Hi, Much like the zip intrinsics, the vuzp_* intrinsics are implemented with inline ASM, which prevents compiler analysis. This series replaces those with calls to _builtin_shuffle, which produce the same** assembler instructions.
(**except for two-element vectors where UZP and ZIP are equivalent and the backend outputs ZIP.) First patch adds a bunch of tests, passing for the current asm implementation; Second patch reimplements with __builtin_shuffle; Third patch adds equivalent ARM tests using test bodies shared from first patch. OK for stage 1? Cheers, Alan
