Well, I think this is my surprise then. Thinking out loud: we're talking SVE here, which always implies FP16. That's why I am surprised that we bother with a storage-type only type. Looking at the SVE ACLE I indeed see: float16_t equivalent to __fp16 where I was probably expecting: float16_t equivalent to _Float16 and with that everything would be sorted I guess, then we also don't need the hack^W workaround that is `-fallow-half-arguments-and-returns`. But maybe there is a good reason to use/choose `__fp16` that I don't see here. Probably worth a quick question for the ARM SVE ACLE, would you mind quickly checking?
