This goes all the way down to the vvp level, where we create support
for arrays of objects, generate the new code in the -tvvp code
generator, and elaborate the arrays in the first place.
When looking for a value change on a part select of an array word,
the callback handle has to save the current value and test it with
the new value to see if there is an actual change. If not, then
suppress the callback.
This patch adds -Wextra to the compilation flags for C++ files in
the vvp and vpi subdirectories. It also fixes all the problems
found while adding -Wextra. This mostly entailed removing some of
the unused arguments, removing the name for others and using the
correct number of initializers.
Create the .var/2u and .var/2s variable records and give them
basic implementations. Make available to VPI the proper types
for the SystemVerilog types that these variables represent.
Support arrays of realtime variable arrays and net arrays. This
involved a simple fix to the ivl core parser, proper support in
the code generator, and rework the runtime support in vvp.
This patch adds non-blocking event control for array words.
It also fixes a problem where the word used to put the
calculated delay for a non-blocking array assignment was
not being released. It also fixes the non-blocking array
assignments to correctly handle off the end/beginning part
selects.
Functions like $monitor need to attach callbacks to array words if
those words are to be monitored. Have the array hold all the callbacks
for words in the array, under the assumption that the monitored words
are sparse.
It is possible for the code generator to create .array/port objects
before the .array object that the port refereces, so use the resolv_list
to arrange for binding during cleanup.
Use the new array VPI functionality (vpiIndex, vpiParent, vpiArray)
to dynamically generate array word names. The old patch to implement
was mostly reverted.
Add the array related VPI calls. These will be used to generate
the array word name only as needed to conserve space. This patch
also makes scanmem3 from the vpi test work correctly after a
slight gold file update.
This patch adds the ability to dump array words. The words are only
dumped if they appear in a $dumpvars() statement (they are not dumped
by default). The name used for the word is <array_name>[<index>], so
you can get unexpected name conflicts.
There is also a slight increase in the memory requirements since each
array word now keeps its own name information. In the future we would
like to change this, but that is a much larger rewrite of the array
code in vvp.
This patch also needs the "Prefix escaped identifier ..." patch to
work correctly (the array word name is an escaped identifier).
