Hello,
now that all pieces of the DWARF-2 CFI rework have gone in, and
the big s390 backend reorganization was also committed, this patch
is the only thing that's missing to enable DWARF-2 frame support
on s390.
Do you think a copyright assignment is required for this? While
it's longer than 10 lines, it doesn't really contain anything
that should be significant w.r.t. intellectual property -- the
s390_dwarf2_frame_init_reg routine only implements the publicly
documented s390 ABI calling convention ...
