I'm not aware of that specific term but I am aware AIs can be 
specialized for specific domains. I haven't done anything like 
that myself yet.

80 bit floating point is almost completely decoupled from dmd and 
could be implemented in C, I don't see why the AI needs 
D-specific knowledge to write such an emulator. But the idea is 
interesting, and indeed maybe it can help improve the backend's 
debug info emission.

Even without a custom GPT it's already nice that I can ask an LLM 
how DWARF works, and on https://deepwiki.com/dlang/dmd I can ask 
where the DWARF emission is currently implemented in dmd. I 
remember at DConf '22 asking Luís Ferreira about enum member 
debug info generation because online I couldn't easily find info 
on how to do that.

But still, I'd be interested in seeing AI specialized in dmd / D, 
it's just not something I myself plan to look into short term.
