,Qm
are the destination vector, the first operand vector, and the second operand vector, for a quadword operation.
Dd
,Dn
,Dm
are 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.
