu/exec_context.hh:
    We want pointers to the kernel binning/stats stuff and we'll
    have the exec_context and system have the level of indirection
    instead of having the extra layer in the kernel stats class.
cpu/simple_cpu/simple_cpu.cc:
    call through the exec context to do the special binning
    stuff.
kern/kernel_stats.cc:
kern/kernel_stats.hh:
    Re-organize the stats stuff and remove the level of indirection
    (that was there to simplify building) and move the binning stuff
    into its own class/file.
kern/linux/linux_system.cc:
kern/linux/linux_system.hh:
kern/tru64/tru64_system.cc:
kern/tru64/tru64_system.hh:
sim/system.cc:
sim/system.hh:
    move lots of common system code into the base system class so
    that it can be shared between linux, tru64, and whatever else
    we decide to support in the future.

    Make the constructor take a pointer to a parameter struct so that
    it is easier to pass parameters to the parent.
kern/system_events.cc:
    move the majority of the binning code into the Kernel::Binning class
    in the kern_binning file
kern/system_events.hh:
    FnEvents only need to know the bin
    create the Idle start event to find the PCBB of the idle
    process when it starts.
kern/tru64/tru64_events.cc:
    memCtrl -> memctrl
sim/process.cc:
sim/process.hh:
    re-order args for consistency

a4d7bb113a Make a new stat type of Value which is a scalar stat that
proxies for a real C/C++ scalar value or scalar functor.
This replaces the scalar() and functor() terms that were
previously used in formulas.  This helps when dumping
statistics because the formulas are not supposed to change.

cpu/base_cpu.cc:
    Add a number of cycles stat to the cpu object that tracks the
    number of cycles that the cpu has executed.  This starts to pave
    the way for cpu cycles being different from event ticks.

    of all CPUs and a virtual function for determining that number.

    move the database stuff into base/stats/statdb.(cc|hh) and
    get rid of the class.  Put everything as globals in the
    Statistics::Database namespace.

    allocate unique ids for all stats.

    directly implement the check routine and get rid of the
    various dumping routines since they're now in separate files.

    make sure that no two stats have the same name

    clean up some loops
base/statistics.hh:
    major changes to the statistics package again

    lots of code was factored out of statistics.hh into several
    separate files in base/stats/ (this will continue)

    There are now two Stat package types Result and Counter that
    are specified to allow the user to keep the counted type
    separate from the result type.  They are currently both doubles
    but that's an experiment.  There is no more per stat ability to
    set the type.  Statistics::Counter is not the same as Counter!

    Implement a visitor for statistics output so that new output
    types can be implemented independently from the stats package
    itself.

    Add a unique id to each stat so that it can be used to keep
    track of stats more simply.  This number can also be used in
    debugging problems with stats.

    Tweak the bucket size stuff a bit to make it work better.

    fixed VectorDist size bug
cpu/memtest/memtest.cc:
    Fix up for changes in stats package
    Don't use value() since it doesn't work with binning.  If you

    you really want two separate variables, one that's a stat,
    and one that's not.

f3861d0cc7 Overall gist of this is to 'dynamicize' the tracking of functions so you can choose them at the .ini stage rather than at compile time.
to do it:
in .ini file set binned_fns=foo null bar foo

what this says is, track foo when it is called by null (i.e. anything).  bin bar only when it is called by foo.
essentially, if you have a path of functions to track, the 0th, 2nd, 4th fn listed are the fns to track, and the 1st, 3rd, 5th are their respective callers.

of an address and a mask

    -  FunctionalMemory no longer takes care of mapping my address into
    the proper address space.  It must be done locally.
    -  the memory controller no longer uses a mask, but a size, and the
    size is determined by the device, not the .ini file

base/range.hh:
    Add a constructor that takes the beginning and end as arguments
    size returns T not a bool
    quick make_range() function that is a shortcut for making a range
    kinda like make_pair()

de285ff2a0 Totally rework the Range class. Now the range is from [start, end)
to be consistent with the way that the stl works.  It also makes
lots of other stuff easier.  (Maybe those guys were smart?)
Overload the various comparison operators so that you can test
for overlapping of ranges, etc.

    Better debugging:
    - Give each class a name() function so that the trace infrastructure
    knows the correct object name.
    - Make the remote debugger capable of detach.
    - Split out the RGDB trace flag into a bunch of specific flags.
