``__fp16`` is supported on every target, as it is purely a storage format; see below.
``_Float16`` is currently only supported on the following targets, with further
targets pending ABI standardization:
- 32-bit ARM
- 64-bit ARM (AArch64)
- SPIR
* 32-bit ARM
* 64-bit ARM (AArch64)
* SPIR
``_Float16`` will be supported on more targets as they define ABIs for it.
``__fp16`` is a storage and interchange format only. This means that values of

common real type of ``__fp16`` and ``_Float16`` for the purposes of the usual
arithmetic conversions is ``float``.
A literal can be given ``_Float16`` type using the suffix ``f16``; for example:

A literal can be given ``_Float16`` type using the suffix ``f16``. For example,
``3.14f16``.
Because default argument promotion only applies to the standard floating-point
types, ``_Float16`` values are not promoted to ``double`` when passed as variadic
