Stephen Williams 3c2fb6a601 Fix dynamic array assignment to make a copy of the rvalue. 
IEEE Std 1800-2017 Section 7.6 Array assignments

Assignment of a dynamic array creates a duplicate of the source,
so that assignments to the copy don't impact the original. Handle
all sorts of dynamic array base types.

Cary R d6b6b76015 Update header files to use a more standard name to prevent rereading 
This is from github report #16. There are likely a few more issues
that need to be addressed though this takes care of the major ones.

Stephen Williams 860419a346 Draft run-time support for SystemVerilog class objects. 
This provides the ivl_target.h interface for class definitions
and expressions, the vvp code generator support for class objects
and properties, and the vvp run time support. Trivial class objects
now seem to work.

Stephen Williams e7c6829512 Create a stub vvp_cobject class. 2012-12-10 19:13:43 -08:00
Stephen Williams a186e5ad31 Garbage collection of DARRAY and CLASS objects. 
While we're at it, provide a stub class_new runtime.

Stephen Williams 0059fb1ec7 Support for dynamic arrays of strings. 
Strings, when put into dynamic arrays, are treated as first class
types much line reals. Add the code generator and vvp support for
this situation. Also fix a bug distinguishing between character
selects from strings and select form arrays of strings.

Stephen Williams d6efece5dd Handle DARRAYs of real variables 
This involves working out the code to get the base type of a select
expression of a darray. Also added the runtime support for darrays
with real value elements.

Stephen Williams 94e217f02b vvp support for dynamic arrays. 
This words completely for single-dimension dynamic arrays of
32bit integers. These changes also act as a stub for other
target types.

Stephen Williams d0e6b24ca2 Support the new[] operator for arrays 
Implement through the ivl core to the ivl_target.h API.
Also draft implementation of creating and storing arrays
in the vvp runtime and code generator.

Stephen Williams 14f229de30 Parse support for dynamic arrays. 
This includes limited support for dynamic arrays down to the code
generator, and some stubs in the vvp code generator and vvp run time.
