What about the ".pdr" section?
I get the feeling that core GDB has another really useful table just
beyond its fingertips - the unwind table - and that can be used to find
things like map from a pc to the function start/end/name/...:
- PPC64 has a traceback table just past the end of the function and that
can provide a pointer (tb_offset) back to the function's start
- For ia64, it must have similar (for that binary search to work)
- For MIPS there's this PDR section and it appears to have the function
start as well.
