b784903207 O3CPU: Fix thread writeback logic.
Fix the logic in the LSQ that determines if there are any stores to
write back. In the commit stage, check for thread specific writebacks
instead of just any writeback.

712a8ee700 O3CPU: Add a hack to ensure that nextPC is set correctly after syscalls.
Just check CPU's nextPC before and after syscall and if it changes,
update this instruction's nextPC because the syscall must have changed
the nextPC.

38dd9687ce scons: Separate swig environment so we can have different flags.
Swig code isn't quite perfect, so let's not turn on all of the warnings.

6efb930e19 gcc: Version 4.3 is pretty anal about shadowing types, placate it.
In the future, it would be nice to put the O3CPU into its own
namespace so that we don't end up hardcoding pointers to the global
namespace.

ce3d8c2b03 atomicio: provide atomic read and write functions.
These functions keep trying to read and write until all data has been
transferred, or an error occurrs.  In the case where an end of file
hasn't been reached, but all of the bytes have not been read/written,
try again.  On EINTR, try again.

f066db7fcd inifile: Whack preprocessor access.
We haven't used the preprocessor feature of the inifile stuff in a
very long time, so let's get rid of it since it would otherwise take
effort to maintain.

3633a916c2 CPU: Get rid of two more duplicated CPU params. 2008-08-19 21:59:09 -07:00
Richard Strong
8d018aef0f Changed BaseCPU::ProfileEvent's interval member to be of type Tick. This was done to be consistent with its
python type of a latency.  In addition, the multiple definitions of profile in the different cpu models caused
problems for intialization of the interval value. If a child class's profile value was defined, the parent
BaseCPU::ProfileEvent interval field would be initialized with a garbage value. The fix was to remove the
multiple redifitions of profile in the child CPU classes.

ee62a0fec8 params: Convert the CPU objects to use the auto generated param structs.
A whole bunch of stuff has been converted to use the new params stuff, but
the CPU wasn't one of them.  While we're at it, make some things a bit
more stylish. Most of the work was done by Gabe, I just cleaned stuff up
a bit more at the end.

fe8aeff362 Add -r/-e options to redirect stdout/stderr.
Better than using shell since it automatically uses -d directory
for output files (creating it as needed).

50ef39af82 sockets: Add a function to disable all listening sockets.
When invoking several copies of m5 on the same machine at the same
time, there can be a race for TCP ports for the terminal connections
or remote gdb.  Expose a function to disable those ports, and have the
regression scripts disable them.  There are some SimObjects that have
no other function than to be used with ports (NativeTrace and
EtherTap), so they will panic if the ports are disabled.

ede89c2d54 libm5: Create a libm5 static library for embedding m5.
This should allow m5 to be more easily embedded into other simulators.
The m5 binary adds a simple main function which then calls into the m5
libarary to start the simulation. In order to make this work
correctly, it was necessary embed python code directly into the
library instead of the zipfile hack.  This is because you can't just
append the zipfile to the end of a library the way you can a binary.
As a result, Python files that are part of the m5 simulator are now
compile, marshalled, compressed, and then inserted into the library's
data section with a certain symbol name.  Additionally, a new Importer
was needed to allow python to get at the embedded python code.

Small additional changes include:
- Get rid of the PYTHONHOME stuff since I don't think anyone ever used
it, and it just confuses things.  Easy enough to add back if I'm wrong.
- Create a few new functions that are key to initializing and running
the simulator: initSignals, initM5Python, m5Main.

The original code for creating libm5 was inspired by a patch Michael
Adler, though the code here was done by me.

4b1e0d235d scons: Get rid of generate.py in the build system.
I decided that separating some of the scons code into generate.py was
just a bad idea because it caused the dependency system to get all
messed up.  If separation is the right way to go in the future, we
should probably use the sconscript mechanism, not the mechanism that I
just removed.

5f42bfcd56 process: separate stderr from stdout
- Add the option of redirecting stderr to a file. With the old
behaviour, stderr would follow stdout if stdout was to a file, but
stderr went to the host stderr if stdout went to the host stdout.  The
new default maintains stdout and stderr going to the host.  Now the
two can specify different files, but they will share a file descriptor
if the name of the files is the same.
- Add --output and --errout options to se.py to go with --input.
