Hi @Wanghuang-Huawei, thanks for adding the SVE support for VectorCast. I observed that this patch misses some type casts like: byte -> long, short -> long, long -> byte and long -> short. Do you have any plan to add these missing parts in future? I'd suggest to add them all with the single patch. WDYT?
