2018-10-16systemc: Implement general and VCD trace support.Gabe Black
This doesn't include WIF trace support, but does make allowances for adding it in the future. Change-Id: Ifb62f40a7d8a13e94463930a44ac4b1cf41e3009 Reviewed-on: https://gem5-review.googlesource.com/c/12826 Reviewed-by: Gabe Black <gabeblack@google.com> Maintainer: Gabe Black <gabeblack@google.com>
2018-10-16systemc: Change an error message to match the reference outputs.Gabe Black
This is different from the message the Accellera implementation would print, so it looks like it wouldn't pass this test as is.

This required a small change to sc_signal so that the value change event and the change stamp for it were accessible.

2018-10-03systemc: Implement sc_fifo::dump and improve sc_fifo::print.Gabe Black
The print function is supposed to print both pending and committed writes, apparently. Accellera's implementation of sc_fifo uses a ring buffer to store the entries and manages a head and tail pointer to keep track of what's full, etc. Their dump function prints that whole buffer using the indexes. When not using a ring buffer, there's no easy way to determine what those indexes should be. Fortunately the test that uses dump never moves away from the base of the ring buffer, so I can get the same effect (which also makes sense on its own) by printing the index into the fifo instead.

There are still some bugs since the output of the tests don't all match, but more tests pass and fewer abort.

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.

2018-08-08Systemc: Port over all of the systemc "datatype" headers.Gabe Black
These are the headers originally written by Accellera with a few modifications. Most significantly, I went through and mostly (but not entirely) manually editted them to conform to gem5 style and to be more self consistent. Second, I resolved some macros which optionally select features. I removed support for deprecated functions, and otherwise enabled everything. The actual implementation behind these headers will also be ported over, but in a subsequent change.
