URL: https://github.com/llvm/llvm-project/commit/bce2cc15133a1458e4ad053085e58c7423c365b4 DIFF: https://github.com/llvm/llvm-project/commit/bce2cc15133a1458e4ad053085e58c7423c365b4.diff LOG: [clang] Set __GCC_*STRUCTIVE_SIZE on Aarch64 Before this change, we would set this to Clang's default of {64, 64}. Now, we explicitly set it to {256, 64} which matches our ARM behavior for ARMv8 targets and GCC's behavior for AArch64 targets.
