SQDECP (vector): Signed saturating decrement vector by count of true predicate elements
SQDECP Zdn.H, Pm.H (SVE (SME
128-bit SVE
Count the non-zero predicate bits corresponding to 16-bit elements from (1), then subtract the total from each 16-bit element from (2), with signed saturation to −0x8000, setting (3) to the result.
256-bit SVE
Count the non-zero predicate bits corresponding to 16-bit elements from (1), then subtract the total from each 16-bit element from (2), with signed saturation to −0x8000, setting (3) to the result.
512-bit SVE
Count the non-zero predicate bits corresponding to 16-bit elements from (1), then subtract the total from each 16-bit element from (2), with signed saturation to −0x8000, setting (3) to the result.
