These are currently broken because the order of elements inside vectors is reversed on big-endian systems: the ARM ABI requires that element 0 is located at the highest address of the vector type. However LLVM intrinsics expect element 0 to be located at the lowest address. See https://llvm.org/docs/BigEndianNEON.html and `arm_neon.h` in Clang for more details. Although this is a breaking change, this is acceptable for 2 reasons: - big endian ARM targets are only tier 3. - it is preferable to stop existing code from compiling than to let it run and produce incorrect results. |
