128-bit SVE

Convert each 64-bit float from (1) to a 16-bit float, writing the results to the lowest overlapping 16-bit lanes of (2), and zeroing other lanes. The current rounding mode selected by FPCR is used.
256-bit SVE

Convert each 64-bit float from (1) to a 16-bit float, writing the results to the lowest overlapping 16-bit lanes of (2), and zeroing other lanes. The current rounding mode selected by FPCR is used.
512-bit SVE

Convert each 64-bit float from (1) to a 16-bit float, writing the results to the lowest overlapping 16-bit lanes of (2), and zeroing other lanes. The current rounding mode selected by FPCR is used.
