CFI is probably a lot less interesting on archs where you have a
plenty registers not to need to manipulate stack frames in asm
functions, since in that case the debugger mostly works fine without
CFI. I don't know right off which of the other archs have significant
amounts of asm that adjusts the stack pointer, but you could go
through and check them. Having ABI info for them all would be helpful;
I'm pasting my draft ABI reference (which might have errors) below.
