Methods

impl TransformGroupBuilder

pub fn new(name: &'static str, doc: &'static str) -> Self

pub fn chain_with(self, next_id: TransformGroupIndex) -> Self

pub fn isa(self, isa_name: &'static str) -> Self

pub fn custom_legalize(
    &mut self,
    inst: &Rc<InstructionContent>,
    func_name: &'static str
)

Add a custom legalization action for inst.

The func_name parameter is the fully qualified name of a Rust function which takes the same arguments as the isa::Legalize actions.

The custom function will be called to legalize inst and any return value is ignored.

pub fn legalize(&mut self, src: DummyDef, dst: Vec<DummyDef>)

Add a legalization pattern to this group.

pub fn build_and_add_to(
    self,
    owner: &mut TransformGroups
) -> TransformGroupIndex
