41f6cbce9a Restructure SimpleTimingPort a bit:
- factor out checkFunctional() code so it can be
called from derived classes
- use EventWrapper for sendEvent, move event handling
code from event to port where it belongs
- make sendEvent a pointer so derived classes can
override it
- replace std::pair with new class for readability

a575fbd4aa Completely re-work how the scons framework incorporates swig
and python code into m5 to allow swig an python code to
easily added by any SConscript instead of just the one in
src/python.  This provides SwigSource and PySource for
adding new files to m5 (similar to Source for C++).  Also
provides SimObject for including files that contain SimObject
information and build the m5.objects __init__.py file.

ff7b89beee The process of going from an instruction definition to an instruction to be returned by the decoder has been fleshed out more. The following steps describe how an instruction implementation becomes a StaticInst.
1. Microops are created. These are StaticInsts use templates to provide a basic form of polymorphism without having to make the microassembler smarter.
2. An instruction class is created which has a "templated" microcode program as it's docstring. The template parameters are refernced with ^ following by a number.
3. An instruction in the decoder references an instruction template using it's mnemonic. The parameters to it's format end up replacing the placeholders. These parameters describe a source for an operand which could be memory, a register, or an immediate. It it's a register, the register index is used. If it's memory, eventually a load/store will be pre/postpended to the instruction template and it's destination register will be used in place of the ^. If it's an immediate, the immediate is used. Some operand types, specifically those that come from the ModRM byte, need to be decoded further into memory vs. register versions. This is accomplished by making the decode_block text for these instructions another case statement based off ModRM.
4. Once all of the template parameters have been handled, the instruction goes throw the microcode assembler which resolves labels and creates a list of python op objects. If an operand is a register, it uses a % prefix, an immediate uses $, and a label uses @. If the operand is just letters, numbers, and underscores, it can appear immediately after the prefix. If it's not, it can be encolsed in non nested {}s.
5. If there is a single "op" object (which corresponds to a single microop) the decoder is set up to return it directly. If not, a macroop wrapper is created around it.

In the future, I'm considering seperating the operand type specialization from the template substitution step. A problem this introduces is that either the template arguments need to be kept around for the specialization step, or they need to be re-extracted. Re-extraction might be the way to go so that the operand formats can be coded directly into the micro assembler template without having to pass them in as parameters. I don't know if that's actually useful, though.

e67a207ad3 Add a microcode assembler. A microcode "program" is a series of statements. Each statement has an optional label at the beginning, a capitilized microcode class name which is roughly equivalent to a mnemonic in a regular ISA, and then an optional series of operands seperated by white space. The operands are either a decimal constant, a label, or a code fragment surrounded by non nested {}s. Labels are a letter or underscore followed by letters, underscores, or digits. The syntax for describing code segments might need to be changed if a need arrises to have {}s in the code itself.

941d3168d0 Updates for commit.
1. Move interrupt handling to a separate function to clean up main commit() function a bit.  Also gate the function call off properly based on whether or not there are outstanding interrupts, and the system is not in PAL mode.
2. Better handling of updating instruction's status bits.  Instructions are not marked "atCommit" until other stages view it (pushed off to IEW/IQ), and they have been properly handled (faults).
3. Don't consider the ROB "empty" for the purpose of other stages until the ROB is empty, all stores have written back, and there was no store commits this cycle.  The last is necessary in case a store committed, in which case it would look like all stores have written back but in actuality have not.

src/cpu/o3/commit.hh:
    Slightly modify how interrupts are handled.  Also include some extra bools to keep track of state properly.
src/cpu/o3/commit_impl.hh:
    Slightly modify how interrupts are handled.  Also include some extra bools to keep track of state.

    General correctness updates, most specifically for when commit broadcasts to other stages that the ROB is empty.

78de00091b 3 memory system fixes:
1. Update packet's flags properly when a snoop happens
2. Don't allow accesses to read a block's data if the block has outstanding MSHRs.  This avoids a RAW hazard in MP systems that the memory system was not detecting properly earlier (a write required a block to upgrade, and while the upgrade was outstanding, a read came along and read old data).
3. Update MSHR's request upon a response being handled.  If the MSHR has more targets than it can respond to in one cycle, then its request must be properly updated to the new head of the targets list.

src/mem/bus.cc:
    Update packet's flags properly upon snoop.
src/mem/cache/cache_impl.hh:
    Be sure to not allow accesses to a block with outstanding MSHRs.
src/mem/cache/miss/miss_queue.cc:
    Update MSHR's request upon a response being handled.

e21878c3f2 Handle status bits a little better, as well as non-speculative instructions.
src/cpu/o3/iew_impl.hh:
    Allow for slightly more flexible handling of non-speculative instructions.  They can be other classes now, such as loads or stores.

    Also be sure to clear the state associated with squashes that are not used.  i.e. if a squash due to a memory ordering violation happens on the same cycle as an older branch squashing, clear the state associated with the memory ordering violation.

