Roger Riggs has updated the pull request with a new target base due to a merge or a rebase. The pull request now contains eight commits: - Don't map ppc64le to ppc64 when processing the PlatformProps.java.template - Merge branch 'master' into 8308452-cross-platform-arch - Correct handling of ppc64le/ppc64 using non-canonical architecture. Keep canonical architecture names for s390, amd/x86_64. - Merge branch 'master' into 8308452-cross-platform-arch - Merge branch 'master' into 8308452-cross-platform-arch - Review suggestions - Correct address size for ARM (32-bit) - 8308452: Extend internal Architecture enum with byte order and address size ------------- Changes: https://git.openjdk.org/jdk/pull/14063/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=14063&range=02 Stats: 149 lines in 6 files changed: 116 ins; 19 del; 14 mod Patch: https://git.openjdk.org/jdk/pull/14063.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/14063/head:pull/14063 PR: https://git.openjdk.org/jdk/pull/14063
