Struct IsaBuilder

pub struct IsaBuilder<T> { /* private fields */ }

Builder for a TargetIsa. Modify the ISA-specific settings before creating the TargetIsa trait object with finish.

Implementations

impl<T> IsaBuilder<T>

pub fn new( triple: Triple, setup: Builder, constructor: fn(_: Triple, _: Flags, _: &Builder) -> T, ) -> IsaBuilder<T>

Creates a new ISA-builder from its components, namely the triple for the ISA, the ISA-specific settings builder, and a final constructor function to generate the ISA from its components.

pub fn from_target_isa( target_isa: &dyn TargetIsa, ) -> IsaBuilder<Result<Arc<dyn TargetIsa>, CodegenError>>

Creates a new Builder from a TargetIsa, copying all flags in the process.

pub fn triple(&self) -> &Triple

Gets the triple for the builder.

pub fn iter(&self) -> impl Iterator<Item = Setting>

Iterates the available settings in the builder.

pub fn finish(&self, shared_flags: Flags) -> T

Combine the ISA-specific settings with the provided ISA-independent settings and allocate a fully configured TargetIsa trait object. May return an error if some of the flags are inconsistent or incompatible: for example, some platform-independent features, like general SIMD support, may need certain ISA extensions to be enabled.
