The interpretation of maximum differs between GCC and Clang: Clang includes vector types too so for ARM GCC thinks the maximum alignment is 8 (for uint64_t), but Clang thinks its 16 (because there are NEON instructions that require 16-byte alignment). > > CONFIG_AARCH32_EMULATION, which I think is clearer than CONFIG_ARM64_AARCH32. > > there. from https://android.googlesource.com/platform/ndk/+/master/docs/ClangMigration.md#how-to-fix-common-problems: Normally the __aligned__ attribute is given an explicit alignment, but with no value means maximum alignment.
