I have here gcc 10 and the output is:

the reason is that:

I suppose this is mainline gcc 10 ? Although it doesn't seem like compiler version
related.

Indeed this is a problem I can reproduce. Enabling CONFIG_EZNPS_GIC on a non
ARC700 build causes the issue: the ctop header is inside platform code
(arch/arc/plat-eznps/include/plat/ctop.h) which obviously fails if not building
for ARC.

My solution is to move ctop.h to include/soc/nps/plat/.

This is unrelated since original .config with CONFIG_ARC_PLAT_EZNPS would have
selected Big endina build, but you need a BE toolchain to get that working (since
libgcc emulation code still comes from toolchain).

Nothing to update in CI. I'll send the ARC patch as a follow up.

This is unrelated since original .config with CONFIG_ARC_PLAT_EZNPS would have
selected Big endina build, but you need a BE toolchain to get that working (since
libgcc emulation code still comes from toolchain).

The error above was fixed back in April:
799587d5731db9dc ("ARC: [plat-eznps]: Restrict to CONFIG_ISA_ARCOMPACT")

I suppose this is mainline gcc 10 ? Although it doesn't seem like compiler version
related.

Indeed this is a problem I can reproduce. Enabling CONFIG_EZNPS_GIC on a non
ARC700 build causes the issue: the ctop header is inside platform code
(arch/arc/plat-eznps/include/plat/ctop.h) which obviously fails if not building
for ARC.

My solution is to move ctop.h to include/soc/nps/plat/.

This is turning out to be rat's nest. That header when moved causes other issues.
I don't have time to clean up all the mess so I'll just fix it up by doing the
minimal change.

This commit is

|v5.7-rc7~32^2~2

and CI said:

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.

Yeah, as I said this is not specific to compiler version, just the combination of
build options which trigger it.

You need a ARC gcc toolchain configured for big endian builds (actually the
compiler driver can handle both, but support libs such as libgcc need to be BE/LE
built either through multilib or cleanest is to have a ARC gcc configured for
big-endian. Everything is upstream.

Yeah this indeed is weird, the only explanation I can think of is the rand config
triggered the issue now.

/me confused and a bit out of context here. I didn't see the original CI report
