Struct VCodeGenerator 

pub struct VCodeGenerator<I, S>
where
    S: InstructionSelector<Instruction = I>,
    I: Instr,
{ /* private fields */ }

VCodeGenerator is an internal structure used to generate VCode for a given backend.

Implementations

impl<I, S> VCodeGenerator<I, S>

where S: InstructionSelector<Instruction = I>, I: Instr,

pub fn get_vreg(&mut self, value: Value) -> VReg

Gets the VReg associated with the given Value.

pub fn new_unassociated_vreg(&mut self) -> VReg

Creates a new VReg that is unassociated with any Value.

pub fn func_map(&self) -> &HashMap<FunctionId, usize>

Returns the map from IR FunctionIds to indexes into the VCode’s list of functions.

pub fn label_map(&self) -> &HashMap<BasicBlockId, usize>

Returns the map from IR BasicBlockIds to indexes into the current function’s list of labels.

pub fn push_prelabel_instruction(&mut self, instruction: I)

pub fn push_prereturn_instruction(&mut self, instruction: I)

pub fn push_instruction(&mut self, instruction: I)

Pushes an instruction into the VCode being generated.
