--- Comment #3 from Ben Woodard <woodard at redhat dot com> ---
Nick I may be doing something wrong but I'm not able to reproduce fche's
success. It appears like it is following those links which is good but it
doesn't appear to be successfully using them:

Latest trunk with your patch:

$ ~/bin/objdump  --dwarf=loc,follow-links /lib64/libboost_system.so.1.69.0

vs standard fedora32 version of objdump:

$ objdump  --dwarf=loc --dwarf=follow-links /lib64/libboost_system.so.1.69.0 
/lib64/libboost_system.so.1.69.0: Found separate debug info file:

/lib64/libboost_system.so.1.69.0:     file format elf64-x86-64

To make it clearer:

$ objdump  --dwarf=loc --dwarf=follow-links /lib64/libboost_system.so.1.69.0 >
foo
$ ~/bin/objdump  --dwarf=loc --dwarf=follow-links

It gets the DWZ file now but I still don't get the location lists that I'm
looking for.
