Enum wasmer_compiler::CpuFeature

pub enum CpuFeature {
    SSE2,
    SSE3,
    SSSE3,
    SSE41,
    SSE42,
    POPCNT,
    AVX,
    BMI1,
    BMI2,
    AVX2,
    AVX512DQ,
    AVX512VL,
    LZCNT,
}

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.
