• Record element subtypes are now resolved in packages

LGTM.

@Tcenova do you need this change to be released as v0.29.0 or is a merge to dev branch ok so far?

Currently, dev branch has only a few changes.

[Tcenova]

The dev branch is fine for now. I am waiting on your changes in the standalone branch of ghdl to make there way to master before it would be useful. I have been testing with a combination of branches of things to get type resolution working. Its also possible I may have other pull requests in the future if I implement other missing pieces.

Are you waiting because of the standalone installation feature or because of gathered additions to GHDL?

[Paebbels]

May I asked if the pyVHDLModel is so far understandable. It doesn't have lots of documentation and it might not be easy to understand what I did and how I did it :).

I am mainly waiting on the changes to pyGHDL that allow it to use the latest version of pyVHDLModel. Overall, I am trying to fully parse an entities ports and generics. I have some local code to also resolve subtypes of the ports which is only possible with the latest code. I am also trying to extract the constraints of ports and generics on an entity, hence why I opened ghdl/ghdl#2661

I cant say I have been able to understand the high level approach/reasoning for things yet, but I also haven't spent much time trying. There seems to be many layers, along with more layers added in the DOM in pyGHDL, so traversing through the layers has sometimes been a challenge. I am able to generally understand how to use things after looking at the different layers of source code though.

Oh, ghdl/ghdl#2661. I didn't recognize your name from there. Sorry.

I'll try to invest more time into it. (pending PR: ghdl/ghdl#2439)
