128-bit SVE
For each 64-bit value integer set (2) to ( (1) & 0xFFFFFFFF ). This takes the low 32-bits of (1), and zero-extends it to 64-bit.
256-bit SVE
For each 64-bit value integer set (2) to ( (1) & 0xFFFFFFFF ). This takes the low 32-bits of (1), and zero-extends it to 64-bit.
512-bit SVE
For each 64-bit value integer set (2) to ( (1) & 0xFFFFFFFF ). This takes the low 32-bits of (1), and zero-extends it to 64-bit.

1024-bit SVE
For each 64-bit value integer set (2) to ( (1) & 0xFFFFFFFF ). This takes the low 32-bits of (1), and zero-extends it to 64-bit.
2048-bit SVE
For each 64-bit value integer set (2) to ( (1) & 0xFFFFFFFF ). This takes the low 32-bits of (1), and zero-extends it to 64-bit.
