URL: https://github.com/llvm/llvm-project/commit/ef30a00a57c78a91571a66555f2531af0f1f51e5 DIFF: https://github.com/llvm/llvm-project/commit/ef30a00a57c78a91571a66555f2531af0f1f51e5.diff LOG: [NFC] Add float aggregate ABI test for PowerPC 4c5a93bd landed adjustment to handle C++20 no_unique_address attribute correctly, clang treats empty members in aggregate type differently if having this attribute. This commit adds necessary test for PowerPC target to reflect this change.
