Thanks, that wasn't too hard at all indeed. I added support for
DW_OP_call_frame_cfa to systemtap now.
I committed the trivial patch to make getlocation not barf.
For completeness, should it also include DW_OP_form_tls_address
(although gcc seems to emit DW_OP_GNU_push_tls_address) and
DW_OP_bit_piece (which gcc doesn't seem to emit)?
