Struct lucetc::CpuFeatures

pub struct CpuFeatures { /* fields omitted */ }

An x86-specific configuration of CPU features that affect code generation.

Methods

impl CpuFeatures

pub fn new(
    cpu: TargetCpu,
    specific_features: HashMap<SpecificFeature, bool>
) -> Self

pub fn detect_cpuid() -> Self

Return a CpuFeatures that uses the CPUID instruction to determine which features to enable.

pub fn baseline() -> Self

Return a CpuFeatures with no optional features enabled.

pub fn set(&mut self, sf: SpecificFeature, enabled: bool)

pub fn isa_builder(&self, target: Triple) -> Result<Builder, Error>

Return a cranelift_codegen::isa::Builder configured with these CPU features.
