Hi @stuij,

The changes to the backend only handle the half (f16) type itself, not vectors that have it as their base type.

>From what I've checked on the AAPCS, the rules for handling those types are a bit different and they would require their own handling in the backend's calling convention lowering.
I haven't looked into the backend's handling of those types in detail, but I believe a similar approach to the one taken for f16 would be possible for the vector types as well.
