public interface ArithmeticLIRGenerator

This interface can be used to generate LIR for arithmetic operations. The setFlags flag in emitAdd, emitSub and emitMul indicates, that the instruction must set the flags register to be used for a later branch. (On AMD64, the condition codes are set in every arithmetic instruction, but other architectures optionally set the flags register) If setFlags is set, the instruction must set the flags register; if false, the instruction may or may not set the flags register.
