Debugging dynamic linker

Hello gdb list,
I'm currently trying to debug a dynamic linker I'm writing, and I'm into
code loaded by it. Currently it's not at all obvious how to load symbols
from shared libraries. It seems I need to separately get the load region
for the shared object from `info proc mappings` and also the text section
address from readelf. Is there a way this can be automated or made less
complicated?
Thank you.
