2018-10-16systemc: Switch to using predefined messages for channels.Gabe Black
Create and use predefined messages for channels which match the ones Accellera uses. Change-Id: I179214838bbd83604e50225926cdc6b5b1b16923 Reviewed-on: https://gem5-review.googlesource.com/c/13330 Reviewed-by: Gabe Black <gabeblack@google.com> Maintainer: Gabe Black <gabeblack@google.com>
2018-10-16systemc: Don't depend on the order of static initializers.Gabe Black
STL containers may need to be constructed before they're used. Don't count on being able to insert into them during a static initializer.

2018-10-16systemc: Add a mechanism for pre-registering message type ids.Gabe Black
These ids are the ones the Accellera implementation/tests use. Some of the tests expect them to be available and usable.

2018-10-16systemc: Make suppress_id work like the test expects.Gabe Black
This is in contrast to how Accellera actually implements it, implying they would fail their own test. The specific difference is that suppress_id should only suppress SC_INFO and SC_WARNING, not all severity levels like the Accellera implementation will do.

2018-10-16systemc: Handle integer based IDs like Accellera does.Gabe Black
This is actually not consistent with how it was handled in 2.0.1 which is supposedly what this is supposed to be backwards compatible with, in that in the earlier version on info and warning messages were suppressed. This is exposed by one of the tests, utils/sc_report/test01, which suppresses an integer ID and then reports an error with it. The "golden" output shows the message supressed, but the actual implementation makes no such distinction. This implementation duplicates Accelleras for now, but a future change will make it consistent with the old implementation so the test will pass.

2018-10-16systemc: Refactor reporting to prep for int based messages.Gabe Black
There's a deprecated reporting mechanism based on integer message ids, and the reporting mechanism needs to be refactored a bit to make it easier to support. Some bookkeeping data structures were moved out to somewhere they can be accessed by other code, obviating the non-standard get_handler function.

2018-10-16systemc: Change how the default timescale is set.Gabe Black
The spec says that the default timescale should be 1 PS, but the Accellera implementation uses the time resolution.

2018-10-09systemc: Fortify how exceptions are caught and passed around.Gabe Black
This change tightens up exception catching and makes gem5's systemc code react to exceptions more in line with the Accellera implementation. This prevents exceptions from being caught by the pybind11 integration which makes it very difficult to see where an exception came from, and makes the output differ by including a (mostly useless) backtrace.

The original strings pointed to by those parameters may go away before the sc_report has been completely consumed. By copying them, we make sure other consumers downstream can still access them.

2018-08-15systemc: Add some non-standard sc_trace variants.Gabe Black
These overloads of sc_trace take the unsigned version of some primitive types. The compiler thought it was ambiguous how to convert an unsigned integer value into a signed one since there were several different functions which took signed integer parameters of various sizes. These versions of sc_trace aren't in the standard, but they are in the Accellera implementation and do fix building of the regression tests.
