This commit is
|git describe --contains 799587d5731db9dc
|v5.7-rc7~32^2~2

and CI said:
|head:   d012a7190fc1fd72ed48911e77ca97ba4521bccd
^^ v5.9-rc2
|commit: de8f5e4f2dc1f032b46afda0a78cab5456974f89 lockdep: Introduce wait-type checks
^^ v5.7-rc1

so my assumption was that it tested rc2 and bisected it down to that
commit. Otherwise I don't see the point in testing such an old commit on
a recent -rc2 and complaining about things not related to one another.

Sorry for that. It is

This is the one built by Arnd and hosted at

Is it suitable for testing?

You know probably best :)

Is a switch missing while building the gcc, another gcc target needed or
is this something that is not part of upstream gcc?

but it shouldn't complain about a commit merged in v5.7-rc1 because it
caused an error which was then fixed in v5.7-rc7 while using HEAD
v5.9-rc2?

You are welcome.
