Improve handling of invalid packed and unpacked dimensions.
...
As reported on iverilog-devel on 2018-10-12, a dimension size of zero
could case the compiler to go into an infinite loop. Further tests
showed that unsized or queue dimensions entered as packed dimensions
would cause the compiler to crash.

Fix for br1015 : assertion failure when task/function port is an array.

Support separate compilation units in SystemVerilog.
...
The compilation unit scope is now treated as a specialised form of
package (with an automatically generated name). All items declared
outside a design element are added to the current compilation unit
package. Apart from when searching for a symbol, once we get into
elaboration we can treat these just like any other package.

Reinstate error recovery for range expressions.
...
If an error is found whilst elaborating a range expression in a signal
declaration, create a dummy range and continue elaboration. This stops
the compiler reporting an error every time that signal is referenced.

Fix for br961 - function return type elaborated in wrong scope.

The return type of a function should be elaborated in the context of
the enclosing scope, not in the context of the function itself.

Handle arrays of class objects.
...
This goes all the way down to the vvp level, where we create support
for arrays of objects, generate the new code in the -tvvp code
generator, and elaborate the arrays in the first place.

Partial fix for br956 (various enumeration bugs)

recursively in any parent scope.

Fix internal error elaborating types used in different scopes

Some types, i.e. vector types with parameterized dimensions,
may have different elaboration results in different scopes.
Handle those cases in the elaboration caches.

code generator just sees them as variables.

Fix repeated use of disabled const functions.

If constant functions are exited by a return/disable, fix
the leaked "disable" flag that causes blocks in the next
try at the function to not work.
There are also a lot of debug messages added to help find
this and similar problems.
2013-06-12 14:09:08 -07:00
8994ef1483
Implement class constructors.
...
Class constructors are the "new" method in a class description.
Elaborate the constructor as an ordinary method, but the only
way to access this method is to implicitly call it. The elaborator
will take the constructor call and generate a naked "new" expression
and implicit constructor method call with the object itself as the
return value.
