TBLQ: Programmable table lookup within each quadword vector segment (zeroing)

TBLQ Zd.S, { Zn.S }, Zm.S (SVE2.1 (SME2.1

128-bit SVE

Within each 128-bit segment, for each 32-bit index from (2), if 0 ≤ index < 4, set (3) to the 32-bit element at that index in the segment from (1), otherwise set (3) to zero.

256-bit SVE

Within each 128-bit segment, for each 32-bit index from (2), if 0 ≤ index < 4, set (3) to the 32-bit element at that index in the segment from (1), otherwise set (3) to zero.

512-bit SVE

Within each 128-bit segment, for each 32-bit index from (2), if 0 ≤ index < 4, set (3) to the 32-bit element at that index in the segment from (1), otherwise set (3) to zero.

Larger sizes

1024-bit SVE

Within each 128-bit segment, for each 32-bit index from (2), if 0 ≤ index < 4, set (3) to the 32-bit element at that index in the segment from (1), otherwise set (3) to zero.

2048-bit SVE

Within each 128-bit segment, for each 32-bit index from (2), if 0 ≤ index < 4, set (3) to the 32-bit element at that index in the segment from (1), otherwise set (3) to zero.
