Can DWARF2 CFI represent a static return location?

[Alan Lehotsky]

I'm looking at a machine with limited stack, and no push instructions or displaced-addressing mode.  The call instruction stores the return address in the link register.

For non-recursive functions we save the return address in a static memory location, but I can't find a way to tell the DWARF2 CFI that the saved location is a static MEM rtx.  Am I missing something?
