There is no such thing as "debug symbols". There are various DIEs (Debug
Information Entries) that can be associated with particular address
ranges though. You might want to read a bit about DWARF at

You might want to take a look at src/addr2line.c which has some code
(print_dwarf_function) to print out some information found in the DWARF
debuginfo associated with a particular address.
