Sorry for the quiet on this. I'm going to abandon this for the moment, as what I eventually found was that there was some ambiguity in the ARM ABI regarding half-floats which would be better to address first, so that the attributes can map directly. There is currently only one ARM build attribute for denormals which reads as though it affects all precisions, but may not have been updated after half-float support was added. Since that maps to denormal-fp-math, which also controls all precisions, both may need splitting rather than just the function level attribute.
