org.graalvm.compiler.lir.aarch64.AArch64LIRInstruction

org.graalvm.compiler.lir.aarch64.AArch64ArrayCompareToOp

public final class AArch64ArrayCompareToOp
extends AArch64LIRInstruction

Emits code which compares two arrays lexicographically. If the CPU supports any vector instructions specialized code is emitted to leverage these instructions.

IMPORTANT: If both array kinds are not the same (i.e., one is a Char array and another is a Byte array), then byte array's value and length will be the first passed value and the char array's value and length will be the second passed value; however, even if the inputs are swapped, kind1 and kind2 will be in the original order. See AArch64GraphBuilderPlugins registerStringLatin1Plugins and registerStringUTF16Plugins for the arrangement of values.
