Hi Matthew,
There are currently no FP16 instructions implemented in binutils, this
patch is to enable subsequent work on supporting the extension.
If this subsequent work is going to take some time, then please could
you update the patch to gas/doc/c-aarch.texi to point out that although
the command line option is active the feature is not yet implemented.

* config/tc-aarch64.c (aarch64_features): Add "fp16".
* doc/c-aarch64.texi (Architecture Extensions): Add "fp16".
