But I also don't see these build errors. I'm using the same HEAD commit. I think the
same .config (derived from arch/ia64/configs/bigsur_defconfig.
Big difference is I'm doing a natinve build with a much older compiler (4.6.4)

I was able to reproduce the build errors.
using gcc 8.1.0 cross-compile.

Hi Tony!

Just as a heads-up: There are updated installation images available
for Debian unstable for ia64 [1]. Those install a fresh system using GRUB
as a bootloader and come with the latest versions of the toolchain.
Please keep in mind that the kernel is currently unbootable on some machines
due to a miscompiled kernel due to a bug in gcc-8 [2]. However, there is already
a fix for this particular gcc bug and it has also been backported to gcc-8 as
of yesterday, so we're just waiting for Debian's gcc-8 package to be updated
so we can rebuild the kernel packages and the installation image.
The network mirror and remote directory which are being prompted for during
installation are:
- Mirror: http://ftp.ports.debian.org
- Directory: debian-ports
Thanks,
Adrian

Do we also have an x86 to ia64 cross compiler package for Debian?
Those packages really help me with changes to other architectures, and
the lack of them for ia64 makes compile-testing ia64 code rather painful.

Hmm, I just realized that building the cross-compiler for ia64 is disabled
at the moment because we were having issues with libunwind back then. But
normally, on Debian and Ubuntu, you can just install the compiler with:
# apt install gcc-8-$ARCH-linux-gnu
And that should also be the case for ia64, hence I will look into fixing this
as it should have been long time ago. Thanks for the reminder.

Yes, and I've done that for all other architectures available, it is
just ia64 that has been missing.
