2019-02-26scons: Marshal Python sources using the same Python as gem5Andreas Sandberg
We currently use the Python version used by scons to marshal Python code. This doesn't work when building gem5 with Python 3 support since scons typically runs in Python 2.7. Add a custom marshal helper that links with the same library as gem5 to generate byte code that is guaranteed to work in gem5's Python interpreter.

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.

2019-02-21scons: Add a convenience method to set RPATH for local libraries.Gabe Black
When linking in a dynamic library which is in the gem5 build directory, it's useful to set RPATH so that you don't have to set LD_LIBRARY_PATH when you run gem5 so that the dynamic linker can find it. Since it's tricky and not entirely obvious how to set up those paths correctly, this change adds a small convenience function which does that for you. It also handles situations where the same dynamic library may be linked into different binaries in different directories which each need a different relative RPATH. It does that by letting the environment for each binary set a construction variable which says how to get from that particular binary back to the build directory. This helper method then sets RPATH to start at $ORIGIN (the binary), to follow that relative path to the variant build directory, and then the per-library but not per-binary path to the library's directory. This change also adds the -z origin linker flag which makes the linker handle $ORIGIN properly.

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.

2019-02-20python: Fix Param initialization issue in Python 3Andreas Sandberg
When initializing a param with a SimObject NULL pointer, convert() checks if the 'ptype' attribute has been created and whether the value is NULL. In that case, it assumes that the object is being initizalized as a part of SimObject initialization and defers the conversion. This check is implemented using hasattr() which in turn is implemented using the __getattr__ implementation that asserts because all SimObjects haven't been initialized yet. Implement the check using a lookup in the object's dictionary instead to prevent the SimObject lookup.

2019-02-19sim: Add a mechanism to exit the simulation loop immediately.Gabe Black
There are some cases, specifically when running systemc, that it's necessary to exit the simulation loop immediately rather than finishing running events scheduled for the current Tick. When running under sc_main, sc_stop and sc_pause return control to sc_main which can happen immediately. When running without sc_main, control needs to return to the python config script which needs to happen through a global exit event. Since sc_pause and sc_stop are supposed to stop simulation without necessarily letting all the events at the current time run, we need a way to schedule an exit event with a very high priority (rather than a very low priority). This change adds a new exitSimLoopNow function which does that, and adds a new constructor to the GlobalSimLoopExitEvent which uses that priority. Also, a couple of cruft functions from the sim events are removed.
