b29a2d00b8 systemc: Add a filter file for the tests which are expected to work.
Not all of the tests this filter accepts actually work, but we haven't
yet explicitly decided not to try to make them tests work yet.

Recording this in a file makes test runs more repeateable, and creates
a place to record why certain tests or groups of tests are being
excluded.

d3abc7e724 systemc: Add a filter-file option.
The --filter option is very useful, but can get to be long and complex
and a bit too cumbersome to use from the command line. This change
adds a --filter-file option which is mutually exclusive with --filter
and which reads the filter expression from a file instead of accepting
it on the command line.

be from the current code.

contained in the comments probably have not been used since that time.
(This is an example of why one should never add commented code that
is enabled by removing defines. The code rots and sits in the source
forever.)

a51eb91659 systemc: Remove references to internal constants from the tests.
The tests were referring to constants defined in the Accellera systemc
implementation which identified various log message types. This change
replaces those (sometimes quite long) string constants with their
actual value. This doesn't make that interface any more fragile since
the constant value won't track between the Accellera version and this
one, but it does make its fragility more explicit by using the value
directly.

If in the future we decide to hide the magical nature of those
particular string constants, we could make them into our own constants
in the implementation. Regardless, the tests shouldn't refer to
internal details of the implementation.

c172a64db1 systemc: Include boost/bind.hpp in the systemc header.
The systemc spec says that sc_bind, sc_ref and sc_cref macros should
expand to boost::bind, boost::ref, and boost::cref respectively, but
that it's "use is not mandantory". Unfortunately, the regression tests
use those macros without actually including the boost headers for
themselves, and so they won't compile without dragging in these boost
headers as a dependency.

This should be mostly ok to include here since gem5 itself shouldn't
include systemc, just the sub headers that systemc brings in. systemc
code which includes systemc *will* have a dependency on boost, but that
at least contains the new dependency somewhat.

The iterator class needs to have some operators, etc., defined so that
tests written against it can compile correctly. The implementations
were heavily influenced by the Accellera implementation.

Also it should be noted that the systemc spec is incorrect where it
defines these classes. When implemented like they are in the
Accellera version, the versions of bind in sc_vector_assembly which
take sc_vector<T>::iterator and iterator parameters are different, and
so they can overload each other. If implemented as described by the
spec however, those types are the same and the code won't compile.

no reason to include an internal path which is only there on Accellera
by coincidence of the implementation.

42474e6391 systemc: Add a script which automates building and running tests.
The only required option for the script is the path to a build
directory, for instance build/ARM. It uses that when running scons and
when referring to generated files (like the built versions of the
tests). It uses the location of the script itself to find source files,
like the "golden" version of outputs.

This script runs tests in three phases, compilation, running, and
then verification. By default, all three phases are run for all tests,
but which phases run and how they work can be customized by specifying
them explicitly on the command line with the --phase option.

Each time the --phase option shows up on the command line, it should
be followed by the name of the phase being specified. That both
declares that that phase should be run, and also that any subsequent
options apply to that phase, at least until the next --phase option.

Currently, only the "compile" and "execute" phases are implemented, and
only the "compile" phase has been tested at all or has any options
defined. The "compile" phase simply takes all the options it was given
and pass them on to scons. The "verify" phase simply prints a message
which says what it would have verified.

The script can list the available tests with the --list option, as
determined by the json systemc test manifest file which scons can
generate, and which the script can refresh if passed the --update-json
option. You can also specify what "flavor" of build you want to do, ie
opt, debug, fast, etc., with the --flavor option. Only one flavor can
be tested at a time, but that should be the desired behavior most of
the time. If multiple flavors need to be tested, the script can be
invoked multiple times.

Finally, there is a --filter option which accepts a python expression
as a string. That expression is evaluated in the namespace of the
properties of each test in the json file, and if it returns true then
that test is run. For instance, to verify only compile_only tests, you
would use:

systemc/tests/verify.py build/ARM --filter 'compile_only'

To test only compile_only tests named bob, you would run this:

systemc/tests/verify.py build/ARM --filter \
    'compile_only && name ="bob"'

Also included is a simple config.py which is the beginning of a config
which will run the systemc regression tests. Right now, all it knows
how to do is run sc_main.

80bf4c8dbc systemc, scons: Link systemc tests against the shared gem5 library.
Otherwise, having hundreds of statically linked gem5s takes up a huge
amount of space, and all those repeated linkings brings the mightiest
workstation to its knees with sufficient parallelism, or will take
forever without it.

9a457d97b5 systemc: Add a non-standard default writer policy on sc_buffer.
The standard says there's not supposed to be a default writer policy
for the sc_buffer template class, but in the Accellera implementation
there is, and the regression tests depend on it to compile.

This mechanism scans the systemc test directories as described in their
original distribution. It tells scons how to build each test
executable, and also how to build a json manifest file which
lists all the tests and some properties about them.

32ffafe2f4 systemc: Make sc_main run in its own fiber.
The fiber will run until either sc_main returns, or until sc_start is
called. If sc_start is called, then the fiber will only be paused and
waiting for simulation cycles to be run by gem5. Once sc_pause and
sc_stop are implemented, if those are called the sc_main fiber will
be re-entered and allowed to run further towards completion.
