> This fix simplifies the hotspot intrinsics for some platforms and optimizes > the key computation for encryption. We can save the `genInvRoundKeys` > computation when we only do encryption. > > The micro:org.openjdk.bench.javax.crypto.AESReinit benchmark results are > improved by 17% for ppc64 and 26% for x86_64.
