What exactly does "info sharedlibrary" command show?

Hi, all

Recently I'm looking for a proper method of finding the memory usage
of shared library of a specific program, and from the manual of GDB, I
found "info sharedlibrary" command.

However, I'm curious about the display of its result. Does anyone know
the meaning of memory address reported by GDB? Something like:
============

From To Syms Read Shared Object Library
0x005cfc00 0x006bf800 Yes /lib/tls/libc.so.6
0x0059e7a0 0x005b010f Yes /lib/ld-linux.so.2

============
I believe they are not the physical address, right?

If they are virtual memory address, why they are different from the
info from /proc/{PID}/maps? the {PID} is the specific program process
ID.

============
Contents of "maps"

0x0059e000 0x005b3000 r-xp 00000000 fd:00 3605642 /lib/ld-2.3.4.so
0x005b3000 0x005b4000 r--p 00014000 fd:00 3605642 /lib/ld-2.3.4.so

Thanks in advance!
