Struct cranelift::prelude::isa::EncInfo

pub struct EncInfo {
    pub constraints: &'static [RecipeConstraints],
    pub sizing: &'static [RecipeSizing],
    pub names: &'static [&'static str],
}

Information about all the encodings in this ISA.

Fields

constraints: &'static [RecipeConstraints]

Constraints on value operands per recipe.

sizing: &'static [RecipeSizing]

Code size information per recipe.

names: &'static [&'static str]

Names of encoding recipes.

Methods

impl EncInfo

pub fn operand_constraints(
    &self,
    enc: Encoding
) -> Option<&'static RecipeConstraints>

Get the value operand constraints for enc if it is a legal encoding.

pub fn display(&self, enc: Encoding) -> DisplayEncoding

Create an object that can display an ISA-dependent encoding properly.

pub fn byte_size(
    &self,
    enc: Encoding,
    inst: Inst,
    divert: &RegDiversions,
    func: &Function
) -> u32

Get the precise size in bytes of instructions encoded with enc.

Returns 0 for illegal encodings.

pub fn branch_range(&self, enc: Encoding) -> Option<BranchRange>

Get the branch range that is supported by enc, if any.

This will never return None for a legal branch encoding.

Trait Implementations

impl Clone for EncInfo

fn clone(&self) -> EncInfo

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
