-----------------------------
The loadable target module API is starting to take shape.
That is the major thrust nowadays with Icarus Verilog, after all, so
progress is being made here. The biggest change is in fact a philosophy
change. The target module now needs only a single symbol -- target_design --
to receive the whole design. The target module can from there and using
the API access the entire design randomly. So if you wanted to implement
a graphical browser, you could:-)
I've added support for the l-values of procedural assignments, and also
back pointers to objects that reference ivl_nexus_t objects. This closes
the loop so that there should be no dead-ends in the design.
I've clarified and expanded the descriptions in the ivl_target.h header
file. There should be just about enough documentation to properly used
all the various types. (Have any of you tried to write GIMP plug-ins?
Have you looked at the libgimp header files? Have you seen any comments
there?-( I won't ever sink to that level, I hope.)
I've also imtegrated updates to the Cygwin32 port to support loadable
targets under Cygwin32. After much struggling, Venkat managed to discover
the secret magic needed to get load time symbol binding to work. Hopefully
I didn't break it too bad when I changed the API again. (I think it is
still fine.)
