Mostly a matter of keeping prefetches to invalid addrs
from messing up VM IPRs. Also discovered that wh64s were
not being treated as prefetches, when they really should be
(for the most part, anyway).
arch/alpha/alpha_memory.cc:
arch/alpha/alpha_memory.hh:
- Get rid of intrlock flag for locking VM fault regs (a la EV5);
instead, just don't update regs on VPTE loads (a la EV6).
- Add NO_FAULT MemReq flag to indicate references that should not
cause page faults (i.e., prefetches).
arch/alpha/ev5.cc:
- Get rid of intrlock flag for locking VM fault regs (a la EV5);
instead, just don't update regs on VPTE loads (a la EV6).
- Add Fault trace flag.
arch/alpha/isa_desc:
- Add NO_FAULT MemReq flag to indicate references that should not
cause page faults (i.e., prefetches).
- Mark wh64 as a "data prefetch" instruction so it gets controlled
properly by the FullCPU data prefetch control switch.
- Align wh64 EA in decoder so issue stage doesn't need to worry about it.
arch/alpha/isa_traits.hh:
- Get rid of intrlock flag for locking VM fault regs (a la EV5);
instead, just don't update regs on VPTE loads (a la EV6).
base/traceflags.py:
- Add Fault trace flag.
cpu/simple_cpu/simple_cpu.hh:
- Pass MemReq flags to writeHint() operation.

useful when we're generating dozens of files when we flesh out the
object description stuff.
remove generated files from the source tree. python is required

Add support for generic visitors for stats and use them
to implement independent output functions.

base/statistics.cc:
move the python output code to base/stats/puthon.(cc|hh)
and reimplement it as a visitor.
move the text output code to base/stats/text.(cc|hh) and
reimplement it as a visitor.
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
want a number as a stat, and to use it in the program itself,
you really want two separate variables, one that's a stat,
and one that's not.
