58c29640b7 Add a new operation class for IPR accesses, and have IPR-accessing
instructions use it (instead of IntALU, as before).  Default config
has a single non-pipelined 3-cycle unit.  A bit conservative for the
ev6 (some are 1, some are 3).

arch/alpha/isa_desc:
    Make hw_mfpr and hw_mtpr use IprAccessOp op class.
cpu/full_cpu/op_class.hh:
    Add IprAccess.

368882a847 Fix timing modeling of faults: functionally the very next instruction after
a faulting instruction is the fault handler, which appears as an independent
instruction to the timing model.  New code will stall fetch and not fetch the
fault handler as long as there's a faulting instruction in the pipeline (i.e.,
the faulting inst has to commit first).

Also fix Ali's bad-address assertion that doesn't apply to full system.

Added some more debugging support in the process.  Hopefully we'll move to the new
cpu model soon and we won't need it anymore.

arch/alpha/alpha_memory.cc:
    Reorganize lookup() so we can trace the result of the lookup as well.
arch/alpha/isa_traits.hh:
    Add NoopMachInst (so we can insert them in the pipeline on ifetch faults).
base/traceflags.py:
    Replace "Dispatch" flag with "Pipeline" (since I added similar
    DPRINTFs in other pipe stages).
cpu/exetrace.cc:
    Change default for printing mis-speculated instructions to true (since
    that's often what we want, and right now you can't change it from the
    command line...).

    - Remove all direct support for .ini files.  They are strictly
    for intermediate representation.
    - Remove the --foo:bar=blah syntax for .ini files and add --foo.bar=blah
    syntax for python.  This will generate: foo.bar = 'blah' in the python
    script.
    - Add '-d' to set the output directory.
    - Use new output file code to access the output stream.

0aaf8ec6b8 Add support for CPU models to execute the effective
address calculation and memory access portions separately.
Not currently used by any CPU models, but Kevin says he needs this.

Also clean up handling of execution tracing for memory accesses
(move it all into isa_desc and out of CPU models).

Got rid of some ancient unused code too.

arch/alpha/isa_desc:
    Add execute() methods to EAComp and MemAcc portions of memory
    access instructions, to allow CPU models to execute the effective
    address calculation and memory access portions separately.

    Requires the execution context to remember the effective address
    across the two invocations.  Added setEA() and getEA() methods to
    execution context to support this.  A model that does not use the
    split execution model can panic if these methods are called.

    Also added hook to call traceData->setAddr() after EA computation
    on any load or store operation.
arch/isa_parser.py:
    Call traceData->setData() on memory writes (stores).
cpu/simple_cpu/simple_cpu.cc:
    Get rid of unused code.
cpu/simple_cpu/simple_cpu.hh:
    Add (non-functional) setEA() and getEA() methods for new
    split memory access execution support.

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.

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:

cpu/pc_event.hh:

9023f5c96d - Clean up and factor out all of the binning code into a
single place so it's easier to work with.
-  Add support for binning kernel/user/idle time separately from
lisa's binning stuff, but make the two compatible.
-  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

838273a196 fix up the recordEvent stuff to support ignoring events
arch/alpha/ev5.cc:
cpu/simple_cpu/simple_cpu.cc:
    update for new event interface
base/stats/events.cc:
    implement the ignore event function which matches sim objects from which
    to ignore events.

    Make insert event like insert data and make it able to insert many
    events in a single transaction with the database.
base/stats/events.hh:
    Make it possible to ignore events
sim/sim_object.cc:
    make recordEvent a member function of SimObject to implement
    the ignore function easily
sim/sim_object.hh:
    implement the ignore event stuff in the sim object.  This is a
    bit of a hack, but an easy place to put it.
