Hi,
I am developing a library that requires avx and fma instructions to be fast, If simd isn't enabled it performs bad and I don't want to implement other versions of my functions without simd. Should I use compiler_error macro to fail compilation if avx and fma isn't enabled or is telling users to enable target-cpu=native is enough?
library is here: https://github.com/oezgurmakkurt/blasoxide
Also It would be great if someone wanted to write non simd versions of functions
Personally I use cfg'd compile_errors. Your library should not allow execution of SIMD intrinsics without compile- or run-time checks of required target feature.
Putting this prevents docs from building also so It wont build on docs.rs, Do you know a solution to this?
For aesni I add the following lines to Cargo.toml:
[package.metadata.docs.rs]
rustc-args = ["-C", "target-feature=+aes,+ssse3"]
rustdoc-args = ["-C", "target-feature=+aes,+ssse3"]
thanks !
