2019-02-25systemc: Add m5.systemc and m5.tlm python modules.Gabe Black
These will be how systemc and tlm APIs which are not attached to SimObjects will be exposed. This avoids having to artificially attach them to wrapping SimObjects for instance, which is a bit awkward and non-obvious. The python code which attaches the systemc and tlm modules to the m5 modules lives in src/python/m5/__init__.py, but the modules themselves live in src/systemc/python to keep all the systemc code grouped together. It might be a little confusing to have a small part of the glue that adds those modules in a separate place (__init__.py), but that is, as far as I can tell, unavoidable, and it's better in my opinion to keep the systemc code grouped together than to put it alongside the other python code and __init__.py.

2019-02-21systemc: Handle exceptions "correctly" even if sc_main hasn't been run.Gabe Black
If sc_main hasn't run, for instance if there isn't an sc_main and gem5 is orchestrating the simulation directly, then exceptions shouldn't be thrown to the sc_main fiber since it isn't running and may not be able to run since sc_main may not even exist. Instead, we need to check whether it makes sense to throw to sc_main, and if not pass the exception directly to the report handler since there likely won't be anyone to catch it if we just throw it from the scheduler or into general purpose gem5. Since the name throwToScMain is no longer a complete description for what that function does, this change renames it to throwUp, since it will now throw exceptions up the stack, either to sc_main or to the conceptual top level by going directly to the report handler.

Some systemc code bases expect to find a SYSTEMC_HOME environment variable which points to the installed header files provided by systemc, all under ${SYSTEMC_HOME}/include. The systemc headers in gem5 are not supposed to be installed anywhere, but to satisfy those expectations this change creates a dummy systemc_home directory with an include/ in it which has headers which just include the actual headers in src/systemc/ext. More gem5 aware code bases can still access the headers either by letting gem5's scons environment -I the ext directory, or can do so themselves if they're not being built by gem5's scons.

There are a couple things this CL fixes related to the TLM #includes. 1. Removes #includes of <systemc> and <tlm>. These bring in a header file from boost which shouldn't be necessary but which some of the tests (and likely some external code) depends on. We avoid including those in files built into gem5 itself so that gem5 isn't dependent on boost. 2. All includes in ext should be relative. That way those headers can be removed from gem5 and still build, allowing them to be moved over to or referenced from a foreign codebase which isn't part of gem5.

2018-12-18systemc: Ensure resets and edges are notified when signaling a change.Gabe Black
Boolean sc_buffers (either pure bool or sc_dt::sc_logic) should signal positive and negative edges and resets even when their value doesn't change, unlike sc_signals. The spec doesn't actually say that and just mentions the value changed event, but it may have been implied that the other types of events also happen, they just made special mention of the value change event. This change moves some code around a bit so that when _signalChange() is called, if the underlying type is a boolean signal, it will automatically notify the appropriate edge event and signal any reset. Putting the functionality in _signalChange instead of delegating it to the sc_buffer lets us have a single template for sc_buffer and makes the base class template specialization handle whether the edge events exist, and if so which should be notified.

2018-12-10systemc: Update test output for longer lived processes.Gabe Black
In the systemc spec, process handles can be invalidated if they have no children and are terminated. The implementation is not required to do so however, and for the sake of simplicity gem5 currently does not. To quote: "When the underlying process instance terminates, if the process instance has no surviving children, an implementation may choose to invalidate any associated process handles, but it is not obliged to do so." Two tests have reference output which is affected by this (legal) difference in behavior. In one case, the test creates new processes which reuse the names of processes that have been terminated. Since gem5 doesn't invalidate the old processes, a standard mechanism is activated which renames the processes to something which is unique. The other test has this same problem, and also prints the hierarchy of processes several times during the test. In that hierarchy, the terminated tests with no live children are still present, where in the old reference output they've been removed. This change updates the reference output to match gem5's behavior.

2018-12-10systemc: Update the ordering in the reference output for some tests.Gabe Black
There are a number of cases where systemc leaves the decision of what order things happen up to the kernel, and any ordering is legal and conformant with the spec as long as it's repeatable. The reference outputs reflect a particular choice of ordering which is implementation specific, and while considerable effort has been made to make the gem5 ordering match the Accellera ordering, at a certain point that's no longer practical or desirable. This change manually updates the reference output for the tests that haven't been excluded for other reasons which have this sort of ordering problem. They have been individually examined, and as best as I can tell changing the output this way does not mask any underlying error. One or two real problems were discovered in addition to the ordering issues, and those were fixed in earlier changes.

2018-12-10systemc: Ignore process control functions on terminated processes.Gabe Black
These functions can descend to the children of a terminated process, but should have no effect on that process itself.

2018-12-10systemc: Update signals before initing processes.Gabe Black
We were supposed to do one update phase before adding all processes which didn't have dont_initialize() called to the run queue. We were doing that in the opposite order.

2018-11-30systemc: Disable systemc when using gcc versions older than 5.0.Gabe Black
These versions don't support the std::put_time function. Since versions of gcc older than 5.0 aren't going to be supported at all in the fairly near future, this should only be temporary. The number of people using both systemc and older versions of gcc should be very small, or even zero.

2018-11-29systemc: Run the systemc tests directly from their build directories.Gabe Black
We were previously running them from the current directory to start with, and then having the config script switch to the build directory. That worked, except when output streams might be opened as part of the global constructors which would run before the config script. This change makes us start from the build directory directly, making the switch in the config script unnecessary and ensuring that no files leak outside of the build when running tests.

2018-11-29systemc: Run the systemc tests with the CWD in the build directory.Gabe Black
This will prevent some (but not all) output files the tests generate from ending up outside the build directory. Because some output file streams are constructed as global objects, their paths are resolved relative to the CWD when gem5 starts, before the config script has a chance to change it. Subsequent changes will make verify.py should make gem5 start with the correct working directory, cleaning up the remaining leaking files.
