eddac53ff6 trace: reimplement the DTRACE function so it doesn't use a vector
At the same time, rename the trace flags to debug flags since they
have broader usage than simply tracing.  This means that
--trace-flags is now --debug-flags and --trace-help is now --debug-help

579c5f0b65 Spelling: Fix the a spelling error by changing mmaped to mmapped.
There may not be a formally correct spelling for the past tense of mmap, but
mmapped is the spelling Google doesn't try to autocorrect. This makes sense
because it mirrors the past tense of map->mapped and not the past tense of
cape->caped.

c69d48f007 Make commenting on close namespace brackets consistent.
Ran all the source files through 'perl -pi' with this script:

s|\s*(};?\s*)?/\*\s*(end\s*)?namespace\s*(\S+)\s*\*/(\s*})?|} // namespace $3|;
s|\s*};?\s*//\s*(end\s*)?namespace\s*(\S+)\s*|} // namespace $2\n|;
s|\s*};?\s*//\s*(\S+)\s*namespace\s*|} // namespace $1\n|;

Also did a little manual editing on some of the arch/*/isa_traits.hh files
and src/SConscript.

6833ca7eed Faults: Pass the StaticInst involved, if any, to a Fault's invoke method.
Also move the "Fault" reference counted pointer type into a separate file,
sim/fault.hh. It would be better to name this less similarly to sim/faults.hh
to reduce confusion, but fault.hh matches the name of the type. We could change
Fault to FaultPtr to match other pointer types, and then changing the name of
the file would make more sense.

80d9be86e6 gcc: Add extra parens to quell warnings.
Even though we're not incorrect about operator precedence, let's add
some parens in some particularly confusing places to placate GCC 4.3
so that we don't have to turn the warning off.  Agreed that this is a
bit of a pain for those users who get the order of operations correct,
but it is likely to prevent bugs in certain cases.

54cc0053f0 params: Deprecate old-style constructors; update most SimObject constructors.
SimObjects not yet updated:
- Process and subclasses
- BaseCPU and subclasses

The SimObject(const std::string &name) constructor was removed.  Subclasses
that still rely on that behavior must call the parent initializer as
  : SimObject(makeParams(name))

e99c56f971 SPARC: Move tlb state into the tlb.
Each "strand" may need to have a private copy of this state, but I couldn't
find anywhere in the spec that said that after looking briefly.
This prevents writes to the thread context in o3 which was causing the
pipeline to be flushed and stopping any forward progress. The other ASI
accessible state will probably need to be accessed differently if/when we get
O3 full system up and running.

abc76f20cb Major changes to how SimObjects are created and initialized. Almost all
creation and initialization now happens in python.  Parameter objects
are generated and initialized by python.  The .ini file is now solely for
debugging purposes and is not used in construction of the objects in any
way.

8561c8366c fix smul and sdiv to sign extend, and handle overflow/underflow corretly
Only allow writing/reading of 32 bits of Y
Only allow writing/reading 32 bits of pc when pstate.am
Put any loaded data on the first half of a micro-op in uReg0 so it can't
overwrite the register we are using for address calculation
only erase a entry from the lookup table if it's valid
Put in a temporary check to make sure that lookup table and tlb array stay in sync
if we are interrupted in the middle of a mico-op, reset the micropc/nexpc
so we start  on the first part of it when we come back

4301e4cd08 use pstate.am to mask off PC/NPC where it needs to +be
check writability of tlb cache entry before using
update tagaccess in places I forgot to
move the tlb privileged test up since it is higher priority

src/arch/sparc/faults.cc:
    save only 32 bits of PC/NPC if Pstate.am is set
src/arch/sparc/isa/decoder.isa:
    return only 32 bits of PC/NPC if Pstate.am is set
    increment cleanwin correctly
src/arch/sparc/tlb.cc:
    check writability of cache entry
    update tagaccess in a few more places
    move the privileged test up since it is higher priority
src/cpu/exetrace.cc:
    mask off upper bits of pc if pstate.am is set before comparing to legion

5f662d451e clean up fault code a little bit
simplify and make complete some asi checks
implement all the twin asis and remove panic checks on their use
soft int is supported, so we don't need to print writes to it

src/arch/sparc/asi.cc:
    make AsiIsLittle() be all the little asis.
    Speed up AsiIsTwin() a bit
src/arch/sparc/faults.cc:
    clean up the do*Fault code.... Make it work like legion, in particular
    pstate.priv is left alone, not set to 0 like the spec says
src/arch/sparc/isa/decoder.isa:
    implement some more twin ASIs
src/arch/sparc/tlb.cc:
    All the twin asis are implemented, no need to say their not supported anymore
src/arch/sparc/ua2005.cc:
    softint is supported now, no more need to

e347b49a4e use writeTagAccess() function to unify writing of Tag access registers
Fix extracting of secondary context to shove into tag access register
properly sign extend va from 59 bits to 63 (SPARC VA hole)
