Class AArch64ArithmeticOp.ASIMDBinaryTwoStepOp

java.lang.Object

jdk.graal.compiler.lir.LIRInstruction

jdk.graal.compiler.lir.aarch64.AArch64LIRInstruction

jdk.graal.compiler.lir.aarch64.AArch64ArithmeticOp.ASIMDBinaryTwoStepOp

Enclosing class:

AArch64ArithmeticOp

public static class AArch64ArithmeticOp.ASIMDBinaryTwoStepOp
extends AArch64LIRInstruction

For ASIMD, some arithmetic operations require generating two instructions and eagerly use the result register. In this case, the input registers must be marked as ALIVE to guarantee they are not reused for the result reg.
