What were you trying to do that didn't work?

I'm looking at info share as a way to obtain the load address of shared objects. This data is helpful to make sense of addresses if shared objects lack debugging information. Having a convenient command for this helps in support scenarios.

Please provide the package NVR for which bug is seen:

gdb-10.2-11.el9.x86_64

How reproducible:

Always.

Steps to reproduce

1. gdb -p $$
2. info share
3. print/x _rtld_global._dl_rtld_map.l_addr

Expected results

info share prints the page-aligned load address of shared objects.

Actual results

(gdb) info share
From                To                  Syms Read   Shared Object Library
0x00007f2d5b58d570  0x00007f2d5b59a05c  Yes (*)     /lib64/libtinfo.so.6
0x00007f2d5b228700  0x00007f2d5b39b1ed  Yes         /lib64/libc.so.6
0x00007f2d5b5be090  0x00007f2d5b5e3ac3  Yes         /lib64/ld-linux-x86-64.so.2
(*): Shared library is missing debugging information.
(gdb) print/x _rtld_global._dl_rtld_map.l_addr
$2 = 0x7f2d5b5bc000

Note how the load addresses of the shared objects are not page-aligned.
