2010-04-10inorder: timing for inst forwardingKorey Sewell
when insts execute, they mark the time they finish to be used for subsequent isnts they may need forwarding of data. However, the regdepmap was using the wrong value to index into the destination operands of the instruction to be forwarded. Thus, in some cases, we are checking to see if the 3rd destination register for an instruction is executed at a certain time, when there is only 1 dest. register valid. Thus, we get a bad, uninitialized time value that will stall forwarding causing performance loss but still the correct execution.

2010-04-02eventq: Clean up some flagsNathan Binkert
- Make the initialized flag always available, not just in debug mode. - Make the Initialized flag actually use several bits so it is very unlikely that something that's uninitialized accidentally looks initialized. - Add an initialized() function that tells you if the current event is indeed initialized. - Clear the flags on delete so it can't be accidentally thought of as initialized. - Fix getFlags assert statement. "How did this ever work?"
2010-04-02eventq: Make priorities just an integer instead of an enum.Nathan Binkert
Symbolic names should still be used, but this makes it easier to do things like: Event::Priority MyObject_Pri = Event::Default_Pri + 1 Remember that higher numbers are lower priority (should we fix this?)
2010-04-02refcnt: no default copy contructor or copy operatorNathan Binkert
We shouldn't allow these because the default versions will copy the reference count which is definitely not what we want.

2010-04-02ruby: get "using namespace" out of headersNathan Binkert
In addition to obvious changes, this required a slight change to the slicc grammar to allow types with :: in them. Otherwise slicc barfs on std::string which we need for the headers that slicc generates.

2010-03-27inorder: write-hints bug fixKorey Sewell
make sure to only read 1 src reg. for write-hint and any other similar 'store' instruction. Reading the source reg when its not necessary can cause the simulator to read from uninitialized values

2010-03-23cpu: get rid of uncached access "events"Steve Reinhardt
These recordEvent() calls could cause crashes since they access the req pointer after it's potentially been deleted during a failed translation call. (Similar problem to the traceData bug fixed in the previous cset.) Moving them above the translation call (as was done recentlyi in cset 8b2b8e5e7d35) avoids the crash but doesn't work, since at that point we don't know if the access is uncached or not. It's not clear why these calls are there, and no one seems to use them, so we'll just delete them. If they are needed, they should be moved to somewhere that's guaranteed to be after the translation completes but before the request is possibly deleted, e.g., in finishTranslation().
2010-03-23cpu: fix exec tracing memory corruption bugSteve Reinhardt
Accessing traceData (to call setAddress() and/or setData()) after initiating a timing translation was causing crashes, since a failed translation could delete the traceData object before returning. It turns out that there was never a need to access traceData after initiating the translation, as the traced data was always available earlier; this ordering was merely historical. Furthermore, traceData->setAddress() and traceData->setData() were being called both from the CPU model and the ISA definition, often redundantly. This patch standardizes all setAddress and setData calls for memory instructions to be in the CPU models and not in the ISA definition. It also moves those calls above the translation calls to eliminate the crashes.

2010-03-21ruby: Disable adaptive routing by for faster simulation perf.Brad Beckmann
2010-03-21ruby: Changed the default set size to 1Brad Beckmann
Previously, the set size was set to 4. This was mostly do to the fact that a crazy graduate student use to create networks with 256 l2 cache banks. Now it is far more likely that users will create systems with less than 64 of any particular controller type. Therefore Ruby should be optimized for a set size of 1.
