bitops.h:209:9: error: 'asm goto' constructs are not supported yet

I tried to build the hello_world example and it failed.

I followed the instructions:

export PATH=/home/loongson/.cargo/bin:$PATH;
rustup component add --toolchain=nightly rust-src
rustup component add rustfmt-preview
cargo install cargo-edit
cargo install cargo-xbuild

I would like to add I tried this on fedora rawhide. Same error.

[geofft]

Hi @omac777 - on newer kernels (5.0 or newer), you need LLVM 9 or later for support for "asm goto".

By the way, the build code in this project as well as the hello-world module comes from our project at https://github.com/fishinabarrel/linux-kernel-module-rust , which is actively developed. You may have better luck trying the version there, we have since added compatibility with more kernel versions (as well as a bit more functionality).
