This patch set encompasses the following commits: - Adds a new HotSpot intrinsic candidate to the java.lang.Base64 class - decodeBlock(), and provides a flexible API for the intrinsic. The API is similar to the existing encodeBlock intrinsic. - Adds the code in HotSpot to check and martial the new intrinsic's arguments to the arch-specific intrinsic implementation - Adds a Power64LE-specific implementation of the decodeBlock intrinsic. - Adds a JMH microbenchmark for both Base64 encoding and encoding. - Enhances the JTReg hotspot intrinsic "TestBase64.java" regression test to more fully test both decoding and encoding.
------------- Commit messages: - Expand the Base64 intrinsic regression test to cover decodeBlock - Add JMH benchmark for Base64 variable length buffer decoding - Add Power9+ intrinsic implementation for Base64 decoding - Add HotSpot code to implement Base64 decodeBlock API - Add HotSpotIntrinsicCandidate and API for Base64 decoding Changes: https://git.openjdk.java.net/jdk/pull/293/files Webrev: https://webrevs.openjdk.java.net/?repo=jdk&pr=293&range=00 Issue: https://bugs.openjdk.java.net/browse/JDK-8248188 Stats: 1925 lines in 24 files changed: 1899 ins; 4 del; 22 mod Patch: https://git.openjdk.java.net/jdk/pull/293.diff Fetch: git fetch https://git.openjdk.java.net/jdk pull/293/head:pull/293 PR: https://git.openjdk.java.net/jdk/pull/293
