2019-01-10base: Make it possible to convert strings to enumsGiacomo Travaglini
The __to_number helper function defined in base/str.hh is used by unserializing code. Its purpose is to convert a string into an integral/floating point number. Since enums underlying type can only be an integer type, it makes sense to extend the helper function for enums as well. In this way it will be possible to unserialize Enums and containers of Enums without the need of casting.

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.

2018-12-06base: Iterable CircularQueue implementationRekai Gonzalez-Alberquilla
The former implementation of CircleBuf is functional but a bit too tailored to match a use-case. This patches introduces a new iterable circular queue, which adds some more functionality so it can also be used for the newer LSQ implementation, where iteration and iterators are a very desirable feature.
