I've found a way to solve the remaining FFI problem on linux PPC64 Big Endian. Large structs (>8 Bytes) which are passed in registers or on stack require shifting the Bytes in the last slot if the size is not a multiple of 8. This PR adds the required functionality to the Java code.
Please review and provide feedback. There may be better ways to implement it. I just found one which works and makes the tests pass: Test summary ============================== TEST TOTAL PASS FAIL ERROR jtreg:test/jdk/java/foreign 88 88 0 0 Note: This PR should be considered as preparation work for AIX which also uses ABIv1. ------------- Commit messages: - 8314949: linux PPC64 Big Endian: Implementation of Foreign Function & Memory API Changes: https://git.openjdk.org/jdk/pull/15417/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=15417&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8314949 Stats: 235 lines in 10 files changed: 225 ins; 5 del; 5 mod Patch: https://git.openjdk.org/jdk/pull/15417.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/15417/head:pull/15417 PR: https://git.openjdk.org/jdk/pull/15417
