https://bugzilla.redhat.com/show_bug.cgi?id=2109340 --- Comment #5 from Carl George 🤠 <carl@xxxxxxxxxx> --- > SSE2 is enabled by default, however my understanding is that AVX2 and NEON are not. >From an x86_64 build log: checking for --disable-sse2... no checking for --disable-avx... no >From an aarch64 build log: checking for --disable-sse2... no checking for --disable-neon... no They look to be enabled by default to me, since a flag to disable them is available and checked for during compilation. Since this isn't a noarch package, each architecture-specific build of ugrep will have the features that architecture supports. > Rust packages seem to provide different options when intrinsics are used, se for example Those rust packages are not doing anything different with compilation. They are nearly empty meta-packages that map to crate "features", which is a way to specify optional dependencies. The aarch64_neon and avx2_backend names are just feature names that other rust software can depend on. https://doc.rust-lang.org/cargo/reference/features.html https://github.com/rusticstuff/simdutf8/blob/v0.1.4/Cargo.toml#L35 https://github.com/dalek-cryptography/curve25519-dalek/blob/3.2.1/Cargo.toml#L74 > Updated the copr package at https://copr.fedorainfracloud.org/coprs/fed500/RE-flex/ to have dynamically linked libraries: That's great, but ugrep still doesn't have a way to link against a shared reflex library. Thus it is allowed by the package guidelines to leave it bundled: "All packages whose upstreams have no mechanism to build against system libraries MAY opt to carry bundled libraries, but if they do, they MUST include an indication of what they bundle." https://docs.fedoraproject.org/en-US/packaging-guidelines/#bundling -- You are receiving this mail because: You are on the CC list for the bug.
