FCVTZS Zd.S, Pg/M, Zn.D (SVE (SME

svint32_t svcvt_s32[_f64]_m(svint32_t inactive, svbool_t pg, svfloat64_t op)

## 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.

## 1024-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.

## 2048-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.
