Not that I know of.

I have been looking thoughtfully at Ultibo:

It is a bare-metal FreePascal development environment for the RasPi 1 to 3B.

I have not actually tried to build anything yet and my Pascal skills
are 30y rusty now (and they were never that great anyway, but they're
better than my C skills ever were).

I believe it is possible to get Ultibo to load and execute a
monolithic ARM binary, so long as it meets some requirements. I was
pondering trying to built a statically-linked executable of Aranym:

Aranym already runs on the RasPi using Rasbian:

But by the same token it ought  to be possible to do this with SimH or
anything else...
