### Selecting Additional Target Features
|
||||
|
||||
If you want to enable support for a target feature within your build, generally you should use a [target-feature](https://rust-lang.github.io/packed_simd/perf-guide/target-feature/rustflags.html#target-feature) setting within you `RUSTFLAGS` setting.
|
||||
If you want to enable support for a target feature within your build, generally you should use a [target-feature](https://rust-lang.github.io/packed_simd/perf-guide/target-feature/rustflags.html#target-feature) setting within your `RUSTFLAGS` setting.
|
||||
|
||||
If you know that you're targeting a specific CPU you can instead use the [target-cpu](https://rust-lang.github.io/packed_simd/perf-guide/target-feature/rustflags.html#target-cpu) flag and the compiler will enable the correct set of features for that CPU.
