921b1ee87b Add the ability to track stats in user defined sets of function calls. code can be generated via the base/instrum_codegen.pl script to easily change the functions being tracked. the only thing the user needs to do is add code in tru64System to change how the callerMap is populated.
command line:

m5.* <config file> <args> --server.system:bin=true to track function calls in the server
m5.* <config file> <args> --client.system:bin=true to track function calls in the client

base/statistics.cc:
    make an adjustment to the way stats are printed for FS_MEASURE
base/statistics.hh:
    add a name() virtual function to GenBin.  add a debug printf for activate().
    add amake MainBin the default bin when FS_MEASURE.
cpu/exec_context.cc:
    initialize swCtx to null upon creation of an xc
cpu/exec_context.hh:
    add a SWContext pointer to every execution context.
cpu/simple_cpu/simple_cpu.cc:
    process calls and returns for FS_MEASURE
cpu/simple_cpu/simple_cpu.hh:
    add this so idleCycles will not be accessed before all stats are constructed
kern/tru64/tru64_events.cc:
    add a FnEvent that fires whenever a function we're tracking is called.  implement the process() virtual function for it.
kern/tru64/tru64_events.hh:
    add FnEvent
kern/tru64/tru64_system.cc:
    send bin parameter to System constructor.  add bin parameter to Tru64System object.  initialize all the FnEvent and MainBin members of Tru64system.  also, populate the calling map that indicates whether a function call is on the path we're tracking.
kern/tru64/tru64_system.hh:
    modify the Tru64System class to support FS_MEASURE
sim/system.cc:
    add a bin parameter to System class.  initialize a MainBin to hold the stats for nonPath.
sim/system.hh:
    add a map of to match bins to function names.  add a swCtx map to map pcb addresses to SWContext *s.  Add some supporting functions.

02795babaf Fix bugs in and expand syscall emulation code.
arch/alpha/fake_syscall.cc:
    Fix a couple of bugs:
    - error return codes weren't making it through due to inadvertent cast to unsigned
    - sigreturn broken in not one but two ways
    - make all file descriptors look like plain files (not ttys)
    Added implementations of setuid, getgid, fcntl, and getdirentries from Dave Oehmke

667cbb6690 Implement more m5 pseduo opcodes:
resetstats
dumpstats
dumpresetstats
m5checkpoint

Lots of cleanup of serialization and stats dumping/resetting to
work with these new instructions

arch/alpha/isa_desc:
    Implement more m5 pseduo opcodes:
    resetstats
    dumpstats
    dumpresetstats
    m5checkpoint

    All of these functions take two optional parameters, the first is a delay,
    and the second is a period.  The delay tells the simulator to wait the
    specified number of nanoseconds before triggering the event, the period
    tells the simulator to repeat the event with a specified frequency

dev/disk_image.cc:
    serializeFilename -> CheckpointFile()
sim/debug.cc:
    Move this debugging statement to sim_stats.cc
sim/eventq.cc:
    Don't AutoDelete an event if it is scheduled since the process()
    function could potentially schedule the event again.
sim/main.cc:
    DumpStatsEvent is now Statistics::SetupEvent(Dump, curTick)
sim/serialize.cc:
    Change the serialize event so that it's possible to cause the
    event to repeat.  Also make the priority such that the event
    happens just before the simulator would exit if both events
    were scheduled for the same cycle.

    get rid of the serializeFilename variable and provide a CheckpointFile()
    function.  This function takes a basename that is set in the
    configuration, and appends the current cycle to the name so that
    multiple checkpoints can be dumped from the same simulation.

    Also, don't exit the simulation when a checkpoint file is dumped.
sim/serialize.hh:
    serializeFilename -> CheckpointFile()
    SetupCheckpoint function to tell the simulator to prepare
    to checkpoint at a certain time with a certain period
sim/sim_events.cc:
    DumpStatsEvent stuff gets move to sim_stats.(cc|hh)
    The context stuff gets moved into the already existing
    stats context in stat_context.cc
sim/sim_events.hh:
    DumpStatsEvent stuff gets move to sim_stats.(cc|hh)
sim/universe.cc:
    Provide some simple functions for converting times into
    ticks.  These use floating point math to get as close as
    possible to the real values.  Multipliers are set up ahead
    of time

1cd3757db9 add several new functions that can be called from the guest
to tell the simulator to do something.
exit -> exit_old (deprecated
exit now takes an optional parameter that tells it to execute at a
specified time in the future

The next four functions have two optional parameters.  The first
specifies a delay for how long to wait to issue the instruction.
The second will tell the simulator to repeat that command
at the specified interval.

checkpoint will trigger a checkpoint
dumpstats will cause the simulator to dump stats
resetstats will cause all stats to be reset
dumpreset will dump and reset stats


all times are in nanoseconds
