v1.19.2 compiles fine.

The issue can be reproduced via:

# somehow install zig https://ziglang.org
cargo install --locked cargo-zigbuild
# on Arch Linux the above two commands can be replaced with: pacman -S zig cargo-zigbuild

git clone https://github.com/adamkewley/libdeflater
cd libdeflater/libdeflate-sys
git submodule init
git submodule update
cargo zigbuild --release --target aarch64-unknown-linux-gnu
# same applies for the musl target: cargo zigbuild --release --target aarch64-unknown-linux-musl

I was able to bisect the regression to ebiggers/libdeflate@c1926a4

Hi,

I'm quite busy and won't be able to investigate the exact reason for this regression. Based on what you're reporting, it looks like upstream has added support for some native instructions that aren't compatible with the way you would like to build libdeflater (i.e. via the zig compiler, rather than gcc?)

via the zig compiler, rather than gcc?

Yes cargo-zigbuild is supposed to make it easier to cross compile by having zig replace gcc/clang.

I'm not in a hurry to fix this and I'll try spending some time myself to understand how it works under the hood and how to reproduce it without all of the surrounding Rust stuff.

Fair enough!

No idea exactly what this could be but, looking at the error message and the symbols involved (which are typical SIMD intrinsics you'd find in a C codebase that's using immintrin) my guess would be that the zig compiler doesn't like the intrinsics.

To be fair to zig, intrinsics are quite tricky to get right without UB etc. (they tend to rely on programmers being very aware of memory alignment, register state, etc.), so it wouldn't surprise me if there's some kind of restrictions on their use!
