Hello,
I'm not sure, should this branch compile on ARM Devices?
I've tried Raspbian 32bit and Ubuntu Core 64bit.
All necessary libs are installed.

I got exactly the same error with gcc 8/9/10 on a raspberry pi 4 running
Debian buster/Sid and fedora 31/rawhide in podman container.
It seems in gccjit issue as the hello world example on gccjit doc web site
does not compile on raspberry pi 4 as well

I've built many times on aarch64 but not in the last weeks and always
with a libgccjit compiled form source. Still have to try aarch32.

Just curious... how long does it take to compile gcc & emacs native on your
aarch64 machine? I have never successfully get it done on a Rpi4b...

Aarch64 can be quite satisfying for compiling depending on the machine.
On the one I used speed 2 compile time was about 100min (64 cores),
newer generations should be faster.
Anyway configuring libgccjit with "--enable-host-shared
--enable-languages=jit --disable-bootstrap --enable-checking=release"
makes compilation surprisingly cheap.
And regarding Emacs
make NATIVE_FAST_BOOT=1 BYTE_COMPILE_EXTRA_FLAGS='--eval "(setq comp-speed 0)"'
Is the recipe to start with on constrained HW. On "normal" machines it
completes in ~10 min so should be sustainable on any system.
