            Bug ID: 25588
           Summary: Documentation inaccurate for directories searched when
                    a shared library is requiring another
           Product: binutils
           Version: 2.34
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: ld
          Assignee: unassigned at sourceware dot org
          Reporter: pierre.labastie at neuf dot fr
  Target Milestone: ---

The documentation (both in man and info form) under -rpath-link=DIR states:
           The linker uses the following search paths to locate required
           shared libraries:

           1.  Any directories specified by -rpath-link options.
[...]
           8.  For a native linker on an ELF system, if the file
               /etc/ld.so.conf exists, the list of directories found in that
               file.

Actually, studying the code of ldelf.c, I understand that it is
<sysroot>/<prefix>/etc/ld.so.conf or <sysroot>/etc/ld.so.conf which is used.
Furthermore, if all that fails, it falls back to using the search path of the
ld script (or another search path, I am not sure: it uses the "search_head"
variable, which may be modified by using a pointer to it, so not easy to follow
statically). So I think the doco should have a point:
          9.  On an elf system, falls back to use the search path of....
