--- Comment #29 from Martin Liska <mliska at suse dot cz> ---
Thanks for the implementation. However, I think one piece is missing and it's
find_separate_debug and find_separate_debug rely on fact the debugginfo is
present for a abfd, but can't load it from debuginfod:

$ DEBUGINFOD_VERBOSE=1
/home/marxin/Programming/binutils/objdir/binutils/objdump -S `which true`
(does not get any source file)

while installing coreutils-debuginfo (and *not* coreutils-debugsource) I get:

$ DEBUGINFOD_VERBOSE=1
/home/marxin/Programming/binutils/objdir/binutils/objdump -S `which true`
