Good to know! I'm particularly interested in getting simple backtraces
(just the addresses from each called function should suffice) from
running applications using libunwind's ptrace support. Do you know
whether is this possible with .debug_frame information generated by
latest CodeSourcery ARM toolchains? Is there any public snapshot where
one could get current work on dwarf-2 support for ARM?
Sorry if this may sound a bit OT to this list.
