pub enum CpuFeature {

}
Expand description

The nomenclature is inspired by the cpuid crate. The list of supported features was initially retrieved from cranelift-native.

The CpuFeature enum values are likely to grow closer to the original cpuid. However, we prefer to start small and grow from there.

If you would like to use a flag that doesn’t exist yet here, please open a PR.
