uint32_t svqdecp[_n_u32]_b16(uint32_t op, svbool_t pg)
128-bit SVE
Considering only predicate bits from (1) corresponding to 16-bit elements, set (3) to (2) − popcount( (1) ), with unsigned saturation to zero.
256-bit SVE
Considering only predicate bits from (1) corresponding to 16-bit elements, set (3) to (2) − popcount( (1) ), with unsigned saturation to zero.
512-bit SVE
Considering only predicate bits from (1) corresponding to 16-bit elements, set (3) to (2) − popcount( (1) ), with unsigned saturation to zero.
