2018-10-16systemc: Switch to using predefined messages for datatypes.Gabe Black
Create and use predefined messages for datatypes which match the ones Accellera uses. Change-Id: I92dd52f62462b864264217bb81f3ff1dcec020bf Reviewed-on: https://gem5-review.googlesource.com/c/13331 Reviewed-by: Gabe Black <gabeblack@google.com> Maintainer: Gabe Black <gabeblack@google.com>

2018-10-16systemc: Add a simple implementation for sc_mempool.Gabe Black
This class is supposed to be a more efficient way to manage small bits of memory. At least for now, new and delete will do the same job functionally. Also, the heap manager may be just as efficient as whatever custom mechanism sc_mempool would use.

2018-10-09systemc: Ensure SC_LONG_64 is defined and available.Gabe Black
The datatype code was checking if SC_LONG_64 was defined to determine if a long was 64 bits. The code that would define that value was dropped when porting over from the Accellera implementation, and so the wrong code was being included. This change both makes those checks look at the *value* of SC_LONG_64 to ensure that it's not missing by accident, and assigns it a value in sc_fxdefs.hh.

2018-10-03systemc: "Fix" some error message formatting.Gabe Black
These changes make the output match what Accellera outputs so that the tests will pass. Change-Id: I1260cec35fa39586fbef39047b9da4ff3c03b3ed Reviewed-on: https://gem5-review.googlesource.com/c/12592 Reviewed-by: Gabe Black <gabeblack@google.com> Maintainer: Gabe Black <gabeblack@google.com>
2018-10-03systemc: Adjust some error messages to match Accellera.Gabe Black
Those messages include an error number in the Accellera implementation. Add those numbers to gem5 so it's easier to check against golden reference output for the regression tests.

2018-09-25systemc: Implement most of sc_inout.Gabe Black
Because sc_inout needs sc_dt::sc_logic and that probably calls functions from dt_sc_mempool.cc and because those hadn't yet been stubbed out. This change adds stubs for those as well.

2018-07-24systemc: Seperate the "external" header interface.Gabe Black
Most (but not all) of the SystemC headers are part of the "external" interface that an existing, standard compliant module would include through <systemc.h> or <systemc>. Since those follow slightly different rules (relative includes, no gem5 includes), this change separates them out so that they're easier to identify. Also, this change moves the other files into a "core" subdirectory, with the intention to add a "dt", aka data type, directory some time in the future when those standard defined types are implemented.
