It seems to be broken after llvm/llvm-project@15fbdc2. The checks which fail now are produced by these lines:

if (has_sve()) {
// in native width, ld1b/st1b is used regardless of data type
const bool allow_byte_ls = (width == target.vector_bits);
add({get_sve_ls_instr("ld1", bits, bits, "", allow_byte_ls ? "b" : "")}, total_lanes, load_store_1);
add({get_sve_ls_instr("st1", bits, bits, "", allow_byte_ls ? "b" : "")}, total_lanes, load_store_1);
.

I tried to fix it, but I don't really now much about SVE2, so wasn't able to do anything smarter than commenting these line so far.
