JALR gets the upper 20 bits from a general purpose register and it includes 12 low bits in its instruction encoding. I know almost nothing about rv32, but is this what you mean by a Large Memory Model, the use of the JALR instruction? I didn't find the part that talks about how JALR works in rv64, but it seems likely it can specify an arbitrary 64-bit address?

yep.
