22c04190c6 misc: Remove redundant compiler-specific defines
This patch moves away from using M5_ATTR_OVERRIDE and the m5::hashmap
(and similar) abstractions, as these are no longer needed with gcc 4.7
and clang 3.1 as minimum compiler versions.

76cd4393c0 sim: Refactor the serialization base class
Objects that are can be serialized are supposed to inherit from the
Serializable class. This class is meant to provide a unified API for
such objects. However, so far it has mainly been used by SimObjects
due to some fundamental design limitations. This changeset redesigns
to the serialization interface to make it more generic and hide the
underlying checkpoint storage. Specifically:

  * Add a set of APIs to serialize into a subsection of the current
    object. Previously, objects that needed this functionality would
    use ad-hoc solutions using nameOut() and section name
    generation. In the new world, an object that implements the
    interface has the methods serializeSection() and
    unserializeSection() that serialize into a named /subsection/ of
    the current object. Calling serialize() serializes an object into
    the current section.

  * Move the name() method from Serializable to SimObject as it is no
    longer needed for serialization. The fully qualified section name
    is generated by the main serialization code on the fly as objects
    serialize sub-objects.

  * Add a scoped ScopedCheckpointSection helper class. Some objects
    need to serialize data structures, that are not deriving from
    Serializable, into subsections. Previously, this was done using
    nameOut() and manual section name generation. To simplify this,
    this changeset introduces a ScopedCheckpointSection() helper
    class. When this class is instantiated, it adds a new /subsection/
    and subsequent serialization calls during the lifetime of this
    helper class happen inside this section (or a subsection in case
    of nested sections).

  * The serialize() call is now const which prevents accidental state
    manipulation during serialization. Objects that rely on modifying
    state can use the serializeOld() call instead. The default
    implementation simply calls serialize(). Note: The old-style calls
    need to be explicitly called using the
    serializeOld()/serializeSectionOld() style APIs. These are used by
    default when serializing SimObjects.

  * Both the input and output checkpoints now use their own named
    types. This hides underlying checkpoint implementation from
    objects that need checkpointing and makes it easier to change the
    underlying checkpoint storage code.

a2d246b6b8 arch: Use shared_ptr for all Faults
This patch takes quite a large step in transitioning from the ad-hoc
RefCountingPtr to the c++11 shared_ptr by adopting its use for all
Faults. There are no changes in behaviour, and the code modifications
are mostly just replacing "new" with "make_shared".

5b557a314f SPARC: Make PSTATE and HPSTATE a BitUnion.
This gets rid of cryptic bits of code with lots of bit manipulation, and makes
some comments redundant.

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

032ea9b2db the way i understand it, interrupts in m5 is a little bloated. the usage of CPU->checkInterrupts bool is inconsistent, and i think should eventually be phased out. For now, I've just assumed that CPU->checkInterrupts() is the way to fast path a CPU if you have no interrupts by having a simple bitfield in each ISA to determine whether interrupts are pending. getInterrupts has been mostly filled in.
src/arch/sparc/interrupts.hh:
    fill in how we do interrupts on sparc a little bit.

    1) create a bitfield for interrupts, and check that in checkInterrupts() to fast path CPU.
    2) fill in getInterrupts() a little bit.

    also, update the bitfield access to be HPSTATE::hpriv, etc.
src/arch/sparc/ua2005.cc:
    1) update formatting
    2) change the way interrupts are done to use the new way to tickle the CPU.
src/cpu/base.cc:
src/cpu/base.hh:
    overload the post_interrupt function for SPARC interrupts - which are only denoted by a single int value.

da6c1f5b09 mostly implemented SOFTINT relevant interrupt stuff.
src/arch/sparc/interrupts.hh:
    add in thread_context.hh to get access to tc.
    get rid of stubs that don't make sense right now.
    implement checking and get softint interrupts
src/arch/sparc/miscregfile.cc:
    softint should be OR-ed on a write.
src/arch/sparc/miscregfile.hh:
    add some enums for state fields for easy access to bitmasks of HPSTATE and PSTATE regs.
src/arch/sparc/ua2005.cc:
    implement writing SOFTINT, PSTATE, PIL, and HPSTATE properly, add helpful info to panic for bad reg write.
