All protocols must specify their name
The include statement allows any file to include another file.

This makes it possible to use the grammar multiple times and use the multiple
instances concurrently. This makes implementing an include statement as part
of a grammar possible.

This change simplifies the code surrounding operand type handling and makes it
depend only on the ctype that goes with each operand type. Future changes will
allow defining operand types by their ctypes directly, convert the ISAs over
to that style of definition, and then remove support for the old style. These
changes are to make it easier to use non-builtin types like classes or
structures as the type for operands.

Addition of functional access support to Ruby necessitated some changes to
the way coherence protocols are written. I had forgotten to update the
Network_test protocol. This patch makes those updates.

readBytes and writeBytes had the word "bytes" in their names because they
accessed blobs of bytes. This distinguished them from the read and write
functions which handled higher level data types. Because those functions don't
exist any more, this change renames readBytes and writeBytes to more general
names, readMem and writeMem, which reflect the fact that they are how you read
and write memory. This also makes their names more consistent with the
register reading/writing functions, although those are still read and set for
some reason.

If a fault was returned by the CPU when a store initiated it's write, the
store instruction would ignore the fault. This change fixes that.

The previous commit on functional access support in Ruby did not have
some of the files required. This patch adds those files to the repository.

|
This patch updates the regression outputs for Ruby memtest. This was
required because of the changes carried out by the addition of functional
access support to Ruby.
|
|
This patch removes unnecessary slashes from a couple of python scripts.
|
|
This patch rpovides functional access support in Ruby. Currently only
the M5Port of RubyPort supports functional accesses. The support for
functional through the PioPort will be added as a separate patch.

The patch corrects the print statement which prints the current and
the next pc. Instead of the next upc, the next pc was being printed.

the -/+ signs were flipped for nmsub_s, nmsub_d, and nmadd_d

- add InOrderCPU compile option to SPARC
- add hello regression for SPARC

A few prior changesets have changed the gem5 output in a way that wont cause
errors but may be confusing for someone trying to debug the regressions. Ones that I caught
were:
- no more "warn: <hash address"
- typo in the ALPHA Prefetch unimplemented warning
Additionaly, the last updated stats changes rearrange the ordering of the stats output even though
they are still correct stats (gem5 is smart enough to detect this). All the regressions pass
w/the same stats even though it looks like they are being changed.

variable name typo.

previous commit copied over O3 stats, this one puts the inorder ones in the right place

this will safeguard future code from trying to remove
from the list twice. That code wouldnt break but would
waste time.

handle them like we do in FS mode, by blocking the TLB until the fault
is handled by the fault->invoke()

implement clearfetchbufferfunction
extend predecoder to use multiple threads and clear those on trap
|
|
this will make sure we get the correct view of a FP register
|

The DTB expects the correct PC in the ThreadContext
but how if the memory accesses are speculative? Shouldn't
we send along the requestor's PC to the translate functions?

including IPR accesses and store-conditionals. These class of instructions will not
execute correctly in a superscalar machine
