- Subject: handling DW_OP_call_frame_cfa
Hi,
What would be the plan to handle DW_OP_call_frame_cfa? Should
dwarf_getlocation() just return it (as in the patch below) and let the
caller deal with it through dwarf_getcfi(), dwarf_cfi_addrframe() and
dwarf_frame_cfa()? Or should dwarf_getlocation() be extended to do some
of this magic for the caller?
Thanks,
Mark
