> Can you extract this into its own patch as it's really not relevant to the rest of the patch and is currently missing tests. Presumably `llvm/test/CodeGen/AArch64/sve-insert-vector.ll` needs updating?
i've been adding some tests to assert this block of code. i've got tests for `insert(vscale x n x bfloat, n x bfloat, idx)` and `insert(vscale x n x bfloat, vscale x n x bfloat, idx)`.
the n = 4 and n = 8 tests are fine, but n = 2 for `insert(vscale x 2 x bfloat, 2 x bfloat, idx)` fails an assertion. i've had a quick poke around but haven't seen an obvious reason why its failing, should I worry about this and spend more time on it or just submit the tests i've already got for `4bf16` and `8bf16`?
