Constructor Detail

BinaryOpInstruction

public BinaryOpInstruction(SSAValue result,
                           BinaryOp op,
                           Value left,
                           Value right)

Creates a binary operation and registers uses of its SSA operands.

Parameters:

result - the SSA value receiving the result

op - the operation to perform

left - the left operand

right - the right operand
