I see that other packages use gold as well (e.g. qtbase-opensource-src),
codesearch.d.n turns up quite a few more.
Are you sure that this only affects systemd?

Or is this specific due to the usage of LTO or the usage of other
specific features? If so, have you checked which one that are and if
that affects other packages as well?

I understand that fixing binutils might take some time. Then again, the
gold linker on sparc has been known broken for over a year, so I don't
quite get the sudden hurry (i.e. escalating this within 3 days without
giving us a chance to respond, especiallly since I've been away over the
weekend. I have to say I'm quite disturbed by that. But let's leave it
at that)

I'm also not convinced yet that applying this workaround to systemd is
the only available option and the correct one we should use.

If other packages are affected as well, it sounds to me that we should
rather add a workaround to binutils until a proper solution has been
developed.

If it's only systemd, by all means let's merge that patch. But so far, I
haven't seen a thorough assessment of this issue which would have
convinced me in that direction.
We certainly don't want to obstruct any efforts you do on the sparc
port, but let's first be certain that this workaround is the proper one.


Regards,
Michael
