57ff2604e5 Minor fix plus new assertion to catch similar bugs.
src/cpu/memtest/memtest.cc:
    Need to set packet source field so that response from cache
    doesn't run into assertion failure when copying source to dest.
src/mem/packet.hh:
    Copy source field when copying packets.
    Assert that source is valid before copying it to dest
    when turning packets around.

ea70e6d6da Make branches work by repopulating the predecoder every time through. This is probably fine as far as the predecoder goes, but the simple cpu might want to not refetch something it already has. That reintroduces the self modifying code problem though.

2d08ab0cc2 fix bug in timing cpu. getTime() is the time the requset was created, not the time it was repsonded to. In timing mode the
time it was responded to is curTick. Doesn't change the results, but it does make implementation of nextCycle() more difficult

10fe8b05db Made the "data" field of store queue entries into a character array. It's sized to match an IntReg which was what it used to be, but we might want to make it something architecture independent. All data is now endian converted before entering the store queue entries which simplifies store to load forwarding in "trans endian" simulations, and makes twin memory ops work.

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.

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:

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.

add the ability to tell a memory object to delete it's reference to a port and a method to have a port call deletePortRefs()
on the port owner as well as delete it's peer

02bd40d552 While I'm waiting for legion to run make m5 compile with a few more compilers
SConstruct:
src/SConscript:
    Add flags for Intel CC while i'm at it
src/base/compiler.hh:
    the _Pragma stuff needst to be called this way unless someone happens to have a cleaner way
src/base/cprintf_formats.hh:
    add std:: where appropriate
src/base/statistics.hh:
    use this->map since icc was getting confused about std::map vs the locally defined map
src/cpu/static_inst.hh:
    Add some more dummy returns where needed
src/mem/packet.hh:
    add more dummy returns where needed
src/sim/host.hh:
    use limits to come up with max tick
