FCVTZS Zd.S, Pg/Z, Zn.D (SVE2.2 (SME2.2
128-bit SVE
Convert each 64-bit floating point value from (1) to a signed 32-bit integer, rounding towards zero, with signed saturation to 0x7FFFFFFF or −0x80000000, writing the results to the even lanes of (2), sign extending into the odd lanes.
256-bit SVE
Convert each 64-bit floating point value from (1) to a signed 32-bit integer, rounding towards zero, with signed saturation to 0x7FFFFFFF or −0x80000000, writing the results to the even lanes of (2), sign extending into the odd lanes.
512-bit SVE
Convert each 64-bit floating point value from (1) to a signed 32-bit integer, rounding towards zero, with signed saturation to 0x7FFFFFFF or −0x80000000, writing the results to the even lanes of (2), sign extending into the odd lanes.
