Stephen Williams 819770a6c4 Handle enumerations as packed struct/union members. 
There were also some subtleties related to using enumerations
from typedefs and using them in multiple places. Fix various
bugs related to those issues.

Stephen Williams 20ee350601 Generalize user defined function return type handling. 
I'm gonna need functions to return class objects, so generalize
the output types of user defined functions.

Stephen Williams 914ebeca4a Some rework to allow for nested packed types. 
This also simplifies the NetNet set of contructors and generalizes
the types that are supported, especially packed types.

Stephen Williams 0bdabab4fb Rework packed dimensions handling 
Make packed structs more obviously parts of a vector.
Handle arrays of structs in certain cases.

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.

Cary R 3b6e26aa90 An enumeration cannot have duplicate values. 
Add code to check that an enumeration does not have duplicate values.

Cary R b2ebc29c5a Fix some enum bugs. 
This patch fixes a few more bugs in the enumeration code.

It add support for saving the file and line information to make
diagnostic messages better.

It updates some of the compiler warning messages to use the file
and line information.

It passes if the enumeration type is signed all the way to the
code generators.

It fixes the parser to correctly have the range after the signed
designation for the vector types.

It adds a warning that vvp does not currently support a negative
two state enumeration value.

Stephen Williams de215f1f8d Describe enum type to code generators 
This gets the enumeration type through to the ivl_target API so
that code generators can do something with it. Generate stub
output with tgt-stub, and generate the proper vvp run time to
make simple enumerations work from end to end.

Stephen Williams 5e2c0e5d04 Better handling of width of enum literals in expressions. 2010-11-07 09:58:00 -08:00

Stephen Williams 5b5a6b05b7 Test type correctness during elaboration. 
Create a netenum_t class to carry the enumeration type in the
netlist.h structures, and use that type to check enumerations
with assignments.
