Is there anything in particular that you know is missing?  The only
open issue I know of is multiple locations with overapping live ranges.
Using a location list for the frame base should work.

[But it's not clear how useful making DW_AT_frame_base work from the
first instruction of the function is... the locals are all still
uninitialized anyway.]
