The out pointer of a vvp_net_t object is going to be a bit more
sophisticated when we redo the handling of net signals. Take a step
towards this rework by making the pointer private and implementing
methods needed to access it.
This patch fixes a bunch of memory leaks in vvp and converts the
T_STRING lexical token to be new based. There are still two
known leaks that I need to find a way to fix and likely some
unknown leaks that still need to be found and fixed.
Remove the #ident and $Log$ strings from all the header files and
almost all of the C/C++ source files. I think it is better to get
this done all at once, then to wait for each of the files to be
touched and edited in unrelated patches.
This patch splits any VVP net functor that needs to access both
statically and automatically allocated state into two sub-classes,
one for handling operations on statically allocated state, the
other for handling operations on automatically allocated state.
This undoes the increase in run-time memory use introduced when
automatic task/function support was first introduced.
This patch also fixes various issues with event handling in automatic
scopes. Event expressions in automatic scopes may now reference either
statically or automatically allocated variables or arrays, or part
selects or word selects thereof. More complex expressions (e.g.
containing arithmetic or logical operators, function calls, etc.) are
not currently supported.
This patch introduces some error checking for language constructs
that may not reference automatically allocated variables. Further
error checking will follow in a subsequent patch.
