Clearly it doesn't yet work. I see dwarf2out_do_eh_frame is also used as gate for the "dwarf2" pass. That probably should use per-function settings then, thus an alternate predicate? Because the global setting simply tells the assembler to either emit everything into eh_frame or debug_frame (seems the assembler cannot have different settings on a per function basis?). So I guess an appropriate cleanup would be to pass a struct function to dwarf2out_do_eh_frame but also deal with it being NULL?
