Constructor Detail

NHIRPhiFunction

public NHIRPhiFunction(NBasicBlock block,
               int id,
               ArrayList<Integer> arguments,
               int local)

Construct an NHIRPhiFunction instruction.

Parameters:

block - enclosing block.

id - identifier of the instruction.

arguments - list of HIR ids of arguments for the phi function.

local - local variable index.

Method Detail

inferType

public void inferType()

Infer type for this phi function. It is essentially the type of the arguments.

toLir

public NLIRInstruction toLir()

Description copied from class: NHIRInstruction

Convert and return a low-level representation (LIR) of this HIR instruction. Also adds the returned LIR instruction to the list of LIR instructions for the block containing this instruction, along with any other intermediate LIR instructions needed.

Overrides:

toLir in class NHIRInstruction

Returns:

LIR instruction corresponding to this HIR instruction.

toString

public String toString()

Description copied from class: NHIRInstruction

Return a string representation of this instruction.

Overrides:

toString in class NHIRInstruction

Returns:

string representation of this instruction.
