Scott Gibbons has updated the pull request with a new target base due to a merge or a rebase. The incremental webrev excludes the unrelated changes brought in by the merge/rebase. The pull request contains eight additional commits since the last revision: - Merge branch 'openjdk:master' into Base64-AVX2 - Remove whitespace - Fix wrong register usage - Working version of Base64 decode with AVX2 (4x perf improvement). No URL support - Merge branch 'Base64-AVX2' of https://github.com/asgibbons/jdk into Base64-AVX2 - Merge branch 'openjdk:master' into Base64-AVX2 - Intermediate AVX2 for decode - Fix various AVX support function invocations to get Base64 generated for AVX2 ------------- Changes: - all: https://git.openjdk.org/jdk/pull/12126/files - new: https://git.openjdk.org/jdk/pull/12126/files/9cfa6bbd..0f4b9c88 Webrevs: - full: https://webrevs.openjdk.org/?repo=jdk&pr=12126&range=01 - incr: https://webrevs.openjdk.org/?repo=jdk&pr=12126&range=00-01 Stats: 4398 lines in 281 files changed: 2042 ins; 692 del; 1664 mod Patch: https://git.openjdk.org/jdk/pull/12126.diff Fetch: git fetch https://git.openjdk.org/jdk pull/12126/head:pull/12126 PR: https://git.openjdk.org/jdk/pull/12126
