Hi,
Conversions from double precision floats to the ARM __fp16 are required
to round only once.
This patch adds a functions named __gnu_d2h_ieee and
__gnu_d2h_alternative for double to __fp16 conversions in IEEE and ARM
alternative format. The make use of the existing __gnu_float2h_internal
conversion function which rounds once only.
Bootstrapped on an ARMv8-A machine with no issues, and cross-tested with
a range of multilibs.
OK?
Ok.
Thanks,
Kyrill
Thanks,
