VQSUB
Vector Saturating Subtract.
Syntax
VQSUB{conddatatypeQdQnQm
VQSUB{conddatatypeDdDnDm
where:
condis an optional condition code.
datatypemust be one of
S8,S16,S32,S64,U8,U16,U32, orU64.Qd,Qn,Qmare the destination vector, the first operand vector, and the second operand vector, for a quadword operation.
Dd,Dn,Dmare the destination vector, the first operand vector, and the second operand vector, for a doubleword operation.
Operation
VQSUB subtracts the elements of one vector from the corresponding elements
of another vector, and places the results in the destination vector.
The sticky QC flag (FPSCR bit[27]) is set if saturation occurs.
