I will sum up the discussion so far on this and other tickets:
When one distributes source code software packages, the developers directly or
indirectly use AR to create static libraries, when the user wan

Why isn’t liblto_plugin.so tweaked to claim only the GCC LTO files, it can
handle? E.g. liblto_plugin.so from GCC7 does not claim files for GCC 8 LTO?
I do not get the conclusion here:
* liblto_plugin.so

At https://gcc.gnu.org/bugzilla/show_bug.cgi?id=70345#c4 is written that “Right
now the plugin from any gcc can be used with any gcc.” This is not the same as
the last comment. Please clarify again, if an

According to https://gcc.gnu.org/bugzilla/show_bug.cgi?id=70345#c4 it does not
matter whether liblto_plugin.so.0.0.0 from GCC7 or 8 is installed under
$libdir/bfd-plugins: both work for both compiler versio

Yes, $(libdir)/bfd-plugins is a location automatically scanned by ar/nm/ranlib.
The question is, why GCC’s “make install” does not put there its linker plugin.
As long as nobody installs the linker plugins

gcc-ar always uses the latest plugin:
