Polina Dudnik 0b0f47ec16 Added proc_id to CacheMsg for SMT. 
Not yet necessary, but in case each of the threads
is allowed to initiate an atomic, will come in handy

Gabe Black 6e97feb8a5 X86: Make not taken conditional moves leave the destination alone. Adjust CMOVcc. 
The manuals from both AMD and Intel say that when writing to a 32 bit
destination in 64 bit mode, the upper 32 bits of the register are filled with
zeros. They also both say that the CMOV instructions leave their destination
alone when their condition fails. Unfortunately, it seems that CMOV will zero
extend its destination register whether or not it was supposed to actually do
a move on both platforms. This seems to be the only case where this happens,
but it would be hard to say for sure.

Gabe Black 3a55fc5cac X86: Implement shift right/left double microops. 
This is my best guess as far as what these should do. Other existing microops
use implicit registers, mul1s and mul1u for instance, so this should be ok.
The microop that loads the implicit DoubleBits register would fall into one
of the microop slots for moving to/from special registers.

we should truncate them explicitly.

Derek Hower 33b28fde7a slicc: added MOESI_CMP_directory, DMA SequencerMsg, parameterized controllers 
This changeset contains a lot of different changes that are too
mingled to separate.  They are:

1.  Added MOESI_CMP_directory

I made the changes necessary to bring back MOESI_CMP_directory,
including adding a DMA controller.  I got rid of MOESI_CMP_directory_m
and made MOESI_CMP_directory use a memory controller. Added a new
configuration for two level protocols in general, and
MOESI_CMP_directory in particular.

2.  DMA Sequencer uses a generic SequencerMsg

I will eventually make the cache Sequencer use this type as well.  It
doesn't contain an offset field, just a physical address and a length.
MI_example has been updated to deal with this.

3. Parameterized Controllers

SLICC controllers can now take custom parameters to use for mapping,
latencies, etc.  Currently, only int parameters are supported.

Steve Reinhardt a13a706a20 Fix setting of INST_FETCH flag for O3 CPU.

Steve Reinhardt 1c28004654 Clean up some inconsistencies with Request flags. 2009-08-01 22:50:13 -07:00
Steve Reinhardt c0755e6085 Rename internal Request fields to start with '_'. 
The inconsistency was causing a subtle bug with some of the
constructors where the params had the same name as the fields.
This is also a first step to switching the accessors over to
our new "standard", e.g., getVaddr() -> vaddr().

If the control flow of M5's executable and statetrace's target process get out

will be useful. There's also almost no hope for recovery. In those cases, we
might as well give up and not generate a huge, mostly worthless trace file.
