i.e. we used to have Foo0, Foo1, ..., Foo10, Foo11, ..., Foo100
now we have Foo000, Foo001, ..., Foo010, Foo011, ..., Foo100

it won't die on binaries compiled with newer glibc's, and enables use of TLS-toolchain built binaries for ALPHA_SE by putting auxiliary vectors on the stack. There are some comments in the code to help. Finally, stats changes for ALPHA are from slight perturbations to the initial stack frame, all minimal diffs.

The gzstream package provides an ostream-interface for writing gzipped files.
The package comes from:
http://www.cs.unc.edu/Research/compgeom/gzstream/
And is distributed under the LGPL license. Both the license and version
information has been preservered, though all other files in the package have
been purged. Minor modifications to the code have been made. The output module
detects when a filename ends in .gz and constructs an ogzstream object instead
of an ofstream object. This works for both the create(...) and find(...)
commands. Additionally, since gzstream objects needs to be closed to ensure
proper file termination, I have the output deconstructor deleting all ostream's
that it manages on behalf of find(...). At the moment, the only output file
that I know this functionality works for is stats, i.e. by specifying
"--stats-file=m5stats.txt.gz" on the command line.

Bogus calls to ChunkGenerator with negative size were triggering
a new assertion that was added there.
Also did a little renaming and cleanup in the process.

I think readData() and writeData() were used for Erik's compression
work, but that code is gone, these aren't called anymore, and they
don't even really do what their names imply.

I did some of the flags and assertions wrong. Thanks to Brad Beckmann
for pointing this out. I should have run the opt regressions instead
of the fast. I also screwed up some of the logical functions in the Flags
class.

The current EXTRAS will fail if the top level directory pointed to by EXTRAS
has a SConscript file in it. We allow this by including the directory name
of the EXTRA in the build directory which prevents a clash between
src/SConscript and extra/SConscript. Maintain compatibility with older uses
of EXTRAS by adding a -I for each top level extra directory.

This instruction basically returns the number of nanoseconds that the CPU
has been running.

Move the constructor into the .cc file and get rid of the typedef for
SendEvent.

We need to add a reference when an object is put on the C++ queue, and remove
a reference when the object is removed from the queue. This was not happening
before and caused a memory problem.

This is to prevent the assertion from firing if you have a large multicore.
Also make sure that it's not compiled in when NDEBUG is defined

In many cases it might be preferable to use bitset, but this object
allows the user more easily manipulate groups of flags because the
underlying type (e.g. uint64_t) is exposed.

In DEBUG mode, this does a dynamic_cast and asserts that the result is
non null. Otherwise, it just does a static_cast. Again, this is only
intended for cases where the cast should always succeed and what's
desired is a debugging check to make sure.

Would have saved me much debugging time if these
had been in there previously.

here is a little change.

connotations for what is really happening and how it should be used.

redundancies with threadId() as their replacement.
|

the primary identifier for a hardware context should be contextId(). The
concept of threads within a CPU remains, in the form of threadId() because
sometimes you need to know which context within a cpu to manipulate.
|

SE. Process still keeps track of the tc's it owns, but registration occurs
with the System, this eases the way for system-wide context Ids based on
registration.

across the subclasses. generally make it so that member data is _cpuId and
accessor functions are cpuId(). The ID val comes from the python (default -1 if
none provided), and if it is -1, the index of cpuList will be given. this has
passed util/regress quick and se.py -n4 and fs.py -n4 as well as standard
switch.

of TimingSimpleCPU.
The constructor no-longer schedules an event at construction and the implict conversion between int and bool was allowing the old code to compile without warning.

Removing hwrei causes
the instruction after the hwrei to be fetched before the ITB/DTB_CM register is updated in a call pal
call sys and thus the translation fails because the user is attempting to access a super page address.
Minimally, it seems as though some sort of fetch stall or refetch after a hwrei is required. I think
this works currently because the hwrei uses the exec context interface, and the o3 stalls when that occurs.
Additionally, these changes don't update the LOCK register and probably break ll/sc. Both o3 changes were
removed since a great deal of manual patching would be required to only remove the hwrei change.
