There seems a few problems with the documentation here. First it
lists -mfp16-format= but it does not list what it does or even the
options it accepts. Second I don't see any specifications in the
documentation of __fp16 semantics or current issues you listed in the
0/8 email (like not allowed to use it as an argument or return value
of a function).
Thanks,
