[Qemu-devel] [PATCH v2 03/24] softfloat: Add 16 bit integer to float conversions

[Peter Maydell <peter.maydell@linaro.org>]

Add the float to 16 bit integer conversion routines. These can be
trivially implemented in terms of the int32_to_float* routines, but
providing them makes our API more symmetrical and can simplify callers.
