128-bit SVE

Convert each 64-bit floating point value from (1) to a signed 64-bit integer, rounding towards zero, with signed saturation to 0x7FFFFFFFFFFFFFFF or −0x8000000000000000, writing the results to (2).

256-bit SVE

Convert each 64-bit floating point value from (1) to a signed 64-bit integer, rounding towards zero, with signed saturation to 0x7FFFFFFFFFFFFFFF or −0x8000000000000000, writing the results to (2).

512-bit SVE
