946b481831 Set LIBELF_LINUX to 0 to build on zax. Builds
but did not test... however the only thing this
affects in libelf is the header, so I don't expect
any functional problems.

base/loader/elf_object.cc:
    Set LIBELF_LINUX to 0 to build on zax.

c9f2aa8c18 Make each stat take up one full line. This allows us to use grep
to find and remove stats from the files so we can put less
burden on the python interpreter.

base/statistics.cc:
    Manually insert newlines into the python code so that we now have one
    stat per line.  (Make it so we can use grep -v to remove stats)
test/stattest.cc:
    update to reflect changes in how python is accessed

9f2aae4e28 Fixes and cleanup to elf loader code.
base/loader/elf_object.cc:
    - Use program header instead of section headers for loading.
    The old code doesn't work for Alpha/Linux user binaries.

    - Deal properly with single-segment ELF executables (e.g. kernels)...
    haven't tested this but it looks like it matches the functionality
    of the patch the L4::Pistachio guys sent.

    - Factor load symbol code into one common function.

    - Some formatting to match style conventions.

    - Only include libelf stuff in .cc file, not .hh.

7e07aa9300 Fix cprintf bug, plus minor cleanup & better error messages.
base/cprintf.cc:
    Fix bug where a call with a format string with no specifiers
    but one or more arguments would crash.  Old code tried to print
    extra args using last available format, but in this case there
    was no format, hence the problem.  Now we just print "<extra arg>"
    for each extra arg.

    Also reorganized code a bit to make scope of fmt variable
    match the scope in which you can be confident it's meaningful.
base/cprintf.hh:
    Print specific error message instead of calling format_invalid().
base/cprintf_formats.hh:
    Clear Format object in constructor.
    Use specific error messages instead of format_invalid() function.

9dcfdce732 Improve python output support
fix some bugs

base/statistics.cc:
    -  Move the python dump stream stuff into the statistics package
    because it needs more control over the file when there
    are multiple dumps
    -  add a subname to the output
    -  make all of the stats a list instead of variable arguments to
    get around the 255 argument limit
    -  the description needs to be triple quoted
    -  avoid errors for formulas that don't have any root element
    set up.
base/statistics.hh:
    -  get rid of mode_python and just separate python dumping from
    regular stats dumping
    -  fix a huge bug that made a Formula use a VectorData instead
    of a FormulaData

55d94ba2e8 Add python output support to the statistics package!
base/statistics.cc:
base/statistics.hh:
    -  add python output support to the statistics package
    -  each statistic type has a python() member function that takes
    a Python object to which the stat will output it's python
    representation
    -  add getStatData hack so that the StatData pointer can be looked
    up by the proxies with their opaque pointer to the stat they're
    proxying for.  This is necessary because the proxy really proxies
    for the bin and not the stat.  Be nice to figure out how to get
    rid of it.  The hack is used so that the str() function of a
    proxy can properly name itself.
    -  To print formula stats, every stat has a str() function that
    converts that stat to a string that python can execute to get
    a value.
test/Makefile:
    add python stuff
test/stattest.cc:
    add more tests and test python support

368de4109f Sweeping change in the stats package....again...
base/statistics.cc:
    -  Merge the m5 display and simplescalar compatible display functions.
    -  Use functors for the stats printing instead of functions.  This
    gets rid of the very long argument lists and improves clarity.
    -  Fix a bug in binning that caused an invalid allocation to occur.
base/statistics.hh:
    -  Instead of using a compile time variable to choose whether
    to print in ss compat mode, we use a runtime variable.
    This is how we'll choose python output.
    -  There are no more virtual functions in the statistics themselves.
    All virtual functions have been moved into a secondary helper class.
    Every stat has an associated helper class that knows how to access
    certain variables in that stat.
    There is a hash_map from the stat to it's helper class data.  This was
    done because the helper data is only used during setup, stats reset,
    and printing.  All of which happen rarely, and you want to avoid
    any performance hit that you can.
    -  To provide the name(), desc(), etc functions to classes so that the
    user can set various parameters to the stats class, a single class
    containing all of those functions was created.  An odd trick was
    done to actually make this class derive from the stat class because
    a base class with no data actually does end up taking up space.
    -  The detail namespace was removed for now.  I'll put it back when the
    package is not in so much flux.
    -  Standard deviation, and mean were added to all distribution stats.
    -  There are several bugfixes and changes that aren't mentioned
test/Makefile:
    Don't test sim_stats foo.
test/stattest.cc:
    Don't test sim_stats foo.
    Fix bin usage so that it corresponds to the current usage.

7976794aad Restructuring of LiveProcess etc. to support multiple emulated OS syscall
interfaces, and specific support for Alpha Linux.  Split syscall emulation
functions into several groups, based on whether they depend on the specific
OS and/or architecture (and all combinations of above), including the use of
template functions to support syscalls with slightly different constants
or interface structs.

arch/alpha/alpha_tru64_process.cc:
    Incorporate full Tru64 object definition here, including structure and constant definitions.
    This way we can wrap all of the functions inside the object, and not worry about namespace

40820042f1 save and restore the current bin during reset since we
should continue in whatever bin we were in.

07d56ae7be better binning of Average stats
base/statistics.hh:
    Try to make binning of Average statistics work a little better.
    This solution is far from perfect though since we really need
    to call set(p.current, p) when the binning takes place.

    To fix the binning, we need to have the current value non-binned,
    to do that, we make make the current value part of the Params struct.
    This means that we can't pass around const Params structs

    Maybe we need a binswap callback :/

655e9ef3de Little fixes to make more of the stats reset correctly.
base/statistics.cc:
    formatting
cpu/simple_cpu/simple_cpu.cc:
cpu/simple_cpu/simple_cpu.hh:
    Make numInsts reset by adding a resetStats function
sim/sim_object.cc:
    Register the reset callback in a slightly cleaner way to avoid
    potential static member constructor ordering issues

f2881c752e Ok, actually call resetStats on all stats
minor gratuitous cleanup in printAllExtraOutput.
(only create one end iterator)

Fix average stats reset

base/statistics.hh:
    Shouldn't reset average stats this way.  The current stat value
    should stay the same.

9471a4d20f Fix stats reset
make SIGUSR2 dump and reset stats
Make resetting time work

base/statistics.cc:
    Fix statistics reset so that it works again, and correctly
    reset bins as well.  (The old code wouldn't reset if you didn't
    have any bins, and then would actually only reset the first
    bin)
cpu/simple_cpu/simple_cpu.cc:
cpu/simple_cpu/simple_cpu.hh:
    convert idleCycles/idleFraction into a single Average stat
    to make reset work more simply
sim/main.cc:
    handle SIGUSR2 to dump and reset stats
    (SIGUSR1 only dumps them)
sim/sim_time.cc:
sim/sim_time.hh:
    Add support for resetting the time
