[NF] Frontend sets all non-connectors variables and parameters to DAE.POTENTIAL

[Adrian Pop]

The NF sets all variables and parameters to DAE.POTENTIAL (even if they are not connectors), of course if they are not stream or flow.

Because of this BackendVariable.calcAliasKey will be different with the NF as it uses isVarConnector which checks for DAE.NON_CONNECTOR (which is never generated by the NF).

If you implement this, remember that connectors can contain records. I.e. it's not always the immediate parent of a component that determines whether it's a potential or non-connector variable.

Yes. You need to go up the instance hierarchy and see that none of them are connectors. I use NFTyping.checkConnectorType to check if node is a connector or not.

Replying to adrpo:

Sure, it's slightly inefficient since it won't stop until it finds a connector or runs out of parents, but it works.

Should be fixed with PR: ​https://github.com/OpenModelica/OMCompiler/pull/2930
@perost: please have a quick look on this.
