Gets rid of a few warning: deprecated conversion from string
constant to 'char*', follows IEEE 1364-2001C 27.10 in more cases,
and fixes at least one real bug (look at the previous use of
strdup/strcat in real_var_get_str() and signal_get_str()).
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).
This patch fixes/enhances the array part select code. It also
verifies that any lval array index in a continuous assignment
is a constant value. Also, %set/av now uses index register 1 as
described in the documentation (as a bit offset).
Arrays of nets that have all their words collapsed together can become
a collapsed array as a whole. Add support for this case in the vvp code
generator and runtime.
