Remove commented out do_assign.
Remove useless operator=.
Support evaluating + operator at compile time.
Handle display of odd octal/hex widths (Eric Ardoom)
Add Octal dump format.
Structural case equals device.
Support parameters in continuous assignments.
Better message for combinational operators.
support XNF OBUFT devices.
Proper support for XNF synthesis.
Support + in constant expressions.
Add the %t formatting escape.
Start line directives with newline.
Accept adder parameters with different widths,
and simplify continuous assign construction.
Fix too many -t with -t flag.
support the -t switch.
vvm supports unary | operator.
Fix dump of sase statements.
Add non-const bit select in l-value of assignment.
Move the rvalue into NetAssign_ common code.
The $finish task should work immediately.
== and != connected to the wrong pins of the compare.
Add support for reduction NOR.
Relaxed width handling for <= assignment.
null target ignore assignment nodes.
sorry message for non-constant l-value bit select.
Add some vvm operators from Eric Aardoom.
More resilient assignment to memory location.
Rewrite vvm output to separateclass declarations
from method definitions. This is required to allow
for mutual referencing, for example by tasks.
Handle mutual reference of tasks by elaborating
task definitions in two passes, like functions.
Ignore user task definitions.
Remember to declare the calee_ member.
catch non-constant delays as unsupported.
