Thanks for the pointer, which confirms it is much more complex than I anticipated. However, I still need to initialize the mask vector with GCC-vector notation, not using vld1 otherwise the compiler cannot detect if the mask vector is contant (and therefore suitable for an optimization). This makes writing exhaustive, portable (big and little endian), executable tests a painful task. Thanks