    Lastly don't consider uncached loads to officially be "at commit" until IEW receives the signal back from commit about the load.
src/cpu/o3/inst_queue_impl.hh:
    Don't consider non-speculative instructions to be "at commit" until the IQ has received a signal from commit about the instruction.  This prevents non-speculative instructions from being issued too early.
src/cpu/o3/mem_dep_unit_impl.hh:
    Clear instruction's ability to issue if it's replayed.

31e78b0b92 Two fixes:
1. Requests are handled more properly now.  They assume the memory system takes control of the request upon sending out an access.
2. load-load ordering is maintained.

src/cpu/base_dyn_inst.hh:
    Update how requests are handled.  The BaseDynInst should not be able to hold a pointer to the request because the request becomes owned by the memory system once it is sent out.

    Also include some functions to allow certain status bits to be cleared.
src/cpu/base_dyn_inst_impl.hh:
    Update how requests are handled.  The BaseDynInst should not be able to hold a pointer to the request because the request becomes owned by the memory system once it is sent out.
src/cpu/o3/fetch_impl.hh:
    General correctness fixes.  retryPkt is not necessarily always set, so handle it properly.  Also consider the cache unblocked only when recvRetry is called.
src/cpu/o3/lsq_unit.hh:
    Handle requests a little more correctly.  Now that the requests aren't pointed to by the DynInst, be sure to delete the request if it's not being used by the memory system.

    Also be sure to not store-load forward from an uncacheable store.
src/cpu/o3/lsq_unit_impl.hh:
    Check to make sure load-load ordering was maintained.

    Also handle requests a little more correctly.

1aef5c06a3 Rework the way SCons recurses into subdirectories, making it
automatic.  The point is that now a subdirectory can be added
to the build process just by creating a SConscript file in it.
The process has two passes.  On the first pass, all subdirs
of the root of the tree are searched for SConsopts files.
These files contain any command line options that ought to be
added for a particular subdirectory.  On the second pass,
all subdirs of the src directory are searched for SConscript
files.  These files describe how to build any given subdirectory.
I have added a Source() function.  Any file (relative to the
directory in which the SConscript resides) passed to that
function is added to the build.  Clean up everything to take
advantage of Source().
function is added to the list of files to be built.

ad44834907 Two fixes:
1. Make sure connectMemPorts() only gets called when the CPU's peer gets changed.  This is done by making setPeer() virtual, and overriding it in the CPU's ports.  When it gets called on a CPU's port (dcache specifically), it calls the normal setPeer() function, and also connectMemPorts().
2. Consolidate redundant code that handles switching in a CPU.

src/cpu/base.cc:
    Move common code of switching over peers to base CPU.
src/cpu/base.hh:
    Move common code of switching over peers to BaseCPU.
src/cpu/o3/cpu.cc:
    Add in function that updates thread context's ports.
    Also use updated function to takeOverFrom() in BaseCPU.  This gets rid of some repeated code.
src/cpu/o3/cpu.hh:
    Include function to update thread context's memory ports.
src/cpu/o3/lsq.hh:
    Add function to dcache port that will update the memory ports upon getting a new peer.
    Also include a function that will tell the CPU to update those memory ports.
src/cpu/o3/lsq_impl.hh:
    Add function that will update the memory ports upon getting a new peer.
src/cpu/simple/atomic.cc:
src/cpu/simple/timing.cc:
    Add function that will update thread context's memory ports upon getting a new peer.
    Also use the new BaseCPU's take over from function.
src/cpu/simple/atomic.hh:
    Add in function (and dcache port) that will allow the dcache to update memory ports when it gets assigned a new peer.
src/cpu/simple/timing.hh:
    Add function that will update thread context's memory ports upon getting a new peer.
src/mem/port.hh:
    Make setPeer virtual so that other classes can override it.

05c86ec0d7 Get X86 to load an elf and start a process for it.
src/arch/x86/SConscript:
    Add in process source files.
src/arch/x86/isa_traits.hh:
    Replace magic constant numbers with the x86 register names.
src/arch/x86/miscregfile.cc:
    Make clear the miscreg file succeed. There aren't any misc regs, so clearing them is very easy.
src/arch/x86/process.hh:
    An X86 process class.
src/base/loader/elf_object.cc:
    Add in code to recognize x86 as an architecture.
src/base/traceflags.py:
    Add an x86 traceflag
src/sim/process.cc:
    Add in code to create an x86 process.
src/arch/x86/intregs.hh:
    A file which declares names for the integer register indices.
src/arch/x86/linux/linux.cc:
src/arch/x86/linux/linux.hh:
    A very simple translation of SPARC's linux.cc and linux.hh. It's probably not correct for x86, but it might not be correct for SPARC either.
src/arch/x86/linux/process.cc:
src/arch/x86/linux/process.hh:
    An x86 linux process. The syscall table is split out into it's own file.
src/arch/x86/linux/syscalls.cc:
    The x86 Linux syscall table and the uname function.
src/arch/x86/process.cc:
    The x86 process base class.
tests/test-progs/hello/bin/x86/linux/hello:
    An x86 hello world test binary.
