128-bit SVE

Take the minimum across corresponding active signed 64-bit integer elements from each 128-bit segment of (1), storing the result in (3). For any element where the corresponding predicate bit in (2) is 0, interpret it as −0x8000000000000000.
256-bit SVE

Take the minimum across corresponding active signed 64-bit integer elements from each 128-bit segment of (1), storing the result in (3). For any element where the corresponding predicate bit in (2) is 0, interpret it as −0x8000000000000000.
512-bit SVE

Take the minimum across corresponding active signed 64-bit integer elements from each 128-bit segment of (1), storing the result in (3). For any element where the corresponding predicate bit in (2) is 0, interpret it as −0x8000000000000000.

1024-bit SVE

Take the minimum across corresponding active signed 64-bit integer elements from each 128-bit segment of (1), storing the result in (3). For any element where the corresponding predicate bit in (2) is 0, interpret it as −0x8000000000000000.
2048-bit SVE

Take the minimum across corresponding active signed 64-bit integer elements from each 128-bit segment of (1), storing the result in (3). For any element where the corresponding predicate bit in (2) is 0, interpret it as −0x8000000000000000.
