🔬 This is a nightly-only experimental API. (rustc_private)

this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml instead?

Add target_feature = "..." cfgs for a variety of platform specific features (SSE, NEON etc.).

This is performed by checking whether a whitelisted set of features is available on the target machine, by querying LLVM.
