128-bit SVE

Convert each 32-bit float from (1) to a BFloat16, writing the results to the odd 16-bit lanes of (3), preserving the even lanes from (2). The current rounding mode selected by FPCR is used.
256-bit SVE

Convert each 32-bit float from (1) to a BFloat16, writing the results to the odd 16-bit lanes of (3), preserving the even lanes from (2). The current rounding mode selected by FPCR is used.
512-bit SVE

Convert each 32-bit float from (1) to a BFloat16, writing the results to the odd 16-bit lanes of (3), preserving the even lanes from (2). The current rounding mode selected by FPCR is used.
