--- Comment #16 from Frank Ch. Eigler <fche at redhat dot com> ---
Sorry about the confusion, it was mine.

Yeah, libbfd.so's dependencies are small, adding debuginfod (=> libcurl) would
make it rather larger.  OTOH elfutils-libs are on systems already, so the
dependencies would not make system install images larger.

As an architectural question, I suspect it'd be more of an objdump side change
rather than a bfd one, given that bfd doesn't deal with source code.

(OTOH bfd/opencls.c has debuginfod-analogous lookup (hard-coding the
/usr/lib/.build-id/XXX convention).  It could fall back to a debuginfod query
via spawning an external debuginfod-find process, if the EXTRA_DEBUG_ROOT1
searches fail.  Any idea why we thought putting the code into binutils/dwarf.c
instead was the right place for the hook?)
