Actually I was looking more at the Call Frame Information than the
DW_AT_frame_base; although that does lead me to ask how the two relate,
since they both seem to be giving some of the same information. Does it ever
make sense to have both?
The reason I am looking at Call Frame Information is that we want to
describe how registers are saved on stacks during a call. Extending
DW_AT_frame_base might help with finding variables on the stacks, but I
think we need call frame style information to be able to do a full job of
unwinding the stacks.
