The internal enum jdk.internal.util.Architecture does not provide information about the big or little endianness or the address size (64 or 32 bits). The endian-ness and address size are intrinsic to the architecture.
The values of the enum are extended to separately identify the big endian and little-endian uses of the ISA. For example, `PPC64` and `PPC64LE` for the big and little-endian versions. The enum values directly reflect the build-time artifacts and resulting executables. This information about an architecture will make the enum more useful especially to identify a target platform in a cross-platform use case. A method is added to map well known aliases for the platforms to the Architecture enum. ------------- Commit messages: - 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=00 Issue: https://bugs.openjdk.org/browse/JDK-8308452 Stats: 134 lines in 4 files changed: 111 ins; 3 del; 20 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
