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.
