Should the following be added too? I was looking though the instructions with pseudos, this might not be all of them but these appear to be missing. I was hacking up the tests in llvm/unittests/Target/AArch64/AArch64SVESchedPseudoTest.cpp to try and see how many were present and what latencies they had. Some of the tests are hard to follow as there as so many variants of the same opcode nowadays.
